The invention discloses a vehicle emergency braking method and device, equipment and a medium, and relates to the technical field of automatic driving, and the method comprises the following steps: obtaining control information under different vehicle operation information in a current road type; the control information comprises an accelerator pedal opening degree, a brake pedal opening degree, a steering wheel angle and a steering wheel angle rate, and the vehicle running information comprises a vehicle speed and a vehicle acceleration; determining lane departure assistance times and lane departure early warning times in the target driving time; dividing the control information, the lane departure assistance times and the lane departure early warning times into an attention concentration degree grade interval to obtain a division result; and adjusting the triggering time of the automatic emergency braking system according to the division result and an adjustment strategy determined based on the collision time threshold. Therefore, the intervention time of emergency braking is adjusted based on the attention concentration degree and the driving habit of the driver, and the hardware improvement cost is greatly reduced.
本申请公开了一种车辆紧急制动方法、装置、设备及介质,涉及自动驾驶技术领域,包括:获取当前道路类型中不同车辆运行信息下的操控信息;操控信息包括油门踏板开度、制动踏板开度、方向盘转角与方向盘转角速率,车辆运行信息包括车辆速度与车辆加速度;确定目标驾驶时间内的车道偏离辅助次数与车道偏离预警次数;将操控信息、车道偏离辅助次数与车道偏离预警次数划分至注意力集中程度等级区间,得到划分结果;根据划分结果与基于碰撞时间阈值确定的调整策略对自动紧急制动系统的触发时间进行调整。可见,本申请基于驾驶员的注意力集中程度与驾驶习惯对紧急制动的介入时间进行调整,并大大降低了硬件改进成本。
