Abstract

A device for reducing slip of drive wheels of a motor vehicle having a turbo charged internal combustion engine includes a charger control unit which controls or regulates the charged air in dependency on at least rotary speed of the engine and in addition on information about the shifted gear in the transmission of the vehicle. For each gear change a maximum permissible time change of rotary speed or in dependency on the rotary speed a maximum permissible charge air pressure is determined experimentally and the latter values are stored in a storing device. By comparing the stored values with the actual values an optimum acceleration of the engine can be obtained. By a simultaneous adjustment of the ignition time point or of the amount of supplied fuel the speed of response of the entire arrangement is further increased.
