[0048] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0049] With the upgrading and iteration of the automobile industry, the car system has developed from the original audio and video player and mechanical instrument panel to the user's third living space, integrating multiple functions such as entertainment, office, life, and social interaction. The product form has also developed from a separate single controller to a highly integrated, high-performance intelligent domain controller.

[0050] The vehicle computer system at least includes a system on chip (System on Chip, SOC), a screen and peripheral devices. The SOC is responsible for processing various computing tasks in the vehicle computer system, including control, communication, data processing, etc. The screen mentioned in this embodiment refers to a display screen, not a touch screen. In other words, the screen can display driving data, including but not limited to average fuel consumption, instantaneous fuel consumption, outdoor temperature, average vehicle speed, driving time, charging information, etc.; the screen can also realize navigation and entertainment functions, such as providing navigation services, displaying navigation routes, and providing music, video and other entertainment forms. Peripheral devices may include speakers, microphones, Wireless Fidelity (Wireless Fidelity, WiFi), Bluetooth, etc.

[0051] like Figure 1 As shown, it shows a method flow chart of a method for power on and off management of a vehicle system provided by an embodiment of the present application, and the method for power on and off management of a vehicle system can be applied to electric vehicles. The method for power on and off management of a vehicle system can include:

[0052] Step 101, when receiving a power-off signal of the electric vehicle, detecting whether the electric vehicle is in a charging state.

[0053] The power-off signal may be a KL15 signal.

[0054] After parking, the user may need to charge the electric vehicle. When charging the electric vehicle, it is usually necessary to display the charging information on the screen of the vehicle system so that the user can understand the charging process. The charging information may include but is not limited to: the charging status indicator light showing green, the charging current, the charging power, and the battery power.

[0055] If the electric vehicle is in a charging state, the vehicle system needs to light up the screen and display charging information on the screen, that is, execute step 102; if the electric vehicle is not in a charging state, the vehicle system does not need to light up the screen, that is, execute step 103.

[0056] Step 102, if the electric vehicle is in a charging state, the vehicle system is controlled to enter a first state, where the first state means keeping the SOC working normally, lighting up the screen to display charging information, and cutting off the power supply of peripheral devices.

[0057] In the first state, the SOC can work normally, the screen displays charging information, and the peripheral devices are powered off. Since the peripheral devices and the touch screen are powered off, the screen can only display information but cannot be operated.

[0058] If the user needs to use the car again after temporarily parking and powering off, the SOC can be used directly, saving the time of waiting for the SOC to restart.

[0059] Step 103, if the electric vehicle is not in a charging state, the vehicle system is controlled to enter a second state, where the second state means keeping the SOC working normally, turning off the screen backlight, and cutting off the power supply of peripheral devices.

[0060] In the second state, the SOC can operate normally, the screen backlight is turned off, and peripheral devices are powered off.

[0061] If the user needs to use the car again after temporarily parking and powering off, the SOC can be used directly, saving the time of waiting for the SOC to restart.

[0062] Step 104, start timing when the vehicle computer system is in the second state, and obtain the state information of the electric vehicle in real time during the timing process.

[0063] If the user parks the car for a long time, the static power consumption of keeping the SOC working normally for a long time will be large, so the car system needs to cut off the power supply of the SOC.

[0064] In order to determine whether the user is parking temporarily or for a long time, the vehicle system needs to obtain the status information of the tram in real time within a period of time and make a judgment based on the status information. The status information can be set according to actual needs and is not limited here.

[0065] Step 105, determining whether to control the vehicle system to enter a network sleep state according to the state information, where the network sleep state means cutting off the power of the SOC and the screen.

[0066] When the timing has not ended, the vehicle system judges the status information obtained each time. If the judgment result is to continue to maintain the second state, the timing continues; if the judgment result is to control the vehicle system to enter other states, the timing ends.

[0067] If the vehicle system is still in the second state when the timing ends, it is determined that the user is parking for a long time. At this time, the vehicle system is controlled to enter the network sleep state, that is, the power supply of the SOC and the screen is cut off.

[0068] To summarize, the power-on and power-off management method of the vehicle system provided in the embodiment of the present application, when receiving the power-off signal, if the electric vehicle is in a charging state, the SOC is kept working normally, the screen is lit to display the charging information, and the power supply of the peripheral devices is cut off; if the electric vehicle is not in a charging state, the SOC is kept working normally, the backlight of the screen is turned off, and the power supply of the peripheral devices is cut off. In these two states, the SOC in the vehicle system works normally. If the user temporarily stops the car and powers off the car and uses it again, the time waiting for the SOC to restart can be saved.

[0069] The timing starts when the vehicle system is in the second state, and the status information of the tram is obtained in real time during the timing process; according to the status information, it is determined whether to control the vehicle system to enter the network sleep state. The network sleep state means cutting off the power supply of the SOC and the screen. In this way, after the user parks the vehicle for a period of time, the static power consumption of the tram when it is not used for a long time can be reduced to avoid unnecessary energy loss.

[0070] The vehicle computer system can smoothly switch between the first state, the second state and the network sleep state, realizing multi-level power state management of the vehicle computer system.

[0071] like Figure 2 As shown, it shows a flow chart of a method for managing power on and off of a vehicle system provided by an embodiment of the present application, and the method for managing power on and off of a vehicle system can be applied to electric vehicles. The method for managing power on and off of a vehicle system can include:

[0072] Step 201, when receiving a power-off signal of the electric vehicle, detecting whether the electric vehicle is in a charging state.

[0073] The power-off signal may be a KL15 signal.

[0074] After parking, the user may need to charge the electric vehicle. When charging the electric vehicle, it is usually necessary to display the charging information on the screen of the vehicle system so that the user can understand the charging process. The charging information may include but is not limited to: the charging status indicator light showing green, the charging current, the charging power, and the battery power.

[0075] Specifically, the vehicle system can determine that the electric vehicle is in a charging state when it receives a charging indicator light signal and the BMS_ChgSts parameter is not 0x1, otherwise, it determines that the electric vehicle is not in a charging state.

[0076] If the electric vehicle is in a charging state, the vehicle system needs to light up the screen and display charging information on the screen, that is, execute step 202; if the electric vehicle is not in a charging state, the vehicle system does not need to light up the screen, that is, execute step 203.

[0077] Step 202, if the electric vehicle is in a charging state, the vehicle system is controlled to enter a first state, where the first state means keeping the SOC working normally, lighting up the screen to display charging information, and cutting off the power supply of peripheral devices.

[0078] In the first state, the SOC can work normally, the screen displays charging information, and the peripheral devices are powered off. Since the peripheral devices and the touch screen are powered off, the screen can only display information but cannot be operated.

[0079] If the user needs to use the car again after temporarily parking and powering off, the SOC can be used directly, saving the time of waiting for the SOC to restart.

[0080] Step 203, if the electric vehicle is not in a charging state, the vehicle system is controlled to enter a second state, where the second state means keeping the SOC working normally, turning off the screen backlight, and cutting off the power supply of peripheral devices.

[0081] In the second state, the SOC can operate normally, the screen backlight is turned off, and peripheral devices are powered off.

[0082] If the user needs to use the car again after temporarily parking and powering off, the SOC can be used directly, saving the time of waiting for the SOC to restart.

[0083] Step 204, start timing when the vehicle computer system is in the second state, and obtain the state information of the electric vehicle in real time during the timing process.

[0084] If the user parks the car for a long time, the static power consumption of keeping the SOC working normally for a long time will be large, so the car system needs to cut off the power supply of the SOC.

[0085] In order to determine whether the user is parking temporarily or for a long time, the vehicle system needs to obtain the status information of the tram in real time within a period of time and make a judgment based on the status information. The status information can be set according to actual needs and is not limited here.

[0086] Step 205, determining whether to control the vehicle system to enter a network sleep state according to the state information, where the network sleep state means cutting off the power of the SOC and the screen.

[0087] Before the timing ends, the vehicle system judges the status information obtained each time. If the judgment result is to continue to maintain the second state, the timing will continue; if the judgment result is to control the vehicle system to enter other states, the timing will end. If the vehicle system is still in the second state at the end of the timing, it is determined that the user is parking for a long time. At this time, the vehicle system is controlled to enter the network dormant state, that is, the power supply of the SOC and the screen is cut off.

[0088] Specifically, determining whether to control the vehicle system to enter the network dormant state according to the state information may include:

[0089] (1) When the timing has not ended, detect whether the status information obtained each time satisfies the first preset condition, the second preset condition or the third preset condition; if the status information satisfies the first preset condition, control the vehicle computer system to maintain the second state; if the status information satisfies the second preset condition, control the vehicle computer system to enter the first state; if the status information satisfies the third preset condition, control the vehicle computer system to enter the third state, and the third state means keeping the SOC, screen and peripheral devices working normally.

[0090] The step of detecting whether the status information satisfies the first preset condition may include:

[0091] (a) When the status information indicates the working time of the vehicle computer system after being awakened, it is detected whether the working time exceeds a first time. If the working time does not exceed the first time, it is determined that the first preset condition is met.

[0092] The vehicle system can count the working time after being awakened and compare the working time with the first time; if the working time exceeds the first time, it is determined that the first preset condition is not met; if the working time does not exceed the first time, it is determined that the first preset condition is met. The first time can be set according to actual needs, such as 1 minute.

[0093] Optionally, in addition to detecting whether the working time exceeds the first time duration, the vehicle system can also detect whether the operating system has completed initialization. If the working time exceeds the first time duration and the operating system has completed initialization, it is determined that the first preset condition is not met; if the working time does not exceed the first time duration and the operating system has not completed initialization, it is determined that the first preset condition is met.

[0094] (b) When the status information indicates that the door lock status message does not change for a first duration, detecting whether the first duration exceeds a second duration; if the first duration does not exceed the second duration, determining that the first preset condition is satisfied.

[0095] The door lock status message is used to indicate the door lock status, which can be an open state or a closed state. The door lock status message includes the left door status (LDCM_LeftLockMotoStatus) and the right door status (RDCM_RightLockMotoStatus).

[0096] The vehicle system can count the first duration of the door lock status message without change, and compare the first duration with the second duration; if the first duration exceeds the second duration, it is determined that the first preset condition is not met; if the first duration does not exceed the second duration, it is determined that the first preset condition is met. The second duration can be set according to actual needs, such as 1 minute.

[0097] (c) When the status information indicates that the second duration of the Unified Diagnostic Services (UDS) message has not been received, detecting whether the second duration exceeds a third duration; if the second duration does not exceed the third duration, determining that the first preset condition is met.

[0098] All controllers on the bus of the tram will send out UDS messages when they are upgraded via Over The Air (OTA). The UDS messages can be used to determine whether the controllers on the bus are upgrading their software.

[0099] The vehicle system can count the second duration of not receiving the UDS message, and compare the second duration with the third duration; if the second duration exceeds the third duration, it is determined that the first preset condition is not met; if the second duration does not exceed the third duration, it is determined that the first preset condition is met. The third duration can be set according to actual needs, for example, set to 10 seconds.

[0100] (d) When the status information indicates that the state is not in the OTA upgrade state or the upgrade message has not been received for a third duration, detecting whether the third duration exceeds a fourth duration; if the third duration does not exceed the fourth duration, determining that the first preset condition is met.

[0101] The vehicle system can count the third duration of the vehicle networking intelligent terminal (Telematics Box, T-Box) not being in the OTA upgrade state or not receiving the upgrade message, and compare the third duration with the fourth duration; if the third duration exceeds the fourth duration, it is determined that the first preset condition is not met; if the third duration does not exceed the fourth duration, it is determined that the first preset condition is met. The fourth duration can be set according to actual needs, for example, set to 10 seconds.

[0102] Among them, detecting whether the status information satisfies the second preset condition may include: when the status information indicates a fourth duration of not being in the charging state, detecting whether the fourth duration exceeds a fifth duration; if the fourth duration does not exceed the fifth duration, determining that the second preset condition is satisfied.

[0103] The vehicle system can count the fourth duration of not being in the charging state, and compare the fourth duration with the fifth duration; if the fourth duration exceeds the fifth duration, it is determined that the second preset condition is not met; if the fourth duration does not exceed the fifth duration, it is determined that the second preset condition is met. The fifth duration can be set according to actual needs, for example, set to 10 seconds.

[0104] The detecting whether the state information satisfies the third preset condition may include: when the state information indicates that a power-on signal is received, determining that the third preset condition is satisfied.

[0105] (2) When the timing ends and the status information obtained each time does not meet the first preset condition, the second preset condition and the third preset condition, the vehicle system is controlled to enter the network dormant state.

[0106] Step 206, when the vehicle computer system is in a network dormant state, obtain the status information of the electric vehicle in real time.

[0107] The status information may be set according to actual needs and is not limited here.

[0108] Step 207: Determine the type of wake-up condition satisfied by the vehicle system according to the status information.

[0109] Specifically, determining the type of wake-up condition satisfied by the vehicle system according to the status information may include:

[0110] (1) When the status information indicates that a power-on signal is received, it is determined that the vehicle system meets the first type of wake-up condition, and the first type of wake-up condition corresponds to the third state.

[0111] Among them, the third state refers to keeping the SOC, screen and peripheral devices working normally.

[0112] (2) When the status information indicates that the electric vehicle is in a charging state, it is determined that the vehicle system meets the second type of wake-up condition, and the second wake-up condition corresponds to the first state.

[0113] (3) When the status information indicates that an application message or a network management message is received and the electric vehicle is not in a charging state, it is determined that the vehicle system meets the third type of wake-up condition, and the third type of wake-up condition corresponds to the second state.

[0114] Step 208, controlling the vehicle system to enter the corresponding first state, second state or third state according to the type of the wake-up condition, and the third state means keeping the SOC, the screen and the peripheral devices working normally.

[0115] To summarize, the power-on and power-off management method of the vehicle system provided in the embodiment of the present application, when receiving the power-off signal, if the electric vehicle is in a charging state, the SOC is kept working normally, the screen is lit to display the charging information, and the power supply of the peripheral devices is cut off; if the electric vehicle is not in a charging state, the SOC is kept working normally, the backlight of the screen is turned off, and the power supply of the peripheral devices is cut off. In these two states, the SOC in the vehicle system works normally. If the user temporarily stops the car and powers off the car and uses it again, the time waiting for the SOC to restart can be saved.

[0116] The timing starts when the vehicle system is in the second state, and the status information of the tram is obtained in real time during the timing process; according to the status information, it is determined whether to control the vehicle system to enter the network sleep state. The network sleep state means cutting off the power supply of the SOC and the screen. In this way, after the user parks the vehicle for a period of time, the static power consumption of the tram when it is not used for a long time can be reduced to avoid unnecessary energy loss.

[0117] The vehicle computer system can smoothly switch between the first state, the second state and the network sleep state, realizing multi-level power state management of the vehicle computer system.

[0139] Determine the type of wake-up condition satisfied by the vehicle computer system according to the status information;

[0140] The vehicle system is controlled to enter the corresponding first state, second state or third state according to the type of wake-up condition. The third state means keeping the SOC, screen and peripheral devices working normally.

[0141] In an optional embodiment, the third management module 350 is further configured to:

[0145] To summarize, the power-on and power-off management device of the vehicle system provided in the embodiment of the present application, when receiving a power-off signal, if the electric vehicle is in a charging state, keeps the SOC working normally, lights up the screen to display charging information, and cuts off the power of peripheral devices; if the electric vehicle is not in a charging state, keeps the SOC working normally, turns off the screen backlight, and cuts off the power of peripheral devices. In both states, the SOC in the vehicle system works normally. If the user temporarily stops the car and powers off the car and uses it again, the time waiting for the SOC to restart can be saved.

[0146] The timing starts when the vehicle system is in the second state, and the status information of the tram is obtained in real time during the timing process; according to the status information, it is determined whether to control the vehicle system to enter the network sleep state. The network sleep state means cutting off the power supply of the SOC and the screen. In this way, after the user parks the vehicle for a period of time, the static power consumption of the tram when it is not used for a long time can be reduced to avoid unnecessary energy loss.

[0147] The vehicle computer system can smoothly switch between the first state, the second state and the network sleep state, realizing multi-level power state management of the vehicle computer system.
