Control device for a motor vehicle

A control unit for a motor vehicle, the control unit comprising:

• a microprocessor (2) comprising at least first and second computation cores (5, 6),
• a monitoring module (7) being separated from the microprocessor (2),
• an evaluation module (3) for evaluating input signals provided by sensors, and
• an activation module (4) comprising at least one end stage for producing output signals for activating actuators,
• such that:
• a control function being implemented in the first computation core (5),
• a monitoring function for the first computation core of the microprocessor being implemented in the second computation core (6) of the microprocessor,
• a monitoring function for the second computation core of the microprocessor being implemented in the monitoring module (7), and
• such that:
• starting from at least one of the first computation core (5) of the microprocessor, the second computation core (6) of the microprocessor and the monitoring module (7), a switch-off module (8) being activated for switching off the at least one end stage of the activation module (4).

A control unit for a motor vehicle, the control unit comprising:

• an evaluation module (3) for receiving and evaluating input signals transmitted by sensors;
• a microprocessor (2) for directly communicating with the evaluation module (3) and comprising at least first and second computation cores (5, 6), the first computation core (5) facilitating initiation of a control function for controlling operation of an assembly of the motor vehicle, the second computation core (6) being directly associated with and monitoring functioning of the first computation core (5);
• a monitoring module (7) being independent from the microprocessor (2), and the monitoring module (7) being directly associated with and monitoring functioning of the second computation core (6), and the first computation core (5) being associated with and monitoring functioning of the monitoring module (7);
• a switch-off module (8) directly communicating with each of the first and the second computation cores (5, 6) and the monitoring module (7);
• an activation module (4) comprising at least one end stage for producing and transmitting output signals for actuating actuators, the activation module (4) directly communicating with the switch-off module (8) and the switch-off module (8) switches off the at least one end stage of the activation module (4) when the functioning of one of the first computation core (5), the second computation core (6), and the monitoring module (7) is determined to be faulty by a respectively associated one of the first computation core (5), the second computation core (6), and the monitoring module (7).
