Description

technical field [0001] The invention relates to the technical field of automobile braking simulation technology, in particular to a force-sensing simulation device for an automobile braking auxiliary system. Background technique [0002] The force feedback of some existing braking simulation systems is mostly realized only through springs, so the force feedback effect is single, the force is relatively stiff, and the noise is large, and the driving experience is poor. Therefore, there is an urgent need for a device that can change this situation. It has a real force-sensing simulation device of the automobile brake assist system. [0003] According to the above-mentioned problems, the present invention proposes a force-sensing simulation device for an automobile brake assist system. By setting a hydraulic cylinder in the device, these shortcomings of the spring-only one can be improved, and the spring cannot be realized. The brake assist function monitors the flow rate and ...
