Detailed Description
The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.
Example 1:
embodiment 1 provides an anti-theft system for an electric vehicle and a control method thereof, which are low in cost and good in anti-theft effect.
As shown in fig. 1, the anti-theft system of the electric vehicle of the embodiment is composed of a vehicle controller, a vehicle body controller, a brake switch, a brake control device, a P-gear controller, and a gear display device, which are respectively connected to the vehicle controller; the vehicle body controller is connected with a starting request switch and a vehicle lamp and is in communication connection with a remote control key; the P gear controller is connected with a P gear locking device; the P-gear controller has a delayed power-off function.
The brake switch is used for detecting a starting request of the vehicle, and the driver is indicated to enter a defense releasing state to start the vehicle only when the brake switch is pressed down and the starting request switch is pressed down at the same time.
The starting request switch is not only used for detecting the starting request of the vehicle, but also can detect whether the vehicle is in a power supply off state or not, and provides reference for the vehicle to enter a fortification state.
The brake control device provides the current vehicle speed value to the vehicle control unit to judge the vehicle state.
The gear display device provides current gear information for the vehicle control unit to judge the vehicle state.
The car light is used for providing warning signals, and timely warning is provided for users after problems occur in the locking and unlocking processes.
The P-gear controller is used for controlling gears, and the P-gear locking device can lock and unlock the P-gear.
All the above components are in the prior art, and the structure and the working principle thereof are not described in detail herein.
The control method of the anti-theft system of the electric automobile of the embodiment comprises P gear locking and P gear unlocking.
As shown in fig. 2, the P-range lock-up flow is as follows: when the vehicle body controller detects that the power supply is turned off, the vehicle speed is zero and the vehicle door is locked, the vehicle is considered to meet the condition of entering a fortification state; when the vehicle meets the condition of entering a fortifying state, the vehicle body controller sends a fortifying state signal to the vehicle controller, the vehicle controller drives the P gear locking device through the P gear controller to lock the P gear, the P gear controller automatically switches the gear to the P gear at the moment, and the P gear locking device locks the P gear; the P gear controller feeds back the P gear state to the whole vehicle controller after executing the P gear lock stopping action; if the P gear locking is not successfully carried out, the whole vehicle controller carries out flash light warning through the vehicle body controller; if the P gear locking is successfully carried out, the vehicle control unit controls the P gear controller to be powered off.
The door lock includes a key for pressing a remote key, and if the vehicle is equipped with a keyless entry system, a key on a door handle is pressed.
As shown in fig. 3, the process of P-range unlocking is as follows: when the vehicle controller detects that the vehicle speed is zero, the brake pedal is stepped on and the starting request switch is pressed down, the vehicle is considered to enter a defense solving state from a defense setting state; the vehicle body controller sends a defense deactivation state signal to the vehicle controller after the vehicle enters a defense deactivation state from a defense deactivation state, the vehicle controller firstly judges whether the current gear is in a P gear or an N gear after receiving the defense deactivation state signal, and if the current gear is in the N gear, the vehicle controller directly enters a READY state; if the current gear is in the P gear, the vehicle control unit drives the P gear locking device through the P gear controller to unlock the P gear, the P gear locking device releases the locking of the P gear, and the P gear controller automatically switches the gear to the N gear; the P-gear controller feeds back a P-gear state to the vehicle control unit after executing a P-gear unlocking action, the vehicle control unit enters a READY state after receiving the feedback of P-gear unlocking success, and the vehicle control unit carries out light warning through the vehicle body controller after receiving the feedback of P-gear unlocking failure.
