Abstract
A device and method for measuring the slope of a road on which a vehicle travels, which includes a gear position sensing member for outputting a corresponding signal after sensing the gear position, or a car speed sensing member for outputting a corresponding signal after a driving speed of the vehicle, an engine revolution sensing member for outputting a corresponding signal after sensing the engine revolution number, a loading degree sensing member for outputting a corresponding signal after sensing the loading degree which is changed by a driving condition of the vehicle, a brake pedal sensing member for outputting a corresponding signal after sensing the brake pedal operation which is changed by the operation of the brake pedal, and an engine controlling member connected to the gear position sensing member, or the car speed sensing member, the engine revolution sensing member, the loading degree sensing member, and the brake pedal sensing member, whereby the engine controlling member calculates an engine torque when the error value is within the setting value, and finally measures the slope of a road surface by using the calculated engine torque.
