Abstract

Embodiments of the present disclosure relate to vehicle technologies, and disclose a method and system for controlling a vehicle, and a fingerprint chip. The method comprises: collecting a fingerprint image of a user; authenticating the user according to the fingerprint image and acquiring identity information of the user after the authentication succeeds; acquiring a vehicle personalization parameter of the user according to the identity information of the user and setting up the vehicle according to the vehicle personalization parameter. The embodiments further provide a vehicle control system and a fingerprint chip. The technical solutions provided by the embodiments of the present disclosure can allow simple and quick personalized settings of a vehicle based on identity recognition, which can facilitate sharing a vehicle among family members in most cases.

First claim

What is claimed is:

1. A method for controlling a vehicle, applied to the vehicle that comprises a fingerprint chip mounted on a start button of the vehicle, the fingerprint chip comprising a fingerprint sensor, such that when a finger of a user presses the start button, the finger faces a fingerprint collection surface of the fingerprint sensor, comprising:
collecting, by the fingerprint sensor, a fingerprint image of a user;
entering a fingerprint authentication mode when a microprocessor integrated in the fingerprint chip of the vehicle receives a command of enabling a fingerprint authentication function from a start controller; wherein the command of enabling the fingerprint authentication function is generated by the start controller at least when detecting that the start button is pressed;
in the fingerprint authentication mode, authenticating the user according to the fingerprint image and acquiring identity information of the user after the authentication succeeds; and
acquiring a vehicle personalization parameter of the user according to the identity information of the user and setting up the vehicle according to the vehicle personalization parameter;
the method further comprising:
when detecting a fingerprint entry request, disabling a detection function of the start controller on whether a start button is pressed, and sending a command of enabling a fingerprint entry function to a microprocessor;
entering a fingerprint entry mode after the microprocessor receives the command of enabling the fingerprint entry function; and
in the fingerprint entry mode, generating, by the microprocessor, a fingerprint template according to the fingerprint image, and establishing correspondence between the fingerprint template and the identity information of the user that is received through a central control device of the vehicle.

2. The method according to claim 1 ,
wherein authenticating the user according to the fingerprint image and acquiring identity information of the user after the authentication succeeds comprises:
authenticating, by the microprocessor integrated in the fingerprint chip of the vehicle, the user according to the fingerprint image and acquiring the identity information of the user after the authentication succeeds.

3. The method according to claim 2 , wherein
after authenticating the user, by the microprocessor according to the fingerprint image, the method further comprises:
upon the authentication succeeding, notifying, by the microprocessor, the start controller of the vehicle to start the vehicle.

4. The method according to claim 2 , wherein the method further comprises:
performing, by the microprocessor, live detection through an infrared sensor integrated in the fingerprint chip, and authenticating, by the microprocessor, the user according to the fingerprint image after the detection succeeds.

5. The method according to claim 2 , wherein after authenticating the user, by the microprocessor according to the fingerprint image, the method further comprising:
upon the authentication failing, re-collecting the fingerprint image and recording a number of times the authentication fails; and
stopping re-collecting the fingerprint image when the number of times exceeds a preset number of times.

6. The method according to claim 5 , further comprising:
after authenticating the user by the microprocessor according to the fingerprint image, when the number of times the authentication fails reaches a preset number of times, taking measures of an alarm and/or a lock on the vehicle.

7. The method according to claim 2 , further comprising:
after authenticating the user, by the microprocessor according to the fingerprint image:
upon the authentication succeeding, outputting the identity information of the user to the central control device of the vehicle; acquiring, by the central control device of the vehicle, a vehicle personalization parameter of the user according to the identity information of the user; and setting up, by the central control device of the vehicle, the vehicle according to the vehicle personalization parameter; and
upon the authentication failing, outputting information that the authentication fails to the central control device or outputting no information to the central control device.

8. The method according to claim 2 , further comprising:
after authenticating the user by the microprocessor according to the fingerprint image, upon the authentication succeeding and a brake signal is detected, notifying, by the microprocessor, the start controller of the vehicle to start the vehicle.

9. The method according to claim 1 , wherein the step of authenticating the user according to the fingerprint image and acquiring identity information of the user after the authentication succeeds comprises:
judging whether there is a fingerprint template matching the fingerprint image in respective pre-stored fingerprint templates, wherein a positive judgement indicates that the authentication succeeds; and
acquiring, according to correspondence between the pre-stored fingerprint templates and identity information, identity information corresponding to the fingerprint template that matches the fingerprint image, as the identity information of the user.

10. A system for controlling a vehicle, comprising:
a fingerprint sensor configured to collect a fingerprint image of a user;
a start controller configured to generate a command of enabling a fingerprint authentication function at least when detecting that a start button is pressed;
a fingerprint processing module configured to:
enter a fingerprint authentication mode after receiving a command of enabling a fingerprint authentication function from the start controller, in the fingerprint authentication mode authenticate the user according to the fingerprint image and acquire identity information of the user after the authentication succeeds; and
enter a fingerprint entry mode after receiving a command of enabling a fingerprint entry function; and in the fingerprint entry mode, generate a fingerprint template according to the fingerprint image, and establish correspondence between the fingerprint template and the identity information of the user that is received through a fingerprint entry assisting module;

a vehicle setting module configured to:
acquire a vehicle personalization parameter of the user according to the identity information of the user; and
set up the vehicle according to the vehicle personalization parameter; and

the fingerprint entry assisting module configured to:
when detecting a fingerprint entry request, disable a detection function of the start controller on whether the start button is pressed and send the command of enabling the fingerprint entry function to the fingerprint processing module.

11. The system according to claim 10 , wherein the fingerprint processing module is a microprocessor, and the fingerprint sensor and the microprocessor are integrated in a fingerprint chip.

12. The system according to claim 11 , wherein the fingerprint chip is mounted on a start button of the vehicle; and when the user's finger presses the start button, the finger faces a fingerprint collection surface of the fingerprint sensor; and
the microprocessor is further configured to notify a start controller of the vehicle to start the vehicle after the authentication succeeds.

13. The system according to claim 11 , wherein the fingerprint chip is further integrated with an infrared sensor; and
the microprocessor is further configured to perform live detection through the infrared sensor, and authenticate the user according to the fingerprint ima
