Description
Technical Field
The invention relates to the technical field of fuel cell automobiles, in particular to a remote upgrading control strategy for a fuel cell automobile.
Background
At present, software upgrading of a whole vehicle controller, a power battery controller, a motor controller and a fuel battery controller of a fuel battery vehicle on the market needs to be carried out on the vehicle, once software upgrading requirements appear, a large number of field maintenance personnel or vehicle owners need to go to a maintenance shop to be upgraded, upgrading cannot be completed rapidly, and meanwhile, a large amount of upgrading cost is caused.
Disclosure of Invention
In view of this, the embodiment of the present invention provides a remote upgrade control strategy for a fuel cell vehicle, which solves the disadvantage of software upgrade of the components of the power system of the existing fuel cell vehicle.
The embodiment of the invention discloses a remote upgrading control strategy of a fuel cell automobile, which comprises the following steps:
importing an upgrading task requirement, and verifying a software version and confirming an upgrading node after the task requirement is determined;
after the confirmation, pushing whether the user downloads the software upgrading package or not, and after the user agrees to download the upgrading software;
after downloading is finished, pushing an upgrading request and upgrading time through an application program, and entering an upgrading waiting mode after a user agrees to upgrade and sets starting time;
and after the upgrading time is up, upgrading is started, the VCU is awakened through the network, the VCU awakens the BMS, the MCU, the FCU and the HCU through the hard wires, meanwhile, each node feeds back the current software version and state, then, software version verification and upgrading condition determination are carried out, and remote upgrading is carried out after the determination is passed.
Furthermore, verification is carried out after upgrading, if upgrading is normal, upgrading is finished, and if upgrading fails, abnormal node upgrading is carried out again.
Further, after the abnormal node fails to be upgraded for 3 times, the upgrade is finished.
Further, after the upgrade is completed, the upgrade completion state is fed back and the user is pushed, and after the upgrade is completed, the controller enters the dormant state.
Furthermore, an upgrading task requirement is imported through the FOTA server platform, and after the task requirement is determined, the FOTA platform and the TBOX carry out software version verification and upgrading node confirmation.
Further, if the user does not agree to download the software upgrading package, the previous step is returned to.
Furthermore, after the upgrade time is up, upgrade is started, the FOTA platform wakes up the TBOX, and the TBOX wakes up the VCU through the network.
According to the embodiment of the invention, software upgrading can be carried out on each controller of the fuel cell automobile remotely, so that an engineer is prevented from going to the site or a user drives to a 4S store to upgrade the automobile, and a large amount of manpower, material resources and funds are saved.
Drawings
Fig. 1 is a flowchart illustrating a remote upgrade control policy operation according to an embodiment of the present invention.
FIG. 2 is a diagram of a system architecture for remote upgrade according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in the figure, the embodiment of the invention discloses a remote upgrading control strategy of a fuel cell automobile, and the method comprises the following steps:
importing an upgrading task requirement, and verifying a software version and confirming an upgrading node after the task requirement is determined;
after the confirmation, pushing whether the user downloads the software upgrading package or not, and after the user agrees to download the upgrading software;
after downloading is finished, pushing an upgrading request and upgrading time through an application program, and entering an upgrading waiting mode after a user agrees to upgrade and sets starting time; here the application is a cell phone app.
And after the upgrading time is up, upgrading is started, the VCU is awakened through the network, the VCU awakens the BMS, the MCU, the FCU and the HCU through the hard wires, meanwhile, each node feeds back the current software version and state, then, software version verification and upgrading condition determination are carried out, and remote upgrading is carried out after the determination is passed.
The invention imports the requirement of the upgrade task through the cloud platform, honors the client, upgrades according to the client intention, and awakens each specific controller through the VCU.
In an embodiment of the present invention, verification is performed after upgrading, if the upgrading is normal, the upgrading is completed, and if the upgrading fails, the abnormal node upgrading is performed again.
In an embodiment of the present invention, after the abnormal node fails to be upgraded for 3 times, the upgrade is finished.
By limiting the number of failed times of upgrading, if the number of failed times is too large, upgrading is not limited, other reasons may exist for the failure, and offline upgrading needs to be performed to find problems.
In an embodiment of the present invention, after the upgrade is completed, the upgrade completion status is fed back and the user is pushed, and after the upgrade is completed, the controller enters the sleep state. The sleep state is advantageous for reducing power consumption.
In an embodiment of the invention, an upgrading task requirement is imported through an FOTA server platform, and after the task requirement is determined, the FOTA platform and a TBOX perform software version verification and upgrading node confirmation.
In an embodiment of the present invention, if the user does not approve the downloading of the software upgrade package, the previous step is returned to.
In an embodiment of the invention, after the upgrade time is up, the upgrade is started, the FOTA platform wakes up the TBOX, and the TBOX wakes up the VCU through the network.
TBOX is communicated with VCU, BMS, MCU, FCU and HCU through ECAN bus.
The above description is only a preferred embodiment of the present invention, but other driving mechanisms including, but not limited to, motor driving and other driving sources are not intended to limit the present invention, and any modifications, equivalents and the like within the spirit and principle of the present invention should be included in the protection scope of the present invention.
