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 present disclosure relates to a vehicle braking control method and device, a storage medium, and a vehicle. The method includes: acquiring the braking signal of the vehicle; determining the expected braking strength according to the braking signal; if the expected braking strength is less than a predetermined strength threshold, the vehicle speed is greater than the predetermined vehicle speed threshold, and the power battery If the SOC is less than a predetermined charging threshold, control the electric braking of the vehicle; if the desired braking strength is greater than or equal to the strength threshold, the vehicle speed is greater than the vehicle speed threshold, and the SOC of the power battery is less than the predetermined If the charging threshold is exceeded, the vehicle is controlled to perform electric braking and mechanical braking at the same time. This gives priority to electric braking, thereby improving the recovery rate of braking energy, making new energy vehicles more energy-efficient, and reducing the frequency of use of the mechanical braking system and reducing the thermal degradation of the brake shoes.

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...
