In order for the process and the device to function with as small as possible a number of sensors for operating parameters, a program map (,) is provided from which the intake air pressure (AL) of the charger (,) is derived as a function of the charging pressure (PL), the engine speed (n), and a fuel quantity preset (QK) corresponding to the accelerator position, and there is a device (,) which determines a limit value (QKG,) for the fuel quantity (QK&prime;) metered to the engine (,) as a function of the intake air pressure (AL).

Method and device for protecting a turbo-supercharger

A method for operating an closed-loop control system for injecting fuel into an internal combustion engine, with the control system having an error correcting capability for deviations that occur in the control signal being processed by the control system, and with the control system having a controlling element, which is embodied as a precontrol, PI-controller that are operated in parallel, and a non-volatile memory for storing deviation signals.

The invention is directed to a system for electronically controlling (open loop and/or closed loop) an internal combustion engine of a motor vehicle. By means of at least one measuring unit at least one signal is generated representing the position of a power-determining component and the measuring unit comprises several sensors. The measuring unit is associated with a power-determining component of the vehicle such as a throttle flap or the control rod and/or accelerator pedal. The sensors are checked with respect to their functional capability by comparing the signal values generated by the sensors to each other with respect to a pregiven tolerance range. When a fault of one or more of the sensors is detected, then that sensor or those sensors which is or are unaffected can be determined.
