Microprocessor Clutch Control 830628

The authomatic control of a normal production mechanical clutch has the objective of increasing driver confort in urban traffic. Such a device will require a well suited control strategy and a very carefull experimental analysis to ensure correct and reliable operation during the start of the vehicle and gears shifting operation. To approach this problem, Fiat Research Center has developed on Fiat Panda 30 a microcomputer based control system that drives an appropriate clutch pneumatic actuator. This paper illustrates, in some details, the pneumatic-mechanical actuation system, the sensors used, the control strategy and the electronic controller structure.
