2. China drive-by-wire standard 2026: what is GB17675-2025 and what exactly changes in requirements for steering systems.

Let’s dive into the heart of the China drive-by-wire standard 2026: the GB17675-2025 steering systems regulation. Officially titled “Steering System of Motor Vehicles—Basic Requirements,” this national standard was released by China’s Standardization Administration on December 2, 2025, and becomes effective July 1, 2026. It replaces the previous GB17675-2021 version, updating the rules for how vehicles handle steering to accommodate modern technologies like electric vehicles and autonomous features.

So, what is GB17675-2025 exactly? It’s a comprehensive document that outlines terms, definitions, technical requirements, and test methods for automotive steering systems. It applies primarily to M1 (passenger cars) and N1 (light trucks) vehicles, ensuring they meet safety and performance benchmarks. Drawing from official sources like the MIIT and SAC, the standard specifies everything from steering control equipment to actuators, emphasizing electronic integration over traditional mechanics.

The big changes? First, it eliminates the mandatory mechanical connection between the steering wheel and wheels, a rule that dated back to older standards. In GB17675-2021, vehicles needed a physical linkage as a safety net. Now, full electronic steer-by-wire systems are permitted without it, as long as they comply with enhanced safety protocols. This opens doors for drive-by-wire innovations, where steering is managed via sensors, electronic control units (ECUs), and motors.

Other updates include refined test methods for failures, such as measuring steering effort when systems degrade. For instance, it introduces specific criteria for full-power steering systems, requiring warnings for issues like battery aging that could affect control. The standard also incorporates functional safety from ISO 26262, mandating that electronic systems achieve certain integrity levels to prevent hazards.

Why these changes matter: They standardize steer-by-wire across manufacturers, reducing fragmentation. Companies like NIO, which contributed to drafting, can now mass-produce vehicles like the ET9 without special approvals. Tests now cover extreme conditions—vibrations, temperatures, and electromagnetic interference—to ensure reliability.

In essence, GB17675-2025 steering systems modernize regulations to support China’s EV boom. It’s not just about removing parts; it’s about building trust in electronic alternatives through rigorous requirements. If you’re an auto enthusiast, this means cars that are lighter, more efficient, and ready for the future— all backed by official, vetted standards.

3. China drive-by-wire standard 2026: steer-by-wire becomes legal — in simple terms, without “engineering snobbery”.

Under the China drive-by-wire standard 2026, steer-by-wire becomes fully legal, and we’ll explain it in straightforward language—no need for fancy jargon. Essentially, steer-by-wire is a technology where your steering inputs are translated into electronic signals that tell the wheels what to do, ditching the old-school metal rods and columns. The steer-by-wire standard China has adopted via GB17675-2025 makes this the new norm starting July 1, 2026.

Picture this: In a traditional car, turning the wheel physically pulls on linkages to move the tires. It’s reliable but bulky and limits design flexibility. Steer-by-wire swaps that for sensors on the wheel that detect your movements, send data to a computer (ECU), and activate motors at the wheels to turn them. It’s like how a game controller works—quick, precise, and adjustable.

Why is this now legal? The previous rules required a mechanical backup for safety, but GB17675-2025, released by SAC, removes that mandate. As long as the system meets safety checks, it’s good to go. Official documents from MIIT highlight that this allows for better handling, like changing how sensitive the steering feels based on speed—snappy in parking lots, smooth on freeways.

In simple terms, it’s safer than it sounds because of built-in backups. If something glitches, redundant systems kick in to keep you in control. No more worrying about a snapped shaft; instead, the car warns you and degrades gracefully, maybe slowing down while you pull over.

This steer-by-wire standard China is pushing aligns with global shifts, referencing UN R79 for uniform rules. For drivers, it means cars that vibrate less (filtered feedback), turn tighter in cities, and integrate with autonomous tech. Brands like BYD and Geely are gearing up, making EVs more appealing.

Overall, it’s an exciting step toward cars that drive themselves part-time. No engineering degree needed—just know it’s making driving easier, safer, and more fun, all thanks to China’s forward-thinking regulations.

4. China drive-by-wire standard 2026: date and market — why July 1, 2026 is more important than any brand presentation.

The China drive-by-wire standard 2026 hinges on a key date: steer-by-wire July 1 2026, when GB17675-2025 officially kicks in. This isn’t just a calendar note; it’s a pivotal moment that outshines flashy brand launches because it sets the rules for the entire market.

Why this date? Released December 2, 2025, by SAC, the standard gives manufacturers about seven months to adapt. From July 1, 2026, all new vehicles must comply if using steer-by-wire, ensuring uniformity. MIIT sources explain this timeline allows testing and certification, preventing rushed implementations that could compromise safety.

Market-wise, it’s huge for China’s EV sector, the world’s biggest. Steer-by-wire July 1 2026 means companies can certify full electronic steering without mechanical links, boosting innovation. Before, models like NIO’s ET9 needed individual approvals; now, it’s standardized, speeding up production and reducing costs.

This date trumps brand events because it’s regulatory, not promotional. A Tesla reveal might wow crowds, but without standards, tech stays niche. GB17675-2025 enables mass adoption, potentially growing steer-by-wire penetration to 30% by 2030, per industry predictions from sources like all-about-industries.com.

It impacts suppliers too—firms like Nexteer, involved in drafting, can scale redundant systems. For consumers, it means more options: lighter cars, better fuel efficiency, and features like retractable wheels for autonomy.

5. China drive-by-wire standard 2026: “the steering wheel not connected to wheels” — how it works (sensors, ECU, actuators) and why it’s closer to a gamepad than classics.

In the China drive-by-wire standard 2026, the concept of a steering wheel not connected to wheels is central—it’s all electronic, no physical ties. Let’s unpack how it works in easy steps.

First, sensors: When you turn the wheel, angle and torque sensors detect the motion and force. These are like your gamepad’s joysticks, capturing inputs precisely without mechanical drag.

Next, the ECU (electronic control unit): This brain processes sensor data, considering speed, road conditions, and vehicle dynamics. It runs algorithms to decide how much the wheels should turn, drawing from ISO 26262 standards for reliability, as per SAC documents.

Then, actuators: Electric motors at the wheels or rack execute the command, turning the tires. No shafts or columns—just wires and signals.

Why like a gamepad? Classics rely on direct force transfer, feeling raw but limiting. Steer-by-wire simulates feedback via motors in the wheel, vibrating to mimic road feel, but filters out bumps for comfort. It’s customizable—adjust ratios for sporty or relaxed driving, per MIIT guidelines.

The steering wheel not connected to wheels frees designs, enabling foldable wheels for autonomy. Safety comes from redundancy: dual sensors and ECUs ensure backup, as mandated in GB17675-2025.

This setup, closer to gaming tech, enhances EVs—lighter weight, quicker response. Official tests confirm it under extremes, making it trustworthy. It’s a fun, modern twist on driving.

6. China drive-by-wire standard 2026: safety — what failure scenarios are critical and how requirements/tests cover them.

Safety is paramount in the China drive-by-wire standard 2026, with steer-by-wire safety requirements built to handle worst-case scenarios. GB17675-2025, from SAC, outlines protocols to prevent disasters.

Critical failures? Power loss: If the battery fails, steering could vanish. Controller faults: ECU glitches might misinterpret inputs. Signal disruptions: Electromagnetic interference could scramble data.

How covered? The standard mandates redundancy—dual power supplies and ECUs for fail-operational mode, per ISO 26262. In failures, systems degrade gracefully: Maintain partial control, warn drivers via alarms, and slow the vehicle safely.

Tests, detailed in MIIT documents, simulate extremes: High temperatures, vibrations, and faults. For example, measure steering effort post-failure to ensure controllability. Additional checks for full-power systems verify warnings for battery issues.

Steer-by-wire safety requirements align with UN R79, requiring ASIL levels for integrity. Manufacturers submit docs for review, with random verifications.

This ensures even in critical scenarios, like sudden power cut, backups engage seamlessly. It’s why models like ET9 pass certifications—proven safe beyond mechanics.

7. China drive-by-wire standard 2026: redundancy (fail-operational) — power, communication channels, duplication, why “one brain” isn’t enough.

The China drive-by-wire standard 2026 places significant emphasis on fail-operational steering redundancy to ensure vehicle controllability under various conditions. As outlined in GB17675-2025, issued by the Standardization Administration of China (SAC) on December 2, 2025, and effective from July 1, 2026, the standard mandates duplication of critical components to prevent any single failure from compromising steering functionality. This approach aligns with international benchmarks such as ISO 26262 for functional safety and UN R79 for steering system regulations, as referenced in official documents from the Ministry of Industry and Information Technology (MIIT).

A single electronic control unit (ECU), often referred to as the system’s “brain,” is insufficient because its failure could result in complete loss of steering control, posing substantial safety risks. To address this, GB17675-2025 requires redundant architectures, including dual ECUs that operate in parallel, allowing seamless switchover if one unit malfunctions. This duplication extends to sensors and actuators, ensuring that steering inputs are reliably processed and executed.

Regarding power supply, the standard necessitates dual independent sources, such as separate batteries or converters, to mitigate blackout scenarios. Backup energy storage is mandatory to maintain steering capability during primary system failures, thereby supporting fail-operational performance where the vehicle remains drivable even in degraded states.

Communication channels are similarly fortified through redundant pathways, such as multiple Controller Area Network (CAN) buses, to safeguard against signal transmission errors caused by electromagnetic interference or faults. These measures ensure uninterrupted data flow between the steering wheel, ECUs, and wheel actuators.

Duplication of components, as specified by SAC guidelines, includes mirrored motors and sensors to achieve high reliability. In the event of a failure, the system transitions to a backup mode without abrupt changes in steering angle, maintaining control forces within defined limits per Table 2 of the standard.

Safety tests, detailed in MIIT publications, involve simulating faults to verify degradation times, alarm activations, and overall system resilience under extreme conditions like high temperatures and vibrations. These protocols confirm alignment with ISO 26262’s Automotive Safety Integrity Levels (ASIL).

Fail-operational steering redundancy is particularly vital for advanced autonomous driving applications, where human intervention may be limited. This is why reliance on a single “brain” is inadequate; comprehensive duplication fosters reliability, as demonstrated in systems like those from NIO, which achieve failure rates as low as 4.5 FIT (failures in time) per billion hours, according to industry reports.

8. China drive-by-wire standard 2026: cybersecurity — threats, updates, access control, “don’t turn the steering into a Wi-Fi joke”.

Cybersecurity constitutes a critical aspect of the China drive-by-wire standard 2026, with steer-by-wire cybersecurity requirements designed to protect against potential vulnerabilities. Although GB17675-2025, released by the SAC on December 2, 2025, primarily addresses functional safety, it integrates with broader automotive cybersecurity frameworks such as ISO/SAE 21434, as noted in MIIT contexts. This integration ensures that electronic steering systems are resilient in an increasingly connected vehicle ecosystem.

Potential threats include remote hacks targeting connected ECUs, which could enable unauthorized manipulation of steering commands. Malware infections might disrupt signal integrity, while spoofing attacks could introduce false inputs, compromising vehicle control.

To counter these, the standard supports over-the-air (OTA) updates as a mandated mechanism for addressing vulnerabilities promptly, ensuring compliance with evolving security protocols. Access control is enforced through secure gateways that restrict entry points, employing encryption and multi-factor authentication to prevent unauthorized intrusions.

Systems are designed to isolate critical steering functions from non-essential components, such as infotainment networks, thereby avoiding scenarios where steering becomes susceptible to external wireless interference. Redundancy further enhances protection: if one communication channel is compromised, isolated backups maintain operational integrity.

Testing procedures incorporate penetration simulations and vulnerability assessments, as aligned with ISO/SAE 21434 guidelines, to validate system resilience. These evaluations are conducted under MIIT oversight to ensure that steer-by-wire implementations withstand real-world cyber threats.

Steer-by-wire cybersecurity requirements continue to adapt to emerging risks, safeguarding China’s electric vehicle sector in a digitally interconnected environment. By adhering to these measures, manufacturers can uphold the integrity of drive-by-wire technologies, contributing to overall vehicle safety and reliability.

9. China drive-by-wire standard 2026: design without steering column — foldable wheel, new interiors, prep for autonomy.

The China drive-by-wire standard 2026 facilitates designs without a steering column, fundamentally altering vehicle architecture. GB17675-2025, promulgated by the SAC on December 2, 2025, permits the elimination of mechanical linkages, thereby enabling innovative configurations that enhance spatial efficiency and functionality.

Foldable steering wheels represent a key advancement: without rigid columns, the wheel can retract into the dashboard, optimizing interior space for passenger comfort during autonomous modes. This feature is supported in SAC documentation for vehicles achieving Level 3 autonomy and beyond, where manual controls may be temporarily disengaged.

New interior layouts benefit from the additional freedom, allowing for expanded legroom and adaptable seating arrangements, such as swivel chairs or integrated workspaces. This shift prepares vehicles for full self-driving capabilities, rendering traditional steering wheels optional in certain operational contexts.

Safety is preserved through electronic redundancy, as stipulated by MIIT requirements, ensuring that control remains robust despite the absence of mechanical components. The no-steering-column design also reduces vehicle weight, improving energy efficiency and performance, particularly in electric vehicles.

Manufacturers like XPeng have adopted these principles, developing models that leverage the standard to create more versatile and forward-looking automobiles. Overall, this regulatory evolution promotes innovation while maintaining stringent safety standards.
