Abstract: An electronic control unit for controlling at least one function of a vehicle, having at least one input for receiving control-relevant data from at least one sensor, a computer device for processing the control-relevant data and generating control instructions, and at least one output for outputting the control instructions to at least one actuator, and furthermore having a device for limiting the operation of the control unit in time and/or functionality.

Abstract: A method of monitoring a memory of a microcomputer, in particular a RAM memory, using the following steps: provision of a contiguous memory area, in particular a RAM area, which is assigned to a program part to be executed, in particular a task; storage of data to be stored, assigned to the program part, in the contiguous memory area assigned to the particular program part; upon exiting the program part, determination of a check sum on the basis of the data stored in the contiguous memory area; checking of the check sum upon reentry into the program part and/or in regular intervals between exiting from and reentry into the program part; and identification of memory errors, in particular RAM errors, on the basis of a comparison of the check sum ascertained upon exiting the program part and a subsequently obtained and checked check sum.

Abstract: A method of synchronization or a cylinder coordination to a crankshaft position in a multi-cylinder internal combustion engine with a crankshaft which rotates twice per working cycle, comprising the steps of supplying an output signal with a crankshaft transmitter, which per revolution of the crankshaft supplies a reference signal associated with an upper dead point of a cylinder, evaluating the output signal of the crankshaft transmitter by a control device for determining a rotary speed of the crankshaft and for forming injection signals, performing a preliminary synchronization after a detection of the reference signal and releasing a probe injection for an associated cylinder, verifying the preliminary synchronization in the case of a rotary speed increase or a rotary speed acceleration, in the event of a failing rotary speed increase, performing a new preliminary synchronization which is offset by a predetermined angle to release an injection for a cylinder presumably in an upper dead point, and verifyin
