Abstract

A method and a device for controlling vehicle charging, a program, a medium, and a vehicle is provided. The method by acquiring a current connection state of a telematics box in the vehicle and the server when a charging gun of a vehicle is determined in a connection state; and recording a first duration of the offline state when the current connection state is determined in an offline state, and controlling the vehicle charging according to the first duration. In this way, when it is determined that the current connection state is in the offline state, the vehicle charging can be controlled according to the duration of the offline state, which can effectively avoid the problem of charging failure due to network connection failure during the reservation charging process, the reliability of vehicle reservation charging is improved, and thus the vehicle user experience is effectively improved.

First claim

What is claimed is:

1. A method for controlling vehicle charging, applied to a server, the method comprising:
acquiring, through a head unit system, a current connection state of a telematics box in a vehicle and the server when a charging gun of the vehicle is determined in a connection state; and
recording, through a timer in the server, a first duration of an offline state when the current connection state is determined in the offline state, and controlling, through a hybrid control unit, the vehicle charging according to the first duration;
wherein the step of controlling the vehicle charging according to the first duration enables to complete a reservation charging process in a case that network connection failure of the vehicle.

2. The method according to claim 1 , wherein before the step of acquiring the current connection state of the telematics box in the vehicle and the server, further comprising:
acquiring a time for reservation using the vehicle through a terminal; and
determining a waiting duration from a start of charging according to the time for reservation using the vehicle;
wherein the step of controlling the vehicle charging according to the first duration comprises:
updating the waiting duration according to the first duration to generate a target waiting duration when the first duration is determined to be less than or equal to a preset duration threshold; and
sending the target waiting duration to the telematics box to control the vehicle charging when a timing duration of the telematics box reaches the target waiting duration.

3. The method according to claim 2 , wherein the step of updating the waiting duration according to the first duration to generate the target waiting duration comprises:
acquiring a first difference between the waiting duration and the first duration; and
determining the first difference as the target waiting duration.

4. The method according to claim 2 , wherein the step of determining the waiting duration from the start of charging according to the time for reservation using the vehicle comprises:
acquiring a preset advance charging duration and a power on duration required for fully charging of the vehicle;
acquiring a target sum value of the preset advance charging duration and the power on duration;
acquiring a second duration between a current time and the time for reservation using the vehicle;
determining a second difference between the second duration and the target sum value; and
determining the second difference as the waiting duration.

5. The method according to claim 2 , further comprising:
sending the waiting duration to the telematics box when the current connection state is determined in an online state, to control the vehicle charging when the timing duration of the telematics box reaches the waiting duration.

6. The method according to claim 2 , wherein the step of controlling the vehicle charging according to the first duration comprises:
controlling the vehicle charging when the first duration is determined to be greater than the preset duration threshold.

7. A device for controlling vehicle charging, applied to a server, and comprising:
one or more processors and a storage device; and
the storage device stores a computer program which, when executed by the processor, performs operations comprising:
acquiring, through a head unit system, a current connection state of a telematics box in a vehicle and the server when a charging gun of the vehicle is determined in a connection state; and
recording, through a timer in the server, a first duration of an offline state when the current connection state is determined in the offline state, and controlling, through a hybrid control unit, the vehicle charging according to the first duration;
wherein the step of controlling the vehicle charging according to the first duration enables to complete a reservation charging process in a case that network connection failure of the vehicle.

8. The device according to claim 7 , wherein the operation of the device comprises:
acquiring a time for reservation using the vehicle through a terminal; and
determining a waiting duration from a start of charging according to the time for reservation using the vehicle;
the hybrid control unit is further configured to performs operations:
updating the waiting duration according to the first duration to generate a target waiting duration when the first duration is determined to be less than or equal to a preset duration threshold; and
sending the target waiting duration to the telematics box, to control the vehicle charging when a timing duration of the telematics box reaches the target waiting duration.

9. The device according to claim 8 , wherein the hybrid control unit is further configured to performs operations:
acquiring a first difference between the waiting duration and the first duration; and
determining the first difference as the target waiting duration.

10. The device according to claim 8 , wherein the hybrid control unit is further configured to performs operations:
acquiring a preset advance charging duration and a power on duration required for fully charging of the vehicle;
acquiring a target sum value of the preset advance charging duration and the power on duration;
acquiring a second duration between a current time and the time for reservation using the vehicle;
determining a second difference between the second duration and the target sum value; and
determining the second difference as the waiting duration.

11. The device according to claim 8 , wherein the operations of the device comprise:
sending the waiting duration to the telematics box when the current connection state is determined in an online state, to control the vehicle charging when the timing duration of the telematics box reaches the waiting duration.

12. The device according to claim 8 , wherein the hybrid control unit is further configured for:
controlling the vehicle charging when the first duration is determined to be greater than the preset duration threshold.

13. A vehicle, comprising a device for controlling vehicle charging, wherein the device is applied to a server, and comprising:
one or more processors and a storage device; and
the storage device stores a computer program which, when executed by the processor, performs operations comprising:
acquiring, through a head unit system, a current connection state of a telematics box in a vehicle and the server when a charging gun of the vehicle is determined in a connection state; and
recording, through a timer in the server, a first duration of an offline state when the current connection state is determined in the offline state, and controlling, through a hybrid control unit, the vehicle charging according to the first duration;
wherein the step of controlling the vehicle charging according to the first duration enables to complete a reservation charging process in a case that network connection failure of the vehicle.

14. A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores a computer-readable code, and when the computer-readable code is executed, to perform:
acquiring, through a head unit system, a current connection state of a telematics box in a vehicle and the server when a charging gun of the vehicle is determined in a connection state; and
