Embodiment Construction

[0029] Referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention include the shape, structure, mutual position and connection relationship of each part, the function and working principle of each part, and the manufacturing process of the various components involved. And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0030] Such as figure 1 As shown, the vehicle controller (VCU) notifies the driver of the fault status of the brake switch signal through the instrument, collects the driver's operation intention, and responds to the driver's operation in real time. Each brake switch has four PIN pins, of which PIN2 and PIN3 are output and connected to VCU, and PIN1 and PIN4 are input and electrically connected to ve...

Abstract

The invention discloses an automobile double-brake-switch control system which is characterized in that an automobile is provided with two brake switches to obtain brake pedal signals, the two brake switches are connected with a VCU and output signals to the VCU, and the VCU obtains the signals of the two brake switches to judge whether brake faults exist or not. According to the invention, a double-brake-switch scheme is adopted, and a mutual verification function of two brake switches is added in the double-brake switch scheme, so that the situation of fault false alarm can be filtered, and the disadvantage of imperfect fault detection and judgment of a single-brake-switch scheme is made up; potential safety hazards and some unnecessary troubles caused by abnormal signals of the brake switch are effectively reduced, and the vehicle using convenience and safety of a user are improved.

Description

technical field [0001] The invention relates to the technical field of automobile braking. Background technique [0002] With the development trend of electrification and intelligence in the automobile market, on-board functions are becoming more and more complex, which makes the brake switch signal more and more important. In addition to some basic functions (such as: vehicle start, gear control, braking energy In addition to functions such as recycling, creeping, etc.), there is also an ADAS function whose dependence on the brake switch signal is not weaker than any of the above-mentioned functions, and the brake signal is closely related to driving safety. When the brake switch signal is abnormal, there will be safety hazards, and there is currently no system that can reliably solve this problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize an automobile dual brake switch control system and a diagnosis met...
