Abstract
A process of forming a value of standard resistance for an automotive vehicle and a vehicle control system are disclosed. The process comprises sensing operating parameters indicative of operating conditions of the vehicle power train during operating an engine to keep the automotive vehicle rolling over the surface of a flat road in steady running state at each of said predetermined number of reading points of vehicle speed, A value of driving torque produced by the power train is derived from the sensed operating parameters at each of the predetermined number of reading points of vehicle speed. Finally, the derived values of driving torque are set as known standard resistance values at the predetermined number of reading points of vehicle speed, respectively.
