Abstract
A method for controlling a drive system and/or a wheel braking system, a total braking torque consisting of a drive braking torque and/or a wheel braking torque to be applied to the wheels of a motor vehicle is adjusted such that the desired wheel braking torque is reduced by an amount which can be compensated by a (preferably maximally) possible increase of the drive braking torque, when the wheel braking system is particularly loaded and when the vehicle velocity is approximately constant (steady-state) operating mode. However, the increase of the drive braking torque is limited to a predefined amount (preferably achievable in the fired coasting operation) when the wheel braking system is loaded less highly or the vehicle velocity changes (dynamic operating mode).
