Abstract

A method is provided for monitoring a starting maneuver of a motor that includes, but is not limited to determining whether an object is detected by a first sensor of the motor vehicle. The first sensor is preferably an ultrasonic sensor that detects objects within a first detection area. The first detection area includes, but is not limited to a first sub-area of surroundings of the motor vehicle that lies in a driving direction. If an object is detected by the the first sensor, the degree of probability of a collision between the object detected by the first sensor and the motor vehicle in case of a starting maneuver of the motor vehicle is determined. If the determined degree of collision probability exceeds a first predefined threshold value, the starting maneuver of the motor vehicle is at least temporarily interrupted.

Claims

determining whether at least one object is detected by at least one first sensor,

wherein the at least one first sensor is realized in a form of an ultrasonic sensor for detecting objects within a first detection area, and

determining a degree of probability of a collision between the at least one object detected by the at least one first sensor and the motor vehicle in case of the starting maneuver of the motor vehicle if the at least one object is detected by the at least one first sensor; and

at least temporarily interrupting the starting maneuver of the motor vehicle if the degree of probability of the collision exceeds a first predefined threshold value.

2. The method according to claim 1, further comprising generating a warning message if the degree of probability of the collision exceeds the first predefined threshold value.

3. The method according to claim 2, wherein the warning message is an optical warning message.

4. The method according to claim 1, further comprising:

determining whether the at least one object is detected by at least one second sensor of the motor vehicle,

wherein the at least one second sensor is realized in the form of an electromagnetic sensor for detecting objects within a second detection area, and

wherein the second detection area comprises a second sub-area of the surroundings of the motor vehicle that lies in the driving direction of the motor vehicle to be monitored and at least partially differs from the first detection area;

determining the degree of probability of the collision between the at least one object detected by the at least one second sensor and the motor vehicle in case of the starting maneuver of the motor vehicle if the at least one object is detected by the at least one second sensor; and

at least temporarily interrupting the starting maneuver of the motor vehicle if the degree of probability of the collision exceeds a second predefined threshold value.

5. The method according to claim 4, wherein the determining whether the at least one object is detected by the at least one second sensor is performed prior to determining whether the at least one object is detected by the at least one first sensor.

6. The method according to claim 5, wherein it is determined whether the at least one object is detected by the at least one first sensor of the motor vehicle if no object is detected by the at least one second sensor or if the degree of probability of the collision does not exceed the second predefined threshold value.

7. The method according to one of claim 4, wherein the at least one second sensor is a lidar sensor.

8. The method according to claim 1, wherein the at least temporarily interrupting the starting maneuver is configured for cancellation by an occupant of the motor vehicle.

9. The method according to claim 7, wherein the at least temporarily interrupting the starting maneuver is configured for cancellation by actuating an control element of the motor vehicle.

10. The method according to claim 1,

wherein the motor vehicle comprises an adaptive cruise control system, and

wherein the determining whether the at least one object is detected by the at least one first sensor of the motor vehicle is conducted at least after a deceleration of the motor vehicle to a standstill with the adaptive cruise control system.

11. The method according to claim 10, further comprising resuming control of a trailing distance from another motor vehicle that was determined as target vehicle for control of the trailing distance prior to the deceleration after a restarting maneuver.

12. The method according to claim 10, further comprising adjusting a speed of the motor vehicle to a predefined speed with the adaptive cruise control system after a restarting maneuver.
