In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the invention discloses a vehicle starting method based on double encryption verification, which comprises the following steps of:

s101, a terminal generates a vehicle starting request and transmits the vehicle starting request to a remote information processing controller configured on a vehicle.

In a preferred embodiment, a scenario in which the terminal generates the vehicle start request may be defined, such as allowing the terminal to generate and issue the vehicle start request only when the vehicle is in the four-door-locked state and in the armed state. One possible implementation may be: when the vehicle is in a four-door locking state and in a fortifying state, a remote information processing controller issues a notification to a terminal so that the terminal can record the current state of the vehicle, and in the current state, the terminal displays an interface for generating and sending a vehicle starting request.

S102, the remote information processing controller interacts with a one-key starting unit configured on the vehicle to carry out first encryption verification, and if the first encryption verification is passed, the one-key starting unit carries out vehicle state detection to judge whether the vehicle meets a starting condition.

In particular, the one-touch start unit may be a keyless one-touch start unit used in a hybrid vehicle.

Specifically, the vehicle state detection by the one-button starting unit may include detecting states such as a door state, a lock state, a defense state, a brake pedal state, a starting switch state, and a power mode state, and if the detection results all meet the vehicle starting requirement, it is determined that the vehicle meets the starting condition, and otherwise, it is determined that the vehicle starting condition is not met.

Further, if the vehicle start condition is not satisfied, the one-touch start unit may feed back a response of the vehicle start failure to the terminal through the telematics controller, and may further describe a specific failure cause in the response of the vehicle start failure, for example, the failure cause may be that the vehicle does not satisfy the start condition.

And S103, if the condition is met, the one-key starting unit interacts with a vehicle starting related module configured on the vehicle to carry out second encryption verification, and if the second encryption verification is passed, the vehicle starting related module starts the vehicle and feeds back a starting result to the one-key starting unit.

Specifically, the one-touch start unit may further feed back a start result to the terminal through a telematics controller.

Specifically, the vehicle start-related modules may include an engine management system, an integrated power controller, and a vehicle control unit.

In one possible embodiment, the one-touch activation unit issues the first message to the telematics controller, and the telematics controller receives the second message, and the first message and the second message may have the same content without transmission errors.

The first encryption algorithm may use a symmetric or asymmetric encryption algorithm.

And S1023, the one-key starting unit receives a second ciphertext from the remote information processing controller, and encrypts the first message by using a first encryption algorithm to obtain a third ciphertext.

And S1024, the one-key starting unit verifies whether the second ciphertext and the third ciphertext are the same.

And S1025, if the two are the same, the first encryption verification is passed.

S1026, if the encryption authentication is different, the first encryption authentication fails.

Further, if the first encryption verification fails, the one-touch start unit may feed back a response of the vehicle start failure to the terminal through the telematics controller, and may further describe a specific failure reason in the response of the vehicle start failure, and if the first encryption verification fails in step S1024, the failure reason may be that the first encryption verification fails.

Specifically, the second encryption verification is shown in fig. 3 and includes:

and S1031, the engine management system generates a third message, encrypts the third message by using a second encryption algorithm to obtain a fourth ciphertext, and sends the third message to the one-key starting unit and the integrated power controller.

Specifically, the third packet may be a randomly generated packet (Challenge).

Specifically, the embodiment of the present invention does not limit the specific types of the first encryption algorithm and the second encryption algorithm, and the first encryption algorithm and the second encryption algorithm may be the same algorithm or different algorithms.

S1032, the one-key starting unit receives a fourth message from the engine management system, encrypts the fourth message by using a second encryption algorithm to obtain a fifth ciphertext, and sends the fifth ciphertext to the engine management system and the integrated power controller.

In one possible embodiment, the engine management system issues the third message to the one-touch start unit, and the one-touch start unit receives the fourth message, and the third message and the fourth message may have the same content without transmission errors.

S1033, the engine management system receives a sixth ciphertext from the one-key starting unit, verifies whether the sixth ciphertext is the same as the fourth ciphertext, and if yes, issues a first verification passing notice to the vehicle control unit.

Further, if the vehicle start failure is not the same as the vehicle start failure, the one-click start unit may feed back a response of the vehicle start failure to the terminal through the telematics controller, and a specific failure cause may be described in the response of the vehicle start failure, for example, the failure cause may be that the engine management system start verification fails.

In one possible embodiment, the one-touch start unit issues the fifth ciphertext to the engine management system, and the engine management system receives the sixth ciphertext, and the fifth ciphertext and the sixth ciphertext may be identical in content without transmission error.

Further, if the vehicle start failure is not the same as the vehicle start failure, the one-click start unit may feed back a response of the vehicle start failure to the terminal through the telematics controller, and a specific failure cause may be described in the response of the vehicle start failure, for example, the failure cause may be failure of the integrated power controller start verification.

In a possible embodiment, the one-touch starting unit issues a fifth ciphertext to the integrated power controller, the integrated power controller can receive the eighth ciphertext, and the content of the fifth ciphertext and the content of the eighth ciphertext can be the same under the condition that no transmission error occurs; and the engine management system issues a third message to the integrated power controller, so that the integrated power controller can receive the fifth message, and the contents of the third message and the fifth message can be the same under the condition that no transmission error occurs.

In the embodiment of the present invention, steps S1033 and S1034 are two execution entities, and the specific execution order thereof is not limited specifically.

And S1035, the vehicle control unit judges whether the vehicle control unit receives the verification passing notification, and if so, the vehicle control unit passes the encryption verification.

Specifically, the vehicle control unit receives a first verification passing notification and a second verification passing notification, and generates a starting control signal, and the vehicle control unit further sends the starting control signal to the one-key starting unit so that the one-key starting unit can execute subsequent actions; further, the vehicle control unit can also perform high-voltage power-on vehicle control components and send power-on success responses to the one-click starting unit.

And the one-key starting unit can inform the terminal vehicle of successful starting after receiving the starting control signal and the successful power-on response.

The vehicle starting method based on the double encryption verification provided by the embodiment of the invention is a technical scheme for realizing safe vehicle starting by multi-terminal interaction of vehicle starting related modules such as a one-key starting unit, a remote information processing controller, an engine management system, an integrated power controller and a vehicle control unit.
