Abstract

A vehicle parking aid system may employ a seat, a steering wheel, and at least one or more sensors disposed about the periphery of the vehicle to detect objects outside of the vehicle. Additionally, indicators, which may be vibratory, may be disposed in a component such as a seat and/or the steering wheel of the vehicle and are associated with the sensor(s). The vehicle component may communicate with a driver of the vehicle via the at least one indicator, which may vibrate when the at least one sensor detects an object near the vehicle and sensor. The indicators may be selectively orientated in the seat and steering wheel and activated by the sensors in a manner that indicates a location of the detected object relative to the vehicle.

Claims

1. A parking aid system for a vehicle having a seat and a steering wheel, the parking aid system comprising:

at least one sensor disposed on the vehicle and operable to detect an object around a periphery of the vehicle; and

at least one indicator disposed in a component of the vehicle and associated with the at least one sensor, the component communicating with a driver of the vehicle, the at least one indicator operable to vibrate when the at least one sensor detects the object near the vehicle.

2. The parking aid system of claim 1, wherein the at least one indicator is disposed in the steering wheel of the vehicle.

3. The parking aid system of claim 2, wherein the at least one sensor is a plurality of sensors and one sensor is disposed generally at each corner of the vehicle.

4. The parking aid system of claim 1, wherein the at least one indicator is a plurality of indicators peripherally disposed around the steering wheel.

5. The parking aid system of claim 1, wherein the at least one indicator is disposed in the seat of the vehicle.

6. The parking aid system of claim 5, wherein the at least one sensor includes one sensor disposed generally at each corner of the vehicle and the at least one indicator is disposed in a seat bottom cushion.

7. The parking aid system of claim 6, wherein the at least one indicator is a plurality of indicators disposed in a generally rectangular pattern in the seat bottom cushion and each of indicators is associated with a sensor disposed in a respective corner of the vehicle.

8. The parking aid system of claim 1, wherein the at least one sensor is a plurality of sensors disposed around the periphery of the vehicle, the sensors spaced apart to detect objects on different sides of the vehicle.

9. The parking aid system of claim 8, wherein the at least one indicator is a plurality of indicators spaced apart in the component of the vehicle, each of the indicators selectively operable to vibrate.

10. The parking aid system of claim 9, wherein each of the plurality of indicators is associated with a general position of the detected object.

11. A parking aid system for a vehicle having a steering wheel, the parking aid system comprising:

a control unit;

a plurality of first sensors on the vehicle and communicating with the electronic control unit, each of the first sensors operable to detect an object near the vehicle and send a first input signal to the electronic control unit when the object is detected; and

a plurality of indicators disposed around a periphery of the steering wheel, each of the indicators selectively operable to vibrate when activated by the control unit; and

a second sensor disposed in the steering wheel and communicating with the electronic control unit, the second sensor operable to detect a gripping force and send a second input signal to the electronic control unit when the gripping force is detected,

wherein the electronic control unit is operable to receive the first and second input signals, determine a peripheral position of a hand of the driver on the steering wheel based on the second input signal, and selectively activate the indicators proximate to the peripheral position of the hand when the first sensor detects the object.

12. The parking aid system of claim 11, wherein the second sensor is operable to detect a temperature and send the second input signal to the electronic control unit when the temperature is detected.

13. The parking aid system of claim 11, wherein the second sensor is a plurality of force sensors spaced around a cross-section of the steering wheel.

14. A method of communicating a location of an object detected near a vehicle to a driver of the vehicle, the method comprising the steps of:

(a) providing a plurality of object detection sensors proximate a periphery of the vehicle;

(b) providing a plurality of indicators in a component of the vehicle, the component in contact with the driver, the indicators spaced apart in the component such that the driver can determine a relative position of the indicators when the indicators are activated;

(c) detecting an object with one of the sensors; and

(d) activating the indicators to communicate a location of the object detected by the one of the sensors to the driver, the location based on the relative position of the activated indicators.

15. The method of claim 14, wherein step (b) includes providing the indicators in a steering wheel of the vehicle.

16. The method of claim 15, wherein step (d) includes determining a position of a hand of the driver on the steering wheel relative to the indicators and activating the indicators proximate to the position of the hand to indicate the location of the object detected by the one of the sensors.

17. The method of claim 16, wherein determining the position of the hand includes distinguishing a right hand from a left hand and determining the position of each of the right and left hands on the steering wheel.

18. The method of claim 17, wherein distinguishing the right hand from the left hand includes identifying a gripping pattern of at least one of the right hand and the left hand based on relative positions of a palm, a thumb, and fingers of the hand.

19. The method of claim 14, wherein step (b) includes providing position indicators in a seat of the vehicle.

20. The method of claim 14, wherein step (a) includes disposing one of the sensors in each corner of the vehicle.
