A wheeled motor vehicle and a method for controlling the flow of electric power of an electric system of such a vehicle

摘要

A wheeled motor vehicle comprises an electric motor (4) config- ured to assist a driver of the vehicle to steer the vehicle and an electric system comprising an arrangement configured to provide electric power to the electric motor and other consumers (10-13) of electric power of the vehicle. A data collector is arranged to collect data useable for calculating/estimating a maximum electric power possibly needed for accurate function of the electric motor and a control unit (8) calculates/estimates said maximum electric power and controls the arrangement to have an amount of electric power possible to deliver to the electric motor exceeding said max- imum electric power.
