Embodiment Construction

[0037] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0038] figure 1 It is a flowchart of a vehicle braking control method provided by an exemplary embodiment. Such as figure 1 As shown, the method may include the following steps:

[0039] Step S11, acquiring a braking signal of the vehicle.

[0040] The braking signal may be an electrical signal triggered by the driver operating a braking device (eg, a brake pedal) provided in the vehicle and used to instruct to control the braking of the vehicle. In a vehicle installed with an electronic brake system (Electronic Brake Systems, EBS), the braking signal of the vehicle can be obtained directly from the EBS.

[0041] Step S12, determining expected braking st...

Abstract

The invention relates to a vehicle brake control method and device, a storage medium and a vehicle. The method comprises the following steps: acquiring a brake signal of the vehicle; determining the expected brake strength according to the brake signal; if the expected brake strength is smaller than a preset strength threshold value, the vehicle speed is larger than a preset vehicle speed threshold value, and the SOC of a power battery is smaller than a preset charge threshold value, controlling the vehicle to be electrically braked; and if the expected brake strength is larger than or equal to the strength threshold value, the vehicle speed is larger than the vehicle speed threshold value, and the SOC of the power battery is smaller than the charge threshold value, controlling the vehicleto be subjected to electric brake and mechanical brake at the same time. Therefore, electric brake is preferential, the recovery rate of brake energy is increased, the new energy vehicle is more energy-saving, the use frequency of a mechanical braking system is reduced, and heat fade of a brake shoe is reduced.

Description

technical field [0001] The present disclosure relates to the field of vehicle control, and in particular, to a vehicle braking control method and device, a storage medium, and a vehicle. Background technique [0002] With the increasingly severe environmental problems, more and more users choose to use new energy vehicles. One of the energy-saving methods of new energy vehicles is that when the vehicle decelerates or brakes, energy can be recovered to charge and store the power battery to increase the driving range. Braking energy recovery is one of the important technologies of modern electric vehicles and hybrid vehicles, and it is also an important feature of them. In general internal combustion engine vehicles, when the vehicle decelerates and brakes, the kinetic energy of the vehicle is converted into heat energy through the braking system and released to the atmosphere. In electric vehicles and hybrid vehicles, this wasted motion energy can be converted into electric...
