Braking control method and system, vehicle, storage medium and chip

A braking control system, wherein the braking control system is arranged in a vehicle, the vehicle is a four-wheeled vehicle, the braking control system comprises:

• a central control unit;
• rim braking units;
• braking motors;
• a front axle motor;
• and
• a first rear axle motor corresponding to a left rear wheel and a second rear axle motor corresponding to a right rear wheel, wherein
• two front wheels of the vehicle are each correspondingly provided with one of the rim braking units and one or the braking motors, each of the rim braking units is configured to receive a control instruction from the central control unit to control a respective braking motor corresponding a respective rim breaking unit that receives the control instruction,
• the central control unit is configured to adjust, in response to a braking state update instruction, at least one braking state of at least one of the braking motors or a target drive motor according to the braking state update instruction,
• the target drive motor comprises at least one of:
• the front axle motor, the first rear axle motor or the second rear axle motor, and
• the braking state update instruction comprises at least one of:
• a braking instruction, a vehicle tracking control triggering instruction, or a vehicle dynamic control triggering instruction;
• wherein adjust, in response to the braking state update instruction, the at least one braking state according to the braking state update instruction comprises:
• in response to the braking instruction, in a case where a required braking force to which the braking instruction corresponds is determined to be greater than a preset threshold, control two braking motors to which the two front wheels respectively correspond to generate braking forces to satisfy the required braking force;
• and
• in a case where braking forces generated by the two braking motors fail to satisfy the required braking force, control the first rear axle motor and/or the second rear axle motor to generate a negative torque to achieve the required braking force.

A vehicle, comprising:

• a processor;
• and
• a memory for storing processor-executable instructions,
• wherein the processor is configured to adjust, in response to a braking state update instruction, at least one braking state of at least one of a braking motor or a target drive motor according to the braking state update instruction,
• wherein the target drive motor comprises at least one of:
• a front axle motor, a first rear axle motor or a second rear axle motor, and
• the braking state update instruction comprises at least one of:
• a braking instruction, a vehicle tracking control triggering instruction, or a vehicle dynamic control triggering instruction;
• wherein adjust, in response to the braking state update instruction, the at least one braking state according to the braking state update instruction comprises:
• in response to the braking instruction, in a case where a required braking force to which the braking instruction corresponds is determined to be greater than a preset threshold, control two braking motors to which the two front wheels respectively correspond to generate braking forces to satisfy the required braking force;
• and
• in a case where braking forces generated by the two braking motors fail to satisfy the required braking force, control the first rear axle motor and/or the second rear axle motor to generate a negative torque to achieve the required braking force.
