[0071] Other advantages and effects of the present application can be easily understood by those skilled in the art from the above description of the preferred embodiments of the present application. The present application can also be implemented or applied in other different specific embodiments, and the details in the present specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, and are not intended to limit the protection scope of the present application.

[0072] It is to be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concepts of the present application, and only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shapes, number and ratio of the components in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0073] In the following description, a large number of details are discussed in order to provide a more thorough explanation of the embodiments of the present application, however, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details, and in other embodiments, the well-known structures and devices are shown in the form of block diagrams rather than in the form of details, in order to avoid making the embodiments of the present application difficult to understand.

[0074] In order to make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0075] With global warming, energy saving and emission reduction has become an important development strategy of the country. As an important support for economic development and a tool commonly used in people's daily life, the huge amount of cars provides a huge space for energy saving and emission reduction. Energy management technology is the core technology for vehicle energy saving and emission reduction, and its development is increasingly valued by automobile manufacturers. In the current energy management design, the host manufacturers and engineers pay more attention to the energy management of the power system, thermal management system and mechanical system, and do not pay enough attention to the energy consumption management of the low-voltage system. The low-voltage energy consumption management scheme in the related art only makes limited energy consumption management of a single system. Based on the above problems, the present application aims to design a new vehicle-level low-voltage energy consumption management system scheme to solve the energy consumption management of vehicles in various scenes. By separating the energy consumption of the electrical appliances from the energy consumption request of the energy control system, the purpose of flexible control and energy consumption reduction according to different needs is achieved.

[0076] Please refer to Figure 1 , which is a flowchart of a vehicle energy consumption control method provided in an embodiment of the present application;

[0077] As Figure 1 shown, the vehicle energy consumption control method includes the following steps:

[0078] S101, obtaining environment information and vehicle state information of a target vehicle;

[0079] S102, determining a scene mode corresponding to the target vehicle based on the vehicle state information and the environment information;

[0080] Since the scene is mainly identified by judging the vehicle body, control and other information. The main states set in this embodiment are parking, driving and other three scenes. The parking state includes vehicle long-time dormant parking (business trip mode), vehicle short-time dormant parking (quick start mode), vehicle charging (charging mode), intelligent power compensation (charging mode), sentinel function (sentinel mode), camping demand (camping mode), vehicle OTA writing (OTA mode) and other small scenes. The driving state includes super endurance (super power-saving driving mode), economic driving mode, comfortable driving mode, sports driving mode and other small scenes. Other states include network exception, low battery and other small scenes.

[0081] The main scene recognition conditions are as follows:

[0082] Basic information: vehicle low-voltage power supply gear (ON / OFF), driving system state (not ready / ready), vehicle speed (greater than / less than 3km / h), vehicle network dormant state, brake state (EPB pull up / release), gear information (P / D / N / R), DCDC state (on / off) and the like.

[0083] Trigger information: driving mode, OTA (Over-The-Air technology, over-the-air technology) state, vehicle charging connection state, special system working mode state (intelligent power compensation, sentinel, camping network exception and the like) and the like.

[0084] The above conditions cannot absolutely exclude the classification of vehicle use scene, and scene crossing or covering may occur when identifying the vehicle state. At this time, multiple energy consumption levels may appear for the energy consumption level of the electrical appliance. When such a state occurs, the maximum power consumption level in these scenes is requested.

[0085] S103, triggering the preset energy consumption level request of the target vehicle according to the scene mode;

[0086] In this embodiment, the intelligent power distribution management system obtains vehicle conditions, environmental conditions and electrical system states, and then makes corresponding responses. The main function of the intelligent power distribution management system is to distribute power to each execution system, that is, to distribute power to the whole vehicle electrical appliance.

[0087] S104, in response to the energy consumption level request, determining the energy consumption level of each electrical device of the target vehicle according to the mapping relationship between the scene mode, the whole vehicle function, the electrical device and the energy consumption level, wherein the scene mode corresponds to at least one whole vehicle function, each whole vehicle function corresponds to at least one electrical device, and each electrical device corresponds to at least multiple energy consumption levels;

[0088] The intelligent power distribution management system identifies the energy consumption level request sent by the energy consumption level management system, splits and converts the energy consumption level request, and sends the energy consumption level request to each power consumption execution end. Meanwhile, the intelligent power distribution management system receives the energy consumption level feedback information of the power consumption execution end to achieve the purpose of closed-loop control.

[0089] S105, performing power consumption according to the energy consumption level corresponding to each power consumption device to realize vehicle energy consumption control.

[0090] When the power-off condition is met, the power-off control is performed on the power consumption execution end to achieve the purpose of energy saving.

[0091] S106, each execution system performs power consumption based on the energy consumption level.

[0092] Each execution system includes a subsystem controller, an actuator, a sensor, and the like. Each execution system mainly functions to identify the scene mode in which the target vehicle is located, receive and respond to the energy consumption level request of the energy consumption level management system, and feedback the execution condition and state.

[0093] In the embodiment, first, the whole vehicle function demand analysis is performed; the vehicle power consumption system support analysis is performed; the vehicle controller-energy consumption level list design is performed; the energy consumption level system design and research and development of the power consumption system are performed; the vehicle scene classification, each scene definition, and the entering condition design are performed; the function demand and power consumption device demand in the scene are sorted out; the energy consumption level definition of each power consumption system in the scene and the energy consumption level coordination after the scene intersection are performed; the energy consumption level control in the multi-scene intersection is performed; and the system scheme test and verification in the scene are performed. Compared with the prior art, the technical scheme provided in the application can improve the use efficiency of the whole vehicle electric energy by monitoring the actual state of the vehicle, judging the scene in which the current vehicle is located based on the set rules, sending the corresponding energy consumption level of each power consumption device, and dynamically adjusting the energy consumption of the whole vehicle power consumption system.

[0094] In the above manner, after the scene mode of the vehicle is acquired, the energy consumption level of each power consumption device of the target vehicle is determined according to the mapping relationship among the scene mode, the whole vehicle function, the power consumption device, and the energy consumption level. By adjusting each power consumption device in the vehicle, the flexibility of energy consumption control can be obviously improved compared with the prior art. Meanwhile, the energy consumption of each power consumption device can be finely managed, the energy consumption level of each power consumption device is further determined, the flexibility and accuracy of energy consumption control are greatly improved compared with the prior art, and the purpose of accurately saving energy consumption is achieved.

[0095] Please refer to Figure 2 is a flowchart of an execution state feedback method provided in an embodiment of the application;

[0096] As Figure 2As shown, the execution state feedback method comprises the following steps:

[0097] S201, feedback the execution state of each power consumption equipment corresponding to the energy consumption level to the intelligent power distribution management system;

[0098] The scene recognition and energy consumption level management system includes a trigger layer and a coordination management layer, and the distribution and execution system includes a distribution layer and an execution layer. Each execution system will feedback the execution state to the intelligent power distribution management unit of the distribution layer after executing power consumption, that is, the intelligent power distribution management system.

[0099] S202, and forward the execution state of power consumption to the scene recognition and energy consumption level management system.

[0100] The intelligent power distribution management unit of the intelligent power distribution management system will forward the feedback execution state to the scene recognition and energy consumption level management system. The execution layer is a plurality of power consumers, and the power consumers (i.e., power consumption equipment) will feedback the execution state to the distribution layer and the intelligent power distribution management unit of the intelligent power distribution management system through the CAN mode.

[0101] In the above manner, by distributing the energy consumption levels of a plurality of power consumption equipment, accurate and flexible control of energy consumption is realized to achieve the purpose of energy consumption control.

[0102] Please refer to Figure 3 , which is a flowchart of the method for the intelligent power distribution unit to execute power-off of each execution system in an embodiment of the present application;

[0103] As shown, the power-off execution method comprises the following steps: Figure 3

[0104] S301, the scene recognition and energy consumption level management system sends a power-off request to the intelligent power distribution management system;

[0105] S302, the intelligent power distribution management system includes an intelligent power distribution unit, and the intelligent power distribution unit as a power-off executor executes power-off operation on each execution system based on the power-off request.

[0106] After the intelligent power distribution unit as a power-off executor executes power-off operation on each execution system based on the power-off request, the intelligent power distribution unit feedbacks the execution result of the power-off to the scene and energy consumption level management system.

[0107] When the energy consumption level requirement for the power consumer is power-off, in addition to completing the above-mentioned interaction logic, the scene recognition and energy consumption level management system also needs to separately request the intelligent power distribution management unit to power off, at which time the intelligent power distribution unit as an executor executes power-off operation and feedbacks the execution result to the scene recognition and energy consumption level management system.

[0108] ​Through the above manner, the power-off operation is performed on certain electric equipment, and unnecessary energy consumption is greatly saved.

[0109] Please refer to Figure 4 , a flowchart of the method for calculating energy consumption provided by an embodiment of the present application is shown in the figure.

[0110] As shown in the figure, the method for calculating energy consumption comprises the following steps: Figure 4 S401, real-time monitoring of input voltage of each power chip and real-time current required for operation of each power chip;

[0111] S402, determining energy consumption of electric equipment connected to each power chip according to the correlation between the input voltage, the real-time current and the operation time, calculating total energy consumption of each electric equipment in a preset time, and outputting and displaying the total energy consumption; wherein, the operation time is the length of time for monitoring the real-time current and the input voltage.

[0112] The intelligent power distribution management system is mainly responsible for power distribution for vehicle electric appliances. The system can monitor the input voltage in front of the power chip through the MCU in the system in real time. At the same time, each power chip has the ability to monitor its own current (10ms cycle for a single interface). Therefore, the intelligent power distribution management system can calculate the energy consumption of electric appliances at the back end of each power chip according to the relationship between the current, voltage and time of the power chip, and aggregate the total energy consumption in the same time period to achieve the purpose of energy consumption display and energy consumption monitoring.

[0113] Please refer to Figure 5 , a flowchart of the method for determining whether each execution system performs power consumption provided by an embodiment of the present application is shown in the figure.

[0114] As shown in the figure, the method for determining whether each execution system performs power consumption comprises the following steps: Figure 5

[0115] S501, determining whether the target vehicle meets the execution condition based on the energy consumption level;

[0116] S502, when the execution condition is met, performing power consumption by using the execution system, and feeding back the power consumption state;

[0117] S503, when the execution condition is not met, the execution system does not perform power consumption, and analyzes the reason why the target vehicle does not meet the execution condition for reporting.

[0118] Through the above manner, it can be accurately determined whether the current vehicle can perform the corresponding energy consumption level, ensuring that the vehicle has sufficient energy consumption to realize the corresponding function, avoiding affecting the realization of necessary functions of the vehicle, such as normal driving function; at the same time, it can also avoid wasting energy consumption of the vehicle.

[0119] Please refer to​Figure 6 is a flowchart of a method for determining whether to perform power consumption when an execution system is a steering system according to an embodiment of the present application;

[0120] As shown in Figure 6 , the method for determining whether to perform power consumption when an execution system is a steering system comprises the following steps:

[0122] S602, when the steering system performs software function related to the energy consumption level, the steering system does not perform the power consumption.

[0123] S603, when the steering system performs multiple steering assist modes related to the energy consumption level, the steering system performs the power consumption.

[0125] As shown in Figure 7 , the method for determining whether to perform power consumption when an execution system is a braking system comprises the following steps:

[0126] S701, if the execution system is a braking system, when the braking system performs hardware energy consumption related to the energy consumption level, the braking system performs the power consumption, wherein the special working condition comprises an over-the-air working condition.

[0127] S702, when the braking system performs hardware energy consumption related to the energy consumption level, the braking system does not perform the power consumption.

[0128] S703, when the braking system performs vehicle function related to the energy consumption level, the braking system does not perform the power consumption.

[0129] S704, when the braking system performs multiple assist modes related to the energy consumption level, the braking system performs the power consumption.

[0130] Please refer to Figure 8 is a flowchart of a method for determining whether to perform power consumption when an execution system is a thermal management system according to an embodiment of the present application;

[0131] As shown in Figure 8As shown, the judgment method of whether to execute power consumption when the execution system is a thermal management system comprises the following steps:

[0132] S801, if the execution system is a thermal management system, when the thermal management system executes the energy consumption level related to the control of hardware energy consumption under special working conditions, the thermal management system executes the power consumption;

[0133] S802, if when the thermal management system executes the energy consumption level related to the control of energy consumption by associating multiple air conditioning system modes, the thermal management system executes the power consumption;

[0134] S803, when the thermal management system executes the energy consumption level related to limiting the function of the power system to control energy consumption, the thermal management system does not execute the power consumption.

[0135] In summary, the supportability of the vehicle power system is analyzed. The function use scene and internal energy consumption management design of the component system are analyzed and discussed with the component hardware and software design engineers, and the energy consumption level support list of the component is formed, as shown in the following table:

[0146] According to the above energy consumption level definition, combined with the actual status of the hardware or software of each electrical appliance and the "energy consumption level support list" obtained in S2, the energy consumption level development item of each electrical appliance is defined, and finally the "controller-energy consumption level list" of the vehicle level is summarized, the main contents of which are as follows:

[0147]

[0148]

[0149] According to the setting requirements of the "controller-energy consumption level list", the energy consumption level development requirements of all electrical appliances are prepared. The contents at least include communication protocol, system interaction logic, energy consumption level development content, etc.

[0150] Among them, SOC (System-on-a-Chip) generally refers to system-level chip, also known as system on chip. MCU (Microcontroller Unit) is also called single chip microcomputer or single chip microcomputer. It is to reduce the frequency and specifications of central processing unit (CPU), and integrate memory, counter, USB, A / D conversion, UART, PLC, DMA and even LCD drive circuit on a single chip to form a chip-level computer for different application scenarios.

[0151] XCU is the control center of vehicle motion domain, XCU is the computing center of vehicle motion domain, and XCU is the integration center of network function of vehicle motion domain (Connect). The following is an example of XCU, and the communication protocol is as follows:

[0152]

[0153] Send energy consumption level request: After analyzing the energy consumption level requirements of each electrical appliance, the intelligent power distribution management unit requests the XCU to enter the corresponding energy consumption level through the CAN signal;

[0154] Execute energy consumption level request: After the XCU receives the energy consumption level request of the VIU, it determines whether the execution condition of its own system is met. If it is met, it executes and feeds back the execution success state. If it is not met, it does not execute and feeds back the execution failure state, and sends the failure reason to the intelligent power distribution unit.

[0155] Execute state forwarding: The intelligent power distribution unit receives and forwards the energy consumption level execution state of the execution system to the scene recognition and energy consumption level management system.

[0156] The development content of each execution system includes the energy consumption level of the electrical appliance, and the definition of each energy consumption level. The development requirements of the electrical appliance energy consumption level are as follows:

[0157] Function name: precondition; intelligent level state definition-XX controller: the controller has woken up; the controller XX function is not activated.

[0161] The development definition of the internal energy consumption level of the electrical appliance is as follows:

[0162]

[0163]

[0164] Please refer to Figure 9 , which is one of the flowcharts of the method for judging the scene mode of the vehicle based on vehicle state information provided by an embodiment of the present application;

[0165] As shown in Figure 9 , in an embodiment, the method for judging the scene mode of the vehicle based on vehicle state information includes the following steps:

[0166] S901, if the vehicle state information is identified as the power system not activated, it is determined that the vehicle is in a parking mode; S902, if the vehicle state information is identified as the vehicle being locked and powered off for more than a preset time or being remotely and actively activated to enter after being locked and powered off, it is determined that the vehicle is in a business trip mode; S903, if the vehicle state information is identified as the vehicle being locked and powered off within the preset time and without remotely and actively entering the business trip mode, it is determined that the vehicle is in a rapid start mode; S904, if the vehicle state information is identified as charging or intelligent power supplement request, it is determined that the vehicle is in a charging mode.

[0167] Please refer to Figure 10 , which is a flowchart of a method for determining a scene mode of a vehicle based on vehicle state information according to an embodiment of the present application;

[0168] As shown in Figure 10 , in an embodiment, the method for determining a scene mode of a vehicle based on vehicle state information includes the following steps:

[0169] S1001, if the vehicle state information is identified as an over-the-air download state being valid, it is determined that the vehicle is in an over-the-air download mode; S1002, if the vehicle state information is identified as a sentry mode being turned on, it is determined that the vehicle is in a sentry mode; S1003, if the vehicle state information is identified as an over-the-air download state being valid, it is determined that the vehicle is in an over-the-air download mode; S1004, if the vehicle state information is identified as a camping mode being turned on, it is determined that the vehicle is in a camping mode.

[0170] It should be noted that the KL15 power supply, this signal is supplied by the total electrical box in the car, through the fuse to each ECU KL15 pin. When the car key is twisted to the ON position (OFF-ACC-ON-CRANK-ON), or after a one-key start is pressed and released, the vehicle starts, and most ECUs (Electronic Control Unit) need to work in the vehicle starting state, such as chassis system ECU, ABS (antilock brake system), ESP (Electronic Stability Program), ABM (Asynchronous Balanced Mode), etc. Of course, some ECUs can work when the transmitter is not started (corresponding to the ACC position of the car keyhole), such as the instrument controller IP (instrument panel), the car entertainment system HUT (i.e. flat panel display), etc. Some places define this state as KL15R (R indicates Radio). Evolution of KL15 signal: with the development of automobile electronics, the advantages of CAN are becoming more and more obvious, replacing the dense wire harness on the car. As a result, there is a trend of replacing KL15 power with CAN signal. When the OFF, ACC (i.e. power switch), ON, CRANK (i.e. engine) signals are sent on the CAN bus, each ECU enters a sleep state or a normal working state according to the needs. The one-key start press in the off state is equivalent to the car key being turned to the ON position (IG ON), and the one-key start light press in the off state is equivalent to the car key being turned to the ACC position (IG OFF). The one-key start press in the starting state is equivalent to the car key being turned to the OFF position. KL15 signal is not smartly triggered by key or one-key start. Today, with the increasing intelligence of cars, not only can the car be started remotely by the car key, but also can the car be started remotely by the mobile phone APP, and even can the car be started automatically by the automatic driving car.

[0171] See Figure 11 , Figure 3 is a flowchart of a method for determining a scene mode of a vehicle based on vehicle state information according to an embodiment of the present application;

[0172] As Figure 11 shown, in an embodiment, the method for determining a scene mode of a vehicle based on vehicle state information includes the following steps:

[0173] S1101, if the vehicle state information is identified as the whole vehicle power state is KL15 open and the super energy saving mode is open, it is judged that the vehicle is in the super energy saving mode; S1102, if the vehicle state information is identified as the whole vehicle power state is KL15 open and the super energy saving mode is not open and the economic mode is open, it is judged that the vehicle is in the economic mode; S1103, if the vehicle state information is identified as the whole vehicle power state is KL15 open and the super energy saving mode is not open and the comfortable mode is open, it is judged that the vehicle is in the comfortable mode; S1104, if the vehicle state information is identified as the whole vehicle power state is KL15 open and the super energy saving mode is not open and the sports mode is open, it is judged that the vehicle is in the sports mode.

[0174] Please see Figure 12 , the fourth flow chart of the method for judging the scene mode of the vehicle based on the vehicle state information provided by an embodiment of the application;

[0175] As Figure 12 shown, in an embodiment, the method for judging the scene mode of the vehicle based on the vehicle state information comprises the following steps:

[0176] S1201, if the vehicle state information is identified as the whole vehicle power state is KL15 closed and no function is open and the network is not hibernated, it is judged that the vehicle is in the network abnormal mode; S1202, if the vehicle state information is identified as the low-voltage power supply system power supply, it is judged that the vehicle is in the low battery mode.

[0177] According to the scene mode, the preset energy consumption level request is sent to the intelligent power distribution management system, which comprises: when it is identified that the scene mode is more than two scenes, the energy consumption level request of the maximum power consumption in the two or more scenes is sent to the intelligent power distribution management system, wherein each scene is mapped to the corresponding energy consumption.

[0178] In summary, the scene recognition and energy consumption level management system mainly collects and analyzes the environment and vehicle state information of the vehicle, and then judges the scene mode of the vehicle according to the state information. Finally, according to the scene mode, the preset energy consumption management level request of each power consumption system is sent, and the energy consumption level execution and energy consumption information of these power consumption systems are accepted and recorded, and the low-voltage total energy consumption of the vehicle and the low-voltage energy consumption information of each subsystem are displayed.

[0179] The judgment basis of scene recognition mainly includes vehicle speed, braking state, vehicle driving mode, special function demand, vehicle power state, driver operation state, vehicle function state, special electrical demand of each power consumption system, vehicle power battery state, remote control and other information. According to the result of scene recognition, the preset energy consumption level request is sent to the power consumption system.

[0180] The technical solution will involve the demand analysis domain controller, intelligent power distribution management domain controller and vehicle electrical execution system such as body control system, chassis control system, power control system, thermal management control system.

Based on the recognized vehicle state information, the corresponding power supply level requirements are matched, and then the power supply level requirements are sent to the intelligent power distribution management system. The intelligent power distribution management system sends the power supply level to the execution system, and the execution system executes the function or load limitation. The execution system feeds back the execution state to the intelligent power distribution management system, and the intelligent power distribution management system forwards the execution state to the scene recognition and energy consumption level management system. It should be noted that the intelligent power distribution management system can also perform power-off control on each execution system. The intelligent power distribution management system can also perform current monitoring and energy consumption calculation, and feed back the energy consumption situation to the scene recognition and energy consumption level management system.

It should be noted that if it is power off, the intelligent power distribution management unit in the distribution layer acts as an executor to execute power off for each electrical appliance.
