Abstract

A vehicle is provided, including a vehicle body; at least one vehicle element pivotally mounted to the vehicle, the vehicle element configured to pivot through an angle not more than 360 degrees; and a measuring arrangement configured to measure an angular velocity of the at least one vehicle element.

Claims

1. A vehicle, comprising:

a vehicle body;

at least one vehicle element pivotally mounted to the vehicle body, the vehicle element configured to pivot through an angle not more than 360 degrees; and

a measuring arrangement configured to measure an angular velocity of the vehicle element.

2. The vehicle according to claim 1, wherein the at least one vehicle element includes at least one of a vehicle door, a lift-gate, a trunk, a hood, a seat-back, a tilt-wheel, and a glove compartment.

3. The vehicle according to claim 1, wherein the measuring arrangement is configured to measure the angular velocity during at least one of an opening and a closing of the at least one vehicle element.

4. The vehicle according to claim 1, wherein the measuring arrangement includes an angular velocity encoder electrically connected to a frequency converter, the angular velocity encoder providing a signal to the frequency converter in accordance with the angular velocity of the at least one vehicle element, the frequency converter generating an analog output in accordance with a characteristic of the signal.

5. The vehicle according to claim 4, wherein the signal includes a pulse train.

6. The vehicle according to claim 5, wherein the characteristic includes at least one of a pulse width and a period of the pulse train.

7. The vehicle according to claim 1, wherein the measuring arrangement includes a piezoelectric gyroscope rate sensor configured to produce an analog output in accordance with the angular velocity of the at least one vehicle element.

8. The vehicle according to claim 1, further comprising:

at least one vehicle system;

wherein the measuring arrangement is configured to communicate angular velocity information to the at least one vehicle system in accordance with the angular velocity of the at least one vehicle element.

9. The vehicle according to claim 8, wherein the at least one vehicle system includes a storage unit configured to store at least a portion of the angular velocity information.

10. The vehicle according to claim 9, wherein the storage unit includes at least one of a RAM, a hard disk, a flash memory, an EPROM, an EEPROM, and a mini-disk.

11. The vehicle according to claim 9, wherein the at least one vehicle system further includes a peak detecting arrangement configured to detect a peak angular velocity of the angular velocity information.

12. The vehicle according to claim 11, wherein the peak detecting arrangement is configured to communicate the peak angular velocity to the storage unit, the storage unit being configured to store the peak angular velocity.

13. The vehicle according to claim 9, wherein the at least one vehicle system includes a user interface arrangement configured to communicate the portion of the angular velocity information to at least one external device.

14. A vehicle, comprising:

a vehicle body;

at least one vehicle element pivotally mounted to the vehicle body, the vehicle element configured to pivot through an angle not more than 360 degrees; and

means for measuring an angular velocity of the vehicle element.

15. The vehicle according to claim 14, wherein the at least one vehicle element includes at least one of a vehicle door, a lift-gate, a trunk, a hood, a seat-back, a tilt-wheel, and a glove compartment.
