    • A collision warning system and method for a motor vehicle. A measuring device in the vehicle is provided for measuring the distance dx to a second vehicle traveling ahead, the distance signal being delivered to an evaluation device in the first vehicle. The evaluation device continuously calculates a deceleration asubject vehicle demand, which is applied by the vehicle after expiration of a driver reaction time Treaction in order that a remaining distance dxremaining to the second vehicle traveling ahead can be maintained. If asubject vehicle demand exceeds an instantaneous deceleration that can be achieved by an adaptive cruise control (“ACC”) system, a system limit warning is transmitted, prompting the vehicle driver to brake with additional appropriate force. If asubject vehicle demand exceeds an assumed vehicle deceleration that can be generated by braking on the part of the driver, a collision warning signal is transmitted independently of the ACC system.
    • 一种机动车辆的碰撞预警系统和方法。 提供车辆中的测量装置,用于测量与向前行驶的第二车辆的距离dx,该距离信号被传送到第一车辆中的评估装置。 评估装置连续地计算在驾驶员反应时间T<<<>之后由车辆施加的本车辆需求的减速度,以便剩余距离dx 。 如果主体车辆需求超过可通过自适应巡航控制(“ACC”)系统实现的瞬时减速度,则发送系统限位警告,提示车辆驾驶员以额外的适当力量制动。 如果主体车辆需求超过可以通过驾驶员的部分制动而产生的假定车辆减速度,则独立于ACC系统发送碰撞警告信号。
