Description
Technical Field
The invention relates to the field of intelligent vehicle machine systems, in particular to a power management method and device of an intelligent vehicle machine system.
Background
With the development of economy, particularly the development of the automobile industry, the number of automobiles in the society is more and more at present, along with the improvement of the living standard of people, the automobiles are very popular as walking tools, the configuration requirements of consumers on the automobiles during purchasing the automobiles are higher and higher, and the intelligent automobile machines capable of realizing various functions are configured in the common automobile configuration in the market at present. Although the smart car machine can realize various functions, for example, an Advanced Driver Assistance System (ADAS) can be mounted to help reduce the driving pressure of the Driver. For example, entertainment services such as music and radio can be provided, or real-time interaction with a user can be performed through a graphical user interface, thereby helping the driver to add driving pleasure.
Among them, according to the definition of Wikipedia online encyclopedia, the current advanced driving assistance system generally includes a navigation and real-time traffic system TMC, an electronic police system ISA (Intelligent speed adaptation or interactive speed adaptation), a vehicle networking (Vehicular communication systems), an adaptive cruise control (adaptive cruise control), a Lane departure warning system ldws (Lane departure warning system), a Lane keeping system (Lane keep assist), a Collision avoidance or pre-Collision system (Collision avoidance or pre-Collision system), a Night Vision system (Night Vision system), adaptive light control (Adaptive light control), Pedestrian protection system (Pedestrian protection system), Automatic parking system (Automatic parking), Traffic sign recognition (Traffic sign recognition), Blind spot detection (Blind spot detection), Driver fatigue detection (Driver fatigue detection), downhill control system (Hill detector control), and Electric vehicle warning (Electric vehicle warning systems).
If a plurality of advanced driving assistance systems are mounted on one automobile and the plurality of advanced driving assistance systems are kept in an operating state, the battery of the automobile is seriously consumed. Also, during driving, the driver will typically choose to select entertainment services such as music and radio, rather than selecting to listen to both music and radio. Therefore, only a small part of service modules work, other service modules are in an idle state, but the idle service modules still consume the vehicle power supply and influence the electric quantity of the whole vehicle.
Particularly, as fossil fuels are increasingly tense, new energy automobiles are receiving attention from the world. The problem of consuming the vehicle power is particularly prominent on new energy automobiles. Once the electric quantity is excessively consumed, the number of the mileage which can be traveled by the new energy automobile is sharply reduced, which brings inconvenience to the driver.
Therefore, there is a need for a vehicle device system, a power management method and a power management device thereof, which can overcome the problem of power consumption of the idle service module without affecting the basic functions that can be realized by various service modules, so as to apply the vehicle power to the driving mileage as much as possible, rather than being wasted by the idle module.

Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
As described above, the present invention provides a power management method for a vehicle-mounted device system, please refer to fig. 1, where fig. 1 shows a flowchart of the power management method provided by the present invention.
As shown in fig. 1, the power management method provided by the present invention includes steps 100: classifying all the functional modules into a first-class functional module and a second-class functional module based on the use habits of users; and executing step 111 according to the state of the functional module: control a type of function module to enter an operational mode, and/or step 112: and controlling the second-class functional module to enter a sleep mode.
When the functional module is in the operational mode, it is in a high power state and when the functional module is in the sleep mode, it is in a low power state. In the above working mode, even if each functional module does not actually work, the chip still keeps a normal working state and has larger power. In the sleep mode, the sleep current is set to the minimum current required to be maintained by each module chip, which is about mA level, and the power is low. Therefore, one type of function module can be regarded as a busy module, and the second type of function module can be regarded as an idle module.
Specifically, the power management method provided by the invention is configured in the vehicle machine system. Generally, a car machine system includes a plurality of function modules to accomplish a function of increasing intelligence, thereby improving user experience. The plurality of functional modules include but are not limited to FM radio module, song play module, GPS orientation module, WIFI online module, 4G online module, bluetooth module, NFC module, module of backing a car, voice module, speech recognition module, vehicle event data recorder module, USB module, the module of charging of USB, screen brightness module etc..
In step 100, the usage habits of the user may include, but are not limited to, the user being used to drive for a fixed period of time, and being used to listen to the broadcast while driving for the fixed period of time, and being used to listen to the song while driving for another fixed period of time. Alternatively, the user is accustomed to starting at a fixed place and is accustomed to not navigating or the like when starting from the fixed place.
For example, the user is 7: 00-9: driving to work between 00, in the morning 7: 00-9: in the time period 00, the broadcast program of a certain station is very attractive to the user, and therefore, the user is in the morning of 7: 00-9: and is used to listening to the broadcast during the time period of 00. Under the condition, the FM radio module can be classified into a busy module according to the habit of a user, and the song playing module and the internet surfing module, the Bluetooth module and the like which are associated with the song playing module can be classified into idle modules. To off hours, such as 17 pm: 00-19: 00, during which the user is not accustomed to listening to the broadcast, but to listening to the song in the handset. Under the condition, the FM radio module can be classified as an idle module according to the habit of the user, and the song playing module and the internet access module associated with the song playing module or the Bluetooth module communicating with the mobile phone can be classified as a busy module.
For another example, when a user departs from home in the morning of a workday, usually to a company for work, while commuting the line user is already familiar with, it may be considered that the user does not need the navigation function, in which case the navigation module and the GPS positioning module associated with the navigation module, etc. may be classified as idle modules. The same applies to the case where the user departs from the company at night on a weekday, usually goes home from work, and since the user is familiar with the commuting route, the user can also be considered to not need the navigation function, and the navigation module and the GPS positioning module associated with the navigation module can be classified as idle modules. Conversely, if the user is found to be suddenly present in an unfamiliar location, even in the city of the province, the user may be considered unfamiliar with the road and may need to use the navigation function, which may be classified as a busy module along with a GPS positioning module associated with the navigation module, etc.
Subsequently, in step 111 and/or step 112, the first type of function module is controlled to enter the working mode, and the second type of function module is controlled to enter the sleep mode, respectively. Specifically, because the power management system provided by the invention is constructed on the vehicle machine system, when the vehicle machine system is started up initially, all the function modules can be defaulted to enter the working mode, therefore, when the functions are classified into idle modules or busy modules, the idle modules can be controlled to enter the dormant mode, and the busy modules are kept in the working mode. Further, the second type function module can be made to sleep by means of commands or I/O by means of upper layer software. In this state, the sleep current required by the second class of functional blocks only needs to meet the minimum current maintained by the chip, which is about mA. Therefore, the idle module is controlled to be dormant, and a large amount of driving electricity can be saved.
According to the power supply management method provided by the invention, the function of saving the driving electric quantity can be achieved according to the use habit of the user, good interactive experience can be provided for the user, and in the above example, the trouble of switching the song playing module and the FM radio module in the work and work pictures can be saved for the user, so that the power supply management method is more intelligent and humanized.
Referring further to fig. 2, fig. 2 is a flowchart illustrating a power management method according to an embodiment of the invention.
Preferably, in the embodiment shown in fig. 2, after the vehicle-mounted device system is started, the power management method further includes a step of determining whether the user selects to enter the power saving mode, and continuing to perform subsequent classification steps in response to an instruction that the user needs to start the power saving mode.
Referring to fig. 2, as shown in fig. 2, after the car-on-board system is started, it is first determined whether the user selects to enter the power saving mode. If the user does not need to start the power saving mode, all the functional modules are started to enter the working mode, which may cause the situation that the idle modules waste electric energy. If the user needs to start the power saving mode, the power management method intelligently classifies all the functional modules according to the use habits of the user, so that the idle modules are dormant in a targeted manner, and the electric quantity is saved.
In the above embodiment, the power management method provided by the invention gives the user the right to determine whether the power saving mode needs to be started, so that the user has more control over the use of the vehicle-mounted device system, and the user experience is further enhanced.
In an aspect of the foregoing embodiment, preferably, the power management method further includes: and collecting behavior data of all functional modules used by the user, and inducing the use habits of the user according to the behavior data.
Specifically, in an embodiment, the usage habit of the user can be attributed to the time that the user uses the function module through the background management service of the system, such as: when the user uses the car machine system, the background management service records the corresponding usage record, for example, 12: 00-13: in the driving process of the 00 time period, the user has the behaviors of surfing the internet by using a certain APP and the like. The behavior data are stored in a database as behavior big data of the user, and the system refines the same factors through a fuzzy algorithm when in idle and busy hours, thereby deducing the use habit of the user as the condition and basis for controlling the power management method. As mentioned above, if the same factors are extracted according to the fuzzy algorithm, the user is found to be on duty every day in the period of time 7: 00-8: 00 this hour, the song playing module is used to listen to songs, but the FM radio module is not used. The usage habits of the user may be correspondingly "at 7: 00-8: 00 hours, a song playing module is used for listening songs, therefore, the song playing module of the car machine system, the related sound module, the internet surfing module and the like need to be ensured to be in a working mode, and the FM radio module can be converted into a sleep mode.
Specifically, in another embodiment, the usage habit of the user can be attributed to the location of the functional module used by the user through the background management service of the system, such as: when the user uses the car machine system, the background management service records the corresponding usage record, for example, the user does not use the navigation function and other behaviors each time the user starts from a company. The behavior data are stored in a database as behavior big data of the user, and the system refines the same factors through a fuzzy algorithm when in idle and busy hours, thereby deducing the use habit of the user as the condition and basis for controlling the power management method. As described above, if the same factor is extracted according to the fuzzy algorithm, it is found that the user is only required to start from the specific location of the company, and is not used to use the navigation function. The usage habit of the user can be correspondingly 'navigation is not used from the company', so that the navigation module of the car machine system and the corresponding GPS positioning module can be switched to the sleep mode.
Preferably, the power management method provided by the invention can comprehensively conclude the use habits of the users according to the time and the place of the users using the function modules when collecting the behavior data of all the function modules used by the users and concluding the use habits of the users according to the behavior data, thereby more accurately providing intelligent and humanized services for the users.
In another aspect of the above embodiment, it is preferable that the functional module temporarily changes a predetermined habit after entering the sleep mode due to the user's autonomy, and thus the functional module can resume the operation mode in response to the wake-up command in the sleep mode.
The scheme mainly considers that the non-working module enters the sleep mode, and is actually a standby mode with low power consumption, and when the user continues to use the standby module, the sleeping module can be immediately awakened. There are various ways of waking up (i.e. the form of a wake-up command), including voice wake-up and interface click wake-up. For example, the FM radio module is in a sleep state, and when a user needs to search for a channel to listen to a broadcast, the user can go to the interactive interface of the FM radio module for operation.
In addition, in another embodiment, for a functional module currently in a sleep state, the sleep state is correspondingly prompted on an interactive interface of the module to prompt a user about the state of the module, and the user can wake up the module at any time when needing to use the module again.
According to the power supply management method provided by the invention, the idle functional module can be made to sleep in a targeted manner intelligently according to the use habit of the user, so that the utilization rate of the vehicle-mounted system is effectively improved, the power saving effect is realized under the condition that the normal use of the user is not influenced, and the power supply management method is particularly suitable for being configured and used on vehicles which are sensitive to electric quantity consumption, such as new energy vehicles and the like. The power management method provided by the invention intelligently controls the functional module to work or sleep according to the use habit of the user, and provides the awakening function when the user changes the daily behavior of the user, so that the dormant module works again, therefore, the power management method provided by the invention is more humanized, and the user experience is better.
