Abstract

The invention discloses a braking device adopting a magnet brake to realize a vehicle locking prevention function and a control method. An oil return solenoid valve, an oil inlet solenoid valve, a braking pipeline pressure sensor, a wheel speed sensor and a braking pedal position sensor are connected with an integrated control unit through wire harnesses respectively; the integrated control unit collects the signals of the braking pipeline pressure sensor and the braking pedal position sensor to determine a target braking torque, distributes friction braking torque and electromagnetic braking torque reasonably, realizes a wheel locking prevention function through torque regulation of a magnet brake, and achieves the vehicle locking prevention function by utilizing the magnet brake; and the magnet brake participates in shunting of vehicle braking energy in the whole braking process, so that the braking is rapider and more stable, the braking noise is lower, poisonous friction dust produced by friction braking can be greatly reduced, the safety and the thermal failure prevention performance of a braking system are improved, the service life of the braking system is prolonged, and the maintenance cost of the braking system is reduced.

Description

technical field [0001] The invention relates to a vehicle braking anti-lock braking device, in particular to a braking device and a control method for realizing the vehicle braking anti-lock braking function by adjusting the magnitude of the electromagnetic braking torque through the joint action of friction braking and electromagnetic braking . Background technique [0002] At present, the brake anti-lock function of the vehicle is realized by adjusting the braking torque of the friction brake. Although this technology is relatively mature, there are still some disadvantages in this braking system, such as: frictional braking noise is large, braking is not stable; mass inertia of liquid and gas in the brake pipeline will cause braking The response speed becomes slow; the continuous wear of the friction plate produces a large amount of toxic friction dust, and frequent brake wear increases the maintenance cost; in the case of continuous braking, the temperature of the brake...
