The invention discloses a vehicle braking method and system, and relates to the technical field of vehicle braking. According to the method, EMB is integrated into vehicle braking, and a braking request is sent out according to the vehicle driving state; when the EMB receives a service braking request, the braking force required by the current wheel is distributed according to the current motion parameter and the target motion parameter of the vehicle, and the braking deceleration and deceleration request required by the corresponding wheel is generated; the driving circuit is controlled to operate according to the braking deceleration and deceleration request required by the wheel so as to drive the executing mechanism to apply clamping force to a wheel brake disc for friction braking, and therefore the service braking effect is achieved; when a parking braking request is received, a target clamping force value is obtained, then clamping force is still applied to a wheel brake disc through an executing mechanism, the current clamping force value is compared with the target clamping force value, and after the current clamping force value is larger than the target clamping force value, the executing mechanism is locked to complete parking. Finally, a brake system is simplified, brake pipelines and elements of a hydraulic system are omitted, and manufacturing cost is reduced.
本发明公开了一种车辆制动方法及制动系统,涉及车辆制动技术领域。其通过将EMB融入车辆制动,依据车辆行驶状态发出制动请求;当EMB接收行车制动请求,依据车辆当前运动参数及目标运动参数分配当前车轮所需制动力并生成对应车轮所需制动减速度与减速请求,再依据车轮所需制动减速度与减速请求控制驱动电路运行以驱动执行机构对车轮制动盘施加夹紧力摩擦制动,从而实现行车制动的效果;接收驻车制动请求时,然后获取目标夹紧力值,接着仍通过执行机构对车轮制动盘施加夹紧力,并比较当前夹紧力值与目标夹紧力值,直至当前夹紧力值大于目标夹紧力值后,锁定执行机构以完成驻车;最终简化了制动系统,取消了液压系统的制动管路及元件,降低了制造成本。
