Currently, remote program upgrades are generally performed after the vehicle is powered on next time, but this solution requires the driver to wait for the program upgrade to be completed before driving. Therefore, the existing technology also proposes a solution in which the battery is used to power the program upgrade of the parts after the driver turns off the power of the entire vehicle, but this solution has the risk of insufficient battery power.

[0003] In this regard, the prior art provides a remote upgrade method for an in-vehicle system, which obtains the upgrade power required for the upgrade through an upgrade package, obtains the remaining power of the vehicle battery through the battery voltage, battery temperature and a preset power curve, and only when the remaining power of the vehicle battery is greater than the upgrade power will the program be upgraded, thereby avoiding the situation where the battery power is insufficient. However, the problem is that when the remaining power of the battery does not meet the upgrade power, the upgrade will be terminated, and the program upgrade needs to be attempted again after the vehicle is powered off next time. If the upgrade power required for the program upgrade is large, the remaining power of the battery will also not meet the upgrade power, which easily leads to the failure of the program upgrade.

[0054] Embodiment 1

[0055] When upgrading the program of vehicle parts, there is a risk of insufficient battery power. In this regard, the prior art provides a remote upgrade method for an on-board system, which obtains the upgrade power required for the upgrade through an upgrade package, and obtains the remaining power of the vehicle battery through the battery voltage, battery temperature and a preset power curve. The program upgrade will only be performed when the remaining power of the vehicle battery is greater than the upgrade power, thereby avoiding the situation of insufficient battery power. However, the problem is that when the remaining power of the battery does not meet the upgrade power, the upgrade will be terminated, and it is still necessary to try the program upgrade again after the vehicle is powered off next time. If the upgrade power required for the program upgrade is large, there is also a situation where the remaining power of the battery does not meet the upgrade power, which easily leads to the failure of the program upgrade.

[0056] In this regard, this embodiment provides a vehicle remote upgrade control method to solve the problem that the prior art will terminate the upgrade when the remaining battery power does not meet the upgrade power, and it is still necessary to attempt the program upgrade again after the vehicle is powered off next time, which is likely to cause the program upgrade to fail. The method can be used in the field of vehicle technology.

[0057] The vehicle remote upgrade control method may be executed by a vehicle remote upgrade control device, and the vehicle remote upgrade control device may be implemented by software and / or hardware and integrated in a vehicle.

[0058] Reference Figure 1 , the vehicle remote upgrade control method includes the following steps.

[0059] S100: Confirm that there are parts that need to be upgraded.

[0060] The components to be upgraded may be power systems such as engines or motors, or equipment such as on-board computers.

[0061] S140: Perform program upgrade.

[0062] Specifically, the Internet of Vehicles platform divides the upgrade program into packages. After the vehicle receives one program upgrade package, the Internet of Vehicles platform sends the next program upgrade package.

[0063] The vehicle remote upgrade control method further includes, after step S100:

[0064] S110: Obtain the remaining power of the battery and the expected power consumption of the program upgrade.

[0065] The remaining power of the battery can be obtained through the battery management system, and the expected power consumption of the program upgrade can be determined according to the size of the program upgrade package.

[0066] S120: Compare the remaining power of the battery with the expected power consumption.

[0067] If the remaining power of the battery is less than the expected power consumption, step S130 is executed.

[0068] S130: Charge the battery.

[0069] If the remaining battery power is less than the expected power consumption, it means that the remaining battery power is insufficient to meet the needs of the program upgrade. At this time, the battery is charged so that the remaining battery power can meet the needs of the program upgrade. There is no need to wait until the next time the vehicle is powered off to attempt the program upgrade, thereby avoiding program upgrade failure.

[0070] Optionally, step S130 includes: obtaining an expected charging time, charging the battery, and stopping charging after the expected time.

[0071] Wherein, obtaining the expected charging time includes: obtaining the difference between the expected power consumption and the remaining power of the battery, and obtaining the charging power; and obtaining the expected time based on the difference and the charging power. Specifically, the expected time can be obtained by dividing the difference between the expected power consumption and the remaining power of the battery by the charging power.

[0072] Optionally, the battery is connected to a DC-DC controller, and the DC-DC controller is connected to a vehicle power source. Charging the battery and stopping charging after an expected time includes: turning on the DC-DC controller so that the vehicle power source charges the battery, and turning off the DC-DC controller after an expected time, thereby controlling the vehicle power source to charge or stop charging the battery through the DC-DC controller, wherein the vehicle power source can be an engine or a motor.

[0073] In addition, in step S120, if the remaining power is not less than the expected power consumption, no operation may be performed, or the following steps may be performed: determining to stop charging the battery.

[0074] In this embodiment, step S110 and step S140 are performed synchronously, that is, the program upgrade and the acquisition of the remaining power of the battery and the expected power consumption of the program upgrade are performed synchronously. Among them, step S110 and step S140 are both performed after the driver turns off the engine and turns off the power, and the vehicle is powered off.

[0075] In other embodiments, step S110 and step S140 may not be executed synchronously, but step S110-step S130 are executed first, and after completing step S130, step S140 is executed; or, in step S120, if the remaining power is not less than the expected power consumption, step S140 is executed.

[0076] Embodiment 2

[0077] This embodiment provides a vehicle remote upgrade control method, which is specific based on the above embodiment 1. Figure 2 , the vehicle remote upgrade control method includes the following steps.

[0078] S200: Confirm that there are parts that need to be upgraded.

[0079] S210: Obtain the remaining power of the battery and the expected power consumption of the program upgrade.

[0080] S220: Compare the remaining power of the battery with the expected power consumption.

[0081] If the remaining power of the battery is less than the expected power consumption, step S230 is executed.

[0082] S230: Charge the battery.

[0083] Optionally, after completing execution of step S230, return to step S210.

[0084] The vehicle remote upgrade control method further includes the following steps, which are located after step S200 and are executed synchronously with step S210:

[0085] S240: Perform program upgrade.

[0086] S250: Determine whether the program upgrade is successful.

[0087] If the program upgrade is successful, the execution of the vehicle remote upgrade control method ends.

[0088] If the program upgrade fails, execute step S260.

[0089] S260: Accumulate the number of program upgrade failures and determine whether the number of program upgrade failures reaches a preset number.

[0090] If the number of program upgrade failures reaches a preset number, step S270 is executed.

[0091] If the number of program upgrade failures does not reach the preset number, step S280 is executed.

[0092] S270: Send an upgrade failure signal to the Internet of Vehicles platform.

[0093] Optionally, after completing step S270, the execution of the vehicle remote upgrade control method ends.

[0094] S280: Control the vehicle to power off and go into sleep mode.

[0095] S290: The vehicle starts and returns to step S240.

[0096] In this embodiment, the remaining battery power and the expected power consumption of the program upgrade are returned to obtain, and the program upgrade is performed, that is, step S210 and step S240 are executed simultaneously. While the program is being upgraded, the remaining battery power and the expected power consumption of the program upgrade are obtained again, and subsequent steps are executed.

[0097] In step S290, the vehicle waits for the driver to start the vehicle next time, and executes steps S210 and S240 after the vehicle is powered off again.
