Abstract
Disclosed is a fuel-saving driving evaluation system which provides a driver with advice suitable for the driver based on fuel-saving driving evaluation standards which correspond to the fuel-saving driving proficiency level of the driver, so that the driver is relaxed and the fuel-saving driving skill of the driver is gradually improved. The fuel-saving driving evaluation system is comprised of an engine speed measuring device, a vehicle speed measuring device, a fuel flow measuring device, and a control device. The control device has a function to store several kinds of standard values and target values of parameters (driving operation parameters) for evaluating the fuel-saving driving level in the vehicle to be evaluated, and a function to determine the standard values and the target values of the parameters based on control signals sent from outside of the control device.
