A method for monitoring the functioning of a control unit for the activation of output stages, for example, in a motor vehicle, is provided. The control unit includes a main computing element having at least one microprocessor, and at least one auxiliary computing element having at least one microprocessor. The main computing element and the at least one auxiliary computing element may access a common memory element. The present invention enables monitoring of the control unit that is as simple as possible but is nonetheless secure and reliable, by providing that during normal operation of the control unit, the content of a specifiable memory location of the memory element be queried by at least one of the auxiliary computing elements at presettable times, given a functioning main computing element, the content having previously been written with a presettable value by the same.
A method for monitoring a functioning of a control unit for activating output stages in a motor vehicle, the control unit including a main computing element having at least one microprocessor, and at least one auxiliary computing element having at least one microprocessor, the main computing element and the at least one auxiliary computing element having access to a memory element, comprising:
A computer-readable memory medium storing a set of instructions adapted to be executed by at least one of a main computing element of a control unit and at least one auxiliary computing element, to activate output stages in a motor vehicle, the set of instructions performing the steps of:
A control unit for activating output stages in a motor vehicle, comprising:
