Figure 2The whole vehicle power consumption coordination management method can be provided by Figure 1 The vehicle controller 101 performs the execution. For example... Figure 2 As shown, the vehicle power consumption coordination management method includes the following steps: Step S201: Obtain the power domain power consumption dataset reported by the power domain master controller in the power domain system, the chassis domain power consumption dataset reported by the chassis domain master controller in the chassis domain system, and the body domain power consumption dataset reported by the body domain master controller in the body domain system; wherein, the power domain system includes a first power domain sub-controller, a second power domain sub-controller, and a third power domain sub-controller; the power domain power consumption dataset includes the first power domain power consumption data corresponding to the first power domain sub-controller, the second power domain power consumption data corresponding to the second power domain sub-controller, and the third power domain power consumption data corresponding to the third power domain sub-controller.

Based on the power consumption dataset in the chassis domain and the power consumption dataset in the body domain, a third inter-domain power consumption coordination management strategy is determined. Based on the power consumption dataset in the body domain, a fourth inter-domain power consumption coordination management strategy is determined.

[0018] The technical solution provided in this application, based on the power domain power consumption dataset, chassis domain power consumption dataset, and body domain power consumption dataset reported by the power domain system, chassis domain system, and body domain system, determines the intra-domain power consumption coordination management strategy and the inter-domain power consumption coordination management strategy, and performs whole-vehicle power consumption coordination management, thereby achieving unified whole-vehicle power consumption coordination management, thereby reducing whole-vehicle power consumption and extending whole-vehicle range and battery life.

[0019] In some embodiments, the intra-domain power consumption coordination management strategy includes a power consumption coordination management strategy within the power domain, a power consumption coordination management strategy within the chassis domain, and a power consumption coordination management strategy within the body domain.

[0020] The power domain power consumption coordination management strategy is a management mechanism for dynamic power consumption distribution of core components such as motors, batteries, engines and high-voltage accessories included in the power domain.

[0021] The chassis domain power consumption coordination management strategy is a management mechanism for dynamic power consumption distribution of core components such as brake systems, suspensions, steering systems and heterogeneous computing units of domain controllers included in the chassis domain.

[0022] The body domain power consumption coordination management strategy is a management mechanism for dynamic power consumption distribution of core components such as comfort control, safety assistance, bus communication and domain controllers in the body domain.

[0023] Based on the power domain power consumption dataset, the chassis domain power consumption dataset and the body domain power consumption dataset, the domain power consumption coordination management strategy is determined, including: Based on the power domain power consumption dataset, the power domain power consumption coordination management strategy for the power domain system is determined; Based on the chassis domain power consumption dataset, the chassis domain power consumption coordination management strategy for the chassis domain system is determined; Based on the body domain power consumption dataset, the body domain power consumption coordination management strategy for the body domain system is determined.

[0024] In some embodiments, the power domain power consumption coordination management strategy includes a first power domain coordination response rule, a second power domain coordination response rule and a third power domain coordination response rule.

[0025] Figure 3 is a system structure schematic diagram of a power domain system provided by an embodiment of the present application. Please refer to Figure 3 The power domain system 102 includes a power domain general controller 1021, a first power domain sub-controller 1022, a second power domain sub-controller 1023 and a third power domain sub-controller 1024 in communication connection with the power domain general controller 1021.

[0026] As an example, the first power domain sub-controller 1022 can be a motor controller (MCU), the second power domain sub-controller 1023 can be a battery management system controller (BMS), and the third power domain sub-controller 1024 can be an engine controller (ECU). The first power domain power consumption data can be the real-time efficiency of the motor; the second power domain power consumption data can be the SOC value of the battery; and the third power domain power consumption data can be the engine load rate.

[0027] Based on the power domain power consumption dataset, the power domain power consumption coordination management strategy for the power domain system is determined, including: determine a first intra-power domain coordination response rule for the second power domain sub-controller and the third power domain sub-controller based on the first power domain power consumption data; determine a second intra-power domain coordination response rule for the first power domain sub-controller and the third power domain sub-controller based on the second power domain power consumption data; determine a third intra-power domain coordination response rule for the first power domain sub-controller and the second power domain sub-controller based on the third power domain power consumption data.

[0028] In an example, the first intra-power domain coordination response rule for the second power domain sub-controller and the third power domain sub-controller is determined based on the first power domain power consumption data. Specifically, if the first power domain power consumption data (such as the real-time efficiency of the motor) is less than a first preset threshold (such as 85%), the first intra-power domain coordination response rule is that the second power domain sub-controller 1023 (such as the BMS) responds to reduce the discharge current by 10% to preferentially guarantee the voltage stability of the first power domain sub-controller 1022 (such as the MCU); at the same time, if the vehicle is in hybrid mode, the third power domain sub-controller 1024 (such as the ECU) responds to start the engine in advance and switch to parallel driving to share the load of the motor.

[0029] Next, the vehicle controller 101 issues the above-mentioned first intra-power domain coordination response rule to the power domain master controller 1021, which then distributes it to the second power domain sub-controller 1023 (such as the BMS) and the third power domain sub-controller 1024 (such as the ECU), and the BMS and the ECU make corresponding responses respectively to achieve coordinated control of power consumption within the power domain, thereby reducing the energy consumption of the whole vehicle and being beneficial to prolonging the vehicle's endurance and the service life of the battery.

[0030] In another example, the second intra-power domain coordination response rule for the first power domain sub-controller and the third power domain sub-controller is determined based on the second power domain power consumption data. Specifically, if the second power domain power consumption data (the battery SOC value) is less than a second preset threshold (such as 20%), the second intra-power domain coordination response rule is that the first power domain sub-controller 1022 (such as the MCU) responds to forcibly limit the motor torque to the rated value (such as 60%); at the same time, if the vehicle is a range extended vehicle, the third power domain sub-controller 1024 (such as the ECU) responds to forcibly start the range extender and lock to the highest efficiency speed (such as 2000 rpm).

[0031] Next, the vehicle controller 101 issues the above-mentioned second power domain coordination response rule to the power domain master controller 1021, which is then distributed to the first power domain sub-controller 1022 (such as MCU) and the third power domain sub-controller 1024 (such as ECU) by the power domain master controller 1021, and the corresponding responses are made by the MCU and ECU respectively to achieve the coordinated control of the power consumption in the power domain, thereby reducing the vehicle energy consumption and prolonging the vehicle endurance and battery service life.

[0032] In yet another example, based on the third power domain power consumption data, a third power domain coordination response rule for the first power domain sub-controller and the second power domain sub-controller is determined. Specifically, if the third power domain power consumption data (such as engine load rate) is greater than a third preset threshold (such as 90%), the second power domain sub-controller 1023 (such as BMS) responds to instantaneously increase the voltage to 105% of the rated value (such as from 400V to 420V) to reduce the current to reduce line loss; at the same time, the first power domain sub-controller 1022 (such as MCU) responds after a delay of 5 seconds to avoid simultaneous peak output of the engine and the motor.

[0033] Next, the vehicle controller 101 issues the above-mentioned third power domain coordination response rule to the power domain master controller 1021, which is then distributed to the first power domain sub-controller 1022 (such as MCU) and the second power domain sub-controller 1023 (such as BMS) by the power domain master controller 1021, and the corresponding responses are made by the MCU and BMS respectively to achieve the coordinated control of the power consumption in the power domain, thereby reducing the vehicle energy consumption and prolonging the vehicle endurance and battery service life.

[0034] Figure 4 is a system structure schematic diagram of a chassis domain system provided by an embodiment of the present application. Please refer to Figure 4 The chassis domain system 103 includes a chassis domain master controller 1031, a first chassis domain sub-controller 1032, a second chassis domain sub-controller 1033, and a third chassis domain sub-controller 1034 which are in communication connection with the chassis domain master controller 1031.

[0035] As an example, the first chassis domain sub-controller 1032 can be specifically an electric power steering controller (EPS), the second chassis domain sub-controller 1033 can be specifically a chassis domain controller (VDC), and the third chassis domain sub-controller 1034 can be specifically an air suspension controller (ECAS). The first chassis domain power consumption data can be specifically the steering wheel speed, the second chassis domain power consumption data can be specifically the vehicle speed, and the third chassis domain power consumption data can be specifically the suspension height deviation value.

[0036] In some embodiments, based on the chassis domain power consumption data set, a chassis domain power consumption coordination management strategy for the chassis domain system is determined, which includes: determine a first intra-chassis domain coordination response rule for the second chassis domain sub-controller and the third chassis domain sub-controller based on the first chassis domain power consumption data; determine a second intra-chassis domain coordination response rule for the first chassis domain sub-controller and the third chassis domain sub-controller based on the second chassis domain power consumption data; determine a third intra-chassis domain coordination response rule for the first chassis domain sub-controller and the second chassis domain sub-controller based on the third chassis domain power consumption data.

[0037] In an example, the first intra-chassis domain coordination response rule for the second chassis domain sub-controller and the third chassis domain sub-controller is determined based on the first chassis domain power consumption data. Specifically, if the first chassis domain power consumption data (such as steering wheel speed) is less than a fourth preset threshold (such as 10° / s), the first intra-chassis domain coordination response rule is that the second chassis domain sub-controller 1033 (such as VDC) responds to reduce the yaw damping control frequency (such as from 20 Hz to 5 Hz) and reduce the number of electromagnetic valve actions by about 30%; if the vehicle speed = 0 at this time, the third chassis domain sub-controller 1034 (such as ECAS) responds to immediately turn off the air pump motor, and the height adjustment request is delayed for 30 s to be executed.

[0038] Next, the vehicle controller 101 issues the above-mentioned first intra-chassis domain coordination response rule to the chassis domain total controller 1031, which is then distributed to the second chassis domain sub-controller 1033 (such as VDC) and the third chassis domain sub-controller 1034 (such as ECAS) by the chassis domain total controller 1031. The VDC and the ECAS make corresponding responses respectively to achieve the coordinated regulation of power consumption within the chassis domain, thereby reducing the energy consumption of the whole vehicle and being beneficial to prolong the endurance and battery life of the whole vehicle.

[0039] In another example, the second intra-chassis domain coordination response rule for the first chassis domain sub-controller and the third chassis domain sub-controller is determined based on the second chassis domain power consumption data. Specifically, if the second chassis domain power consumption data (such as vehicle speed) is greater than a fifth preset threshold (such as 120 km / h), the second intra-chassis domain coordination response rule is that the first chassis domain sub-controller 1032 (such as EPS) responds to reduce the upper limit of the assist current (for example, the upper limit of the assist current is reduced from 90 A to 70 A), which can make the high-speed energy consumption decrease by about 15%. At the same time, the third chassis domain sub-controller 1034 (such as ECAS) responds to disable the "comfort height adjustment" function and only keep the "load balance" function, and reduce the air pump duty cycle by half.

[0040] Next, the vehicle controller 101 issues the above-mentioned second chassis domain coordination response rule to the chassis domain general controller 1031, which then distributes the rule to the first chassis domain sub-controller 1032 (e.g., EPS) and the third chassis domain sub-controller 1034 (e.g., ECAS), which make corresponding responses to achieve coordinated control of power consumption in the chassis domain, thereby reducing the energy consumption of the vehicle and prolonging the vehicle's endurance and battery life.

[0041] In yet another example, based on the third chassis domain power consumption data, a third chassis domain coordination response rule for the first chassis domain sub-controller and the second chassis domain sub-controller is determined. Specifically, if the third chassis domain power consumption data (e.g., suspension height deviation value |ΔH|) is less than a sixth preset threshold (e.g., 5 mm), the third chassis domain coordination response rule is: the first chassis domain sub-controller 1032 responds to reduce the assist output and reduce the motor current, for example, the assist output is reduced by 2%, and the motor current is reduced by 0.8 A; at the same time, the second chassis domain sub-controller 1033 (e.g., VDC) responds to exit continuous damping adjustment, maintain the current damping value, and the solenoid valve is powered off to save energy.

[0042] Next, the vehicle controller 101 issues the above-mentioned third chassis domain coordination response rule to the chassis domain general controller 1031, which then distributes the rule to the first chassis domain sub-controller 1032 (e.g., EPS) and the second chassis domain sub-controller 1033 (e.g., VDC), which make corresponding responses to achieve coordinated control of power consumption in the chassis domain, thereby reducing the energy consumption of the vehicle and prolonging the vehicle's endurance and battery life.

[0043] Figure 5 is a system structure schematic diagram of a vehicle body domain system provided by an embodiment of the present application. Please refer to Figure 5 The vehicle body domain system 104 includes a vehicle body domain general controller 1041, a first vehicle body domain sub-controller 1042, a second vehicle body domain sub-controller 1043, and a third vehicle body domain sub-controller 1044 which are in communication connection with the vehicle body domain general controller 1041.

[0044] As an example, the first vehicle body domain sub-controller 1042, the second vehicle body domain sub-controller 1043, and the third vehicle body domain sub-controller 1044 can be a body controller (BCM), an air conditioning controller (HVAC), and a gateway controller (GW) respectively. The first vehicle body domain power consumption data can be specifically a vehicle door switch state; the second vehicle body domain power consumption data can be specifically an inside-outside temperature difference; and the third vehicle body domain power consumption data can be specifically a CAN bus load rate.

[0045] Based on the vehicle body domain power consumption data set, a vehicle body domain power consumption coordination management strategy for the vehicle body domain system is determined, including: determine a first body domain intra-coordination response rule for the second body domain sub-controller and the third body domain sub-controller based on the first body domain power consumption data and the second chassis domain power consumption data; determine a second body domain intra-coordination response rule for the first body domain sub-controller and the third body domain sub-controller based on the second body domain power consumption data; determine a third body domain intra-coordination response rule for the first body domain sub-controller and the second body domain sub-controller based on the third body domain power consumption data.

[0046] In an example, the first body domain intra-coordination response rule for the second body domain sub-controller and the third body domain sub-controller is determined based on the first body domain power consumption data and the second chassis domain power consumption data. Specifically, if the first body domain power consumption data (such as the door opening and closing state) is that any door is opened, and the second chassis domain power consumption data (such as the vehicle speed) is greater than a seventh preset threshold (such as 5 km / h), the first body domain intra-coordination response rule is that the second body domain sub-controller 1043 (such as HVAC) responds to reduce the compressor speed by 30%, and the negative ion / fragrance pump is turned off, so that the power consumption is reduced by about 200 W. At the same time, the third body domain sub-controller 1044 (such as GW) responds to pause non-diagnostic messages (such as ambient light, seat position broadcast, etc.), so that the CAN bus load is reduced by about 5%.

[0047] Next, the vehicle controller 101 issues the above-mentioned first body domain intra-coordination response rule to the body domain general controller 1041, which is then distributed to the second body domain sub-controller 1043 (such as HVAC) and the third body domain sub-controller 1044 (such as GW) by the body domain general controller 1041. The HVAC and GW make corresponding responses respectively to achieve the coordinated control of the power consumption in the body domain, thereby reducing the overall vehicle energy consumption and being beneficial to prolong the vehicle endurance and battery service life.

[0048] In another example, the second body domain intra-coordination response rule for the first body domain sub-controller and the third body domain sub-controller is determined based on the second body domain power consumption data. Specifically, if the second body domain power consumption data (such as the temperature difference inside and outside the vehicle |ΔT|) is less than an eighth preset threshold (such as 3℃), the second body domain intra-coordination response rule is that the first body domain sub-controller 1042 (such as BCM) responds to turn off the seat ventilation / heating and only keep the basic lighting, so that the static current is reduced by 1.2 A. At the same time, the third body domain sub-controller 1044 (such as GW) responds to extend the HVAC state frame period, for example, from 100 ms to 1 s, so that the CAN bandwidth occupation is reduced by about 0.8%.

[0049] Next, the vehicle controller 101 issues the above-mentioned second in-vehicle body domain coordinated response rule to the vehicle body domain general controller 1041, which then distributes it to the first vehicle body domain sub-controller 1042 (such as the BCM) and the third vehicle body domain sub-controller 1044 (such as the GW). The BCM and the GW make corresponding responses respectively to achieve coordinated control of power consumption within the vehicle body domain, thereby reducing the overall vehicle energy consumption and being conducive to prolonging the vehicle's range and battery life.

[0050] In yet another example, based on the third vehicle body domain power consumption data, a third in-vehicle body domain coordinated response rule for the first vehicle body domain sub-controller and the second vehicle body domain sub-controller is determined. Specifically, if the third vehicle body domain power consumption data (such as the CAN bus load rate) is greater than a ninth preset threshold (such as 80%), the third in-vehicle body domain coordinated response rule is that the first vehicle body domain sub-controller 1042 (such as the BCM) delays responding to the remote key find vehicle instruction and reduces the low-frequency flash light duty cycle, for example, delays responding to the remote key find vehicle instruction by 200 ms and reduces the low-frequency flash light duty cycle by half. At the same time, the second vehicle body domain sub-controller 1043 (such as the HVAC) sets the target temperature allowable deviation to ±2°C, reduces the compressor start-stop frequency, and reduces the peak current (such as reducing the peak current by 10%).

[0051] Next, the vehicle controller 101 issues the above-mentioned third in-vehicle body domain coordinated response rule to the vehicle body domain general controller 1041, which then distributes it to the first vehicle body domain sub-controller 1042 (such as the BCM) and the second vehicle body domain sub-controller 1043 (such as the HVAC). The BCM and the HVAC make corresponding responses respectively to achieve coordinated control of power consumption within the vehicle body domain, thereby reducing the overall vehicle energy consumption and being conducive to prolonging the vehicle's range and battery life.

[0052] In some embodiments, the inter-domain power consumption coordination management strategy includes a first inter-domain power consumption coordination management strategy, a second inter-domain power consumption coordination management strategy, a third inter-domain power consumption coordination management strategy, and a fourth inter-domain power consumption coordination management strategy. Based on the power domain power consumption data set, the chassis domain power consumption data set, and the vehicle body domain power consumption data set, the inter-domain power consumption coordination management strategy is determined, including: determining the first inter-domain power consumption coordination management strategy based on the power domain power consumption data set and the vehicle body domain power consumption data set; determining the second inter-domain power consumption coordination management strategy based on the power domain power consumption data set and the chassis domain power consumption data set; determining the third inter-domain power consumption coordination management strategy based on the chassis domain power consumption data set and the vehicle body domain power consumption data set; determining the fourth inter-domain power consumption coordination management strategy based on the vehicle body domain power consumption data set.

[0053] In some embodiments, the first inter-domain power consumption coordination management strategy includes a first inter-domain power consumption response rule, a second inter-domain power consumption response rule, and a third inter-domain power consumption response rule; determining the first inter-domain power consumption coordination management strategy based on the power domain power consumption data set and the vehicle body domain power consumption data set includes: If the second power domain power consumption data and the first vehicle body domain power consumption data meet the preset limit energy-saving mode triggering condition, a first inter-domain power consumption response rule for the power domain system, a second inter-domain power consumption response rule for the chassis domain system, and a third inter-domain power consumption response rule for the vehicle body domain system are generated.

[0054] The preset limit energy-saving mode triggering condition can be that the battery SOC value is less than 15% (severe low power) and the vehicle is in a driving state.

[0055] As an example, assuming that the vehicle controller 101 generates a first inter-domain power consumption response rule for the power domain system, a second inter-domain power consumption response rule for the chassis domain system, and a third inter-domain power consumption response rule for the vehicle body domain system when the second power domain power consumption data (such as the battery SOC value) reported by the second power domain sub-controller 1023 (such as the BMS) in the power domain system 102 is less than 15% (severe low power) and it is determined based on the first vehicle body domain power consumption data (such as the door switch state) reported by the first vehicle body domain sub-controller 1042 (such as the BCM) in the vehicle body domain system 104 that the vehicle is in a driving state, i.e., the limit energy-saving mode triggering condition is met. Wherein, (1) the first inter-domain power consumption response rule includes: the response measures of the power domain system include: for the MCU, limiting the maximum output power to 50%, limiting the maximum speed to 80 km / h; for the BMS, requesting to relax the battery discharge cutoff voltage and allowing the use of the last reserve energy; for the ECU (hybrid vehicle), forcing the engine to work in the highest efficiency fixed power generation interval. (2) The second inter-domain power consumption response rule includes: the response measures of the chassis domain system include: for the EPS, reducing the assist level (the steering becomes heavy), and reminding the driver; for the ECAS, locking the suspension height and prohibiting any adjustment to save the air compressor power consumption; for the VDC, turning off the TCS traction control and other non-core functions (keeping the anti-lock braking system (ABS) function). (3) The third inter-domain power consumption response rule includes: the response measures of the vehicle body domain system include: for the BCM, automatically turning off the atmosphere lamp, entertainment large screen, seat heating and other non-essential electrical appliances; for the HVAC, forcibly turning off the air conditioner compressor and switching to the outside circulation ventilation mode.

[0056] Next, the vehicle controller 101 issues the first inter-domain power consumption response rule described above to the power domain general controller 1021, and the power domain general controller 1021 issues corresponding response instructions to the first power domain sub-controller 1022, the second power domain sub-controller 1023 and the third power domain sub-controller 1024 according to the first inter-domain power consumption response rule, so as to complete the power consumption regulation in the power domain. The vehicle controller 101 issues the second inter-domain power consumption response rule described above to the chassis domain general controller 1031, and the chassis domain general controller 1031 issues corresponding response instructions to the first chassis domain sub-controller 1032, the second chassis domain sub-controller 1033 and the third chassis domain sub-controller 1034 according to the second inter-domain power consumption response rule, so as to complete the power consumption regulation in the chassis domain. The vehicle controller 101 issues the third inter-domain power consumption response rule described above to the vehicle body domain general controller 1041, and the vehicle body domain general controller 1041 issues corresponding response instructions to the first vehicle body domain sub-controller 1042 and the second vehicle body domain sub-controller 1043 according to the third inter-domain power consumption response rule, so as to complete the power consumption regulation in the vehicle body domain.

[0057] When the vehicle controller 101 detects that the vehicle is in a non-driving state (such as the vehicle being turned off) or the battery SOC value is greater than 20%, the vehicle exits the above-mentioned extreme energy-saving mode.

[0058] The above-mentioned scheme can realize inter-domain power consumption collaborative regulation of the power domain system, the chassis domain system and the vehicle body domain system, thereby reducing the energy consumption of the whole vehicle and being beneficial to prolonging the endurance of the whole vehicle and the service life of the battery.

[0059] In some embodiments, the second inter-domain power consumption coordination management strategy includes a fourth inter-domain power consumption response rule, a fifth inter-domain power consumption response rule and a sixth inter-domain power consumption response rule; the second inter-domain power consumption coordination management strategy is determined based on the power domain power consumption data set and the chassis domain power consumption data set, including: If the first power domain power consumption data and the second chassis domain power consumption data meet the preset high-efficiency cruise mode triggering condition, the fourth inter-domain power consumption response rule for the power domain system, the fifth inter-domain power consumption response rule for the chassis domain system and the sixth inter-domain power consumption response rule for the vehicle body domain system are generated.

[0060] The preset high-efficiency cruise mode triggering condition can be that the motor request torque value is stable within ±10% and the torque absolute value is low (in a smooth driving state), and the vehicle speed is greater than 70km / h and the lateral acceleration is less than 0.2g (in a high-speed straight driving state).

[0061] As an example, assuming that the vehicle controller 101 determines that the vehicle meets the above-mentioned preset high-efficiency cruise mode triggering condition according to the first power domain power consumption data reported by the first power domain sub-controller 1022 (such as MCU) in the power domain system 102 and the second chassis domain power consumption data reported by the second chassis domain sub-controller 1033 in the chassis domain system 103, then generate the fourth inter-domain power consumption response rule for the power domain system, the fifth inter-domain power consumption response rule for the chassis domain system, and the sixth inter-domain power consumption response rule for the vehicle body domain system. Among them, (4) the fourth inter-domain power consumption response rule includes: the response measures of the power domain system include: optimizing the torque distribution between MCU, BMS and ECU, and ensuring that the motor or engine works in the highest efficiency interval. (5) The fifth inter-domain power consumption response rule includes: the response measures of the chassis domain system include: for ECAS, send the "lower the body" instruction to reduce the wind resistance and achieve maximum energy saving; for EPS, switch to "high-speed" assist mode, reduce the assist current and reduce power consumption; for VDC, enter the predictive economy mode to reduce unnecessary active intervention. (6) The sixth inter-domain power consumption response rule includes: the response measures of the vehicle body domain system include: for HVAC, preferably use automatic circulation to reduce the compressor frequent start-stop.

[0062] Next, the vehicle controller 101 respectively issues the above-mentioned fourth inter-domain power consumption response rule, fifth inter-domain power consumption response rule, and sixth inter-domain power consumption response rule to the power domain master controller 1021, chassis domain master controller 1031 and vehicle body domain master controller 1041. The power domain master controller 1021 determines the torque distribution coefficients of MCU, BMS and ECU according to the fourth inter-domain power consumption response rule to optimize the torque of MCU, BMS and ECU, and complete the power consumption collaborative control within the power domain. The chassis domain master controller 1031 issues corresponding response instructions to ECAS, EPS and VDC according to the fifth inter-domain power consumption response rule to complete the power consumption collaborative control within the chassis domain. The vehicle body domain master controller 1041 issues corresponding response instructions to HVAC according to the sixth inter-domain power consumption response rule to complete the power consumption collaborative control within the vehicle body domain.

[0063] When the vehicle controller 101 detects that the vehicle speed is less than 60km / h or the motor request torque value suddenly increases (vehicle rapid acceleration driving) or the steering wheel angle increases (vehicle steering driving), the above-mentioned high-efficiency cruise mode is exited.

[0064] The above-mentioned scheme can realize the inter-domain power consumption collaborative control of the power domain system, chassis domain system and vehicle body domain system, thereby reducing the energy consumption of the whole vehicle and being beneficial to prolong the vehicle endurance and battery service life.

[0065] In some embodiments, the third inter-domain power consumption coordination management strategy includes a seventh inter-domain power consumption response rule and an eighth inter-domain power consumption response rule; based on the chassis domain power consumption data set and the vehicle body domain power consumption data set, the third inter-domain power consumption coordination management strategy is determined, including: If the first chassis domain power consumption data and the first vehicle body domain power consumption data meet the preset congestion standby mode trigger condition, the seventh inter-domain power consumption response rule for the power domain system, the eighth inter-domain power consumption response rule for the chassis domain system, and the ninth inter-domain power consumption response rule for the vehicle body domain system are generated.

[0066] The preset congestion standby mode trigger condition can be that the current driving state of the vehicle is "vehicle start state" (Ready-On), and the current vehicle speed is 0 km / h and the duration is greater than 60 seconds (long time parking and waiting).

[0067] As an example, assuming that the vehicle controller 101 determines that the vehicle meets the above-mentioned preset congestion standby mode trigger condition according to the first vehicle body domain power consumption data reported by the vehicle body domain master controller 1041 and the first chassis domain power consumption data reported by the chassis domain master controller 1031, then the seventh inter-domain power consumption response rule for the power domain system and the eighth inter-domain power consumption response rule for the vehicle body domain system are generated. Among them, (7) the seventh inter-domain power consumption response rule includes: the response measures of the power domain system include: for ECU (fuel / mixed vehicle), automatic start-stop is performed, and the engine is turned off; for MCU / BMS, enter low-power standby, and be ready to respond to torque request at any time. (8) The eighth inter-domain power consumption response rule includes: the response measures of the vehicle body domain system include: for HVAC, if the temperature difference between the inside and outside of the vehicle is not large, the fan gear can be reduced or switched to internal circulation to maintain basic comfort. For BCM, the backlight of the instrument panel and the central control screen can be dimmed or turned off.

[0068] Next, the vehicle controller 101 issues the above-mentioned seventh inter-domain power consumption response rule to the power domain master controller 1021, and then the power domain master controller 1021 issues corresponding response instructions to the first power domain sub-controller 1022, the second power domain sub-controller 1023 and the third power domain sub-controller 1024 according to the seventh inter-domain power consumption response rule, to complete the power consumption regulation in the power domain. The vehicle controller 101 issues the above-mentioned eighth inter-domain power consumption response rule to the vehicle body domain master controller 1041, and then the vehicle body domain master controller 1041 issues corresponding response instructions to HVAC and BCM according to the eighth inter-domain power consumption response rule, to complete the power consumption regulation in the vehicle body domain.

[0069] When the vehicle controller 101 detects that the driver steps on the accelerator or brake pedal, the above-mentioned congestion standby mode is exited.

[0070] The above scheme can realize inter-domain power consumption coordination and control of the power domain system, the chassis domain system and the vehicle body domain system, thereby reducing the energy consumption of the whole vehicle and prolonging the endurance of the whole vehicle and the service life of the battery.

[0071] In some embodiments, the fourth inter-domain power consumption coordination management strategy includes a ninth inter-domain power consumption response rule, a tenth inter-domain power consumption response rule and an eleventh inter-domain power consumption response rule; the fourth inter-domain power consumption coordination management strategy is determined based on the vehicle body domain power consumption data set, including: If the first vehicle body domain power consumption data and the third vehicle body domain power consumption data meet the preset deep sleep mode trigger condition, the ninth inter-domain power consumption response rule for the power domain system, the tenth inter-domain power consumption response rule for the chassis domain system and the eleventh inter-domain power consumption response rule for the vehicle body domain system are generated.

[0072] The preset deep sleep mode trigger condition can be that the current vehicle state is "locked state" ("Locked"), and the CAN bus load rate is less than 3% and the duration is greater than 5 minutes (network communication basically stops).

[0073] As an example, assuming that the whole vehicle controller 101 determines that the vehicle meets the above preset deep sleep mode trigger condition according to the first vehicle body domain power consumption data and the third vehicle body domain power consumption data reported by the vehicle body domain total controller 1041, the ninth inter-domain power consumption response rule for the power domain system, the tenth inter-domain power consumption response rule for the chassis domain system and the eleventh inter-domain power consumption response rule for the vehicle body domain system are generated. Among them, (9) the ninth inter-domain power consumption response rule includes that the response measure of the power domain system includes that the BMS, MCU and ECU enter the lowest power consumption state, and only the key state monitoring is reserved. (10) The tenth inter-domain power consumption response rule includes that the response measure of the chassis domain system includes that the EPS, VDC and ECAS enter the sleep state, and all sensor power supplies are turned off. (11) The eleventh inter-domain power consumption response rule includes that the response measure of the vehicle body domain system includes that for the GW, most of the network channels are turned off, and only a single channel for listening to the remote key is reserved; for the BCM / HVAC, enter deep sleep, and only the ability to wake up through a hard-wired signal (such as opening the door) is reserved.

[0074] Next, the vehicle controller 101 issues the ninth inter-domain power consumption response rule described above to the power domain master controller 1021, and the power domain master controller 1021 issues corresponding response instructions to the BMS, MCU and ECU according to the ninth inter-domain power consumption response rule, so as to complete the power consumption collaborative control in the power domain. The vehicle controller 101 issues the tenth inter-domain power consumption response rule described above to the chassis domain master controller 1031, and the chassis domain master controller 1031 issues corresponding response instructions to the EPS, VDC and ECAS according to the tenth inter-domain power consumption response rule, so as to complete the power consumption control in the chassis domain. The vehicle controller 101 issues the eleventh inter-domain power consumption response rule described above to the vehicle body domain master controller 1041, and the vehicle body domain master controller 1041 issues corresponding response instructions to the GW, BCM and HVAC according to the eleventh inter-domain power consumption response rule, so as to complete the power consumption control in the vehicle body domain.

[0075] When the vehicle controller 101 receives the remote key unlocking signal reported by the BCM or the message that the network wake-up frame is received reported by the GW, the deep sleep mode described above is exited.

[0076] The above scheme can realize the inter-domain power consumption collaborative control of the power domain system, the chassis domain system and the vehicle body domain system, thereby reducing the energy consumption of the whole vehicle and being beneficial to prolong the cruising range and the service life of the battery of the whole vehicle.
