The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The following explains an application scenario provided by an embodiment of the present invention: the scheme provided by the embodiment of the invention relates to the OTA function of a vehicle. The OTA function of the whole vehicle is generally realized by realizing remote management and upgrading of vehicle software through a mobile communication interface, and specifically, the OTA function can obtain more functions, improve the vehicle performance and the like by online detection of the Internet, version matching, downloading of a new code to the local, and then executing programs such as installation, verification and the like.
When the OTA function is used for upgrading each part of the vehicle, the storage battery on the vehicle is generally used for supplying power, but most of the storage battery is 12V, and the battery capacity is small. The use of battery power when upgrading results in a power shortage risk, so most users will try to reduce the upgrade.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present invention. As shown in fig. 1, when a vehicle needs to be upgraded, an upgrade task is issued by a cloud, a vehicle end main control in the vehicle determines the electric quantity of a storage battery, wherein a gateway provides a storage battery electric quantity message, a storage battery electric quantity sensor collects the stored electric quantity in real time, and if the electric quantity of the storage battery meets the electric quantity requirement when an upgrade module is upgraded, the upgrade module is powered on and upgraded until the upgrade module is finished; and if the electric quantity of the storage battery does not meet the electric quantity requirement when the upgrading module is upgraded, quitting the upgrading.
In some technologies, a precondition is set, and a voltage and electric quantity threshold value entering upgrading is judged, but because the battery performance is greatly influenced by service life and temperature, the method for judging the access value is not accurate enough, the electric quantity in the upgrading process cannot be ensured to be sufficient, and after the upgrading is finished, whether the electric quantity of a storage battery can meet the requirement of starting a vehicle or not exists potential safety hazard.

Therefore, the embodiment of the invention provides a vehicle upgrading method, which comprises the steps of firstly judging whether a low-voltage module exists in an upgrading module, if the low-voltage module is powered by a power battery and is upgraded, and if a high-voltage module exists in the upgrading module, the high-voltage module is powered by a storage battery and is upgraded after the upgrading is finished, so that the electric quantity pressure of the storage battery can be greatly reduced, the electric quantity shortage of the storage battery caused by OTA (over the air) upgrading is avoided, the power shortage risk is reduced, and the user experience is improved.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The features of the embodiments and examples described below may be combined with each other without conflict between the embodiments.
Fig. 2 is a schematic flow chart of a vehicle upgrading method according to an embodiment of the present invention. As shown in fig. 2, the method in this embodiment may include:
step 201, judging whether a low-voltage module exists in the modules to be upgraded of the vehicle.
The low-voltage Module may be a low-voltage system in a vehicle, such as a vehicle ignition switch and a tower iron, a BCM (Body Controller Module), a lighting system, an air conditioner control system, and the like.
When the OTA upgrading task is issued at the cloud end, the vehicle is in an un-started state, and the vehicle end main control judges whether a low-voltage module exists in the module to be upgraded or not. The OTA upgrade task can indicate which modules in the vehicle need to be upgraded.
And 202, if the low-voltage module exists, supplying power to the low-voltage module through a power battery and upgrading the low-voltage module.
Optionally, the low-voltage module and the power battery may be connected through a DC/DC converter. When the low-voltage module exists in the upgrading module, the vehicle-end main control applies for high-voltage power supply, the DC/DC converter is pulled up, the high-voltage direct current of the power battery is converted into the low-voltage direct current to supply power to the low-voltage module, and the low-voltage module is upgraded. Or the storage battery and the power battery can be connected through a DC/DC converter, and the DC/DC converter converts the high-voltage direct current of the power battery into low-voltage direct current to be output to the storage battery and supply power to the low-voltage module.
Under other optional conditions, the condition that only the storage battery supplies power is eliminated, and the power battery is selected to supply power for the low-voltage module, so that the power loss of the storage battery is reduced.
If the low-voltage module does not exist in the module to be upgraded, the step 203 of supplying power to the high-voltage module through the storage battery and upgrading the high-voltage module can be directly executed.
And 203, after the low-voltage module is upgraded, if the module to be upgraded also comprises a high-voltage module, supplying power to the high-voltage module through a storage battery and upgrading the high-voltage module.
The high voltage module may be a high voltage system of the electric vehicle, such as a battery manager, a power battery, a driving motor, a high voltage distribution box, an electric compressor, DC/DC, a PTC (Positive Temperature Coefficient), a high voltage wire harness, and the like.
After the low-voltage module is upgraded, judging whether a high-voltage module exists in the upgrading module, and if the high-voltage module does not exist, finishing the upgrading; and if the high-voltage module exists, the storage battery is used for supplying power to the high-voltage module and upgrading the high-voltage module.
When the high-voltage module is upgraded, the high-voltage module may be a module for controlling the power battery, so that in the embodiment of the invention, when the high-voltage module is upgraded, the high-voltage module is powered by the storage battery instead of the power battery, the high-voltage module does not need to execute a battery control function while being upgraded, the upgrading stability is improved, and the overall unbalance of the system is avoided. For example, in the process of upgrading the battery manager, the battery manager is in a shutdown state, cannot issue an instruction to the power battery, and needs to upgrade the power battery correspondingly, and at the moment, the storage battery can be selected to supply power to the high-voltage module and upgrade the high-voltage module. The vehicle upgrading method that this embodiment provided judges whether there is the low pressure module in the module that the vehicle waited to upgrade, if exist, then does through power battery the low pressure module power supply and carry out the upgrading of low pressure module after the low pressure module upgrading is accomplished, if the module of waiting to upgrade still includes high pressure module, then do through the battery the high pressure module power supply and carry out the upgrading of high pressure module is different according to the distribution of upgrading module, selects suitable power mode to upgrade, reduces the electric quantity pressure of battery by a wide margin, avoids the not enough problem of battery electric quantity that leads to because of OTA upgrading, reduces insufficient electric risk.
On the basis of the technical solution provided in the above embodiment, optionally, if the module to be upgraded further includes a high voltage module, the battery supplies power to the high voltage module and upgrades the high voltage module, including:
if the module to be upgraded also comprises a high-voltage module, judging whether the electric quantity of the storage battery meets the electric quantity condition required by upgrading of the high-voltage module; and if so, the storage battery is utilized to supply power to the high-voltage module and upgrade the high-voltage module.
When the upgrading module has a high-voltage module, whether the electric quantity of the storage battery can meet the upgrading requirement of the high-voltage module is judged, if the electric quantity of the storage battery meets the electric quantity required by the upgrading of the high-voltage module, the storage battery can be used for supplying power to the high-voltage module and upgrading the high-voltage module.
When the battery electric quantity satisfies senior module upgrading, usable battery carries out the power supply upgrading for senior module, satisfies senior module upgrading to the battery electric quantity and judges, avoids the electric quantity not enough, the upgrading module in the upgrading in-process condition of failure midway.
Optionally, the method further includes: if the electric quantity of the storage battery does not meet the condition of supplying power to the high-voltage module, the power battery is used for supplementing power to the storage battery; if the electric quantity of the storage battery is detected to meet the electric quantity condition required by the upgrading of the high-voltage module, stopping power supplement; and supplying power to the high-voltage module through the storage battery after power supplement, and upgrading the high-voltage module.
When the electric quantity of the storage battery cannot meet the electric quantity required by upgrading of the high-voltage module, the vehicle-end main control pulls a DC/DC converter between the power battery and the storage battery, high-voltage direct current of the power battery is converted into low-voltage direct current to supplement the electric quantity for the storage battery, electricity supplementing time can be set, after the specified electricity supplementing time is finished, the vehicle-end main control judges whether the electric quantity of the storage battery meets the requirement, if not, electricity supplementing of corresponding electricity supplementing time is continued until the electric quantity of the storage battery meets the required electric quantity required by upgrading of the high-voltage module. And when the electric quantity of the storage battery meets the requirement, the power supply loop is withdrawn, and the high-voltage module is supplied with power and is controlled to be upgraded.
Specifically, the electricity supplementing time can be set to be 10 minutes, when the electric quantity of the storage battery is not satisfied as the electric quantity upgraded by the high-voltage module, the power battery is used for supplementing electricity for the storage battery for 10 minutes, after the electricity supplementing is finished, the electric quantity of the storage battery is judged by the vehicle control main terminal, if the electric quantity of the storage battery is satisfied as the electric quantity upgraded by the high-voltage module, the electricity supplementing is quitted, and the storage battery is used for supplying power for the high-voltage module and upgrading the high-voltage module.
Or in the electricity supplementing process, whether the electric quantity of the storage battery meets the requirement or not can be judged in real time, the electricity supplementing is quitted and the upgrading is carried out when the requirement is met, and the upgrading efficiency is improved.
When the electric quantity of the storage battery does not meet the electric quantity of the high-voltage module for upgrading, the power battery supplies power for the storage battery until the electric quantity of the storage battery meets the electric quantity of the high-voltage module for upgrading, so that the high-voltage module can be guaranteed to have sufficient electric quantity supply in the upgrading process, and the success rate of upgrading the high-level module is improved.
Optionally, judging whether the electric quantity of the storage battery meets the electric quantity condition required by upgrading the high-voltage module includes:
determining the electric quantity required by upgrading each high-voltage module to be upgraded;
and judging whether the electric quantity of the storage battery meets the electric quantity condition required by the upgrading of the high-voltage module or not according to the electric quantity of the storage battery and the electric quantity required by the upgrading of each high-voltage module.
Optionally, it may be determined whether the electric quantity of the storage battery meets a sum of all electric quantities required by each high-voltage module to be upgraded. If the requirement is met, the high-voltage module is powered by the storage battery and upgraded, if the requirement is not met, the high-voltage module is powered by the power battery, and the high-voltage module to be upgraded is powered by the storage battery and upgraded until the electric quantity of the storage battery can meet all required electric quantities when the high-voltage module is upgraded.
In other alternative implementations, each module may also be sequentially and individually judged and upgraded. If the module to be upgraded further comprises a high-voltage module, the storage battery supplies power to the high-voltage module and upgrades the high-voltage module, and the method can be realized in the following mode: if the module to be upgraded also comprises a high-voltage module, respectively executing the following steps for each high-voltage module: judging whether the electric quantity of the storage battery meets the electric quantity condition required by the upgrading of the high-voltage module; if so, the storage battery is utilized to supply power to the high-voltage module and upgrade the high-voltage module; if the power supply voltage does not meet the requirement, the power battery is used for supplementing power to the storage battery until the electric quantity of the storage battery meets the electric quantity condition required by the upgrading of the high-voltage module, and the storage battery after power supplement supplies power to the high-voltage module and upgrades the high-voltage module.
Specifically, the electric quantity required by each high-voltage module to be upgraded in the upgrading process is determined, the electric quantity required by each high-voltage module is sequenced from low to high, when whether the electric quantity of the storage battery meets the electric quantity required by the high-voltage module during upgrading is judged, the electric quantity of the storage battery can be compared with the high-voltage module upgraded by the low electric quantity, if yes, the storage battery is used for supplying power to the high-voltage module and upgrading the high-voltage module, if not, the power battery is used for supplementing power to the storage battery, and the electric quantity of the storage battery meets the high-voltage module to be upgraded and is compared in sequence until all the high-voltage modules to be upgraded are upgraded.
For example, the amounts of power required when the high voltage module 1, the high voltage module 2, and the high voltage module 3 are upgraded are 1500C, 2000C, and 3000C, respectively. At this moment, the electric quantity of the storage battery is 1700C, the electric quantity of the storage battery and the electric quantity of the high-voltage module 1 are judged firstly to meet requirements, the high-voltage module 1 is powered and upgraded, 200C of the electric quantity of the storage battery is remained after the high-voltage module 1 is upgraded, the high-voltage module 2 cannot be upgraded, the storage battery needs to be subjected to electricity supplementing operation, the electric quantity of the storage battery is 6000C after electricity supplementing is finished, the electric quantity required when the high-voltage module 2 is upgraded can be met, and the electric quantity required when the high-voltage module 3 is upgraded is also met.
And the upgrade of part of the high-voltage modules can be allowed by the judgment respectively, and the upgraded high-voltage modules can assist in controlling the power battery to charge the storage battery, so that the control effect of the power battery is improved.
Through confirming required electric quantity when high-voltage module upgrades and comparing with the electric quantity of battery, before using battery electric quantity upgrading senior module, judge the electric quantity, mend the electricity when battery electric quantity is unsatisfied, mend the electricity and accomplish the back, continue the upgrading, reduce the condition that does not have electricity, insufficient electricity in the upgrading process to after the completion of upgrading, whole car can normally be gone up electrically.
