Introduction

China Automotive Systems, Inc. (CAAS) has recently announced a groundbreaking innovation in the automotive technology space—the introduction of rear-wheel active steering technology designed specifically for upper mass-market electric vehicles (EVs) in China. With electric vehicles rapidly gaining traction and becoming a focal point in the automotive industry, CAAS' latest development promises to enhance the driving experience for a broader audience, moving beyond luxury cars to reach the upper mass-market segment.

Overview of the Technology

The new rear-wheel steering system is a product of CAAS' subsidiary, Jingzhou Henglong Automobile Parts Manufacturing Co., Ltd. The system employs a sophisticated ball screw and nut mechanism that integrates a control unit to process data from signals such as vehicle speed and steering wheel angle. This innovative mechanism drives a motor which then actuates the steering rod to maneuver the rear wheels effectively.

Enhanced Driving Dynamics

What sets this steering system apart is its dual-mode operation, allowing for adaptive steering strategies based on vehicle speed:

• - Low-Speed Operation: At speeds below 60 km/h, the rear wheels turn in the opposite direction relative to the front wheels. This adjustment effectively shortens the vehicle's effective wheelbase, facilitating a better turning radius for improved maneuverability in tight spaces.
• - High-Speed Operation: When traveling above 60 km/h, the rear wheels align in the same direction as the front wheels, simulating an extended wheelbase. This configuration greatly enhances vehicle stability during high-speed maneuvers, such as cornering and lane changes, thereby reducing the chances of drifting.

Versatility in Design

Jingzhou Henglong has established a dedicated production line for this advanced rear-wheel steering system and has already developed multiple configurations tailored for various original equipment manufacturer (OEM) models. Features such as flexible steering and enhanced vehicle stability make it a standout option for manufacturers looking to innovate.

Industry Recognition

The capability of the active rear-wheel steering system was prominently showcased at the 2025 Shanghai Auto Show, where dynamic demonstrations of prototype vehicles drew significant attention. This event served as a platform for CAAS to strengthen its relationships with leading OEMs, demonstrating the potential impact of their cutting-edge steering technologies on the automotive landscape.

Market Perspective

The emergence of this technology is particularly prompt as electric vehicles now account for approximately 50% of new automobile sales in China. Mr. Qizhou Wu, CEO of CAAS, noted the profound growth of the EV market and the company's strategic positioning to capitalize on these trends. The implementation of the rear-wheel steering system expands CAAS' Advanced Driver Assistance Systems (ADAS) capabilities, marking a notable evolution in their product offerings.

Competitive Advantage

What differentiates CAAS' system from conventional active rear-wheel steering systems is its use of two independently controlled motors. This advanced mechanism allows for precise adjustments to the steering angle of each rear wheel, providing both drivers and manufacturers with an unprecedented level of control and adaptability in vehicle handling.

Conclusion

In conclusion, CAAS is not merely keeping pace with the rapid technological advances in the automotive industry; it is leading the charge with innovations like rear-wheel active steering. This technology not only exemplifies a significant step forward in vehicle dynamics for upper mass-market EVs but also showcases CAAS' commitment to enhancing the driving experience for consumers in China and beyond. As the demand for electric vehicles continues to rise, CAAS is well-positioned to remain at the forefront of this transformative era in the automotive market.
