Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The method for upgrading the controller provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The cloud 102 communicates with a vehicle-mounted terminal 104 of a vehicle to be upgraded through a network. The cloud 102 issues an upgrade task, and the vehicle-mounted terminal 104 acquires an upgrade software package corresponding to the upgrade task, a controller type of a controller to be upgraded and estimated upgrade duration; the vehicle-mounted terminal 104 acquires the type of the vehicle to be upgraded, to which the controller to be upgraded belongs, and the current electric quantity of a battery of a storage battery in the vehicle to be upgraded; determining the estimated remaining capacity of the storage battery under the upgrading task according to the type of the controller, the estimated upgrading duration, the type of the vehicle and the current capacity of the battery; and if the estimated remaining electric quantity is larger than the preset starting storage capacity of the vehicle to be upgraded, upgrading the controller to be upgraded through an upgrading software package.
In an exemplary embodiment, as shown in fig. 2, a controller upgrade method is provided, and an example of application of the method to the in-vehicle terminal 104 in fig. 1 is described, including the following steps S201 to S204. Wherein:
s201, acquiring an upgrade software package corresponding to an upgrade task, a controller type of a controller to be upgraded and an estimated upgrade duration.
The upgrade task may be a task for upgrading a controller to be upgraded in a vehicle to be upgraded. The upgrade package may be a package for upgrading a controller to be upgraded. The controller types include a tri-electric controller and a non-tri-electric controller, and by way of example, the tri-electric controller may include a micro control unit (Microcontroller Unit, MCU), a battery management system (Battery Management System, BMS), a direct current-to-direct current Converter (DCDC), and the like. The estimated upgrade duration may be an estimated duration of upgrading the controller to be upgraded, and optionally, the estimated upgrade duration may be determined according to a data size of the upgrade software package.
Optionally, the vehicle-mounted terminal acquires an upgrade task from the cloud, displays the upgrade task to a user through a display interface of the vehicle-mounted terminal, and analyzes the upgrade task after detecting the confirmation upgrade operation for the upgrade task, so as to determine to obtain an upgrade software package corresponding to the upgrade task, a controller type of a controller to be upgraded and estimated upgrade duration.
S202, acquiring the type of the vehicle to be upgraded, to which the controller to be upgraded belongs, and the current electric quantity of the battery of the storage battery in the vehicle to be upgraded.
Vehicle types include electric vehicles and non-electric vehicles, among others. Among them, an electric vehicle is understood as a vehicle that powers the vehicle running by electric energy.
Optionally, the vehicle-mounted terminal determines the type of the vehicle corresponding to the vehicle to be upgraded, to which the controller to be upgraded belongs, and obtains the current electric quantity of the battery of the storage battery in the vehicle to be upgraded at the current moment. It should be noted that the sequence of acquiring different data is not limited in this application.
And S203, determining the estimated residual capacity of the storage battery under the upgrading task according to the type of the controller, the estimated upgrading time length, the type of the vehicle and the current capacity of the battery.
Optionally, the vehicle-mounted terminal may input the obtained controller type, the estimated upgrading duration, the vehicle type and the current electric quantity of the battery into a pre-trained electric quantity estimation model, where the electric quantity estimation model may select an electric quantity estimation sub-model meeting the vehicle type and the controller type according to the vehicle type and the controller type, and determine, through the electric quantity estimation sub-model, an estimated remaining electric quantity of the storage battery under the upgrading task according to the estimated upgrading duration and the current electric quantity of the battery.
And S204, if the estimated remaining electric quantity is larger than the preset starting storage capacity of the vehicle to be upgraded, upgrading the controller to be upgraded through an upgrading software package.
The preset starting storage capacity guarantees the electric quantity of the vehicle to be upgraded which can be started. The preset starting charge capacity comprises a first preset starting charge capacity (50%) of which the battery supports the starting of the vehicle to be upgraded and a second preset starting charge capacity (40%) of which the battery does not support the starting of the vehicle to be upgraded; the first preset starting charge capacity is greater than the second preset starting charge capacity.
Optionally, if the estimated remaining power is greater than the preset starting power storage capacity of the vehicle to be upgraded, the power of the storage battery after the upgrading task is finished is proved to still ensure the normal starting of the vehicle to be upgraded, so that the upgrading processing of the controller to be upgraded can be performed through the upgrading software package.
It should be noted that, since the vehicle types of the vehicle to be upgraded include electric vehicles and non-electric vehicles, in which the electric vehicles require the battery to supply the start energy to the engine, and the non-electric vehicles do not require the battery to supply the start energy to the engine, different preset start-up electric storage amounts may be set for different vehicle types. Optionally, according to the type of the vehicle, a preset starting charge capacity corresponding to the vehicle to be upgraded is determined. Specifically, the vehicle-mounted terminal determines a vehicle type of the vehicle to be upgraded, selects a starting charge storage amount corresponding to the vehicle type, and takes the starting charge storage amount as a preset starting charge storage amount. Further, if the vehicle type is an electric vehicle, the preset starting charge capacity corresponding to the vehicle to be upgraded is a first preset starting charge capacity; if the vehicle type is a non-electric vehicle, the preset starting charge capacity corresponding to the vehicle to be upgraded is the second preset starting charge capacity. Specifically, if the vehicle type is an electric vehicle, it is proved that the electric vehicle needs to provide starting energy for the engine by the storage battery, so that a larger starting storage capacity is needed, and the first preset starting storage capacity is used as the preset starting storage capacity; if the vehicle type is a non-electric vehicle, the electric vehicle is proved to not need a storage battery to provide starting energy for the engine, so that a larger starting storage battery is not needed, and the second preset starting storage battery is taken as the preset starting storage battery. The advantage of this arrangement is that a more suitable preset starting charge capacity is provided for different vehicle types to further improve the upgrade success rate of the controller to be upgraded.
It should be noted that, if the estimated remaining power is smaller than the preset starting power storage capacity of the vehicle to be upgraded, it proves that there is a possibility that the upgrade task cannot be successfully completed or that the vehicle is started abnormally after the upgrade task is completed, so that the controller to be upgraded in the vehicle to be upgraded cannot be upgraded in order to ensure the subsequent normal starting of the vehicle, and therefore, the embodiment needs to end the upgrade task and prompt the user that the upgrade task cannot be completed.
According to the controller upgrading method, an upgrading software package corresponding to an upgrading task, the controller type of the controller to be upgraded and the estimated upgrading duration are obtained; acquiring the type of a vehicle to be upgraded, to which a controller to be upgraded belongs, and the current electric quantity of a battery of a storage battery in the vehicle to be upgraded; determining the estimated remaining capacity of the storage battery under the upgrading task according to the type of the controller, the estimated upgrading duration, the type of the vehicle and the current capacity of the battery; and if the estimated remaining electric quantity is larger than the preset starting storage capacity of the vehicle to be upgraded, upgrading the controller to be upgraded through an upgrading software package. Compared with the prior art, the method and the device for upgrading the vehicle controller only determine whether the vehicle controller can be upgraded by judging the size relation between the current electric quantity of the battery and the preset minimum electric quantity of the battery.
FIG. 3 is a flow diagram of an upgrade controller, according to one embodiment. The embodiment provides an optional mode for upgrading the controller, which comprises the following steps:
s301 acquires a controller type and a vehicle type.
S302 determines whether a battery remaining power estimation condition for estimating a remaining power is satisfied according to the controller type and the vehicle type.
The battery remaining power estimation condition may be a condition for judging whether to calculate the estimated remaining power.
One alternative implementation manner may be to determine whether the controller type belongs to a preset controller type, and determine whether the vehicle type belongs to a preset vehicle type at the same time, if the controller type belongs to the preset controller type and the vehicle type belongs to the preset vehicle type at the same time, consider that a battery residual power estimation condition for estimating the residual power is not satisfied; and otherwise, the battery residual capacity estimation condition of the estimated residual capacity is considered to be satisfied.
Another alternative implementation manner may be that if the vehicle type is an electric vehicle and the controller type is a non-three-electric controller, determining whether the current electric quantity of the power battery of the electric vehicle is greater than a preset electric quantity threshold; if the current electric quantity of the power battery is larger than a preset electric quantity threshold value, charging the storage battery through the power battery, and determining a charging result; if the charging result is that the charging is successful, the battery remaining capacity estimation condition for estimating the remaining capacity is not satisfied.
Specifically, whether the vehicle type of the vehicle to be upgraded is an electric vehicle is determined, whether the controller type of the controller to be upgraded is a non-three electric controller is determined under the condition that the vehicle type is the electric vehicle, when the vehicle type is the electric vehicle and the controller type is the non-three electric controller, whether the current electric quantity of a power battery of the electric vehicle is larger than a preset electric quantity threshold value is further judged, if the current electric quantity of the power battery is larger than the preset electric quantity threshold value, the power battery in the vehicle to be upgraded can be proved to be charged for the storage battery at the moment, therefore, high-voltage power-on operation is performed through the power battery, charging processing is performed for the storage battery, and whether charging is successful is further determined, and when charging is successful, the problem that the storage battery is not in power shortage at the moment is proved, so that calculation for estimating the residual electric quantity is not needed, and therefore, the battery residual electric quantity estimating condition for estimating the residual electric quantity is not met. It should be noted that, in this embodiment, only when the vehicle type is an electric vehicle, the controller type is a non-three-electric controller, the current electric quantity of the power battery is greater than a preset electric quantity threshold, and the charging result is that the charging is successful, it can be determined that the to-be-upgraded controller in the vehicle to be upgraded at this time does not meet the battery remaining quantity estimation condition for estimating the remaining quantity; if any of the above conditions is not satisfied, the to-be-upgraded controller satisfies the battery remaining power estimation condition for estimating the remaining power.
The method has the advantages that various logic judgment is set to determine that the battery residual capacity estimation condition of the estimated residual capacity is not met, the upgrading task can be successfully completed, meanwhile, calculation of the estimated residual capacity is reduced, and the processing efficiency of the vehicle-mounted terminal for the upgrading task is improved.
And S303, if the battery remaining capacity estimation condition is met, determining the estimated remaining capacity of the storage battery according to the estimated upgrading time length and the current capacity of the storage battery.
One optional implementation manner may be that if the battery remaining capacity estimation condition is met, the estimated upgrading time length and the current electric capacity of the storage battery are input into a preset remaining capacity estimation model, and the remaining capacity estimation model outputs the estimated remaining capacity of the storage battery.
Another alternative implementation manner may be to determine the estimated power consumption corresponding to the upgrade task according to the estimated upgrade duration, the preset battery current amount and the preset total battery capacity; and determining the estimated remaining capacity of the storage battery according to the estimated power consumption and the current storage capacity of the battery.
Specifically, according to the estimated upgrading time length, the preset battery current amount and the preset battery total capacity, the estimated power consumption corresponding to the upgrading task is calculated and obtained through the following formula (1-1), and further according to the estimated power consumption and the current storage capacity of the battery, the estimated residual capacity of the storage battery is calculated and obtained through the following formula (1-2). The method has the advantages that the estimated power consumption is calculated preferentially, and the estimated residual capacity of the storage battery can be calculated more accurately and reasonably according to the estimated power consumption and the current storage capacity of the battery.
f＝I×OTA Time ÷M÷(C*0.8) (1-1)
Wherein f represents estimated power consumption, I represents preset battery current amount (i.e. current value of the storage battery), OTA Time Characterizing the doubling of the estimated upgrade duration (i.e., OTA Time ＝2×OTA Packagetime ，OTA Packagetime Characterizing the estimated upgrade duration), M characterizes 3600 seconds (i.e., one hour), and C characterizes the preset total battery capacity (i.e., the capacity of the battery).
SOC Gu ＝SOC-f (1-2)
Wherein SOC is GU The estimated remaining capacity of the storage battery is represented, the SOC represents the current storage capacity of the storage battery, and f represents the estimated power consumption.
And S304, if the estimated remaining electric quantity is larger than the preset starting storage capacity of the vehicle to be upgraded, upgrading the controller to be upgraded through an upgrading software package.
And S305, if the battery residual capacity estimation condition for estimating the residual capacity is not met, carrying out upgrading treatment on the controller to be upgraded through an upgrading software package.
Optionally, if the battery remaining power estimation condition for estimating the remaining power is not met, it is proved that the power of the electric battery in the electric vehicle is sufficient to support charging of the storage battery at this time, smooth completion of the upgrading task is ensured, and the vehicle can be started normally after the upgrading task is completed, so that the problem of insufficient power of the storage battery is not required to be considered, and therefore, the controller to be upgraded can be directly upgraded through an upgrading software package.
According to the controller upgrading method, the controller type and the vehicle type are obtained, whether the battery residual capacity estimation condition of the estimated residual capacity is met is determined according to the controller type and the vehicle type, if the battery residual capacity estimation condition is met, the estimated residual capacity of the storage battery is determined according to the estimated upgrading duration and the current electric capacity of the storage battery, and if the estimated residual capacity is larger than the preset starting storage capacity of the vehicle to be upgraded, upgrading processing is carried out on the controller to be upgraded through an upgrading software package. In the embodiment, characteristics of different vehicles to be upgraded and controllers to be upgraded are comprehensively considered, whether the battery residual capacity estimation condition is met is determined, if the battery residual capacity estimation condition is met, the estimated residual capacity is calculated, and whether the vehicle is upgraded is further determined according to the estimated residual capacity; if the battery remaining capacity estimation condition is not met, the fact that the power battery is charging the storage battery at the moment is proved, so that the controller to be upgraded can be directly upgraded through the upgrading software package, and the upgrading success rate of the controller to be upgraded is further improved.
In one embodiment, this embodiment provides an alternative way for upgrading the controller, and the method is applied to the vehicle-mounted terminal for illustration. As shown in fig. 4, the method comprises the steps of:
S401, acquiring an upgrade software package corresponding to an upgrade task, a controller type of a controller to be upgraded and an estimated upgrade duration.
S402, acquiring the type of the vehicle to be upgraded, to which the controller to be upgraded belongs, and the current electric quantity of the battery of the storage battery in the vehicle to be upgraded.
S403, determining whether the vehicle type of the vehicle to be upgraded is an electric vehicle, and whether the controller type of the controller to be upgraded is a non-three-electric controller, if so, executing step S404, and if not, executing step S406.
S404, if the vehicle type is an electric vehicle and the controller type is a non-three-electric controller, determining whether the current electric quantity of a power battery of the electric vehicle is greater than a preset electric quantity threshold, if so, executing a step S405, and if not, executing a step S406.
And S405, if the current electric quantity of the power battery is larger than a preset electric quantity threshold value, the power battery is used for carrying out charging treatment on the storage battery, whether the charging result is successful or not is determined, if so, the step S410 is executed, and if not, the step S406 is executed.
S406, determining the estimated power consumption corresponding to the upgrading task according to the estimated upgrading time length, the preset battery current amount and the preset battery total capacity.
S407 determines an estimated remaining capacity of the battery based on the estimated power consumption and the current charge capacity of the battery.
S408, determining the corresponding preset starting storage capacity of the vehicle to be upgraded according to the type of the vehicle.
Optionally, if the vehicle type is an electric vehicle, the preset starting charge capacity corresponding to the vehicle to be upgraded is a first preset starting charge capacity; if the vehicle type is a non-electric vehicle, the preset starting storage capacity corresponding to the vehicle to be upgraded is a second preset starting storage capacity; the method comprises the steps that a preset starting storage capacity comprises a first preset starting storage capacity for supporting the starting of a vehicle to be upgraded by a battery and a second preset starting storage capacity for not supporting the starting of the vehicle to be upgraded by the battery; the first preset starting charge capacity is greater than the second preset starting charge capacity.
S409 determines whether the estimated remaining power is greater than a preset starting charge capacity of the vehicle to be upgraded, if so, step S410 is executed, and if not, step S411 is executed.
S410, upgrading the controller to be upgraded through an upgrading software package.
S411, if the estimated remaining power is smaller than the preset starting storage capacity of the vehicle to be upgraded, ending the upgrading task.
For example, it is assumed that an upgrade task a and an upgrade task B exist, where a controller a to be upgraded corresponding to the upgrade task a is a three-electric related controller, and the upgrade time a is estimated to be 600s; the controller B to be upgraded corresponding to the upgrading task B is a non-three-electric-related controller, and the upgrading time B is estimated to be 1200s. The preset battery current amount of the storage battery is 30A, and the total preset battery capacity is 80MAh.
