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).

Method for controlling a drive system and/or a wheel brake system

A control system for an automatically shifting transmission is described. A direct upshifting or downshifting starting from the automatic mode is permitted, by using a corresponding programming of the electronic control device when a certain selecting device is operated, without transition into the manual mode taking place. A gear change following this upshifting or downshifting is implemented, corresponding to the shifting logic of the automatic mode. In the case of a multiple operation, multiple direct upshifts or downshifts can also be permitted, without leaving the automatic mode.

Device for controlling an automatic gearbox

A method for controlling a drive system in a motor vehicle having at least one electronic control device, which detects the accelerator pedal position as an input signal and therefrom, corresponding to a basic characteristic curve, determines a wheel torque desired by the driver, the control device receives information concerning the presence of wheel slip as another input signal and, when wheel slip is present, stores a limit torque. For an accelerator pedal position which is greater than the accelerator pedal position at which the wheel slip has occurred, the basic characteristic curve is changed in that the desired wheel torque is limited to the limit torque.

Anti-slip control method for a drive system in a motor vehicle

An arrangement for controlling an infinitely variable vehicle transmission includes an adjusting element which is operable in two modes. In a first mode, the adjusting element can be actuated to select from predetermined transmission gear settings. In the second mode, it can be actuated to cause a continuous adjustment of the vehicle gear. The direction, speed and manner of such adjustment depend on the manner in which the adjusting element is actuated, and optionally vehicle operating parameters. In addition, the adjusting element can be used to select from among driving control modes based on predetermined algorithms, for achieving maximum economy or maximum performance.
