[0044] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0045] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation.

[0046] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0047] See also Figures 1 to 4 The present invention proposes a method, system, device, and medium for controlling vehicle driving energy consumption. These methods can be applied to the field of intelligent driving vehicles. Under different driving scenarios, they can dynamically adjust the operating power consumption of high-computing chips, sensor operating power consumption, and power supply power consumption, thereby reducing vehicle driving energy consumption and improving vehicle endurance and reliability during driving. A detailed description of these methods is provided below using specific embodiments.

[0048] See also Figure 1 In one embodiment of the present invention, the present invention provides a connection block diagram of vehicle internal modules, which may include a power control module 10, a process control module 20 and a thermal control module 30.

[0049] In one embodiment of the present invention, the battery control module 10 is configured to power on or off each domain controller 120 and each sensor 110 on the vehicle, depending on the functional mode. The battery control module 10 may also determine status information for multiple domain controllers 120 based on the functional mode. The status information for a domain controller 120 may be power-on information (power-on state) or power-off information (power-off state). The domain controller 120 is a system-on-chip (SoC).

[0050] For example, the functional status and usage scenarios of the vehicle are obtained, and the corresponding functional mode of the vehicle is determined based on the functional status and usage scenarios. The functional status of the vehicle represents the real-time operating status of the vehicle's hardware and software, such as sensor status, computing unit load, and energy status. The usage scenarios of the vehicle represent the external environment in which the vehicle is located and user needs, such as driving scenarios, user instructions, and environmental conditions. Functional modes include at least default mode, sentry mode, full-function mode, calibration mode, over-the-air upgrade mode, function suppression mode, data desensitization mode, and / or low-power mode.

[0051] For example, the default mode represents the state when the vehicle is initially powered on or the driver is just about to use the vehicle. Sentry mode represents the state when the driver locks the vehicle and turns on surrounding monitoring. Full-function mode indicates that all sensors 110 and system-on-chip (SoC) are turned on normally. Full-function mode is the state in which all intelligent driving functions are available. Calibration mode is the factory calibration scenario. Over The Air Mode (OTA) mode is the offline upgrade state. Data desensitization mode indicates the desensitization working state of vehicle data in idle time, when the intelligent driving function is not running and is not turned on and can be turned on. Low power consumption mode indicates that some intelligent driving functions are available, and most of them are restricted and cannot be used. It is a mode automatically selected by the driver or when the battery of the vehicle is low. Function suppression mode means that under certain conditions (such as when the system detects potential risks or the user actively selects), some high-level autonomous driving functions are temporarily restricted, but the basic sensors 110 and computing units are kept running.

[0052] For example, the sensor 110 may include a laser radar (Lidar), an around view camera (AVM, Around View Monitor), a front view camera, a rear view camera, a side view camera, and a millimeter wave radar, etc.

[0053] In one embodiment of the present invention, the process control module 20 is connected to the battery control module 10, and is used to start or shut down multiple processes corresponding to the domain controller 120 according to the functional mode when the battery control module 10 supplies power to the domain controller 120.

[0054] In one embodiment of the present invention, the process control module 20 dynamically obtains the current vehicle functional mode (such as default mode, sentry mode, low power mode, etc.) through the vehicle bus (such as CANFD / CANXL). When the battery control module 10 supplies power to the domain controller 120, the process control module 20 dynamically manages multiple processes running on the domain controller 120 based on intelligent decision-making in the functional mode, and pulls up (activates, starts) or shuts down (doesn't, shuts down) specific process groups as needed, thereby achieving refined energy consumption control and computing power optimization.

[0055] Specifically, the thermal control module 30 is connected to the battery control module 10 and can obtain the coolant temperature and the temperature of the domain controller 120 through the temperature sensor. The thermal control module 30 can control the output flow of the coolant according to the function mode, the coolant temperature and the temperature of the domain controller 120.

[0056] For example, the thermal control module 30 obtains the current vehicle functional mode via a vehicle communication network (such as CANFD or Ethernet). Simultaneously, the thermal control module 30 monitors the coolant temperature and the chip temperature of the domain controller 120 in real time. Based on the functional mode, coolant temperature, and domain controller temperature, the module makes intelligent decisions and dynamically adjusts the speed of the water pump motor 310. This allows for dynamic adjustment of the coolant flow rate to ensure that the domain controller 120 operates within the optimal temperature range while minimizing cooling system energy consumption.

[0057] As can be seen, in this embodiment, first, the sensor 110 and domain controller 120 can be dynamically powered on and off based on the vehicle's different functional modes. Second, when the vehicle's domain controller 120 is powered on, multiple processes corresponding to the domain controller 120 can be controlled to be enabled or disabled based on the vehicle's functional mode, thereby saving energy consumption. Finally, the speed of the water pump motor 310 is controlled based on the vehicle's functional mode, coolant temperature, and the temperature of the domain controller 120. Under low load conditions, the speed of the water pump motor 310 is reduced to 30%, reducing cooling system energy consumption by 40%.

[0058] The following specific embodiments will be used to dynamically power on / off the above-mentioned sensor 110 and domain controller 120, and to start (activate) or shut down (sleep) multiple processes corresponding to the domain controller 120, and to dynamically adjust the speed of the water pump motor 310, thereby realizing the processing process of dynamically adjusting the coolant flow rate, and a detailed analysis will be conducted.

[0059] See also Figure 2 In one embodiment of the present invention, the present invention provides a method for controlling vehicle driving energy consumption, which may include the following steps.

[0060] Step S10: Acquire the vehicle's functional mode, coolant temperature, and vehicle SoC temperature in real time.

[0061] Specifically, the vehicle's operating status and surrounding environment information may be obtained, and the corresponding functional mode of the vehicle may be determined based on the operating status and surrounding environment information. The vehicle's coolant temperature and the temperature of the domain controller 120 may be detected by a temperature sensor, thereby obtaining the coolant temperature and the temperature of the domain controller 120.

[0062] Specifically, the state information of the domain controller may be power-on information (power-on state) or power-off information (power-off state).

[0063] Step S20: According to the functional mode, the vehicle SoC and the sensors in the vehicle are controlled accordingly for power supply, and the output flow of the coolant is calculated according to the coolant temperature and the vehicle SoC temperature.

[0064] In one embodiment of the present invention, in step S20, the step of performing corresponding power supply control on the vehicle SoC and each sensor in the vehicle according to the functional mode may include step S210 and step S220.

[0065] Step S210: In a preset power-on mapping table, select the power supply control information corresponding to the vehicle SoC and each sensor in the vehicle according to the functional mode; wherein the power-on mapping table includes the power supply control information of the vehicle SoC and each sensor in the vehicle corresponding to each functional mode.

[0066] Step S220: Control the power supply of the corresponding vehicle SoC and the sensors in the vehicle according to the selected power supply control information.

[0067] Specifically, in step S210, the step of selecting the power supply control information corresponding to the vehicle SoC according to the functional mode may include step S211, step S212 and step S213.

[0068] Step S211: Determine the type of the functional mode.

[0069] Step S212: When the functional mode is the full-function mode, the calibration mode, the data desensitization mode, the over-the-air upgrade mode, or the function suppression mode, power supply control information for powering the vehicle SoC is selected.

[0070] Step S213: When the functional mode is the default mode, the sentry mode or the low power consumption mode, power supply control information for not supplying power to the vehicle SoC is selected.

[0071] Referring to Table 1, in one embodiment of the present invention, the domain controller 120 on the vehicle is powered on when the vehicle is in function suppression mode, full function mode, calibration mode, data desensitization mode, or over-the-air upgrade mode. The domain controller 120 on the vehicle is not powered on when the vehicle is in default mode, sentry mode, or low power mode.

[0072] Specifically, in step S210, the step of selecting the power supply control information corresponding to each sensor in the vehicle according to the functional mode includes step S214, step S215 and step S216.

[0073] Step S214: Determine the type of the functional mode.

[0074] Step S215: When the functional mode is the full-function mode or the calibration mode, power supply control information for supplying power to each sensor in the vehicle is selected.

[0075] Step S216: When the functional mode is the default mode, select power supply control information for not supplying power to the sensors of the vehicle.

[0076] Specifically, as shown in Table 1, when the vehicle is in different functional modes, different sensors 110 and domain controllers 120 can be powered on or off respectively.

[0077] Table 1. Vehicle function mode corresponding to sensor and domain controller power-on mapping table

[0078]

[0079] In one embodiment of the present invention, in step S20, the step of calculating the output flow rate of the coolant according to the functional mode and the coolant temperature and the vehicle SoC temperature may include step S230, step S240 and step S250.

[0080] Step S230: Determine the type of the functional mode.

[0081] Step S240: When the functional mode is full-function mode, calibration mode, data desensitization mode, over-the-air upgrade mode, or function suppression mode, the output flow of the coolant is calculated according to the coolant temperature and the vehicle SoC temperature in the preset first flow mapping table.

[0082] Step S250: When the functional mode is the default mode, sentinel mode, or low power mode, the output flow of the coolant is calculated according to the coolant temperature and the vehicle SoC temperature in a preset second flow mapping table; the second flow mapping table is different from the first flow mapping table.

[0083] Specifically, the system controls the operation of the vehicle's water pump motor, ensuring that it controls the flow of coolant according to the corresponding coolant output flow rate. Specifically, intelligent decisions are made based on the functional mode, coolant temperature, and the temperature of the domain controller 120 to dynamically adjust the speed of the water pump motor 310. This allows for dynamic adjustment of the coolant flow rate, ensuring that the domain controller 120 operates within the optimal temperature range while minimizing cooling system energy consumption.

[0084] Specifically, the corresponding coolant output flow rate is selected from the flow mapping table based on the vehicle's functional mode, coolant temperature, and domain controller temperature. The flow mapping tables are shown in Tables 2 and 3. Table 2 is a first flow mapping table that maps the coolant temperature and domain controller temperature to the coolant output flow rate when the domain controller is powered on. Table 3 is a second flow mapping table that maps the coolant temperature and domain controller temperature to the coolant output flow rate when the domain controller is powered off.

[0085] Table 2: First traffic mapping table

[0086]

[0087] Table 3. Second traffic mapping table

[0088]

[0089] Please refer to Table 2 and Table 3. In one embodiment of the present invention, in step S20, the step of establishing the first flow mapping table or the second flow mapping table includes the following steps.

[0090] A plurality of continuous coolant temperature intervals are set, and adjacent coolant temperature intervals are divided into intervals with preset critical temperature values ​​as dividing points.

[0091] In each of the coolant temperature intervals, a plurality of continuous domain controller temperature intervals are set, and adjacent domain controller temperature intervals are divided into intervals with preset critical temperature values ​​as dividing points; a mapping relationship is established between the coolant temperature interval and all its corresponding domain controller temperature intervals, and each mapping relationship is set with a corresponding coolant output flow.

[0092] The flow mapping table is established by combining each coolant temperature interval, the domain controller temperature interval corresponding to each coolant temperature interval, and the corresponding coolant output flow.

[0093] Specifically, referring to Tables 2 and 3, in one embodiment of the present invention, multiple continuous coolant temperature intervals may be set. For example, as shown in Table 2, the multiple continuous coolant temperature intervals may be T≤40°C, 40°C<T≤50°C, 50°C<T≤57°C, and 57°C<T.

[0094] In each coolant temperature interval, multiple continuous domain controller 120 temperature intervals are set, and a mapping relationship is established between the coolant temperature interval and all the corresponding multiple continuous domain controller temperature intervals, and each mapping relationship is set with a corresponding coolant output flow rate.

[0095] For example, as shown in Table 2, when the coolant temperature range is T≤40°C, the domain controller 120 temperature range can be T SOC <105℃、105℃≤T SOC <109℃ and 109℃≤T SOC .

[0096] As shown in Table 2, when the coolant temperature range is 40°C < T ≤ 50°C, the domain controller 120 temperature range can be T SOC <106℃、106℃≤T SOC <110℃ and 110℃≤T SOC .

[0097] As shown in Table 2, when the coolant temperature range is 50°C < T ≤ 57°C, the domain controller 120 temperature range can be T SOC <107℃、107℃≤T SOC <111℃ and 111℃≤T SOC .

[0098] As can be seen, when the coolant temperature ranges are different, the corresponding domain controller 120 temperature ranges are also divided differently. That is, each coolant temperature range corresponds to a group of domain controller 120 temperature ranges. Under each coolant temperature range, a mapping relationship is established between the coolant temperature range and all corresponding domain controller 120 temperature ranges, and each mapping relationship is set with the corresponding coolant output flow rate.

[0099] For example, in Table 2, when the coolant temperature range is T≤40°C, and the domain controller 120 temperature range is T SOC When the temperature range of the coolant is 40℃<T≤50℃, when the temperature range of the domain controller 120 is T SOC When the temperature is less than 106℃, the corresponding coolant output flow rate is 1L / min.

[0100] By setting the coolant temperature range corresponding to the coolant, setting the domain controller 120 temperature range corresponding to the domain controller 120, and setting the corresponding coolant output flow based on the coolant temperature range domain controller 120 temperature range, refined thermal energy management can be achieved, thereby effectively controlling the energy consumption of the water pump corresponding to the cooling system.

[0101] A flow mapping table is created for each coolant temperature interval, the domain controller 120 temperature interval corresponding to each coolant temperature interval, and the corresponding coolant output flow rate, for example, the first flow mapping table in Table 2 and the second flow mapping table in Table 3.

[0102] Please refer to Table 2. In one embodiment of the present invention, a first traffic mapping table corresponding to the domain controller 120 being in a powered-on state may be established.

[0103] When the vehicle is in function suppression mode, full function mode, calibration mode, data desensitization mode and over-the-air upgrade mode, the corresponding coolant output flow is selected in the first flow mapping table according to the function mode, coolant temperature and domain controller temperature, and the coolant flow is controlled according to the coolant output flow.

[0104] Please refer to Table 3. In one embodiment of the present invention, a second traffic mapping table corresponding to when the domain controller 120 is not in a powered-on state may be established.

[0105] When the vehicle is in the default mode, sentry mode and low power mode, the output flow of the corresponding coolant is selected in the second flow mapping table according to the functional mode, coolant temperature and the temperature of the domain controller 120, and the coolant flow is controlled according to the output flow of the coolant.

[0106] Step S30, when the functional mode is full-function mode, calibration mode, data desensitization mode, over-the-air upgrade mode or function suppression mode, corresponding process management is performed on the current process.

[0107] In one embodiment of the present invention, step S30 may include step S310 and step S320.

[0108] Step S310: Select corresponding process control information from a preset process control table according to the functional mode; wherein the process control table includes process control information corresponding to each functional mode.

[0109] Step S320: Start or close the corresponding process according to the selected process control information.

[0110] Specifically, in step S310, the step of selecting the process control information corresponding to the current process according to the functional mode includes step S311, step S312, step S313 and step S314.

[0111] Step S311: Determine the type of the functional mode.

[0112] Step S312: When the functional mode is the full-function mode, process control information for starting each process in the vehicle SoC is selected.

[0113] Step S313: When the functional mode is the over-the-air upgrade mode, process control information is selected to start the basic process in the vehicle SoC and close other processes.

[0114] Step S314: When the functional mode is the data desensitization mode, process control information is selected to start the data desensitization process in the vehicle SoC and to close other processes.

[0115] Referring to Table 4, in one embodiment of the present invention, when the vehicle is in function suppression mode, full function mode, calibration mode, data desensitization mode, or over-the-air upgrade mode, that is, when the vehicle's domain controller 120 is powered on, the process control module 20 respectively starts or shuts down multiple processes corresponding to the domain controller 120 in different function modes. In Table 4, a "√" indicates a start (start, run) process, and a blank indicates a shutdown process.

[0116] Table 4. Process control table of domain controller corresponding to vehicle function mode

[0117]

[0118] Specifically, as shown in Table 4, the processes corresponding to the domain controller 120 may include a basic data process (MachineFG), a sensor data analysis process (Sensor FG), a human-computer interaction process (DhuFG), a common process for parking functions (Common FG), a data desensitization and data feedback process (DataInfo FG), a factory end-of-line calibration process (Eol FG), an intelligent driving algorithm process (Driving FG), an intelligent parking algorithm process (Parking FG), a driving function status management process (DrivingFsmFG), and a parking function status management process (ParkingFsmFG).

[0119] See also Figure 3 In one embodiment of the present invention, the present invention proposes a vehicle driving energy consumption control system 100 , which may include an acquisition unit 110 , a first control unit 120 , and a second control unit 130 .

[0120] The acquisition unit 110 is used to acquire the vehicle's functional mode, coolant temperature, and vehicle SoC temperature in real time.

[0121] The first control unit 120 is used to perform corresponding power supply control on the vehicle SoC and various sensors in the vehicle according to the functional mode, and calculate the output flow rate of the coolant according to the coolant temperature and the vehicle SoC temperature.

[0122] The second control unit 130 is used to perform corresponding process management on the current process when the functional mode is the full-function mode, the calibration mode, the data desensitization mode, the over-the-air upgrade mode or the function suppression mode.

[0123] It can be seen that based on the intelligent decision-making of the functional mode, the multiple processes running on the domain controller 120 are dynamically managed, and specific process groups are started (activated) or closed (hibernated) as needed, thereby achieving refined energy consumption control and computing power optimization. Based on the functional mode, coolant temperature and domain controller temperature, intelligent decision-making is made to dynamically adjust the speed of the water pump motor 310, so that the coolant flow can be dynamically adjusted to ensure that the domain controller 120 operates within the optimal temperature range while minimizing the energy consumption of the cooling system. When the vehicle is in a certain functional mode, a certain coolant temperature and a certain domain controller temperature, the output flow of multiple sensors, multiple domain controllers, multiple processes in the domain controller and the coolant is collaboratively controlled to achieve the unity of energy consumption optimization, performance assurance and system reliability.

[0124] See also Figure 4 The present invention proposes an electronic device, the electronic device 200 may include a memory 210, a processor 220 and a bus, and may also include a computer program stored in the memory 210 and executable on the processor 220, such as a vehicle driving energy consumption control program.

[0125] Among them, the memory 210 includes at least one type of readable storage medium, and the readable storage medium includes a flash memory, a mobile hard disk, a multimedia card, a card-type memory (for example, SD or DX memory, etc.), a magnetic memory, a magnetic disk, an optical disk, etc. In some embodiments, the memory 210 can be an internal storage unit of the electronic device 200, such as a mobile hard disk of the electronic device 200. In other embodiments, the memory 210 can also be an external storage device of the electronic device 200, such as a plug-in mobile hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card, etc. equipped on the electronic device 200.
