Description

Technical Field

[0001] The present invention relates to the field of automotive electronic technology, and in particular to a method and system for power state migration of an instrument and a central control system of a new energy vehicle. Background Art

[0002] At present, the most common method for the power status of the instrument and central control of traditional new energy vehicles is: according to the power mode of the whole vehicle, it is divided into 4 power modes: OFF / ACC / ON / START. In these 4 power modes, the instrument and central control correspond to different state migrations. In the OFF power mode, the instrument and central control are both in the off state; in the ACC power mode, the instrument is in the off state and the central control is in the working state; in the ON / START power mode, the instrument and central control are in full working state. With the development of the industry, new energy vehicles are not only a means of transportation, but also a living space for users. Compared with traditional new energy vehicles, the power mode of the living space has been increased. The instrument and central control are the interface for users to interact with the vehicle and the carrier of infotainment. It is necessary to redefine the state migration strategy of the instrument and central control in various power modes of the vehicle to meet the needs of various usage scenarios of the current vehicle and provide users with a car experience. Summary of the invention

[0003] In view of the above-mentioned defects of the prior art, the present invention proposes a method and system for power state migration of an instrument and a central control system of a new energy vehicle to solve the problems described in the background technology.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: a method for power state migration of a new energy vehicle instrument and a central control system, including a sleep mode, a wake-up mode, a standby mode, a driving mode, and a living space mode, wherein:

[0005] In sleep mode, the instrument panel and central control are divided into three working states: standby, pre-sleep, and sleep. When the vehicle power changes from wake-up mode or living space mode to sleep, the instrument panel and central control are in standby state, and the instrument panel screen displays the sleep interface; if there is an alarm signal, only the alarm indicator light is displayed, and the rest of the information is not displayed;

[0006] In wake-up mode, the instrument screen only displays some key information about the vehicle status according to the usage scenario; if there are other alarms, the relevant alarm prompt information will be displayed;

[0007] In standby mode, all ECUs of the vehicle are awakened and the vehicle network is fully active. At this time, the instrument screen and the central control screen are in a normal working display interface;

[0008] In driving mode, all vehicle power supply terminals are activated and the vehicle network is fully active, the powertrain system is ready, the vehicle is drivable, and the instrument screen and central control screen are in normal working display interface;

[0009] In living space mode, if an alarm signal is triggered, the corresponding alarm prompt information will be displayed. If there is no signal trigger, the screen will be in off state. The central control screen will enter the screen saver interface after 15 seconds of no operation from the normal working interface. If the user triggers the screen, the normal working interface will be displayed again.

[0010] Furthermore, in the sleep mode, the sleep interface is a black effect on the instrument display.

[0011] Furthermore, in the wake-up mode, the instrument screen displays some key information of the vehicle status including: remaining battery power, remaining hydrogen amount, and mileage.

[0012] Furthermore, in the living space mode, users can perform operations including but not limited to lighting, air conditioning, charging, and audio-visual entertainment.

[0013] Furthermore, in living space mode:

[0014] When the central control screen is playing a video, it will display normally; when it is in other function states, it will display the screen saver interface;

[0015] When a call is in progress and the Bluetooth connection is out of range, there will be no lighting conditions for 15 seconds and the central control screen will turn off and display the screen saver interface; when the connection is restored, the central control screen will display normally.

[0016] The present invention also proposes a computer system, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the power state migration method of the new energy vehicle instrument and central control system as described above is implemented.

[0017] The present invention has the following technical effects:

[0018] 1. Defines the power state migration strategy of the instrument and central control in the unique life scenarios of new energy vehicles, which can ensure that the instrument and central control are in the corresponding working state for the user's diverse application scenarios under various power modes of the vehicle, and minimize the energy consumption of the vehicle;

[0019] 2. Defines the display status of the instrument screen and central control screen under various power modes, so that users can clearly identify the current mode of the vehicle and avoid unnecessary operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0024] The present invention proposes a power state migration method for a new energy vehicle instrument and a central control system, including Sleep mode, Awake mode, Standby mode, Driving mode, and Living Space mode. Figure 1 The following is a diagram showing the state transition of the instrument and central control power supply:

[0025] (1) NM message (network management message) refers to the relevant message signal defined according to the vehicle network management;

[0026] (2) CAN sleep means that there are no relevant CAN messages on the vehicle bus;

[0027] (3) Alarm signals include: left and right turn signal, position light, charging connection, and door open signal;

[0028] (4) The screen turns on when: 1. Touching the central control screen; 2. There is an incoming / outgoing Bluetooth call or a call is in progress.

[0029] The migration strategies for the above modes are as follows:

[0030] In Sleep mode, the instrument panel and central control are divided into three working states: standby, pre-sleep, and sleep. When the vehicle power changes from Awake mode or Living Space mode to Sleep, the instrument panel and central control are in standby state. At this time, the instrument panel screen displays the Sleep interface. The Sleep interface is a black effect on the instrument panel. If there is an alarm signal, only the alarm indicator light is displayed, and the rest of the information is not displayed. Figure 2As shown, the central control screen is in the off state; if there is no alarm signal within 15s (time can be calibrated), the instrument screen will turn off and enter the pre-sleep state. In the pre-sleep state, the instrument screen and the central control screen are both off. At this time, according to the definition of vehicle network management, after CAN sleep for 120s (time can be calibrated), all functions of the instrument and central control are turned off and enter the sleep state (low power consumption mode). At this time, the instrument and central control no longer respond to external signals, achieving the purpose of saving power and avoiding rapid power consumption of the vehicle.

[0031] In Awake mode, depending on the usage scenario, the instrument screen only displays some key information about the vehicle status, including: remaining battery power, remaining hydrogen, and mileage; if there are other alarms, the relevant alarm prompt information will be displayed. Figure 3 As shown, it is convenient for users to grasp vehicle information before driving and plan travel plans reasonably.

[0032] In Standby mode, all ECUs of the vehicle are awakened and the vehicle network is fully active. At this time, the instrument screen and the central control screen are in normal working display interface;

[0033] In Driving mode, all vehicle power supply terminals are activated and the vehicle network is fully active, the powertrain system is ready, the vehicle is drivable, and the instrument screen and central control screen are in normal working display interface;

[0034] When the vehicle is used as a living place, it needs to enter the Living Space state. The systems that need to be activated in the vehicle life scene are interior lighting, air conditioning, charging, audio and video entertainment, etc. In this power mode, the instrument screen will display a special interface of the Living Space mode. If there is an alarm prompt signal, the corresponding alarm prompt information will be displayed. If there is no signal trigger, it will be in the screen off state; the central control screen will go from the normal working interface to the screen saver interface after 15 seconds of no operation. If the user triggers the screen, the normal working interface will be displayed again, which is convenient for users to perform lighting, air conditioning, charging, audio and video entertainment and other operations in the life mode. In Living Space mode:

[0035] 1. When the central control screen is playing a video, it will display normally; when it is in other function states, it will display the screen saver interface;

[0036] 2. During a call, if the Bluetooth connection is out of range, there will be no lighting conditions for 15 seconds, and the central control screen will turn off and display the screen saver interface; when the connection is restored, the central control screen will display normally.

[0037] The present invention achieves the following beneficial effects through the above method:

[0038] 1. Defines the power state migration strategy of the instrument and central control in the unique life scenarios of new energy vehicles, which can ensure that the instrument and central control are in the corresponding working state for the user's diverse application scenarios under various power modes of the vehicle, and minimize the energy consumption of the vehicle;

[0039] 2. Defines the display status of the instrument screen and central control screen under various power modes, so that users can clearly identify the current mode of the vehicle and avoid unnecessary operations.

[0040] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in the field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
