Dynamic forward collision alert system

A method of providing a collision warning within a vehicle comprises detecting an object and determining the distance to the object, identifying when a driver is distracted and measuring the time thatthe driver has been distracted, calculating an actual time to collision, modifying first and second pre-determined time to collision thresholds based on information from the driver monitoring systemand creating first and second modified time to collision thresholds, comparing the actual time to collision to the first and second modified time to collision thresholds, sending a signal to a driverinterface to provide an initial warning to the driver when the actual time to collision is less than the first modified time to collision threshold, and sending a signal to the driver interface to provide an imminent collision warning to the driver when the actual time to collision is less than the second modified time to collision threshold. 一种在车辆内发出碰撞预警的方法包括：检测物体并确定到物体的距离；确认驾驶员何时分心并测量驾驶员已经分心的时间；计算出实际避撞时间；根据来自驾驶员监视系统的信息来修改
