Method and device for warning the driver of a motor vehicle
First Claim
1. A method for warning a driver of a motor vehicle, comprising:
- detecting, by an object detector, at least one preceding vehicle, and a distance and relative velocity with respect to the motor vehicle;
supplying the distance and relative velocity to an evaluation device;
ascertaining, by the evaluation device, whether, assuming that the preceding vehicle initiated a deceleration, a collision with the preceding vehicle would be avoidable as a function of a reaction time of the driver and a maximum possible deceleration of the motor vehicle; and
activating a warning device in an event that the collision would be unavoidable.

Abstract
A method and a device for warning the driver of a motor vehicle. An object detector is provided, which detects preceding vehicles and ascertains their distance and relative velocity with respect to the host vehicle and supplies these to an evaluation device. The evaluation device assumes that the preceding vehicle would perform a deceleration and ascertains as a further function of the variables measured by the object detector and the driver'"'"'s reaction time and the host vehicle'"'"'s maximum possible deceleration whether a collision with the preceding vehicle would be avoidable. If an unavoidability of a collision is recognized, then a driver warning device is activated.

9. A device for warning a driver of a motor vehicle, comprising:
-
an object detector which detects a preceding vehicle and a distance and relative velocity with respect to the motor vehicle; an evaluation device which receives the distance and the relative velocity, the evaluation device configured to ascertain whether, assuming that the preceding vehicle initiated a deceleration, a collision with the preceding vehicle would be avoidable as a function of a reaction time of the driver and of a maximum possible deceleration of the motor vehicle; and a driver warning device configured to issue a driver warning in an event that a collision is unavoidable. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
