Abstract

A method for controlling a vehicle, including determining a speed curve on a coasting route, in order to let the vehicle on the coasting route coast from an actual speed to a setpoint speed, detecting an additional vehicle approaching the vehicle from behind on the coasting route, and raising the speed of the vehicle compared to the determined speed behavior on the coasting route, in order to produce a predetermined threshold distance from the additional vehicle.

Claims

1. A method for controlling a vehicle, comprising:

determining a speed curve on a coasting route, to let the vehicle on the coasting route coast from an actual speed to a setpoint speed;

detecting an additional vehicle approaching the vehicle from behind on the coasting route; and

raising a speed of the vehicle compared to the determined speed behavior on the coasting route, to produce a predetermined threshold distance from the additional vehicle.

2. The method as recited in claim 1, wherein the raising includes raising the speed of the vehicle on the coasting route if a certain switch on the vehicle is activated.

3. The method as recited in claim 1, further comprising:

ending the raising of the speed of the vehicle if the vehicle falls below a predetermined safety distance from a preceding vehicle.

4. The method as recited in claim 1, comprising:

ending the raising of the speed of the vehicle if an admissible maximum speed has been reached.

5. The method as recited in claim 4, wherein the admissible maximum speed is a function of an admissible cornering speed.

6. The method as recited in claim 1, further comprising:

ending the raising of the speed of the vehicle of the vehicle if a passing process of the additional vehicle approaching from behind has been detected.

7. The method as recited in claim 1, further comprising:

determining a minimum braking distance to a position at which the setpoint speed is supposed to be reached; and

ending the raising of the speed of the vehicle if the minimum braking distance to the position at which the setpoint speed is to be reached, has been reached.

8. The method as recited in claim 7, further comprising:

indicating a necessary braking process if the minimum braking distance to the position, at which the setpoint speed is to be reached, has been reached.

9. A control device to control a vehicle, the control to determine a speed curve on a coasting route, to let the vehicle on the coasting route coast from an actual speed to a setpoint speed, to detect an additional vehicle approaching the vehicle from behind on the coasting route, and to raise a speed of the vehicle compared to the determined speed behavior on the coasting route, to produce a predetermined threshold distance from the additional vehicle.
