Abstract

A distance detecting device is mounted on a user'"'"'s vehicle to detect a distance between the user'"'"'s vehicle and a leading vehicle moving in front of the user'"'"'s vehicle. The distance detecting device communicates with a processing device, which applies race based distance rules to determine whether the user'"'"'s vehicle is close to or incurring a penalty based at least on the distance between the user'"'"'s vehicle and the leading vehicle. An indication can be given to the user regarding an impending penalty and/or when a penalty is incurred. Similarly, the device can be read to apply a penalty. Various modifications can be made to allow for recording, display, and transmission of racing and penalty statistics, enabling and disabling recordation of penalty occurrences, tailoring the penalty determinations to a given race, and mounting the distance detecting device to a vehicle.

11. The apparatus of claim 2 further comprising a wireless receiver operatively connected to the processing device and configured to receive a disable wireless signal from a wireless transmitter located along a race route, wherein the processing device is configured to not monitor the signal to determine whether the user'"'"'s vehicle is within the penalty distance in response to receiving a disable signal from the wireless receiver.

12. The apparatus of claim 11 further comprising the wireless receiver'"'"'s being configured to receive an enable wireless signal from a wireless transmitter located along the race route, wherein the processing device is configured to re-enable monitoring the signal to determine whether the user'"'"'s vehicle is within the penalty distance in response to receiving an enable signal from the wireless receiver.

13. The apparatus of claim 2 wherein the processing device is configured to:

receive speed signals regarding a speed of the user'"'"'s vehicle;

determine an approximate location of the user'"'"'s vehicle based on a recorded history of the user'"'"'s vehicle'"'"'s speed;

not monitor the signal to determine whether the user'"'"'s vehicle is within the penalty distance in response to determining that the user'"'"'s vehicle is in a portion of a race course exempt from drafting penalties.

14. The apparatus of claim 2 wherein the processing device is further configured to control the indicator to provide a real-time indication to the user regarding a determination of whether the user'"'"'s vehicle is within the penalty distance from a leading vehicle.

15. An apparatus for monitoring distance behind a moving vehicle, the apparatus comprising:
