After connection, the Bluetooth key information transmitted from the mobile phone end is checked, bidirectional authentication and vehicle control instruction analysis are completed with the mobile phone end based on a Bluetooth protocol self-set by a vehicle manufacturer, and the vehicle control instruction is transmitted to the ECU unit for processing through CAN communication.
And the ECU receives the vehicle control instruction analyzed by the vehicle-end Bluetooth communication unit and distributes the instruction to the vehicle control execution unit.
The vehicle control execution unit directly executes a vehicle control instruction transmitted by the ECU, controls corresponding vehicle parts such as a vehicle door, a vehicle window and a trunk to work, and feeds back a controlled result to the state feedback unit.
And finally, the state feedback unit processes the vehicle control instruction execution result of the vehicle control execution unit into a corresponding CAN communication signal, and the CAN communication signal is returned to the ECU.
