Abstract:
1. A method for assisting calculation of a vehicle speed in a vehicle having a braking system, the method comprising: decelerating individual wheels, via a braking device, of at least one vehicle axle, wherein the vehicle includes an axle differential; decelerating the vehicle via a drive train, one wheel of the vehicle axle being additionally impinged upon, by the braking system, with a greater braking torque than an opposite wheel disposed on the same vehicle axle; and ascertaining, using a processor, the vehicle speed based on a rotation speed of the opposite wheel; wherein one axle differential is disposed respectively on at least two vehicle axles, and one wheel of the at least two vehicle axles is respectively decelerated, wherein rotation speeds of one of undecelerated or less-decelerated wheels being taken as the basis for ascertaining the vehicle speed, and wherein diagonally oppositely located wheels of the two vehicle axles are decelerated.
