The invention provides a brake pedal. Two angle sensors and a pressure sensor are adopted by the brake pedal. The depth, the acting force and the acceleration generated when the brake pedal is trodden can be collected, and diversified brake pedal state information can be provided for a vehicle control unit. The brake pedal further comprises a brake pedal controller. The brake pedal controller collects signals of the two angle sensors and signals of the pressure sensor and conducts filtering processing on the collected signals, the reliability of the signals is improved, the processed signals are analyzed, brake pedal state information and fault diagnosis information are generated, the brake pedal state information is converted into an analog signal which is transmitted to the vehicle control unit through a signal output circuit, and the brake pedal state information and the fault diagnosis information are transmitted to the vehicle control unit through a CAN module in a CAN bus signal mode, so that the vehicle control unit carries out signal checking conveniently, and the fault state of the brake pedal can be judged more accurately.
Description
technical field [0001] The invention relates to the technical field of automobile braking, and more specifically, to a brake pedal controller, a brake pedal signal processing method and a brake pedal. Background technique [0002] With the increasing popularity of automobiles, people pay more and more attention to automobile safety. Among the safety problems of automobiles, the problem of braking safety is particularly prominent. [0003] At present, most electric vehicles use the brake pedal of a traditional car. The brake pedal uses two mechanical contact switches to judge whether the brake pedal is stepped on. Specifically, the two mechanical contact switches are normally open. The other one is normally closed, and the two switches check each other. [0004] However, the traditional brake pedal can only send signals to the vehicle controller through the above-mentioned mechanical contact switch to judge whether the brake pedal is stepped on, but cannot judge the depth, a...
