In the field of declaration, intelligent chassis has unique advantages: 1.
Low speed control: reverse deflection of rear wheel and front wheel at low speed reduces turning radius.
parking is easier / city driving is more flexible.
change instantaneous rotation center. 2. High-speed control: at high speed, the rear wheel and the front wheel deflect in the same direction to improve the stability.
it can improve the lateral acceleration response of the vehicle.
improve the yaw damping 3.
Emergency avoidance: in the process of emergency collision avoidance, coordinate control with the front wheel steering to improve the stability of the vehicle. 4. Function expansion: cooperate with advanced auxiliary driving system and vehicle dynamic control system to support high-level automatic driving and ensure stability.
Application scenarios: 1.
Urban driving: on busy urban roads, vehicles need to turn frequently.
Rear wheel steering technology can significantly reduce the turning radius of vehicles, make vehicles more flexible, and facilitate turning and avoiding in narrow streets and busy intersections. 2. High-speed driving: on the highway, vehicles need to change lanes quickly and steadily.
Rear wheel steering technology can improve the stability and steering accuracy of vehicles, make vehicles more safe and stable at high speed, and reduce the risk of traffic accidents caused by improper lane change. 3. Complex road environment: in the sections with many mountain roads, bends or poor road conditions, rear wheel steering technology can help vehicles to complete steering operation more accurately, avoid side slippage or out of control, and improve driving safety. 4. Backing up into the warehouse: the rear wheel steering technology can also improve the accuracy and controllability of the vehicle when reversing into the warehouse, so that the driver can more easily grasp the direction and turning radius of the vehicle and avoid scratching or collision.
5, pull goods transportation: in the pull goods transportation, the vehicle needs to carry on the frequent steering and adjustment.
Rear wheel steering technology can make vehicles more flexible, improve transport efficiency, and reduce the risk of cargo damage and traffic accidents.
Future prospects: 1.
Development of autopilot: with the continuous progress of autopilot technology, rear wheel steering will play a more important role in improving vehicle path tracking ability and overall stability.
Self-driving vehicles need more accurate and flexible steering systems to cope with a variety of complex driving scenarios, and rear wheel steering technology is one of the important technologies to meet this demand. 2. The popularity of new energy vehicles: with the continuous expansion of the new energy vehicle market, rear wheel steering technology will be more widely used.
New energy vehicles have higher requirements for maneuverability and stability, and rear wheel steering technology can improve vehicle handling and stability, thus improving driving experience and safety. 3. The trend of intelligence and electrification: the electrification and intellectualization of rear wheel steering technology is the development trend in the future.
By controlling the left and right movement of the steering rod by the motor, the rear wheel steering function in the “real sense” can be realized, which can improve the control accuracy and response speed.
At the same time, the application of intelligent technology can also achieve more intelligent steering assistance and autopilot functions. 4. Cost reduction and popularization: with the progress of technology and the intensification of market competition, the cost of rear wheel steering technology will be gradually reduced, so that more models can carry this technology.
This will contribute to the popularization of rear wheel steering technology and improve the level of the entire automobile industry.
