Method and device for avoiding a collision in a lane change maneuver of a vehicle
First Claim
1. A method for avoiding a collision in a lane change maneuver of a vehicle from an instantaneous lane to a target lane, the method comprising:
- detecting objects in a lateral rearward space of the vehicle; and
taking measures are to influence the vehicle, wherein the measures, depending on their stage, involve at least one of warning a driver, intervening into a steering system of the vehicle, and influencing a safety device, and measures of a selected stage are initiated, with the stage being determined depending on at least one of a relative position of a detected object (4) with regard to the vehicle (1) and a relative speed between the vehicle (1) and the detected object (4) as well as depending on fulfillment of a lane change condition, and wherein a steering torque that is invariable in terms of direction is applied to a steering handle in order to return the vehicle (1) completely into the instantaneous lane or to keep it in the lane when, on account of a lane change to the target lane, the longitudinal distance between the vehicle (1) and the object (4) detected within the target lane would become shorter than a predetermined minimum distance, when a second lane change condition is satisfied, and when the danger potential exceeds a first threshold value.

Abstract
Disclosed is a method for avoiding a collision in a lane change maneuver of a vehicle to a target lane, where objects in a lateral rearward space of the vehicle are detected by an ambience monitoring device and measures are taken to influence the vehicle. The method is characterized in that graded measures are provided that depending on their stage, involve warning the driver and/or intervening into a steering system of the vehicle and/or influencing safety devices. The measures of a selected stage are initiated, with the stage being determined depending on a relative position of a detected object with regard to the vehicle and/or a relative speed between the vehicle and the detected object as well as depending on the fulfillment of a lane change condition. Also disclosed is a device that is well suited to implement the method.

28. A device for avoiding a collision in a lane change maneuver of a vehicle to a target lane, the device comprising:
-
an ambience monitoring device that is used to sense objects in a rearward space of the vehicle; a danger computer that initiates graded measures to influence the vehicle (1), with the graded measures, corresponding to a respective stages, including at least one of warning a driver, intervening into a steering system of the vehicle (1), and influencing a safety element, wherein the danger computer initiates measures of a stage, which can be determined depending on at least one of a relative position of a detected object (4) with regard to the vehicle (1) or a relative speed between the vehicle (1) and the detected object (4), and also depends on a fulfillment of a lane change condition, and wherein a steering torque that is invariable in terms of direction is applied to a steering handle in order to return the vehicle (1) completely into the instantaneous lane or to keep it in the lane when, on account of a lane change to the target lane, the longitudinal distance between the vehicle (1) and the object (4) detected within the target lane would become shorter than a predetermined minimum distance, when a second lane change condition is satisfied, and when the danger potential exceeds a first threshold value. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
