The invention discloses a hybrid vehicle brake control method and a hybrid vehicle. The hybrid vehicle brake control method comprises the steps that whether a brake pedal is treaded or not is monitored in real time; if it is monitored that the brake pedal is treaded, the braking mode of the vehicle is determined according to the opening degree of the brake pedal and the opening degree change rate of the brake pedal; the first braking mode is motor braking, the second braking mode is motor braking and engine in-cylinder braking, and the third braking mode is motor full-power braking and engine full-power braking; the total braking demand torque is determined according to the opening degree of a brake pedal and the load of the vehicle; engine braking demand torque and/or motor braking demand torque are/is determined according to the total braking demand torque and the braking mode of the vehicle; controlling the motor to output a motor braking demand torque; and/or controlling the engine to output the engine braking demand torque. The braking performance of the power assembly system of the hybrid electric vehicle can be fully exerted, the braking performance of the hybrid electric vehicle is improved, and the cost of the hybrid electric vehicle is reduced.
本发明公开了混合动力车制动控制方法及混合动力车,该混合动力车制动控制方法:实时监测是否踩踏刹车踏板;若监测到踩踏刹车踏板,则依据刹车踏板的开度和刹车踏板的开度变化率确定车辆的制动模式;第一制动模式为电机制动,第二制动模式为电机制动和发动机缸内制动,第三制动模式为电机全功率制动和发动机全功率制动;依据刹车踏板的开度和车辆的载重确定总制动需求扭矩;依据总制动需求扭矩和车辆的制动模式确定发动机制动需求扭矩和/或电机制动需求扭矩;控制电机输出电机制动需求扭矩;和/或,控制发动机输出发动机制动需求扭矩。能充分发挥混合动力车的动力总成系统本身的制动性能,提升了混合动力车的制动性能,降低了混合动力车的成本。
