Abstract

The invention discloses a controller for an automobile. The controller comprises a first CAN (controller area network) transceiver, a second CAN transceiver and a processor, wherein the processor comprises a first processor core and a second processor core, and the same processing program is run by the first and second processor cores; the first CAN transceiver is used for receiving a first CAN signal from the first processor core, and transmitting a first feedback signal; the first processor core is used for generating the first CAN signal, judging whether the first CAN transceiver fails or not according to the first CAN signal and the first feedback signal, and controlling the first or second CAN transceiver which fails to stop transmitting a CAN signal when the first or second CAN transceiver is determined to fail. The controller is simple in structure, quick in safe response, low in cost and applicable to the field of safety control. The invention also discloses the automobile and a monitoring method for the controller for the automobile.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a controller for automobiles, an automobile with the same, and a monitoring method for the controller for automobiles. Background technique [0002] With more and more electronic functions in automobiles, programmable systems become more and more complex, and safety issues become more and more prominent. The safety of the controller system is related to the realization of the functions of the entire vehicle system. [0003] The CAN bus was invented by BOSCH. It adopts CRC check and uses differential level signals for transmission. It is a multi-master and safer bus. It is widely used in automotive electronics and industrial fields. However, the CAN bus system also has its inherent failure modes, including bus short circuit to power supply, ground short circuit, CAN bus open circuit, and the reliability of electronic components such as CAN transceiver itself. ...
