ABSTRACT:
A plurality of control maps which are used to control the position of an engine throttle valve or similar device which effects the power output of the engine, are stored in memory. The wheel slip of the vehicle is monitored and if found to be in excess of an allowable limit or limits the control map currently in use is changed or downgraded to one which exhibits less rapid engine power generation characteristics. On the other hand, if the rate at which a control element such as an accelerator pedal is moved in direction which demands increased engine output is greater than zero; the amount of wheel slip is below the allowable limit or limits; and the control signal being produced by the instant control map is at its maximum permissible level for the instant position of the control element, then the currently used map is upgraded to one which permits increased and more rapid engine power development. Alternatively, it is possible to define upper and lower accelerator depression limits and use these in a manner that when the depression is below the lower limit map upgrading is inhibited while when above the limit upgrading is induced if the slip ratio remains at an acceptable level for a selected period of time.
