Abstract

The invention relates to the field of vehicle braking and discloses a brake pedal assembly and a vehicle. The brake pedal assembly comprises a pedal arm (1), a rotating shaft (2) connected to the pedal arm (1) and a brake lamp switch part (3). The brake lamp switch part (3) comprises a circuit board (31), a rotating piece, a magnet (38) and a Hall chip arranged on the circuit board (31). The rotating shaft (2) can drive the rotating piece to rotate so as to change a magnetic field formed by the magnet (38), and the Hall chip can sense a variable quantity and a variable speed of the magnetic field. According to the brake pedal assembly, a pivoting angle and a pivoting speed of the pedal arm are measured and reflected in a mode that the Hall chip is matched with the magnet, the position of the magnet corresponding to a new initial position of the pedal arm can be redefined even if the pedal arm is loosened and sinks, and a problem that a brake lamp switch cannot be normally turned off after the pedal arm is loosened is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a brake pedal assembly and a vehicle. Background technique [0002] The brake light switch is installed on the brake pedal bracket. When the vehicle needs to decelerate, stop or emergency brake, the brake switch is turned on and off synchronously when the driver depresses the brake pedal. When the brake switch is turned on, the brake lights at the rear of the car are always on, especially when the car needs to brake at high speed, the brake lights can remind the rear vehicles to slow down in time and take necessary emergency measures. Prevent accidents from happening. [0003] Most of the brake light switches are mechanical switches, which are generally controlled by moving contacts and static contacts. The installation method is mostly screwed, and the brake light switch is installed on the bracket on the brake pedal. When the pedal is not depressed, the push rod of th...
