Vehicle assembly having a capacitive sensor

1. A bus comprising:

a vehicle body;

a plurality of capacitive sensors mounted and spaced along an exterior perimeter of the vehicle body, wherein one of the capacitive sensors capacitively couples to an electrically conductive moving object proximal to a portion of the vehicle body such that the capacitance of the one of the capacitive sensors changes;

a controller coupled to the capacitive sensors, the controller analyzing the sensing by the capacitive sensors and providing information about where the moving object is, how fast the moving object is moving, approximate distance of the moving object from the bus, and a direction of travel of the moving object toward and away from the bus, the controller being configured to alert an operator of the bus when the moving object is coupled to the one of the capacitive sensors.

2. The bus as set forth in claim 1 including at least one of the capacitive sensors being disposed forward of at least one wheel coupled to the vehicle body and at least one of the capacitive sensors being disposed rearward of the at least one wheel.

3. The bus as set forth in claim 1 including at least one ultrasonic sensor disposed between a pair of the capacitive sensors.

4. The bus as set forth in claim 1 including a camera system coupled to the vehicle body to visually monitor the moving object relative to the vehicle body.

5. The bus as set forth in claim 1 wherein the vehicle body includes a door opening and at least one door, opening and closing the door opening.

6. The bus as set forth in claim 5 wherein the at least one door includes a weatherseal.

7. The bus as set forth in claim 6 wherein the weatherseal includes at least one of the capacitive sensors.

8. A sensor system for a bus having a vehicle body comprising:

a plurality of capacitive sensors adapted to be mounted to the vehicle body to couple with an electrically conductive moving object proximal to one of the capacitive sensors;

at least one ultrasonic sensor adapted to be mounted to the vehicle body to couple with the moving object relative to the at least one ultrasonic sensor, the at least one ultrasonic sensor being mounted between a pair of the capacitive sensors; and

a controller coupled to the capacitive sensors and the at least one ultrasonic sensor, the controller analyzing the sensing by the capacitive sensors and the at least one ultrasonic sensor and providing information about where the moving object is, how fast the moving object is moving, approximate distance of the moving object from the bus, and a direction of travel of the moving object toward and away from the bus, the controller being configured to alert an operator of the bus when the moving object is coupled to one of the capacitive sensors and the at least one ultrasonic sensor.

9. The sensor system of claim 8 including a camera system in communication with the controller to visually monitor the moving object relative to the vehicle body.

10. The sensor system of claim 8 wherein the at least one ultrasonic sensor includes a plurality of ultrasonic sensors.

11. A bus comprising:

a vehicle body;

a plurality of capacitive sensors mounted along a perimeter of the vehicle body, wherein one of the capacitive sensors capacitively couples to a moving child proximal to the portion of the vehicle body such that the capacitance of the one of the capacitive sensors changes;

a controller coupled to the capacitive sensors, the controller analyzing the sensing by the capacitive sensors and providing information about where the moving child is, how fast the moving child is moving, approximate distance of the moving child from the bus, and a direction of travel of the moving child toward and away from the bus, the controller being configured to alert an operator of the bus when the moving child is coupled to the one of the capacitive sensors.

12. The bus as set forth in claim 11 including at least one of the capacitive sensors being disposed forward of at least one wheel coupled to the vehicle body and at least one of the capacitive sensors being disposed rearward of the at least one wheel.

13. The bus as set forth in claim 11 including at least one ultrasonic sensor disposed between a pair of the capacitive sensors.

14. The bus as set forth in claim 11 including a camera system coupled to the vehicle body to visually monitor the moving child relative to the vehicle body.

15. The bus as set forth in claim 11 wherein the vehicle body includes a door opening and at least one door, opening and closing the door opening.

16. The bus as set forth in claim 15 wherein the at least one door includes a weatherseal.

17. The bus as set forth in claim 16 wherein the weatherseal includes at least one of the capacitive sensors.
