  • Method for estimating the longitudinal speed of a motor vehicle
    Patent number: 7962310
    Abstract: A method for estimating longitudinal speed of a motor vehicle, including two drive wheels and at least one central electronic unit, based on rotational speeds of the four wheels two of which are drive wheels, such that, after arranging the rotational speeds in descending order: in an acceleration phase, the vehicle longitudinal speed is compared with the speed of the third fastest wheel, and its acceleration should not exceed that of the slowest wheel; in a deceleration phase, the longitudinal speed is compared with the speed of the fastest wheel and its acceleration in absolute value should not exceed that of the second fastest wheel; when the longitudinal speed ranges between the speed of the third fastest wheel and that of the fastest wheel, its value remains constant.
