[0030] Embodiment 1

[0031] Figure 1A flowchart of a vehicle sleep control method is provided for the first embodiment of the present invention. This embodiment is applicable to the sleep control of a vehicle when the power is off. The method can be executed by a vehicle sleep control device. The vehicle sleep control device can be implemented in the form of hardware and / or software. The vehicle sleep control device can be configured in a vehicle, and the vehicle includes an automatic transmission control unit (Transmission Control Unit, TCU), a domain control unit (Domain Control Unit, DCU) and a battery management system (Battery Management System, BMS).

[0032] like Figure 1 As shown, the method includes:

[0033] S110, in response to the state of the self-reset button being a closed state.

[0034] In this embodiment, the self-reset button (ie, Adaptive-Cruise-Control, ACC) can be understood as a switch button of a vehicle key. The state can be understood as a state used to characterize whether the vehicle is powered on.

[0035] It is understandable that, usually when the car is parked and the engine is turned off, the key is in the LOCK position. In this position, the vehicle circuit is disconnected, the entire vehicle is powered off, the steering wheel is locked, and the ACC state is off. When the key is in the ACC position, the ACC state corresponds to the on state, and some of the vehicle's electrical equipment is powered on, such as the radio, audio, etc., but other parts of the vehicle are not powered on.

[0036] Specifically, the state of the self-reset button can be determined by the TCU, DCU and BMS respectively, in response to the state of the self-reset button being a closed state.

[0037] Among them, ACC is only a self-reset button, so ACC only wakes up from shallow sleep. The ACC power-off judgment adopts the reading of the ACC status of DCU (judging DCU-8BYTE1 (instrument status) BIT7). When DCU-8BYTE1 (instrument status) BIT7 is 1, ACC is powered on, and when DCU-8BYTE1 (instrument status) BIT7 is 0, ACC is powered off. When BMS does not receive DCU-8 message for 20 seconds, it is considered that DCU is offline and ACC is powered off.

[0038] S120: Perform a first control on the vehicle according to the first self-state information and the platform command monitoring result through the TCU.

[0039] In this embodiment, the first self-state information can be understood as the result of the TCU detecting its own state, for example, it can include detecting the duration of its own power-on, etc. The vehicle can be equipped with a platform in the form of a software APP, etc., through which control instructions can be remotely issued to the vehicle. The command monitoring result can be understood as the monitoring result used to determine whether there is a control command. The first control can be understood as the control of the vehicle by the TCU.

[0040] Specifically, when the state of the self-reset button is off, the TCU can control itself to enter the low power consumption mode according to the first self-state information. Since the TCU also includes a GPS unit and can be connected to the network, the GPS unit in the TCU can be connected to the network to monitor the platform command, and determine whether to turn on the power of the whole vehicle to issue the command based on the platform command monitoring result, so as to achieve the first control of the vehicle.

[0041] S130, performing a second control on the vehicle according to the second self-state information and the first state detection result of the self-reset button through the DCU.

[0042] In this embodiment, the second self-state can be understood as the result of the DCU detecting its own state, for example, it can include detecting the duration of its own power-on, etc. Since there may be a situation where ACC is turned on, the first state detection result can be understood as the result of re-detecting the on and off states of ACC. The second control can be understood as the control of the vehicle by the DCU.

[0043] Specifically, when the state of the self-reset button is off, the DCU can control itself to enter the low power consumption mode according to the second self-state information, and continue to detect the state of the self-reset button after entering the low power consumption mode to obtain the first state detection result, and subsequently control the vehicle through the change of the first state detection result.

[0044] S140. Performing a third control on the vehicle according to the third self-state information and the second state detection result of the self-reset button through the BMS.

[0045] In this embodiment, the third self-state can be understood as the result of the BMS detecting its own state, for example, it can include the detection of the duration of its own power-on, and the results of the detection of the power-on condition and the power condition. The second state detection result can be understood as the BMS's re-detection result of the on and off state of ACC. The third control can be understood as the BMS's control of the vehicle.

[0046] Specifically, when the state of the self-reset button is off, the BMS can determine the overall mode entered by the vehicle according to the battery condition in the third self-state information, which may include, for example, a shallow sleep mode with a better battery condition and a deep sleep mode with a poorer battery condition. In the shallow sleep mode, the BMS can control itself to enter the low power mode based on the third self-state information, and continue to detect the state of the self-reset button after entering the low power mode to obtain the second state detection result, and subsequently control the vehicle through changes in the second state detection result. In the deep sleep mode, the power of the entire vehicle can be directly turned off, and the vehicle enters an extremely low power consumption mode, waiting for charging activation.

[0047] The technical solution of the embodiment of the present invention is applied to a vehicle, which includes an automatic transmission control unit TCU, a domain control unit DCU and a battery management system BMS. In response to the state of the self-reset button being in the off state, the TCU performs a first control on the vehicle according to the first self-state information and the platform command monitoring result; the DCU performs a second control on the vehicle according to the second self-state information and the first state detection result of the self-reset button; and the BMS performs a third control on the vehicle according to the third self-state information and the second state detection result of the self-reset button. After parking, the sleep strategy is determined and controlled comprehensively by the TCU, DCU and BMS, and the sleep state is awakened by the unit with lower power consumption in the TCU listening to the platform command. Flexible control of the sleep state is achieved, parking power consumption is reduced, and the over-discharge problem after the vehicle is parked is solved.

[0048] Embodiment 2

[0049] Figure 2 This is a flow chart of a vehicle sleep control method provided by Embodiment 2 of the present invention. This embodiment is a refinement of the above embodiment. Figure 2 As shown, the method includes:

[0050] S201, in response to the state of the self-reset button being a closed state.

[0051] S202: When the first timing sub-information in the first self-state information reaches a preset first timing duration, the TCU determines that the self-CAN bus function is turned off, and the self is controlled to enter a first low power consumption mode.

[0052] In this embodiment, the first timing sub-information can be understood as being used to record the duration of this power-on, for example, each time the self-reset button is switched from off to on, it is used as the start time of the TCU timing, thereby determining the first timing sub-information. The preset first timing duration can be understood as the preset time for the TCU to enter the sleep mode, for example, it can be 24 hours, etc. The CAN bus function can be understood as the function of transmitting data via the CAN bus. The first low power mode can be understood as the low power mode of the TCU, for example, a low power keep-alive mode, and the corresponding parameter is less than 48V / 1mA.

[0053] Specifically, the TCU obtains the first timing sub-information in the first self-state information, and compares the first timing sub-information with the preset first timing duration to determine whether the entry into the first low-function mode can be triggered. When the first timing sub-information reaches the preset first timing duration (for example, 24 hours), the TCU can turn off its own CAN bus function and control itself to enter the first low-power consumption mode, for example, hibernation at a power consumption of 48V / 1mA.

[0054] S203. When the TCU determines that the vehicle is in the first low power consumption mode and the platform command monitoring result indicates that there are commands to be sent, the vehicle power is turned on according to the preset turn-on time, the state of the self-reset button is turned on, and the CAN bus data transmission is activated to synchronize the commands to be sent through the CAN bus.

[0055] In this embodiment, the instruction to be sent can be understood as an instruction for the platform to transmit and enable the vehicle to complete a specific function. The preset opening time can be understood as the power-on time of the vehicle power supply, for example, it can be powered on for 5 seconds.

[0056] Specifically, when the TCU determines that the vehicle is in the first low power consumption mode and the platform command monitoring result indicates that there are instructions to be sent, the power of the vehicle can be turned on according to the preset opening time. At this time, the state of the self-reset button automatically changes to the on state, and the TCU can activate the CAN bus data transmission and synchronize the instructions to be sent through the CAN bus.

[0057] S204. When the second timing sub-information in the second self-state information reaches the preset second timing duration, the DCU determines that the self-CAN bus function is turned off, the Bluetooth function is turned off, and the self is controlled to enter the second low power consumption mode.

[0058] In this embodiment, the second timing sub-information can be understood as being used to record the duration of this power-on, for example, each time the self-reset button is switched from off to on, it is used as the start time of the DCU timing, thereby determining the second timing sub-information. The preset second timing duration can be understood as the preset time for the DCU to enter the sleep mode, for example, it can be 24 hours, etc., which can be the same as or different from the first timing duration and the third timing duration, and can be set according to actual needs. The second low power consumption mode can be understood as the low power consumption mode of the DCU, for example, it can sleep at a power consumption of 48V / 0.5mA.

[0059] Specifically, the DCU obtains the second timing sub-information in the second self-state information, and compares the second timing sub-information with the preset second timing duration to determine whether the entry into the second low-function mode can be triggered. When the second timing sub-information reaches the preset second timing duration (for example, 24 hours), the DCU can turn off its own CAN bus function and control itself to enter the second low power consumption mode, for example, hibernation with a power consumption of less than 48V / 0.5mA.

[0060] S205. When the DCU determines that the system is in the second low power consumption mode and the first state detection result of the self-reset button is the on state, the system turns on its own CAN bus function, turns on the Bluetooth function, turns on the senseless function, receives and executes the platform instructions transmitted through the CAN bus, and continues to detect the state of the self-reset button.

[0061] In this embodiment, the senseless function can be understood as a function in which the system can automatically complete tasks without the user having to perform obvious perception or dare in a specific operation or scenario, such as remote monitoring and control through the senseless function, that is, controlling the vehicle air conditioning, doors and windows, remote start or shutdown, etc. through the APP. The platform command is the command that the DCU can respond to in the above-mentioned commands to be sent transmitted by the TCU.

[0062] Specifically, when the DCU determines that it is in the second low power consumption mode and the first state detection result of the self-reset button is on (for example, the self-reset button is turned on when the TCU issues a pending instruction), it turns on its own CAN bus function, turns on the Bluetooth function and the senseless function to respond to the platform instruction, receives the platform instruction transmitted through the CAN bus and executes it, and continues to detect the state of the self-reset button.

[0063] S206. Determine, through the BMS, a vehicle sleep mode of the vehicle according to the battery status sub-information in the third self-status information. The vehicle sleep mode includes a deep sleep mode and a shallow sleep mode.

[0064] In this embodiment, the battery status sub-information can be understood as a state related to the battery, such as the state of the charge and discharge current, the voltage of the battery cell, and the battery state of charge (SOC) value. The vehicle sleep mode can be understood as a control mode for the entire vehicle. In this embodiment, the deep sleep mode can be understood as a sleep mode under conditions of low power or abnormalities, and the charging and discharging MOS are both disconnected. The shallow sleep mode can be understood as a sleep mode that can also achieve specific functions, such as the sentinel mode, in which the BMS is in shallow sleep and the charging and discharging MOS are both closed).

[0065] Specifically, the BMS may judge the vehicle sleep mode according to the battery status sub-information in the third self-status information and the set conditions in combination with the battery status sub-information, and determine the vehicle sleep mode corresponding to the vehicle.

[0066] Exemplarily, the battery status sub-information includes the charge and discharge current, short circuit protection, battery cell voltage and SOC value. When there is no charge and discharge current and no short circuit protection, and the cell voltage is greater than the deep sleep voltage and SOC>5%, in order to ensure accuracy, the sleep delay judgment is first entered. If this state lasts for a specific number of seconds (for example, 20s), it is judged as a shallow sleep mode. If the cell voltage is less than or equal to the deep sleep voltage or SOC<=5%, and the duration of this state reaches the sleep delay (for example, 20s), or if there is a fault, it is judged as a deep sleep mode.

[0067] S207. When the BMS determines that the vehicle sleep mode is the shallow sleep mode, the vehicle is thirdly controlled according to the third preset timing duration, the third timing sub-information in the third self-state information, and the second state detection result of the self-reset button.

[0068] In this embodiment, the third timing duration can be understood as the duration for recording the current power-on, for example, each time the self-reset button is switched from off to on, it is used as the start time of the BMS timing, so as to determine the third timing sub-information. The preset third timing duration can be understood as the preset time for the BMS to enter the sleep mode, for example, it can be 24 hours, etc., which can be the same as or different from the first timing duration and the second timing duration, and can be set according to actual needs.

[0069] Specifically, when the BMS determines that the vehicle sleep mode is a shallow sleep mode, the BMS can obtain the third timing sub-information in the third self-state information, and compare the third timing sub-information with the preset third timing duration to determine whether the entry into the second low-function mode can be triggered. When the second timing sub-information reaches the preset second timing duration (for example, 24 hours), the DCU can turn off its own CAN bus function and control itself to enter the second low power consumption mode, for example, sleep with a power consumption of less than 48V / 0.5mA.

[0070] Specifically, when the BMS determines that the vehicle sleep mode is the shallow sleep mode, the BMS can perform the third control on the vehicle according to the preset third timing duration, the third timing sub-information in the third self-state information, and the second state detection result of the self-reset button.

[0071] Further, based on the above embodiment, the steps of performing the third control on the vehicle according to the preset third timing duration, the third timing information in the third self-state information and the second state detection result of the self-reset button can be refined as follows:

[0072] When the third timing information reaches the preset third timing duration, the CAN bus function is turned off and the device is controlled to enter the third low power consumption mode. When the second state detection result of the self-reset button is the on state, the CAN bus function is turned on and data transmission is turned on, and the state of the self-reset button is continued to be detected.

[0073] In this embodiment, the third low power consumption mode may be understood as a low power consumption mode of the DCU, for example, the DCU may sleep with a power consumption less than 48V / 0.5mA.

[0074] Specifically, when the third timing information reaches the preset third timing duration, the BMS can turn off its own CAN bus function and control itself to enter the third low power mode, for example, to sleep with a power consumption of less than 48V / 0.5mA. When the second state detection result of the self-reset button is the on state, turn on its own CAN bus function and start data transmission, and continue to detect the state of the self-reset button.

[0075] S208. When the vehicle sleep mode is determined to be a deep sleep mode through the BMS, the power supply of the entire vehicle is turned off, and the vehicle is controlled to enter the factory mode.

[0076] In this embodiment, the factory mode can be understood as a special operating or diagnostic mode that allows technicians or engineers to access detailed system information and settings in the vehicle's electronic control unit (ECU) for obtaining detailed system status information during automobile production, maintenance or testing.

[0077] Specifically, when the BMS determines that the vehicle sleep mode is a deep sleep mode, the BMS can shut down the power of the entire vehicle and control the vehicle to enter the factory mode.

[0078] Optionally, after performing the third control on the vehicle according to the preset third timing duration, the third timing sub-information in the third self-state information, and the second state detection result of the self-reset button, the method may further include:

[0079] When the preset wake-up interval is reached, the BMS wakes itself up according to the preset wake-up time and obtains the current battery status; based on the current battery status, the current vehicle sleep mode is determined, and the vehicle is subjected to the fourth control.

[0080] In this embodiment, the preset wake-up interval duration can be understood as the time interval of the scheduled wake-up, for example, it can be 2 hours. The preset wake-up duration can be understood as the duration of the controlled wake-up, for example, it can be 1 minute of wake-up. The current battery status can be understood as the status information of the battery at the time of wake-up. The current vehicle sleep mode can be understood as the sleep mode determined at the time of wake-up.

[0081] Specifically, after the third control of the vehicle is performed according to the preset third timing duration, the third timing sub-information in the third self-state information, and the second state detection result of the self-reset button, that is, in shallow sleep mode, when the preset wake-up interval duration is reached, the BMS can time the sleep duration. When the sleep duration reaches the preset wake-up interval duration (for example, timed wake-up every 2 hours), the BMS can wake itself up according to the preset wake-up duration and obtain the current battery status. The BMS can determine the current vehicle sleep mode based on the current battery status according to the above judgment method. The current vehicle sleep mode is still divided into shallow sleep mode and deep sleep mode. Since it is currently in shallow sleep mode, no control is required. After the wake-up duration reaches the preset wake-up duration, it enters shallow sleep mode again. If it is judged to be deep sleep mode, the power of the entire vehicle is turned off and enters factory mode. And in deep sleep mode, the vehicle can only be activated by charging.

[0082] The technical solution of the embodiment of the present invention is that after the power is cut off and the vehicle is parked, the TCU is used to control its own functions and low-power consumption mode, and the platform instructions are monitored with lower power consumption. After receiving the platform instructions, the ACC and its own parts are awakened to realize the functions of forwarding and responding to the platform instructions, so as to realize flexible control of its own state and respond to the platform instructions with lower power consumption. The DCU is used to control its own functions and low-power consumption mode. When the state of the self-reset button is not turned on, the bus function is started, and when the platform instruction is received, the function of responding to the platform instruction is turned on, so as to realize flexible control of its own sleep state and respond to the platform instruction with lower power consumption. The BMS determines the vehicle sleep mode of the whole vehicle through the state of the battery, and controls its own functions and the whole vehicle based on the vehicle sleep mode, so as to realize automatic judgment and switching of the vehicle sleep mode. Flexible control of the sleep state is realized, the parking power consumption is reduced, and the problem of over-discharge after the vehicle is parked is solved.

[0083] Exemplarily, this method is demonstrated with a specific example, and the parameters are only used as examples and are not specifically limited. Figure 3 This is an example flow chart of a vehicle sleep control method provided in Embodiment 2 of the present invention, such as Figure 3 As shown, the steps may include:
