The invention relates to a vehicle safety control method and device, and the method comprises the steps: collecting vehicle information and obstacle information, and calculating the impending collision time of a vehicle and an obstacle; the time to be collided is judged, and if the time to be collided is smaller than or equal to a first set time threshold value and larger than a second set time threshold value, engine torque limiting and safety belt drawing early warning control are conducted; if the time to be collided is smaller than or equal to a second set time threshold value and larger than a third set time threshold value, first-stage braking control is carried out, and the first-stage braking control comprises the step of controlling a retarder to operate; and if the time to be collided is smaller than or equal to the third set time threshold value, second-stage braking control is conducted, and the second-stage braking control comprises control over safety belt pre-tightening or/and braking system operation. According to the invention, different safety systems on the vehicle are controlled to execute corresponding safety actions according to the time to be collided, so that the driving safety is ensured, and the driving safety of the vehicle is effectively improved.

    本发明涉及一种车辆安全控制方法及装置,包括:采集本车信息和障碍物信息,计算车辆与障碍物的即将碰撞时间;对即将碰撞时间进行判断,若即将碰撞时间小于等于第一设定时间阈值、且大于第二设定时间阈值,则进行发动机限扭及安全带抽动预警控制;若即将碰撞时间小于等于第二设定时间阈值、且大于第三设定时间阈值,则进行一级制动控制,一级制动控制包括控制缓速器运行;若即将碰撞时间小于等于第三设定时间阈值,则进行二级制动控制,二级制动控制包括控制安全带预紧或/和制动系统运行。本发明根据即将碰撞时间的大小,控制车辆上不同的安全系统执行相应的安全动作,以保证行车安全,有效提高了车辆行车安全性。
