Abstract

A parking assistance system for a motor vehicle includes a monitoring unit for detecting an object in the vicinity of the vehicle and a light system connected to the monitoring unit and configured to emit light into the area surrounding the motor vehicle. The monitoring unit is configured to sense the bearing of an object and to control the distribution of the light emitted from the light system as a function of the sensed bearing.

First claim

What is claimed is:

1. A parking assistance system for a motor vehicle comprising:
a monitoring unit configured to detect an object in a zone surrounding the motor vehicle and to sense a bearing of the detected object; and
a lighting system operably coupled to the monitoring unit and configured to emit light in an area surrounding the motor vehicle;
wherein the monitoring unit controls a distribution of the emitted light as a function of the sensed bearing,
wherein the monitoring unit is further configured to determine when the detected object is on a left-side of the vehicle or on a right-side of the vehicle, and to produce a first distribution of emitted light when no object is detected, a second distribution of emitted light when the detected object is on the left-side of the motor vehicle and a third distribution of emitted light when the detected object is on the right-side of the motor vehicle,
wherein the lighting system comprises a first light located on the left-side of the motor vehicle and a second lights located on the right-side of the motor vehicle opposite the first light, the first and second lights being operable in a first operating state and a second operating state different from the first operating state; and wherein the monitoring unit is further configured to operate the first and second lights in the first operating state for producing the first distribution, to operate the first light in the first operating state and the second light in the second operating state for producing the second distribution, and to operate the first light in the second operating state and the second light in the first operating state for producing the second distribution,
wherein the monitoring unit is further configured to sense the distance of the detected object from the vehicle and to control a light property of the lighting system in the second operating state as a function of the sensed distance, and
wherein the controlled light property comprises an opening angle defined between a light boundary and a dark boundary of the light emitted by the first and second lights in the second operating state.

2. The parking assistance system according to claim 1 , wherein the lighting system is further configured to emit light in a direction of the detected object.

3. The parking assistance system according to claim 1 , wherein the first and second lights comprise a pair of lights selected from the group consisting of indicator lights or headlights.

4. The parking assistance system according to claim 1 , wherein the controlled light property is selected from the group consisting of a light intensity, a light color, a spatial light distribution, a temporal light distribution or a combination thereof.

5. The parking assistance system according to claim 1 , wherein the lighting system is operable in a third operating state and the orientation of the light boundary and the dark boundary is different in the second operating state and the third operating state.

6. The parking assistance system according to claim 1 , wherein the monitoring unit is further configured to determine when the detected object is ahead of the motor vehicle in a direction of travel and to produce a fourth distribution of light when the detected object is ahead of the vehicle.

7. The parking assistance system according to claim 6 , wherein the monitoring unit is configured to produce the fourth distribution of light through operating the first and second lights in the second operating state.

8. The parking assistance system according to claim 6 , wherein the lighting system is operable in a third operating state and the monitoring unit is configured to produce the fourth distribution of light through operating both lights in the third operating state.

9. A method of assisting the parking of a motor vehicle comprising:
detecting an object in a zone surrounding the motor vehicle;
sensing a bearing of the detected object;
emitting light in an area surrounding the motor vehicle;
controlling a distribution of the emitted light as a function of the sensed bearing;
sensing a distance of the detected object from the motor vehicle; and
controlling a light property of the light as a function of the sensed distance, and
wherein the controlled light property comprises an opening angle defined between a light boundary and a dark boundary of the emitted light.

10. The method according to claim 9 , wherein emitting light in an area surrounding the motor vehicle comprises emitting light in a direction of the detected object.

11. A non-transitory computer-readable medium comprising program instructions, which when executed on a computer, perform:
detecting an object in a zone surrounding the motor vehicle;
sensing a bearing of the detected object;
emitting light in an area surrounding the motor vehicle;
controlling a distribution of the emitted light as a function of the sensed bearing;
sensing a distance of the detected object from the motor vehicle; and
controlling a light property of the light as a function of the sensed distance, and
wherein the controlled light property comprises an opening angle defined between a light boundary and a dark boundary of the emitted light.
