Safety braking device and method applied when vehicle suddenly encounters obstacle during high-speed running

Abstract

The invention relates to a safety braking device and method applied when a vehicle suddenly encounters an obstacle during high-speed running. The safety braking device comprises disc brakes arranged on wheels. The disc brakes comprise brake discs and calipers. The safety braking device is characterized by also comprising an electronic control unit (ECU), a speed sensor and a steering wheel angle sensor. The speed sensor and the steering wheel angle sensor are electrically connected with the ECU. The safety braking device also comprises at least one pair of bar-type magnets arranged on an axle and positioned on the both sides of the brake discs, and the ECU is electrically connected with coils of the bar-type magnets of the wheels through a multiplexer switch. By applying the braking device, the speed can be decreased rapidly, the yawing moment is effectively compensated, and drifting and overturning are avoided. The invention also relates to a safety braking method which can automatically assist the traditional disc brake way in rapidly decreasing the speed and effectively compensating the yawing moment.

Description

technical field [0001] The invention relates to a safety braking device and a method thereof when an automobile suddenly encounters an obstacle while running at high speed. Background technique [0002] When the car is running at high speed, if an obstacle suddenly appears in front of the car, the driver generally drives the traditional disc brake to work by stepping on the brakes, so as to convert the kinetic energy of the high-speed car into heat energy, so as to slow down and stop the car. , but in the case that the effective braking distance of the car is not enough, the driver's handling method will appear in the following two situations: (1) Considering that slamming the steering wheel will cause dangerous situations such as tail flicking and rollover, the car will crash into it while decelerating; (2) subconsciously want to avoid obstacles, and slam the steering wheel; the results of these two handling methods are very dangerous, and will cause serious injury to the v...
