Abstract
A method for operating a control unit of a motor vehicle. A status inquiry is transmitted by a watchdog unit to a first monitoring unit, which is implemented on a first processor core of a multicore processor. A status response is ascertained by the first monitoring unit as a function of the status inquiry. A fault is ascertained by the watchdog unit as a function of the status response.
Claims12
A method for operating a control unit of a motor vehicle, comprising:
- transmitting a status inquiry by a watchdog unit to a first monitoring unit, which is implemented on a first processor core of a multicore processor;
- ascertaining, by the first monitoring unit, a status response as a function of the status inquiry;
- ascertaining, by the watchdog unit, a fault as a function of the status response;
- ascertaining, by a first self-testing unit, a first test result, the first self-testing unit being implemented on the first processor core;
- ascertaining, by a second self-testing unit, a second test result, the second self-testing unit being implemented on a second processor core of the multicore processor;
- and
- ascertaining, by a second monitoring unit, a third test result as a function of the second test result;
- and
- wherein the status response is ascertained by the first monitoring unit as a function of the first test result, and as a function of the third test result.
