Abstract

The invention relates to the field of automobile control and in particular relates to an automobile main controller awakening system and an automobile main controller awakening method as well as an automobile. The automobile main controller awakening system comprises a CAN bus and a main controller of the automobile and a CAN bus transceiver of the automobile, and also a power awakening module which is connected with the main controller of the automobile and a data awakening module which is connected with the main controller and the CAN bus transceiver; the main controller is connected with the CAN bus transceiver. The invention provides the new automobile main controller awakening system and the new automobile main controller awakening method as well as the automobile. The main controller enters a sleep mode by configuring the main controller and the CAN bus transceiver of the automobile; besides, the main controller can be awakened by use of hardware without software interference, and therefore, a software resetting function is realized. As a result, the response time of the system is greatly reduced and the efficiency of the system is greatly improved, and the time is saved.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a wake-up device and method for an automobile main controller and a vehicle. Background technique [0002] Automotive electronics is currently the most attractive field in the electronics industry. Regardless of its development prospects, stability and gross profit margin, it is much better than other electronics fields. The core of the automotive electronics field is the main controller of the car. [0003] A major task of the main controller of the car is to realize the dormancy and wake-up of the car CAN bus, and the dormancy of the car CAN bus can reduce the static power consumption of the bus, so as to realize the low power consumption of the electronic control unit (ECU), and then turn off the ECU, Finally, the purpose of reducing the static power consumption of the vehicle is achieved. [0004] However, when the main controller of the car wakes up again after going to sl...
