Abstract

The invention is applicable to the technical field of vehicle bench testing and provides a wheel steering following control system, which comprises a sensor device, a control device, a following actuator and a roller device. The sensor device comprises a first sensor and a second sensor, wherein a first distance to the wheel is detected through the first sensor, and a second distance to the wheelis detected through the second sensor; the control device obtains roller controlled quantity according to the first distance, the second distance and current roller steering angle; the following control mechanism drives the roller device to steer according to the roller controlled quantity so that the difference between the roller steering angle and the wheel steering angle of the wheel meets a preset angular difference condition. The wheel steering following control system in the invention controls a drive mechanism to change the roller steering angle according to the wheel steering angle andthe current roller steering angle so that the roller device follows the wheel to rotate in real time so as to reduce yawing force received by the wheel in the steering process; the position between the wheel and the roller is kept to be relatively stable; and the vehicle is ensured to normally steer during driving on a rack.

Description

technical field [0001] The invention belongs to the technical field of vehicle bench testing, in particular to a wheel steering follow-up control system. Background technique [0002] With the development of Internet + and mobile communication technology, the Internet of Vehicles has been widely used in the automobile manufacturing industry on a large scale, which not only makes intelligent transportation a reality, but also makes automatic driving possible. Autonomous driving will be the main direction of future automobile development. [0003] The emergence of self-driving cars puts forward new requirements for the existing test methods. When performing bench simulation tests on vehicles, because the steering has an impact on the vehicle's attitude, driving resistance, and driving experience, it is necessary to turn the steering during the test. , especially when autonomous vehicles simulate real-world road conditions. [0004] When a moving vehicle is turning on the pla...
