The invention discloses a brake torque control method of a hybrid power vehicle and the hybrid power vehicle, and relates to the technical field of hybrid power vehicles. The control method for the braking torque of the hybrid power vehicle comprises a control method for automatically controlling the braking torque. The control method for automatically controlling the braking torque comprises the following steps that the maximum power, allowing motor energy recovery currently, of the vehicle is calculated; setting a required target acceleration according to the opening degree of the current brake pedal, wherein the target acceleration is smaller than zero; whether the maximum power, allowing motor energy recovery currently, of the vehicle can make the acceleration of the vehicle reach the target acceleration or not is judged; if yes, motor braking is kept until the acceleration of the vehicle reaches the target acceleration; and if not, motor braking and engine auxiliary braking are controlled to be jointly braked. Motor braking or motor braking and engine auxiliary braking are automatically controlled according to the actual working condition, and the safety of vehicle braking under the ramp working condition is effectively improved; and the cost is low.

    本发明公开了一种混合动力车辆的制动扭矩的控制方法及混合动力车辆,涉及混合动力车辆技术领域。混合动力车辆的制动扭矩的控制方法包括自动控制制动扭矩的控制方法,自动控制制动扭矩的控制方法包括以下步骤:计算车辆当前允许电机能量回收的最大功率;根据当前制动踏板的开度设定需求的目标加速度,目标加速度小于零;判断车辆当前允许电机能量回收的最大功率是否能使车辆的加速度达到目标加速度;若是,则保持电机制动直至车辆的加速度达到目标加速度;若否,则控制电机制动和发动机辅助制动共同制动。实现了根据实际工况自动控制电机制动或电机制动和发动机辅助制动共同制动,有效提高坡道工况下车辆制动的安全性;而且成本较低。
