State control system of digital signal processor and vehicle

The embodiment of the utility model discloses a state control system of a digital signal processor and a vehicle. The system comprises a CAN bus, a CAN transceiver, a comparator, a controller and a digital signal processor, the CAN bus is connected with the CAN transceiver, the CAN transceiver is connected with the comparator, the comparator is connected with the controller, and the controller is connected with the digital signal processor; wherein the CAN transceiver is used for receiving a CAN message differential signal sent by a CAN bus; the CAN message differential signal comprises a first message differential signal and a second message differential signal; the comparator is used for generating a relation signal reflecting the size relation between the first message differential signal and the second message differential signal; and the controller is used for controlling the state of the digital signal processor to be switched between a working mode and a sleep mode according to the relation signal.
