As shown in fig. 1, an embodiment of the present invention provides a power management method for a cabin domain controller, including:
and step S100, acquiring a control instruction and the current power mode of the domain controller.
Specifically, the control command includes control actions of the driver or the passenger on the vehicle, such as a key having a specific function in the vehicle, a state of the vehicle (such as driving, parking, flameout, etc.), interactive actions of opening and closing a door, alarming the vehicle, locking and unlocking the vehicle, and the like. The control command also comprises specific trigger conditions, such as conditions that the command is not received within time, the system is abnormal, the system is closed, the electric quantity reaches a specific value, the temperature reaches a specific value and the like.
The domain controller has multiple power supply modes, different power supply modes are determined according to different conditions in various states of the vehicle, and the different power supply modes have corresponding operation modes, so that the most appropriate operation mode is determined according to the vehicle state or user requirements. For example, in one embodiment, when the vehicle is in a normal running state, a user enables the vehicle to enter a sleep state through a start key, and at the time, the central control screen of the vehicle, the air conditioner and the light in the vehicle are turned off, so that the power consumption of the vehicle is reduced; in another embodiment, when the low-voltage battery of the vehicle is low, a trigger condition is met, the vehicle automatically enters a dormant state, and when the low-voltage battery of the vehicle is recovered, another trigger condition is met, and the vehicle is recovered from the dormant state to a starting state.
In one embodiment, the intelligent cockpit domain controller has the functions of a vehicle-mounted infotainment system, and comprises a central control screen or a touch screen with the functions of navigation, music playing and the like; the functions of DMS (driver behavior detection), OMS (passenger behavior detection and the like) can be selected and fused; in the aspect of driving assistance, the driving assistance system can be combined with an ARHUD (augmented reality head-up display) and an AVM (panoramic monitoring video system), and equipment is controlled through a domain controller according to the requirements of a user or after a trigger condition is identified.
In another embodiment, the operational mode of the domain controller for a future period of time is determined by the control instructions and the domain controller being in common. For example, when the automobile is currently in a power-on state, the switch is detected to be clicked, and the central control screen is controlled by the domain controller to be lightened; when the automobile is in a bright screen state and is not electrified, the switch is detected to be clicked, and the whole automobile is controlled to be electrified through the domain controller.
And step S200, judging whether the control instruction meets a mode switching condition according to the current power mode.
Specifically, the power mode may be classified according to a usage scenario of the domain controller, for example, the power mode may be classified into a normal operation mode, a non-operation mode, and an abnormal operation mode. The normal working mode comprises a mode when the automobile runs or is ready to run; the non-working mode comprises a mode of a vehicle just starting or a vehicle dormant state; the abnormal operation mode comprises the mode of the automobile when the software and the hardware are abnormal.
In one embodiment, whether the mode needs to be switched is judged according to the power mode and the control instruction of the domain controller, for example, when the automobile runs normally and the domain controller is in the working mode, the automobile door is opened, and at the moment, the domain controller judges that the situation does not belong to the situation that passengers get off the automobile, so the working mode is not switched; when the automobile is in a parking state and the domain controller is in a working mode, the condition of driving the automobile door occurs, and the domain controller judges that the automobile is in a normal getting-off condition at the moment, so that the mode is switched to a non-working mode.
In another embodiment, the domain controller has higher power consumption when in the normal operation mode, and operates in the down-conversion mode when in the non-operation mode or the abnormal operation mode, and the power consumption is lower.
Step S300, if the mode switching condition is met, determining a target power supply mode according to the control instruction, and switching the domain controller from the current power supply mode to the target power supply mode.
Specifically, after the mode switching condition is satisfied, the power mode to be switched is determined according to a specific control instruction. In one embodiment, after the mode switching condition is met, the type and specific parameters of the control command are determined, and the power mode to be switched is determined according to the type and the specific parameters. The types comprise active instructions and passive instructions, wherein the active instructions comprise instructions actively triggered by a driver or a passenger, such as pressing a start key, opening a vehicle door, locking the vehicle and the like; the passive instruction comprises an overtime non-acceptance instruction, residual capacity, environment temperature outside the automobile and other instructions. The specific parameters comprise temperature values, timeout time values, remaining percentage of electric quantity and other parameters.
And step S400, controlling the vehicle to enter a target state according to the control command.
Specifically, after the control domain controller enters the target power mode, the control domain controller enters the target state according to the control instruction and the preset switching scheme. Since the states in different power modes are different and each power mode has multiple states, after switching to a new power mode, the target state of the domain controller needs to be further confirmed to match the current functional requirements.
In one embodiment, after the domain controller is switched from the normal operating mode to the non-operating mode, the domain controller analyzes the control command, and the control command is a power remaining percentage command in the passive command, so that the domain controller enters a dormant state in the non-operating mode after detecting that the low-voltage battery is low in power, and the mode and the state are switched.
Compared with the prior art, the domain controller is divided into a plurality of operation modes by fully knowing the requirements of users, and each operation mode is provided with a plurality of states. When the control instruction is detected, determining whether the working mode of the domain controller needs to be switched or not by taking the mode or state of the domain controller as a judgment basis and combining the control instruction, and ensuring that different working modes are determined according to different conditions, on one hand, the processing efficiency can be improved by the specific working mode; on the other hand, the power consumption of the domain controller can be effectively reduced by determining the working mode according to the requirement. After the working mode of the domain controller is switched, the target state of the domain controller is further determined through the control instruction, and various devices carried by the adaptive vehicle are guaranteed to meet the diversity requirements of users through the combined action of the domain controller, the control instruction and the mode in which the domain controller is located.
Optionally, as shown in fig. 2, after the determining whether the control instruction satisfies the mode switching condition according to the current power mode, the method further includes:
step S210, if the mode switching condition is not met, judging whether the state switching condition is met according to the control instruction;
and step S220, if the state switching condition is met, controlling the vehicle to enter the target state according to the control instruction.
In an embodiment, after combining the power mode in which the domain controller is located with the received control instruction, the domain controller determines that the mode switching condition is not satisfied, that is, the power mode in which the domain controller is located is not switched, and further determines whether the operating state needs to be switched in the power mode on the basis of the determination, so that it determines whether the state switching condition is satisfied according to the control instruction.
When the state switching condition is met, entering a target state according to the control instruction; and when the switching condition is not met, the working state is not changed if the switching condition is not met and the change is not needed.
Optionally, as shown in fig. 3, the determining whether the control instruction satisfies a mode switching condition according to the current power mode includes:
step S201, judging whether the domain controller is in a preset state;
step S202, if the control command is in the preset state, judging whether the control command is a switching command;
step S203, if yes, it indicates that the mode switching condition is satisfied.
Specifically, in different working modes of the domain controller, a plurality of working states are provided, but only in partial states, the state with the requirement of switching the working modes is determined as a preset state by setting the preset state, and the preset state is used as one of mode switching conditions to ensure that the working modes are switched according to the requirement of a user; for the state without the switching requirement, the preliminary filtering may be performed in step S201, so as to reduce the calculation amount of the domain controller on the basis of meeting the requirement of the user.
After the preliminary screening in step S201, it is further determined whether the acquired control instruction is a switching instruction. Specifically, since the control commands have different types and different values, in one embodiment, the user operation and the vehicle state command having the mode switching requirement are classified as the switching command, so that the user requirement is ensured to be met, and the working mode is ensured to be switched at the first time when the user or the vehicle sends the command. Firstly, judging whether the type of the control instruction is a corresponding switching instruction, if so, judging whether the numerical value of the control instruction meets a preset threshold value, if so, indicating that the control instruction is a switching instruction meeting the requirement, executing step S203, meeting the mode switching condition, and switching the modes.

Specifically, the audio/video content playing state includes a playing startup animation state; the first display state includes a state in which the display portion displays content; the second display state includes a state in which the entire display content is displayed. For example, in one embodiment, the first display state includes a display state of a center control screen after the vehicle is awakened, and only displays part of necessary display contents, including a rotating speed, a residual capacity and the like; the second display state includes the entire display content, such as speed, navigation, or other display content contained by the virtual cockpit.
