Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive wheel speed monitoring technology, specifically relating to a vehicle wheel speed adjustment simulation device. Background Technology
[0002] As the number of cars on the road continues to rise, consumers are demanding increasingly stringent safety technologies, especially active safety technologies. Currently, systems such as Anti-lock Braking System (ABS), Electronic Stability Program (ESP), and the increasingly popular Advanced Driver Assistance Systems (ADAS) and Forward Collision Warning Systems (FCWS) all heavily rely on the accurate acquisition of wheel speed information. These systems either directly use the current wheel speed measured by wheel speed sensors or use the vehicle's electronic control unit (ECU) to perform logical processing on the wheel speed signals to estimate the vehicle's speed.
[0003] As vehicle active safety technologies become increasingly widespread and mature, the measurement accuracy of wheel speed sensors is also constantly improving. From the original passive wheel speed sensors to active wheel speed sensors, their structures have become increasingly complex. At the same time, wheel speed sensors often operate in harsh environments such as vibration and humidity, which places higher demands on the development of controllers for various automotive control systems.
[0004] During the bench testing phase, software simulation or hardware simulation is primarily used to verify the correctness of the control strategy algorithm. This is especially true for brake controllers, as traditional real-vehicle testing is highly dangerous, and the complete verification process of the control strategy is extremely difficult. Most researchers use High-Input Wheel Speed (HIL) testing to reduce real-vehicle testing. Wheel speed signals are crucial input parameters in such controllers, and HIL testing requires obtaining signals as close to real-world conditions as possible. This approach simultaneously verifies the correctness and reliability of the control strategy, and by utilizing actual wheel speed sensors to acquire wheel speed signals, it also allows for fault simulation experiments of the wheel speed signals. However, current bench testing facilities lack such simulation equipment. Summary of the Invention
