An adaptive vehicle is described that analyzes the dynamic behavior of the vehicle operator based on an operator condition (such as the headway maintained by the operator), a vehicle condition (such as vehicle speed) and environmental conditions (such as precipitation rate and tracking distance maintained by a trailing vehicle) to automatically adapt the vehicle (such as adjusting the transmission shift point schedule) to the driving mood, style or expectations of the vehicle operator.

A system for adaptively controlling the vehicle speed shift point of an automatic transmission of a vehicle in accord with the dynamic characteristics of a vehicle operator, the system comprising, in combination: memory means for storing a schedule of values of headway distances to a preceding vehicle as a function of the values of precipitation rate and vehicle speed, the memory means having memory locations each addressed by a predetermined value of precipitation rate and a predetermined value of vehicle speed; means for sensing the headway distance to a preceding vehicle; means for determining the average of the values of the headway distance to a preceding vehicle; means for sensing the precipitation rate; means for sensing vehicle speed; means for retrieving the stored value of headway distance at the memory location addressed by the sensed value of precipitation rate and the sensed value of vehicle speed; means for comparing the retrieved and sensed values of headway distances to determine the dynamic characteristic of the vehicle operator; means for adjusting the vehicle speed shift point of the transmission (A) downward when the sensed value of the headway distance is greater than the retrieved value and (B) upward when the sensed value of the headway distance is less than the retrieved value; and means for updating the stored value of the headway distance at the memory location addressed by the sensed value of vehicle speed and the sensed value of precipitation rate with the determined average of the values of the headway distance, the vehicle speed shift point of the transmission being adjusted based on the deviation of the sensed value of the headway distance from a norm represented by the average of the values of the headway distance.
