Problems solved by technology

However, it has been found in practice that since PEPS and VCU use a single verification algorithm and a single key to perform security verification on the vehicle, if the verification algorithm and key are leaked, the safety of the vehicle will be compromised. Can not be guaranteed, it can be seen that the reliability of the current vehicle safety verification is low

Embodiment 1

[0068] see figure 1 , figure 1 It is a schematic flowchart of a vehicle verification method disclosed in an embodiment of the present invention. Such as figure 1 As shown, the vehicle verification method may include the following steps:

[0069] 101. When a low-voltage system wake-up command of the vehicle is detected, the vehicle verification device acquires the security code transmitted by the vehicle key.

[0070] In the embodiment of the present invention, to make the vehicle work normally, both the low-voltage system and the high-voltage system of the vehicle need to be awakened. The low-voltage system can be awakened by performing power-on operation to the low-voltage system, and the high-voltage system can be awakened after the low-voltage system is awakened. The high-voltage system is implemented by performing a power-on operation. In order to ensure the safety of the vehicle, a first safety check can be performed before waking up the low-voltage system, and a secon...

Embodiment 2

[0084] see figure 2 , figure 2 It is a schematic flowchart of another vehicle verification method disclosed in the embodiment of the present invention. Compared with the first embodiment, the embodiment of the present invention explains in more detail the implementation method of the second safety check, and also adds the method of using the vehicle under the low-voltage system, which not only ensures the safety of the electric output of the vehicle, but also ensures Safety of low-voltage batteries. Such as figure 2 As shown, the vehicle verification method may include the following steps:

[0085] 201. When a low-voltage system wake-up command of the vehicle is detected, the vehicle verification device acquires the security code transmitted by the vehicle key.

[0086] 202. The vehicle verification device controls the vehicle's keyless entry and start system PEPS and the low-voltage system to perform a first security verification on the security code based on the first v...

Embodiment 3

[0106] see image 3 , image 3 It is a schematic flowchart of another vehicle verification method disclosed in the embodiment of the present invention. Compared with Embodiment 2, the embodiment of the present invention adds a way to perform multiple safety checks on the vehicle, and also adds a mechanism to freeze the vehicle when the vehicle fails to pass multiple safety checks, which not only improves safety The reliability of the calibration can also enable the owner to know the safety status of the vehicle in a timely manner. Such as image 3 As shown, the vehicle verification method may include the following steps:

[0107] Steps 301 to 304 are the same as steps 201 to 204, and the following content will not be repeated.

[0108] 305 . The vehicle verification device judges whether the second safety verification is passed, if yes, execute step 306 ; if not, execute step 307 .

[0109] 306. The vehicle verification device determines that the vehicle passes the safety...

Abstract

The invention relates to the technical field of vehicles, and discloses a vehicle calibration method and device, and a vehicle. The vehicle calibration method comprises the steps that a security codetransmitted by a vehicle key is acquired when a low-voltage system wake-up command of the vehicle is detected; a keyless entry of the vehicle is controlled, and a PEPS (passive entry passive start) and the low-voltage system are controlled to perform a first security check on the security code based on a first verification algorithm and a first security key; when the first security check is passed, the PEPS and a high-voltage system of the vehicle are controlled to perform a second security check on the security code based on a second verification algorithm and a second security key, wherein the first verification algorithm is different from the second verification algorithm, and / or the first security key is different from the second security key; when the second security check is passed,it is determined that the vehicle passes a security check. By implementing the vehicle calibration method and device, and the vehicle, it is ensured that in the case where any of the verification algorithms or security keys is leaked, the security of the vehicle is less affected, and thus reliability of the security check of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle verification method and device, and a vehicle. Background technique [0002] At present, electric vehicles on the market usually have the function of safety and anti-theft verification. When the electric vehicle is tried to start, the security code in the car key can be obtained, and the keyless entry and start system (PassiveEntry Passive Start) in the electric vehicle can be activated. , PEPS) and the Vehicle Control Unit (Vehicle Control Unit, VCU) perform security verification on the vehicle based on the security code. However, it has been found in practice that since PEPS and VCU use a single verification algorithm and a single key to perform security verification on the vehicle, if the verification algorithm and key are leaked, the safety of the vehicle will be compromised. Can not be guaranteed, it can be seen that the reliability of the current vehicle safety ...
