Electronic system for a motor vehicle

An electronic control system for a motor vehicle having a drive assembly and a braking apparatus for braking the vehicle, the drive assembly including a motor and a transmission, the electronic control system comprising:

• means for controlling said braking apparatus;
• first means defining an upper hierarchial level and being provided for detecting driver commands and for generating first control commands corresponding to said drive commands;
• second means defining a mid hierarchial level;
• third means for controlling said drive assembly;
• said second means being provided for receiving said first control commands and for generating second and further control commands corresponding to said first control commands for controlling the operating performance of the motor vehicle in accordance with said driver commands and for transmitting said further control commands to said means for controlling said braking apparatus and for transmitting said second control commands to said third means for controlling said drive assembly;
• said third means defining a lower hierarchial level and being provided for receiving said second control commands and for generating third control commands based on said second control commands and for emitting said third control commands for controlling said motor and said transmission to effect a control of said operating performance of said motor vehicle in accordance with said second control commands;
• said second means being a coordinating element adapted to provide the drive commands by acting on said braking apparatus of the vehicle and by controlling the drive assembly of the vehicle while inputting a desired output torque of the drive assembly;
• and ,
• each of the command exchanges taking place between said hierarchial levels in only one direction.
