The invention relates to the technical field of vehicle braking, in particular to a combined braking method and device of service braking and auxiliary braking in an engine cylinder. The method comprises the steps that for a target whole vehicle, the running speed, the engine rotating speed, the accelerator opening degree and the brake pedal state of the target whole vehicle are obtained; and according to preset conditions met by the running speed of the target whole vehicle, the rotating speed of an engine, the opening degree of an accelerator and the state of a brake pedal, determining to open or close auxiliary braking in an engine cylinder so as to enter or exit a combined braking state. According to the invention, a combined braking mode of traveling braking and auxiliary braking in the engine cylinder can be automatically entered, good braking performance of the whole vehicle is ensured, and the problems of braking capacity reduction or tire burst caused by frequent and long-time traveling braking of the whole vehicle can be reduced.

    本申请涉及车辆制动技术领域,更为具体来说,本申请涉及行车制动与发动机缸内辅助制动的联合制动方法与装置。所述方法包括:针对目标整车,获取所述目标整车的行车速度、发动机转速、油门开度、制动踏板状态;根据所述目标整车的行车速度、发动机转速、油门开度、制动踏板状态所满足的预设条件确定开启或关闭发动机缸内辅助制动,以进入或退出联合制动状态。本申请能实现自动进入行车制动、发动机缸内辅助制动的联合制动模式,确保整车良好的制动性能,且能够减少整车频繁、长时采用行车制动刹车所带来的制动能力下降或爆胎问题的发生。
