Method for determining rolling resistance of motor car, involves forming mean value from traction resistance values over distance traveled based on defined travel track intervals, and computing rolling resistance based on mean value

摘要

The method involves determining a rolling resistance based on traction resistance values. A mean value is formed from the traction resistance values over a distance traveled based on defined travel track intervals. The rolling resistance is computed based on the mean value. A traction resistance value is determined based on a vehicle speed pulse for each defined route interval of a route, where the mean value is determined as an arithmetical mean value. Fixed number of successive traction resistance values is determined. An independent claim is also included for a control device of a motor car.
