The invention relates to the technical field of braking, and particularly discloses an auxiliary braking control method and device, a hybrid power vehicle and a storage medium. The method comprises the steps that the required auxiliary braking torque of hybrid power equipment, the allowable braking torque of a motor and the allowable braking torque of an engine are obtained; when the required auxiliary braking torque is larger than or equal to the motor allowable braking torque, the braking torque of a motor braking system is controlled to be gradually increased to the motor allowable braking torque; the total auxiliary braking torque of the hybrid power equipment is kept constant to be equal to the allowable braking torque of the motor, the braking torque of the engine braking system is controlled to be gradually increased, and the braking torque of the motor braking system is controlled to be gradually reduced until the engine braking system completely intervenes in braking; after the engine braking system completely intervenes in braking, the braking torque of the motor braking system is controlled to be gradually increased until the total auxiliary braking torque is equal to the required auxiliary braking torque, braking impact can be reduced, and braking of the hybrid power equipment is more stable.

    本发明涉及制动技术领域,具体公开了一种辅助制动控制方法、装置、混合动力车辆及存储介质,该方法包括:获取混合动力设备的需求辅助制动力矩、电机许用制动力矩和发动机许用制动力矩;当需求辅助制动力矩大于或等于电机许用制动力矩时,控制电机制动系统的制动力矩逐渐增大至电机许用制动力矩;保持混合动力设备的总辅助制动力矩等于电机许用制动力矩恒定,控制发动机制动系统的制动力矩逐渐增大,且控制电机制动系统的制动力矩逐渐减小,直至发动机制动系统完全介入制动;当发动机制动系统完全介入制动之后,控制电机制动系统的制动力矩逐渐增大,直至总辅助制动力矩等于需求辅助制动力矩,可减少制动冲击,使混合动力设备制动更加平稳。
