1. A motor vehicle including a control unit for determining the energy loss resulting from clutch slippage, said vehicle comprising:
- a memory associated with the control unit for storing vehicle operating data, means for determining the distance traveled by the vehicle, whereby the vehicle operating data are associated with the distance traveled by the vehicle and are stored as paired values in the memory, means for determining clutch slippage energy loss based upon engine rotational speed, transmission input rotational speed, and torque transmitted by the clutch, and means for determining a set point value for actuation of one of a clutch, a brake, and a transmission based upon the stored paired values.

Abstract
A vehicle including a device for determining vehicle operational data and for determining distance traveled by the vehicle. A memory is provided for storing the operational data together with the distance traveled as paired values for subsequent diagnostic and maintenance purposes. Signals representative of engine rotational speed, transmission input rotational speed, and torque transmitted by the clutch are sensed for determining clutch performance loss values, and the performance loss values are stored in the memory as paired values along with the vehicle distance traveled.
