A method for controlling the average speed of a vehicle over a predetermined time period, or indefinitely, or distance length is described with reference to selecting a desired average speed, measuring an actual speed, and maintaining a cumulative error determined as a function of the difference between the average speed and actual speed and the time over which the actual speed measurement was taken. Based on the cumulative total of speed-time error, a compensatory speed is calculated that will reduce the cumulative speed-time error to an acceptable tolerance range within a selected period of elapsed time. Although particularly applicable to competition situations in which an average speed is dictated for use over a particular competition course, the average speed controlling method can be used in other situations where the average speed of a vehicle must be controlled.

1. A method for controlling the average speed of a vehicle, comprising the steps of:measuring elapsed time; defining a desired average speed; measuring an actual speed of said vehicle; calculating an error magnitude as a function of said desired average speed and said actual speed; determining a cumulative error magnitude of said vehicle as a function of said error magnitude and said elapsed time; selecting a period of elapsed time over which an absolute value of said cumulative error magnitude is to be reduced to a predetermined magnitude; and determining a compensatory speed of said vehicle, as a function of said cumulative error and said period of elapsed time, which will reduce said cumulative error magnitude to said predetermined magnitude within said period of elapsed time.
