Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A vehicle start control method according to an embodiment of the present invention will be described below.
The vehicle start-up control method according to the embodiment of the invention is described below with reference to fig. 1 to 2, and as shown in fig. 1, the vehicle start-up control method of the embodiment of the invention includes at least steps S1 to S4.
And step S1, after receiving the vehicle starting request signal, respectively authenticating the smart key, the electronic steering column lock and the vehicle control unit in sequence.
In an embodiment, the smart key is, for example, a smart key that is matched to a vehicle and can emit an infrared signal. Specifically, after a driver enters a vehicle with the intelligent key, the driver steps on a brake and presses a Start switch, at the moment, a vehicle Start request signal is received, a PEPS (Passive Entry Passive Start) controller drives a low-frequency antenna and sends a low-frequency signal to search the intelligent key, and after receiving the low-frequency signal, the intelligent key replies high-frequency authentication information to the PEPS controller to authenticate the intelligent key. If the intelligent key is successfully authenticated, the intelligent key is considered to be a valid key, namely the intelligent key is matched with the intelligent key of the current vehicle; if the intelligent key is not successfully authenticated, the intelligent key is not considered to be a legal and effective key, and the vehicle cannot be started.
After the smart key is successfully authenticated, the keyless smart system sends a Steering wheel unlocking request to an ESCL (electronic Steering column Lock), and after the electronic Steering column Lock receives the unlocking request, the electronic Steering column Lock sends an authentication request to the keyless smart system and authenticates the electronic Steering column Lock.
If the electronic steering column lock is successfully authenticated, replying to the keyless intelligent system that the authentication is passed; and if the electronic steering column lock is not successfully authenticated, replying to the keyless intelligent system that the authentication is failed.
After the electronic steering column lock is successfully authenticated, the electronic steering column lock is unlocked, when the vehicle meets a starting condition, the keyless intelligent system sends an anti-theft authentication request to a VCU (vehicle Control Unit), and the vehicle Control Unit authenticates the vehicle Control Unit after receiving the anti-theft authentication request. In a specific embodiment, the vehicle satisfying the start condition includes, for example: the keyless smart system controller controls the IG relay to be attracted to the ON gear, and the vehicle meets other starting requirements, such as no fault of the vehicle, sufficient battery capacity and the like.
And step S2, after the smart key, the electronic steering column lock and the vehicle controller are successfully authenticated, sending a vehicle starting permission instruction to the vehicle controller so that the vehicle controller can control the vehicle to start.
In the embodiment, after the intelligent key, the electronic steering column lock and the vehicle controller are determined to be successfully subjected to anti-theft authentication, the current anti-theft risk of the vehicle is considered to be small, at the moment, the keyless intelligent system sends a vehicle starting permission instruction to the vehicle controller, and the vehicle controller controls the vehicle to be in a starting state after receiving the starting instruction.
And step S3, after the vehicle control unit controls the vehicle to start, the controller is authenticated.
In an embodiment, after the vehicle is successfully started, the controller, such as an EMB (Electronic mechanical Brake System) is authenticated based on further consideration of vehicle anti-theft security.
Specifically, after the vehicle is started successfully, a user steps on a brake to engage a gear to drive, at the moment, the line control controller controls the wheel brake of the vehicle to enable the wheel to be incapable of rotating, and an authentication request is sent to the line control controller to authenticate the line control controller. By adding the authentication on the line control controller after the vehicle is successfully started, the vehicle still cannot be driven after the authentication on the intelligent key, the electronic steering column lock and the vehicle controller is successful due to relay attack, and the anti-theft safety of the vehicle is improved.
And step S4, after the controller is successfully authenticated, a driving permission instruction is sent to the controller, so that the controller unlocks the wheel braking force according to the driving permission instruction, and the vehicle normally runs.
In the embodiment, after the controller is determined to be successfully authenticated, the vehicle is considered not to be subjected to relay attack and is in a normal starting state, and at the moment, a driving permission command is sent to the controller, so that the controller controls to release the wheel braking force according to the driving permission command, and the vehicle can normally run.
According to the vehicle starting control method provided by the embodiment of the invention, based on the security consideration of vehicle theft prevention, the intelligent key, the electronic steering column lock and the vehicle control unit are sequentially authenticated, after the sequential authentication is successful, a vehicle starting permission instruction is sent to the vehicle control unit, so that the vehicle control unit controls the vehicle to start, after the vehicle control unit controls the vehicle to start, the controller is further authenticated, and after the controller is successfully authenticated, a vehicle driving permission instruction is sent to the controller, so that the controller unlocks the wheel braking force according to the vehicle driving permission instruction, so that the vehicle normally runs, the vehicle is greatly reduced in the theft risk when the vehicle is attacked by a relay while the multiple authentication of the vehicle is realized, and the security of vehicle theft prevention is improved.
In some embodiments, before authenticating the controller, the method further comprises: receiving an intelligent key authentication request sent by a controller to authenticate the intelligent key again; and after the smart key is successfully authenticated again, authenticating the controller.
In an embodiment, after the vehicle controller controls the vehicle to start, the vehicle controller receives an intelligent key authentication request sent by the controller to authenticate the intelligent key again, and after the keyless intelligent system searches for and replies to the intelligent key, the controller is authenticated after considering that the intelligent key is successfully authenticated again, that is, after the intelligent key is determined to be legal. Before the controller is authenticated, the re-authentication of the intelligent key is added, so that the vehicle using safety of the user can be further ensured.
In some embodiments, the vehicle launch control method further comprises: and after the smart key fails to be authenticated again or the controller fails to be authenticated, a driving forbidding command is sent to the controller, so that the controller maintains the wheel braking force according to the driving forbidding command to forbid the vehicle from driving.
