Abstract
A method and a device for warning the driver of a motor vehicle about a traffic situation involving an increased collision risk are provided. For this purpose, signals of at least one object detector representing motion quantities of detected objects and signals of at least one motion sensor system of the host vehicle are suppliable to an analyzer device. The computing device precalculates all possible motion trajectories for all detected objects and for the host vehicle, taking into account maximum acceleration or deceleration values and maximum change in acceleration or deceleration values over time and, when an imminent collision is recognized, issues a warning to the driver that higher acceleration or deceleration values and/or change in acceleration or deceleration values are needed to avoid a collision.

10. A method for warning a driver of a motor vehicle of a traffic situation involving an increased collision risk, comprising:
-
supplying signals from at least one object detector to an analyzer device, wherein the signals represent motion quantities of at least one detected object;
supplying signals from at least one motion sensor system to the analyzer device, wherein the signals represent motion quantities of the motor vehicle;
calculating by the analyzer device all possible motion trajectories for each detected object and for the motor vehicle, taking into account;
a) one of maximum acceleration value and maximum deceleration value; and
b) one of maximum change in acceleration value over time and maximum change in deceleration value over time; and
issuing a warning to the driver, when an imminent collision is recognized based on the calculating by the analyzer device, wherein the warning includes an indication that at least one of the following is needed to avoid a collision;
a) higher acceleration value;
b) higher deceleration value;
c) a higher change in acceleration value over time; and
d) a higher change in deceleration value over time. - View Dependent Claims (11, 12, 13, 14, 15)
