Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
An electric vehicle electricity management method according to an embodiment of the present invention is described below with reference to fig. 1 to 3.
Fig. 1 is a flowchart of an electric vehicle electricity management method according to an embodiment of the present invention, and as shown in fig. 1, the electric vehicle electricity management method according to the embodiment of the present invention includes at least steps S1-S3, each of which is described below.
And S1, the vehicle-mounted display terminal detects the trigger command of the power saving mode.
In the embodiment of the invention, the adjustment or setting of the power saving mode of the vehicle is realized through the vehicle-mounted display terminal, such as the vehicle-mounted PAD, the vehicle-mounted multimedia and the like.
Specifically, the vehicle-mounted display terminal may provide a display interface, as shown in fig. 2, which is a schematic view of a power saving mode display interface of the vehicle-mounted display terminal, where the vehicle-mounted display terminal receives a power saving state setting instruction of a user, provides a power saving setting option of the electrical equipment on the display interface, and generates preset power saving state information of the electrical equipment according to the power saving state input information of the user. The power saving setting options of each electric device are provided through a display interface, for example, fig. 2 includes whether a navigation system is turned on, the backlight brightness of multimedia, the gear position and the mode of an air conditioner, and the vehicle-mounted display terminal generates preset power saving state information of the electric device according to the power saving state input information of a user, and stores the preset power saving state information in a storage unit of the vehicle-mounted display terminal. Therefore, the user can select the power saving state information according to the options of the power saving state information provided by the vehicle-mounted display terminal, the situation that which electric equipment is not clear to set for power saving does not occur, and convenience is brought to the user. And the electric quantity of the vehicle battery does not need to be considered, and the power-saving setting can be carried out even if the electric quantity of the battery is high, so that the continuation of the journey mileage is favorably prolonged.
In some embodiments, the vehicle instrument module obtains the battery power information, and when the battery power is determined to be lower than the preset power threshold according to the battery power information, the vehicle instrument module sends a request for entering a power saving mode to the vehicle-mounted display terminal, and the vehicle-mounted device automatically sends a power saving request according to the battery power information, so that requirements for a driver can be reduced. Wherein, when the battery electric quantity is different, the mobile unit can provide different power saving modes, for example, 50% electric quantity and 30% electric quantity give different power saving suggestions, or, according to the driver's needs, give the driver more choices, can realize the power saving setting in advance simultaneously. Or self-learning can be carried out according to the electricity utilization habits of the driver to generate the corresponding power saving mode, or the power saving mode can be generated according to the driving mode and the scene, for example, the low power consumption of the air conditioner can be considered in summer, or the entertainment function is considered in advance, so that the vehicle-mounted system is more intelligent.
After receiving the request for entering the power saving mode, the vehicle-mounted display terminal provides selection information whether to enter the power saving mode on the display interface, for example, a yes/no selection frame for entering the power saving mode is popped up on the display interface, a user can select to enter the power saving mode or not, and when receiving a selection instruction for entering the power saving mode, the vehicle-mounted display terminal determines that a trigger instruction of the power saving mode is detected. In short, in the low battery state, a user operation may be guided by the in-vehicle display terminal to cause the vehicle to enter the power saving mode.
In other embodiments, the display interface of the in-vehicle display terminal is provided with a trigger unit of the power saving mode, for example, as shown in fig. 3, the display interface of the in-vehicle display terminal 04 often displays a shortcut key 15 of the power saving mode, and the in-vehicle display terminal determines that the trigger action of the power saving mode is detected when detecting the operation input of the trigger unit. In short, under the non-low-power state, the user can also realize that the vehicle enters the power saving mode by one key through the frequently-displayed trigger unit of the vehicle-mounted display terminal, namely, the user can actively trigger the vehicle to enter the power saving mode, and the vehicle enters the power saving mode by one key, so that the setting of a driver is facilitated.
And S2, the vehicle-mounted display terminal sends the preset power saving state information to the electric equipment control unit.
As described above, the user may preset the power saving state information through the power saving setting option provided by the vehicle-mounted display terminal, where the preset power saving state information is stored in the storage unit of the vehicle-mounted display terminal, or the vehicle-mounted display terminal prestores default power saving state information of each piece of electrical equipment. The power saving method and the power saving device have the advantages that user presetting is adopted, individual requirements of users can be met, the display interface provides options for user operation, the users can clearly set which functions are used for saving power, some unusual functions or devices can be prevented from being in a standby state, and power consumption is reduced.
Furthermore, in a low power state, when the vehicle-mounted display terminal receives a request of a power saving mode, the preset power saving state information can be sent to the corresponding electric equipment control unit; or, in a non-low power state, when the vehicle-mounted display terminal detects that the trigger unit of the power saving mode is triggered, the pre-stored preset power saving state information can be sent to the electric equipment control unit.
In an embodiment, the in-vehicle display terminal may transmit preset power saving state information to at least one of a navigation system, a screen backlight manager, a task manager and a gateway of the vehicle, wherein the preset power saving state information may be transmitted to at least one of an interface power supply, a shift controller, an instrument backlight adjustment module, an air conditioner controller, a seat function controller, a window controller and an energy feedback controller through the gateway.
For example, when a vehicle is driven in the dark, if the brightness of the navigation system or the screen backlight is high, the eyes of a user are easy to feel uncomfortable, especially, under the condition that the electric quantity of a battery is low, energy consumption is caused, the user can set the brightness of the navigation system and the screen backlight through a power saving mode, then the vehicle-mounted display terminal sends the set brightness value to the navigation system and the screen backlight manager, and the navigation system and the screen backlight manager adjust the navigation brightness and the screen backlight, so that the power saving mode is realized, and the discomfort of strong light to the eyes of the driver in the dark is also reduced.
For another example, when the battery power is lower than 30%, the output of the interface power supply and the backlight brightness of the vehicle-mounted device may be reduced to reduce power consumption, then the user may set the interface power supply and the related background brightness through the display interface of the vehicle-mounted display terminal, and then the vehicle-mounted display terminal sends the setting parameter to the screen backlight manager and the gateway, the screen backlight manager adjusts the screen background brightness, and the gateway sends the set instrument backlight parameter to the instrument backlight adjustment module, the instrument backlight adjustment module reduces the instrument backlight brightness, and the gateway sends the setting parameter of the external power supply to the interface power supply, so as to stop the interface power supply from supplying power to the external component, reduce power consumption, and save power consumption.
For another example, when the battery power is lower than 30%, the user may stop using the air conditioner or reduce the gear of the air conditioner, the vehicle-mounted display terminal sends the closing information or the gear reduction information of the air conditioner to the gateway, the gateway sends the closing information or the gear reduction information to the air conditioner controller, and the air conditioner controller controls the air conditioner to close or reduce the gear, so that energy consumption is reduced, and electricity consumption is saved.
And S3, the electric equipment control unit controls the corresponding electric equipment to switch to the power saving state according to the preset power saving state information.
Specifically, after receiving the power saving state information, the electrical device control unit controls the corresponding electrical device to switch to the power saving state, for example, at least one of the following is implemented: the navigation system searches the charging pile information near the vehicle or stops navigation; the screen backlight manager adjusts the screen backlight brightness of the vehicle-mounted display terminal to a preset brightness value; the task manager closes the entertainment functions except the navigation system or selectively closes the entertainment functions according to a preset; the interface power supply stops discharging outwards; the gear shifting controller controls the vehicle to be switched to an economic running mode; the instrument backlight adjusting module adjusts the backlight brightness of the vehicle instrument and the keys to a preset brightness value; the air conditioner controller controls an air conditioner of the vehicle to reduce an operation gear and start an internal circulation mode, or controls the air conditioner to be closed; the seat function controller reduces a seat comfort operation gear or closes a seat comfort mode; the window controller controls the windows and/or the skylight of the vehicle to be closed; the energy feedback controller adjusts the vehicle feedback to a preset gear; thus, the vehicle is caused to enter the power saving mode.
According to the method for managing the power consumption of the electric vehicle, the power saving state information can be conveniently set by a user based on the vehicle-mounted display terminal, the problem that the user does not know how to set the power saving information cannot occur, the power saving state information of each piece of electric equipment which is default or preset by the user is prestored in the vehicle-mounted display terminal, when a trigger instruction of the power saving mode is detected, the preset power saving state information is started by the vehicle-mounted display terminal to the electric equipment control unit, then the electric equipment control unit controls the corresponding electric equipment to be switched to the power saving state, the vehicle can rapidly enter the power saving mode, and the driving range of the vehicle is improved.
Further, in the power saving mode, the vehicle-mounted display terminal responds to a power saving state adjusting instruction of a user, generates power saving state adjusting information and sends the power saving state adjusting information to corresponding electric equipment; and the electric equipment adjusts the power saving state according to the power saving state adjusting information. In the power saving mode, the user can independently adjust the power saving state information through the vehicle-mounted display terminal, personalized setting is achieved, adjustment by the user is facilitated, and the vehicle cannot exit the power saving mode.
In some embodiments, based on the vehicle-mounted display terminal, the mode icon of the display interface can be edited and associated with the function, so that the trigger units of various driving modes can be set on the display interface of the vehicle-mounted display terminal. Wherein, the driving mode can comprise at least one of a comfortable energy-saving mode, an entertainment energy-saving mode, a driving energy-saving mode and a sport mode. The comfort can be preferentially ensured in the comfortable energy-saving mode, and the feedback gear of the vehicle is lower; the entertainment energy-saving mode can preferably ensure entertainment, the vehicle can be driven in the economic mode, and the multimedia can be in the optimal use state; the driving energy-saving mode can preferentially ensure the driving performance, the vehicle can drive in the motion mode, and the performance of accelerating for hundreds of kilometers is ensured, but other entertainment functions can be reduced or closed, for example, multimedia related to entertainment can be adjusted into the energy-saving mode. Or, the user can also customize the energy-saving mode, and set a corresponding trigger unit on the display interface of the vehicle-mounted display terminal. Or, personalized setting can be performed for each user, so that the driving habits of each user are guaranteed to be met, for example, when the user uses the vehicle, the user can be identified through the vehicle-mounted camera, and the matched energy-saving mode can be selected.
Specifically, in a low battery state, a user can be guided to trigger the vehicle to enter a power saving mode through the vehicle-mounted display terminal.
Or, in a non-low power state, the user can actively operate the power saving mode trigger unit displayed by the vehicle-mounted display terminal, so that the vehicle enters a power saving mode, and the user can also select other set or self-defined driving modes. For example, the vehicle-mounted display terminal receives a driving mode selection instruction of a user; the vehicle-mounted display terminal sends corresponding power saving state information to corresponding electric equipment according to the driving mode selection instruction, so that the vehicle enters a power saving state in the driving mode; or the vehicle-mounted display terminal is provided with a triggering unit of a user-defined power saving mode on a display interface, and when receiving a selection instruction of the user-defined power saving mode, the vehicle-mounted display terminal sends power saving state information of the user-defined power saving mode to the corresponding electric equipment to meet user-defined requirements of users.
