Method for determining vehicle speed during acceleration of a four-wheel drive vehicle

摘要

It is an object of the present invention to provide a method for controlling the vehicle speed during acceleration of a four-wheel drive vehicle, wherein the vehicle speed during acceleration can be determined with precision. According to the above method, even if a wheel is spinning, the vehicle speed can be correctly determined without any influence of the spin, by correcting the vehicle speed during acceleration by comparison of the determined second vehicle speed, based upon the lowest speed of the four wheels, with the first vehicle speed, which is determined based upon the wheel speed.
