The invention discloses an anti-collision brake control method and a brake control system, and relates to the technical field of vehicle control, the brake control method comprises the following steps: obtaining an actual distance S0 and a relative speed V0; meanwhile, a predicted braking distance S1 is obtained according to the relative speed V0, the maximum deceleration a0 and known braking system response time; and S1, S0 and kS1 are compared, when S1 < = S0 < = kS1 and V0 > = 0, yellow early warning is given out, meanwhile, the state of a brake pedal is monitored, and when the brake pedal is in a released state, a brake system provides additional deceleration until the distance between the vehicle and a front obstacle is larger than kS1, yellow early warning and monitoring of the brake pedal are relieved. According to the braking control method and the braking control system, early warning and control can be conducted in advance before the vehicle possibly enters the collision risk area, the road adhesion coefficient is considered, and the problems that in the prior art, the comfort is poor during braking, and the front collision risk is large when the road adhesion coefficient is low are solved.

    本申请公开了一种防碰撞的制动控制方法及制动控制系统,涉及车辆控制技术领域,制动控制方法包括步骤:获取实际距离S0和相对速度V0;同时,根据相对速度V0、最大减速度a0、及已知的制动系统响应时间获取预测制动距离S1;比对S1、S0和kS1,在S1≤S0≤kS1且V0≥0时,发出黄色预警,同时监控制动踏板状态,并在制动踏板处于松开状态,制动系统提供额外减速度,直至车辆与前方障碍物间距大于kS1,解除黄色预警和制动踏板的监控。本申请的制动控制方法及制动控制系统,能够在车辆可能进入碰撞风险区域前提前预警并控制,并且考虑了路面附着系数,解决了现有技术中制动时舒适性差以及路面附着系数低时前碰风险大的问题。
