The invention provides a whole vehicle braking control method and system and an automobile. When it is determined that whole vehicle braking needs to be conducted through an acquisition module, braking parameters of a braking loop on the automobile are acquired and sent to a braking electric control module; when the braking electronic control module determines that at least one braking loop on the automobile has a braking fault according to the braking parameters, the braking electronic control module controls and reduces the output torque of a driving motor of the automobile so as to control the automobile to decelerate, and when the braking loop has the braking fault, the braking electronic control module actively controls and reduces the output torque of the driving motor to realize deceleration braking of the automobile. The problem that in an existing scheme, safety braking cannot be effectively achieved for automobile deceleration due to brake circuit faults is solved.

本申请提供一种整车制动控制方法、系统及汽车，通过采集模块在确定需要进行整车制动时，采集汽车上制动回路的制动参数，并将制动参数发送给制动电控模块，制动电控模块在根据制动参数确定汽车上的至少一个制动回路存在制动故障时，控制降低汽车的驱动电机的输出扭矩以控制汽车减速，通过在制动回路存在制动故障时，主动控制降低驱动电机的输出扭矩实现汽车的减速制动，解决了现有方案中因制动回路故障无法有效对汽车减速实现安全制动的问题。
