Abstract

The invention provides a brake control method, an electronic stability control system and a computer readable medium. The method comprises the steps that a brake master cylinder is switched on to be in hydraulic connection with a first-side front wheel brake and to be in hydraulic connection with a first-side rear wheel brake; when a brake signal is received, the brake master cylinder can generateregenerated brake force for the first-side front wheel brake and the first-side rear wheel brake. According to the brake control method, the electronic stability control system and the computer readable medium, the problem in the prior art that the recovery amount of brake energy is low is solved; when a driver steps on a brake pedal, the intervention of friction brake is stopped, a regenerated brake motor converts partial kinetic energy generated when a vehicle is braked into energy of other forms, and then the energy is stored in an energy storage unit through a converting device; meanwhile, the speed reduction control over the vehicle is achieved through the generation of certain brake force, thus recycling of the brake energy is promoted, and the waste of the brake energy is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a braking control method, an electronic stability control system and a computer readable medium. Background technique [0002] The braking system is a special device that exerts a certain external force on a certain part of the car, so as to realize the forced braking of the wheels of the car to a certain extent. The cars running on the ramp keep running at a steady speed, so that the stopped cars can be parked stably. [0003] The service brake system is operated by the driver with his feet, so it is also called the foot brake system. Its function is to slow down the moving car or stop it in the shortest distance. The parking brake system is controlled by the driver's hand, so it is also called the hand brake system. Its function is to make the car parked on various road surfaces stay in place. The second brake system refers to a set of devices to ensure that the car can s...
