[0056] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. The embodiments described with reference to the drawings are exemplary and are intended to be used to explain this application, and should not be understood as limiting this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] FIG1 is a flow chart of a battery management method according to an exemplary embodiment of the present application. As shown in FIG1 , the battery management method includes the following steps:

[0058] S101, obtaining the current power status of the integrated vehicle computer.

[0059] The power management method of the present application is applied to an integrated vehicle computer including a TBOX to perform power management on the integrated vehicle computer. As shown in FIG2 , the integrated vehicle computer integrates the TBOX and the traditional vehicle computer, and the TBOX and the vehicle computer share an operating system, an MCU, and a SOC, etc.

[0060] In some embodiments, an identifier corresponding to the current power state may be obtained through a serial port to determine the current power state of the integrated vehicle computer.

[0061] S102: Detect a preset trigger signal, and determine a target power state according to the preset trigger signal, wherein the preset trigger signal is used to trigger switching of the current power state.

[0062] The integrated vehicle computer in the embodiment of the present application includes multiple power states, and the switching between any two power states corresponds to one or more pre-set trigger signals, namely the preset trigger signals. In the embodiment of the present application, whether the preset trigger signals are received is detected in real time, for example, by detecting the level of the corresponding pin to determine whether the preset trigger signals are present.

[0063] The preset trigger signal is used to trigger the current power state to switch, and the current power state can switch to one or more other power states. Therefore, it is necessary to determine the target power state based on the detected preset trigger signal, that is, to determine which other power state the preset trigger signal can trigger the current power state to switch to.

[0064] S103 : Adjusting the working state of each module in the integrated vehicle computer according to the current power state and the target power state, so as to switch the current power state of the integrated vehicle computer to the target power state.

[0065] After determining the current power state and the target power state to be switched to, the operating state of each module in the integrated vehicle computer is adjusted to achieve the power state transition. Since modules consume different power in different operating states, the operating state of each module can also be understood as the module's power consumption state.

[0066] In summary, the power management method proposed in this application is applied to an integrated vehicle computer including a TBOX, to obtain the current power state of the integrated vehicle computer, and to detect whether a preset trigger signal is received. These preset trigger signals are used to trigger the switching of the current power state. According to the received preset trigger signal, the target power state to be switched to is determined. According to the current power state and the target power state, the working state of each module in the integrated vehicle computer is adjusted, and then the power consumption of the hardware of each module is adjusted. This application designs different power states to maintain the normal operation of the vehicle computer and TBOX under different working conditions. Under different power states, each module of the integrated vehicle computer is in a different working state, and the power consumption is also different. By responding to the preset trigger signal to switch between power states, while ensuring that the integrated vehicle computer provides the necessary functional support for the entire vehicle, the power consumption of the integrated vehicle computer under different working conditions is saved, thereby reducing the power consumption of the entire machine.

[0067] Based on the above embodiment, as shown in FIG3 , the above step S102 of “determining the target power state according to the preset trigger signal” includes the following steps:

[0068] S301 , determining, according to the preset trigger signal, a target state switching condition satisfied by the preset trigger signal from state switching conditions corresponding to the current power state.

[0069] The current power state can switch to multiple other power states. For any two power states, corresponding state transition conditions can be set for both forward and reverse switching. Each state transition condition can include one or more sub-conditions. These sub-conditions can be combined using AND, OR, or other relationships to form a state transition condition. By determining whether these sub-conditions are met, the overall state transition condition can be further confirmed.

[0070] In some embodiments, each sub-condition may correspond to a preset trigger signal. As a feasible implementation method, when a preset trigger signal corresponding to a sub-condition is received or detected, the sub-condition may be considered to be met; when a preset trigger signal corresponding to a sub-condition is not received or detected, the sub-condition may be considered to be not met.

[0071] In this way, according to the detected preset trigger signal, a state switching signal that is satisfied is screened out from a plurality of state switching conditions corresponding to the current power state as the target state switching condition.

[0072] S302: Set another power state other than the current power state corresponding to the target state switching condition as the target power state.

[0073] Each state switching condition corresponds to two power states. For example, for power state 1, the state switching conditions corresponding to power state 1 include the state switching conditions for switching from other power states to power state 1, and the state switching conditions for switching from power state 1 to other power states.

[0074] The current power state of the integrated vehicle computer is the power state it is currently in and the starting state for power state switching. Therefore, the target state switching condition is the state switching condition for switching from the current power state to another power state. Therefore, after determining the target switching condition, the target power state to be switched to can be further determined. This is the other power state other than the current power state of the two power states corresponding to the target state switching condition.

[0075] The embodiment of the present application determines the target switching condition that is satisfied from multiple state switching conditions corresponding to the current power state based on the detected preset trigger signal, thereby determining which new power state the current power state is to be switched to, thereby being able to respond to different preset trigger signals to achieve switching between different power states.

[0076] Based on the above embodiment, the power state includes a full-function state, a semi-function state, a local mode state, a pre-sleep mode state and a sleep mode state; wherein the pre-sleep mode state can immediately be a state ready to enter fast-start sleep mode.

[0077] The levels of the full-function state, the semi-function state, the local mode state, the pre-sleep mode state, and the sleep mode state are in descending order. It can also be understood that the power consumption of the integrated vehicle computer in the full-function state ≥ the power consumption in the semi-function state ≥ the power consumption in the local mode state ≥ the power consumption in the pre-sleep mode state ≥ the power consumption in the sleep mode state. At the same time, the functions that the integrated vehicle computer can achieve in the full-function state ≥ the functions that can be achieved in the semi-function state ≥ the functions that can be achieved in the local mode state ≥ the functions that can be achieved in the pre-sleep mode state ≥ the functions that can be achieved in the sleep mode state.

[0078] In some embodiments, state switching conditions may be set between different power states to implement switching between any two power states. FIG4 is a schematic diagram of a power state switching topology.

[0079] In some embodiments, switching from a high-level power state to a low-level power state can be done step by step to buffer and shut down various functions on the integrated vehicle computer; when switching from a low-level power state to a high-level power state, it can be switched across levels to respond to user needs in a timely manner.

[0080] The state switching conditions include a step-by-step natural switching condition from a high-level power state to a low-level power state, and a triggered switching condition from a low-level power state to a high-level power state;

[0081] The natural switching condition from the full-function state to the semi-function state is that the vehicle is turned off and the ACC is powered off;

[0082] In addition to the step-by-step natural switching condition from the full-function state to the semi-function state, other step-by-step natural switching conditions may be established by a preset time interval during which no operation request is received;

[0083] The trigger switching condition when switching from a low-level power state to a high-level power state can be set by a preset trigger source.

[0084] In some embodiments, the trigger source may include but is not limited to whether the battery power supply is turned on (such as B+ is turned off or on), whether the ACC power supply is turned on (such as ACC is turned off or on), whether the ignition switch is turned on (such as IG is turned off or on), and whether the vehicle is awakened, etc.

[0085] Each trigger source generates a corresponding preset trigger signal. For example, when B+ is connected and the battery power supply is turned on, the corresponding preset trigger signal is transmitted to the power management device to inform the battery management device that the vehicle turns on the battery power supply.

[0086] In some embodiments, the step-by-step natural switching conditions may include the following:

[0087] Table 1 Example of step-by-step natural switching conditions corresponding to switching from a high-level power state to a low-level power state

[0088] In some embodiments, the triggering switching conditions may include the following conditions as shown in Table 2:

[0089] Table 2 Example of trigger switching conditions corresponding to switching from a low-level power state to a high-level power state

[0090] Based on the above embodiment, as shown in FIG5 , in step S103 , “adjusting the working state of each module in the integrated vehicle computer according to the current power state and the target power state” includes:

[0091] S501 : Determine, from among the modules of the integrated vehicle computer, a target module whose operating state in the current power state is different from that in the target power state.

[0092] Each module of the integrated vehicle computer has different working states under different power supply states. It can also be understood that each module has different power consumption under different power supply states.

[0093] The working status of the module under different power states can be pre-set as needed, and this application does not impose any restrictions.

[0094] S502 : Switch the working state of the target module from the working state corresponding to the current power state to the working state corresponding to the target power state.

[0095] The module whose operating state is different between the current power state and the target power state is selected as the target module for operating state adjustment. Specifically, the target module's operating state is switched from operating state 1 under the current power state to operating state 2 under the target power state. This adjusts the target module's power consumption from operating state 1 to operating state 2.

[0096] This completes the switch from the current power state to the target power state, thereby reducing the power consumption of the entire system while meeting the operating requirements of each component in the integrated vehicle computer.

[0097] In some embodiments, the modules of the integrated car computer may include but are not limited to functional modules corresponding to the car computer, such as screens, speakers and other components; functional modules corresponding to TBOX, such as CAN, antennas, Bluetooth, GPS, Ethernet and other components; shared modules are modules shared by traditional car computers and TBOX, such as system-on-chip SOC, microcontroller unit MCU and memory components DDR, etc.

[0098] The working status of each module can be divided into normal working status (i.e. the component is powered normally) and operation stop status, wherein the operation stop status can be a dormant state (i.e. the component is disconnected from the external connection and is on standby) or a power-off state (i.e. the component is turned off and no longer provides functional services).

[0099] In some embodiments, the power state can be divided according to the working state of each module in the integrated vehicle computer, that is, the working state of each module is different under different power states. Table 3 is an example table of the correspondence between power state and working state of each module.

[0100] Table 3 is an example table of the correspondence between power status and the working status of each module

[0101] In summary, the power management method proposed in this application is applied to an integrated vehicle computer including a TBOX, to obtain the current power state of the integrated vehicle computer, and to detect whether a preset trigger signal is received. These preset trigger signals are used to trigger the switching of the current power state. According to the received preset trigger signal, the target power state to be switched to is determined. According to the current power state and the target power state, the working state of each module in the integrated vehicle computer is adjusted, and then the power consumption of the hardware of each module is adjusted. In this application, the modules of the integrated vehicle computer are in different working states under different power states, and the power consumption is also different. By responding to the preset trigger signal to switch between power states, while ensuring that the integrated vehicle computer provides the necessary functional support for the entire vehicle, the power consumption of the integrated vehicle computer under different working conditions is saved, thereby reducing the power consumption of the entire machine.

[0102] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0106] The state switching module 603 is configured to adjust the working state of each module in the integrated vehicle computer according to the current power state and the target power state, so as to switch the current power state of the integrated vehicle computer to the target power state.

[0107] In the embodiment of the present application, the determining module is further configured to:

[0108] According to the preset trigger signal, a target state switching condition satisfied by the preset trigger signal is determined from the state switching conditions corresponding to the current power state.

[0109] Another power state other than the current power state corresponding to the target state switching condition is used as the target power state.

[0110] In an embodiment of the present application, the power state includes a full-function state, a semi-function state, a local mode state, a pre-sleep mode state, and a sleep mode state.

[0111] The levels of the full-function state, the semi-function state, the local mode state, the pre-sleep mode state, and the sleep mode state are sequentially decreased.

[0112] The state switching conditions include a step-by-step natural switching condition from a high-level power state to a low-level power state, and a triggered switching condition from a low-level power state to a high-level power state.

[0113] The natural switching condition from the full-function state to the semi-function state is that the vehicle is turned off and the ACC is powered off.

[0114] In addition to the step-by-step natural switching condition from the full-function state to the semi-function state, other step-by-step natural switching conditions are established by a preset time interval in which no operation request is received.

[0115] In an embodiment of the present application, the trigger switching condition is formulated by a preset trigger source, and the trigger source includes whether the battery power supply is turned on, whether the ACC power supply is turned on, whether the ignition switch is turned on, and whether the vehicle is awakened.

[0116] In the embodiment of the present application, the state switching module is further configured to:

[0117] From the modules of the integrated vehicle computer, a target module whose working state in the current power state is different from the working state in the target power state is determined.

[0118] The working state of the target module is switched from the working state corresponding to the current power state to the working state corresponding to the target power state.

[0120] The working state of the module includes a normal working state and a stop state, and the stop state is a dormant state or a power-off state.

[0121] The device is further configured to divide the power supply state according to the working state of the module.

[0122] In summary, the power management device proposed in this application is applied to an integrated vehicle computer including a TBOX, to obtain the current power state of the integrated vehicle computer, and to detect whether a preset trigger signal is received. These preset trigger signals are used to trigger the switching of the current power state. According to the received preset trigger signal, the target power state to be switched to is determined. According to the current power state and the target power state, the working state of each module in the integrated vehicle computer is adjusted, and then the power consumption of the hardware of each module is adjusted. This application designs different power states to maintain the normal operation of the vehicle computer and TBOX under different working conditions. Under different power states, each module of the integrated vehicle computer is in a different working state, and the power consumption is also different. By responding to the preset trigger signal to switch between power states, while ensuring that the integrated vehicle computer provides the necessary functional support for the entire vehicle, the power consumption of the integrated vehicle computer under different working conditions is saved, thereby reducing the power consumption of the entire machine.

This application designs different power states to maintain the normal operation of the vehicle computer and TBOX under different working conditions. Under different power states, each module of the integrated vehicle computer is in a different working state and has different power consumption. By responding to the preset trigger signal to switch between power states, while ensuring that the integrated vehicle computer provides the necessary functional support for the entire vehicle, the power consumption of the integrated vehicle computer under different working conditions is saved, thereby reducing the power consumption of the entire machine.
