condition evaluation of a system for displacement of motorized vehicle

The present invention relates to a driving condition assessment system which comprises a rotational speed detecting section (5b) for detecting an engine rotational speed of the motor moving vehicle as measured rotational speed, a degree detecting section accelerator opening (5a) for detecting a degree of accelerator opening, means for calculating a degree of engine load (150) for calculating a degree of engine load from a degree of partial load and a maximum degree of charge for each degree of accelerator opening, and driving information generating means (60) for evaluating a driving condition of the vehicle on the based on said level of engine load and generate an appropriate driving information for the vehicle.
