Embodiment 1

Figure 1 is a flow chart of a vehicle controller control method provided according to Embodiment 1 of the present application. This embodiment can be applied to the situation of controlling the vehicle controller. The method can be executed by the control device of the vehicle controller. , the control device of the vehicle controller can be implemented in the form of hardware and/or software.

As the trend of vehicle intelligence and electrification gradually accelerates, there are more and more electrical loads in the vehicle. The vehicle's electrical load power consumption is large when idling or driving, a large proportion of which is composed of many standby loads with no working requirements. Composition of current. The source of power supply for the load of the vehicle can vary according to the vehicle. For example, on a fuel vehicle, the load of the vehicle is the electrical energy provided by the generator, and the final energy source is fuel; on an electric vehicle, the load of the vehicle is The final energy source of the electric energy provided by a DC-to-DC (Direct Current-Direct Current, DCDC) power supply is the power of the power battery. To sum up, excess load power consumption will bring unnecessary fuel consumption or mileage consumption. In addition, in the daily use of the car, many loads are not used frequently, but they still consume electric energy in the power grid with high power consumption.

The current mainstream power distribution method is: when the vehicle is idling or driving, even loads with no functional requirements are still connected to the vehicle power grid to consume the vehicle's electric energy, and the network management strategy of most vehicles is that all network nodes sleep together. In the form of wake-up, once the load is woken up, it will be in a standby mode with high power consumption even if there is no work requirement.

As a result, some vehicles perform segmented network management of the vehicle load according to different network segments when the ignition switch is turned off, and control some loads that are not required to quickly enter the dormant state according to the network segment, reducing the energy consumption of the battery. Such as power system, steering system, and braking system, etc. Although this control strategy can also achieve the purpose of energy saving, it has great scene limitations and small energy saving contribution. Moreover, this method is difficult to design the network topology. It must be ensured that loads on the same network segment sleep and wake up at the same time.

In addition, some vehicles also adopt the form of distributed gateways, combining similar controllers and distributed gateways to form a subnet subsystem. The subnet subsystem uses a local area network to communicate with other subnet subsystems through subgateway routing. When a When the subnet subsystem meets the sleep conditions, it can sleep independently without affecting the work of other subnet subsystems. Therefore, when the load in a subnet has no functional requirements, the subnet can be put into sleep first. However, the subnet of this solution The division is difficult and the scene has great limitations.

Based on this, the control method of the vehicle controller provided by this application is different from the traditional sleeping and waking up strategy for the entire network segment, the network management of sub-network segments, and the distributed network topology architecture. In the electrical load wake-up phase, the controller enters the shallow sleep mode through a specific network management sleep message, and the controller exits the shallow sleep mode through a specific network management wake-up message, so as to achieve without changing the vehicle network topology. Shallow sleep wake-up control for electrical loads.

As shown in Figure 1, the method includes the following steps.

S110. Obtain at least one first status signal sent by at least one first controller, where the first status signal is used to indicate the corresponding status of the vehicle.

The first controller can be understood as a controller in the vehicle that is connected to the central gateway controller and is used to send a corresponding first status signal to indicate the corresponding status of the vehicle. The type and number of the first controllers are not limited. For example, the first controller may be an engine controller. Accordingly, the first status signal sent by the engine controller may be the status of the engine to indicate whether the vehicle is in an idle state.

In this step, at least one first status signal sent by at least one first controller can be obtained to perform subsequent steps according to the vehicle status indicated by the at least one first status signal. The method of obtaining the first status signal will not be discussed here. Limitation, for example, the first status signal can be obtained in real time through the bus, etc.

S120. If at least one first status signal sent by all the first controllers indicates that the status of the vehicle satisfies the first preset status, obtain the second status signal of the load switch in real time. The second status signal is used to represent Whether the load switch is in a closed state or inactive state.

The first preset state can be considered as a preset vehicle state, which can be determined by the system or relevant personnel. For setting, the first preset state may include one or more preset states, and the preset state may correspond to obtaining the first state signal. The load switch can refer to the switch corresponding to the load connected to the vehicle. The type of load switch is not limited, such as a seat ventilation and heating switch. The second status signal can be understood as a signal sent by the load switch to the central gateway controller. Use To represent whether the load switch is in a closed state or inactive state, for example, the second state signal can be code information or digital information. For example, when the second status signal is 0, it can indicate that the load switch is in a closed state; when the second status signal is 1, it indicates that the load switch is not in a closed state, that is, it is in an on state; or if the value obtained at the current moment The second state signal is 1, and the second state signal obtained at the next moment is still 1, indicating that the load switch is in a non-action state; or if the second state signal obtained at the current moment is 1, the second state signal obtained at the next moment The signal is 2, indicating that the load switch is in an action state, that is, whether the load switch is in a non-action state or an action state needs to be judged based on at least two consecutive second state signals.

After obtaining the first status signal sent by the first controller, all obtained first status signals can be judged to perform corresponding operations according to the judgment results. For example, if at least one first status signal sent by all first controllers indicates that the status of the vehicle satisfies the first preset status, the second status signal of the load switch is obtained in real time; otherwise, the operation ends.

For example, when the number of first controllers is two, such as the body controller and the engine controller, the vehicle power supply status (i.e., the first status signal) sent by the body controller can be obtained respectively, and the vehicle power status signal sent by the engine controller can be obtained respectively. Engine status (i.e., the first status signal), the vehicle power supply status indicates the corresponding power supply status of the vehicle, such as the power-on status, and the engine status indicates the corresponding engine status of the vehicle, such as the idling status; and the first preset status includes the power-on status and the idling status. , that is, the obtained vehicle power supply status indicates the status of the vehicle and the engine status indicates the status of the vehicle both satisfy the first preset status, so the second status signal of the load switch can be obtained in real time.

S130. If the second status signal obtained in real time indicates that the load switch is in a closed state or inactive state, send a shallow sleep signal to control the second controller corresponding to the load switch to enter a shallow sleep state.

The signal for entering shallow sleep may be a signal for controlling the second controller corresponding to the load switch to enter a shallow sleep state. The second controller is the controller corresponding to the load switch and can control the load. The shallow sleep state can be considered as a special state between the full sleep state and the standby state. That is, the power consumption of the load in the shallow sleep state is much smaller than that in the standby state, and the quiescent current is a little larger than that in the full sleep state. In this state, almost all functions of the load are turned off, leaving only some modules working to receive signals to exit shallow sleep.

In this embodiment, if the second status signal obtained in real time indicates that the load switch is in a closed state or inactive state, it means that the second controller corresponding to the current load switch has no demand for use. At this time, it can A shallow sleep signal is sent to control the second controller to enter a shallow sleep state, that is, the second controller can control the second controller itself and the corresponding load to enter a shallow sleep state; if the second state signal obtained in real time represents The load switch is in the on state or in the action state, indicating that the second controller corresponding to the current load switch has a demand for use. No operation is performed at this time, and the judgment of the second state signal obtained in real time is continued.

Among them, the second state signal obtained in real time represents that the load switch is in a closed state. It can be understood that the second state signal obtained at the current moment represents that the load switch is in a closed state. It can also be considered as the second state signal obtained at each moment within a predetermined time period. Both state signals represent that the load switch is in a closed state; the second state signal obtained in real time represents that the load switch is in a non-action state, which can be considered as all second state signals obtained within a predetermined time period or between adjacent moments. If they are the same, that is, there is no difference between the multiple second state signals, then the load switch is in a non-action state. The predetermined time period can be determined by empirical values and is not limited here. Different control steps may be corresponding to different loads, which is not limited in this embodiment.

An embodiment of the present application provides a control method for a vehicle controller that obtains at least one first status signal sent by at least one first controller, and the first status signal is used to indicate the corresponding status of the vehicle; if all third If at least one first status signal sent by a controller indicates that the status of the vehicle satisfies the first preset status, the second status signal of the load switch is obtained in real time. The second status signal is used to characterize whether the load switch is in a closed state or inactive state; if the second state signal obtained in real time indicates that the load switch is in a closed state or inactive state, a shallow sleep signal is sent to control the second controller corresponding to the load switch to enter Light sleep state. Using this method, by judging the first status signal sent by the first controller, when all the first status signals indicate that the status of the vehicle meets the first preset status, the second status signal of the load switch can be accurately obtained, and at the same time , when the second state signal indicates that the load switch is in a closed state or inactive state, the shallow sleep signal is sent, which realizes the control of the second controller to enter the shallow sleep state without changing the vehicle network topology, thus Reduce unnecessary load consumption.

In one embodiment, the first controller includes a body controller, an energy management controller, an engine controller and/or a vehicle controller;

If at least one first status signal sent by all first controllers indicates that the status of the vehicle satisfies the first preset status, obtaining the second status signal of the load switch in real time includes:

If the first status signal sent by the vehicle body controller indicates that the vehicle power supply is in the powered-on state, the first status signal sent by the engine controller indicates that the engine is in idling state, and the first status signal sent by the vehicle controller indicates When the vehicle is in a high-voltage power-on state, and/or the first state signal sent by the energy management controller indicates that the power grid state is in the output state, the second state signal of the load switch is obtained in real time.

The first controller may be determined according to the type of vehicle. For example, when the vehicle is a fuel vehicle, the first controller may include a body controller, an energy management controller and/or an engine controller; when the vehicle is an electric vehicle, the first controller may A controller may include a body controller, an energy management controller, and/or a vehicle controller. After the first controller is determined, at least one first status signal sent by at least one included controller can be judged to obtain the second status signal of the load switch in real time. Different loads can also correspond to different acquisition methods, which can be determined according to the actual situation.

For example, when the first controller includes a body controller, an energy management controller, and an engine controller, the first status signals sent by the body controller, the energy management controller, and the engine controller can be acquired and judged respectively, If the first status signal sent by the body controller indicates that the vehicle power supply is in the power-on state, the first status signal sent by the engine controller indicates that the engine is in the idle state, and the first status signal sent by the energy management controller indicates that the grid status is in the output state , then obtain the second status signal of the load switch in real time; otherwise, continue to judge at least one first status signal until at least one first status signal indicates that the status of the vehicle meets the first preset status, obtain the load switch in real time. Second status signal.

Similarly, when the first controller includes a body controller, an energy management controller and a vehicle controller, the first status signals sent by the body controller, energy management controller and vehicle controller can be acquired and judged respectively. , if the first status signal sent by the body controller indicates that the vehicle power supply is in the power-on state, the first status signal sent by the vehicle controller indicates that the vehicle is in the high-voltage power-on state, and the first status signal sent by the energy management controller indicates that the power grid The state is in the output state, then obtain the second state signal of the load switch in real time; otherwise, continue to judge at least one first state signal until at least one first state signal indicates that the state of the vehicle meets the first preset state, real-time Obtain the second status signal of the load switch.

In one embodiment, if at least one first status signal sent by all first controllers indicates that the status of the vehicle satisfies the first preset status, obtaining the second status signal of the load switch in real time includes:

If at least one first state signal sent by all first controllers indicates that the state of the vehicle satisfies the first preset state, obtain a third state signal sent by the electronic stability controller or the motor controller in real time;

If the currently acquired third state signal satisfies the second preset state, the second state signal of the load switch is acquired in real time.

In this embodiment, the third status signal may refer to a signal sent by the electronic stability controller or the motor controller, and is used to indicate the driving status of the vehicle, such as the driving speed of the vehicle.

The second preset state is similar to the first preset state and can be considered as a preset vehicle state. The system or relevant personnel perform settings. The second preset state may include one or more preset states. The preset state may correspond to obtaining the third state signal. The second preset state and the first preset state are only In order to distinguish different objects, this embodiment does not limit this.

For example, when at least one first status signal sent by all first controllers indicates that the status of the vehicle satisfies the first preset status, the third status signal sent by the electronic stability controller or the motor controller can be obtained in real time; and then Determine whether the acquired third state signal satisfies the second preset state. If the currently acquired third state signal satisfies the second preset state, it means that the currently acquired third state signal satisfies the preset vehicle state. This The second state signal of the load switch can be acquired in real time; if the currently acquired third state signal does not satisfy the second preset state, subsequent operations will be stopped.

In one embodiment, the third state signal includes vehicle speed, motor speed and/or vehicle gear. Correspondingly, if the currently acquired third state signal satisfies the second preset state, the load switch is acquired in real time. The second status signal includes:

When the vehicle speed or the motor speed is equal to zero and the vehicle gear is in parking gear or neutral, the second status signal of the load switch is obtained in real time.

In this step, the third status signal may include vehicle speed, motor speed and/or vehicle gear. The vehicle speed is the driving speed of the vehicle, the motor speed is the rotation speed of the vehicle engine, and the vehicle gear is the current gear of the vehicle. . The third state signal may be determined according to the type of vehicle. For example, when the vehicle is a fuel vehicle, the third state signal may include motor speed and vehicle gear; when the vehicle is an electric vehicle, the third state signal may include vehicle speed and Vehicle gear. Correspondingly, after determining the third state signal, the currently obtained third state signal can be judged, that is, when the vehicle speed or motor speed is equal to zero, and the vehicle gear is in parking gear or neutral, the third state signal of the load switch can be obtained in real time. 2 status signal; otherwise stop subsequent operations.

In one embodiment, if the second status signal obtained in real time indicates that the load switch is in a closed state or an inactive state, then a shallow sleep signal is sent to control the second controller corresponding to the load switch to enter Light sleep state, including:

Within the preset time period, if the vehicle speed or motor speed obtained in real time is equal to zero, and the vehicle gear obtained in real time is in parking gear or neutral, and all the second state signals obtained in real time indicate that the load switch is If the controller is in the off state, a light sleep signal is sent to control the second controller to enter the light sleep state.

The preset time period can be considered as a time period starting from the current moment and taking the preset time as the interval. The preset time can be determined by an empirical value, for example, the preset time can be 5 minutes.

In this embodiment, all real-time third state signals and second state signals obtained in real time within a preset time period can be judged, and corresponding operations can be performed based on the judgment results. For example, if in advance Assume that within the time period, the vehicle speed or motor speed obtained in real time is equal to zero, and the vehicle gear obtained in real time is in parking or neutral, and all second state signals obtained in real time indicate that the load switch is in a closed state, then it can be sent Enter the shallow sleep signal to control the second controller to enter the shallow sleep state; otherwise, the timing will be restarted to judge the third state signal and the second state signal in the next preset time period. On this basis, by judging the vehicle speed, motor speed, vehicle gear and second state signals within the preset time period, the correctness of sending the shallow sleep signal is ensured.

Embodiment 2

FIG. 2 is a flow chart of a vehicle controller control method provided according to Embodiment 2 of the present application. Embodiment 2 is explained based on the above-mentioned embodiments. In this embodiment, an entry into shallow sleep signal is sent to control the situation after the second controller corresponding to the load switch enters the shallow sleep state, including: if the second state signal obtained in real time indicates that the load switch is on If there is an action state, an exit light sleep signal is sent to control the second controller corresponding to the load switch to exit the light sleep state.

Please refer to Embodiment 1 for contents that are not described in detail in this embodiment.

As shown in Figure 2, a control method for a vehicle controller provided by Embodiment 2 of the present disclosure includes the following steps.

S210. Obtain at least one first status signal sent by at least one first controller, where the first status signal is used to indicate the corresponding status of the vehicle.

S220. If at least one first status signal sent by all the first controllers indicates that the status of the vehicle satisfies the first preset status, obtain the second status signal of the load switch in real time. The second status signal is used to represent Whether the load switch is in a closed state or inactive state.

S230. If the second status signal obtained in real time indicates that the load switch is in a closed state or an inactive state, send a shallow sleep signal to control the second controller corresponding to the load switch to enter a shallow sleep state.

S240. If the second status signal obtained in real time indicates that the load switch is in an on state or in an action state, send an exit shallow sleep signal to control the second controller corresponding to the load switch to exit the shallow sleep state.

The signal for exiting the shallow sleep state may be a signal for controlling the second controller corresponding to the load switch to exit the shallow sleep state.

After the second controller corresponding to the load switch enters the shallow sleep state, it is still necessary to obtain and judge the second state signal in real time. When the second state signal indicates that the load switch is in the on state, or When the second state signal at the current moment is different from the second state signal at the previous moment, or all the second state signals obtained within the preset time period are not the same, it is necessary to send an exit light sleep signal to control the load switch The corresponding second controller exits the shallow sleep state; when the second state signal indicates that the load switch is not in the on state, or the second state signal at the current moment is still the same as the second state signal at the previous moment, or at the preset time All the second state signals obtained in the segment are exactly the same, that is, when they are still in the closed state or inactive state, the second controller corresponding to the load switch will still be kept in the shallow sleep state until the second state signal obtained represents the load switch. When it is in the on state or in the action state, a shallow sleep exit signal is sent to control the second controller corresponding to the load switch to exit the shallow sleep state.

The control method of the vehicle controller provided in the second embodiment of the present application can, after the second controller corresponding to the load switch enters the shallow sleep state, judge the second state signal obtained in real time, and the second state signal can represent the load. When the switch is in an on state or in an action state, a light sleep exit signal is sent, thereby controlling the second controller to exit the light sleep state.

In one embodiment, when the second controller is an ambient light controller, after sending an exit shallow sleep signal to control the second controller corresponding to the load switch to exit the shallow sleep state, the method further includes:

Obtain the light intensity signal collected by the sunlight sensor in real time;

If the light intensity signal obtained in real time is greater than the first light intensity threshold, a shallow sleep signal is sent to control the second controller to enter a shallow sleep state;

After the second controller enters the shallow sleep state, if the light intensity signal obtained in real time is less than the second light intensity threshold, an exit shallow sleep signal is sent to control the second controller to exit the shallow sleep state.

Among them, the light intensity signal can be used to characterize the intensity of the current illumination; the first light intensity threshold can be considered as the maximum critical value of light intensity, which can be preset by relevant personnel; the second light intensity threshold can be considered as the minimum critical value of light intensity. The first light intensity threshold is greater than the second light intensity threshold. The value can be set according to the actual situation and is not limited here.

In the embodiment, when the second controller is an ambient light controller, and after the second controller corresponding to the load switch exits the shallow sleep state, the light intensity signal collected by the sunlight sensor can be obtained in real time, and based on the size of the light intensity signal, Adaptive adjustment, for example, when the light intensity signal obtained in real time is greater than the first light intensity threshold, it means that the current light intensity is greater than the maximum threshold of the preset light intensity. At this time, a shallow sleep signal can be sent to control The second controller enters a shallow sleep state to reduce power consumption; when the light intensity signal obtained in real time is less than the second light intensity threshold, it means that the current light intensity is greater than the minimum threshold of the preset light intensity, and an exit needs to be sent at this time Shallow sleep signal to control the second controller to enter normal working state. On this basis, the working state of the second controller can be controlled in real time according to the size of the light signal, reducing unnecessary load consumption.

From the above description, it can be found that the control method of the vehicle controller provided by the embodiment of the present application can be classified and controlled according to different load characteristics, environmental characteristics, and user usage scenarios. Through special network management, the load without work requirements can be controlled from The standby state enters a shallow sleep state with lower energy consumption, which ensures that the unnecessary consumption of electrical loads is minimized without affecting the user's perception of use, and solves some non-functional requirements of the vehicle when idling or driving. The load power consumption indirectly increases the fuel consumption of fuel vehicles and reduces the driving range of electric vehicles.

Figure 3 is a system block diagram of shallow sleep network management provided according to Embodiment 2 of the present application. As shown in Figure 3, the implementation of the shallow sleep network management method of the present application relies on the network system of the vehicle. The network system of the vehicle is composed of the body Controllers, engine controllers or vehicle controllers, energy management controllers, electronic stability controllers or motor controllers, transmission controllers, air conditioning controllers, sunlight sensors, multiple function switches, central gateway controllers and controlled The controlled electrical loads include seat controllers, seat environment controllers, air conditioning controllers, ambient light controllers, heads-up display controllers, lighting controllers, etc.

The central gateway controller performs status judgment through input signals such as the body controller, engine controller, or vehicle controller, and energy management controller (i.e., the first status signal) to determine whether the network management control conditions for entering shallow sleep wake-up are met. When the conditions are met, the logical judgment of sending the shallow sleep entry signal and the shallow sleep exit signal is made through the actual scenario. The central gateway controller sends the specific shallow sleep entry signal and shallow sleep exit signal to the bus, and multiple controlled electrical loads After receiving the corresponding signal, the entry and exit of the shallow sleep state is executed.

The following is an exemplary description of the control method of the vehicle controller provided by the embodiment of the present application: as follows, the control method of the vehicle controller can be divided into: confirmation of entry conditions of shallow sleep network management, logical judgment of shallow sleep network management, shallow sleep Execution of network management.

1) Confirmation of entry conditions for shallow sleep network management:

Figure 4 is a logical block diagram of shallow sleep network management entry conditions provided according to Embodiment 2 of the present application. As shown in Figure 4, the central gateway controller determines the entire system according to the vehicle power status (i.e., the first status signal) sent by the body controller. Whether the vehicle power supply status is in the powered-on state. If the vehicle power supply status is in the powered-on state, the entry conditions for shallow sleep network management are met;

For fuel vehicles: the central gateway controller determines whether the vehicle is in an idling state based on the engine status (i.e., the first status signal) sent by the engine controller. If so, the entry conditions for shallow sleep network management are met; for electric vehicles: the central gateway controller The gateway controller determines whether the vehicle is in the Ready state based on the high-voltage power-on status (i.e., the first status signal) sent by the vehicle controller. If so, the entry conditions for shallow sleep network management are met;

The central gateway controller determines whether the generator or DCDC is in the output state based on the grid status signal (i.e. the first status signal) in the energy management controller. If so, the entry conditions for shallow sleep network management are met.

When the above judgment conditions are met (that is, at least one first status signal sent by all the first controllers indicates that the state of the vehicle meets the first preset state), it means that the vehicle meets the entry conditions of shallow sleep network management, and accordingly "Status signal Q" will be set, and the vehicle can enter the logical judgment of shallow sleep network management.

2) Logical judgment of shallow sleep network management:

When the vehicle meets the entry conditions of shallow sleep network management, the central gateway controller will control all controlled loads based on the shallow sleep network management logic and output the shallow sleep entry or exit signal of the corresponding controller. The control logic of some controlled loads is described below. Other controlled loads not mentioned can also be controlled according to the method of this application according to the environmental status and usage scenarios.

Figure 5 is a logical block diagram of shallow sleep network management of the seat controller provided according to Embodiment 2 of the present application. As shown in Figure 5, after the "signal Q" that the vehicle meets the entry conditions for shallow sleep network management is set, the central The gateway controller starts timing. When the timing time exceeds 5 minutes, and within 5 minutes, there is no change in the status of the seat adjustment signal (that is, the second status signal of the load switch is obtained in real time, and the second status signal indicates that the load switch is in a non-function state. action state), that is, the user has no seat adjustment action, then the seat controller is sent a shallow sleep entry instruction "signal A" (that is, a shallow sleep entry signal is sent to control the second controller corresponding to the load switch to enter the shallow sleep state ); If within 5 minutes, there is a change in the status of the seat adjustment signal, the timing will stop until the seat adjustment signal changes back to the initial value and the timing will be restarted; if the seat controller is in shallow sleep and the user has the intention to adjust the seat, the seat adjustment The switch sends an adjustment signal to the central gateway controller. After the central gateway controller receives the signal setting of the seat adjustment switch (that is, the obtained second status signal indicates that the load switch is in an action state), the central gateway controller sends the seat to the bus. The controller shallow sleep exit command "signal a" (that is, sending a shallow sleep exit signal to control the second controller corresponding to the load switch to exit the shallow sleep state). The seat adjustment switch and the seat controller are decoupled.

Figure 6 is a logical block diagram of shallow sleep network management of the seat environment controller provided according to Embodiment 2 of the present application. As shown in Figure 6, after the "signal Q" is set when the vehicle meets the entry conditions of shallow sleep network management, The central gateway controller starts timing. When the timing exceeds 5 minutes, and within 5 minutes, the seat ventilation and heating and other related function signal display functions are in a closed state (that is, the second status signal of the load switch is obtained in real time, and the second status signal Indicating that the load switch is in a closed state), that is, there is no need for use of the seat environment controller, the central gateway controller sends the seat environment controller shallow sleep entry instruction "signal B" (that is, sends a shallow sleep signal to control all The second controller corresponding to the load switch enters a shallow sleep state); if within 5 minutes, the seat ventilation and heating and other related function signals are on, the timing will end until the seat ventilation and heating and other related function signals are off and the time will be restarted. ; Such as seat environment controller After light sleep, if the user intends to use seat ventilation and heating, the seat ventilation and heating switch sends a function enable signal to the central gateway controller, and the central gateway controller receives the function signal setting of the seat ventilation and heating switch (that is, the obtained After the second status signal indicates that the load switch is in the on state), the seat environment controller shallow sleep exit command "signal b" is sent to the bus (that is, the shallow sleep exit signal is sent to control the second control corresponding to the load switch The processor exits shallow sleep state). The seat ventilation and heating switch is decoupled from the seat environment controller.

Figure 7 is a logical block diagram of the shallow sleep network management of the air conditioning controller provided according to Embodiment 2 of the present application. As shown in Figure 7, after the "signal Q" is set when the vehicle meets the entry conditions of the shallow sleep network management, the central gateway The controller starts timing. When the timing time exceeds 5 minutes, and within 5 minutes, the relevant signal of the air conditioning function shows that the air conditioner is in a closed state (that is, the second state signal of the load switch is obtained in real time, and the second state signal represents the load switch. is in the off state), that is, the user has no demand for air conditioning, then the air conditioning controller is sent a shallow sleep entry command "signal C" (that is, a shallow sleep signal is sent to control the second controller corresponding to the load switch to enter the shallow sleep state) ; If within 5 minutes, the relevant signal of the air conditioning function shows that the air conditioner is on, the timing will end, and the timing will be restarted until the relevant signal of the air conditioning function shows that the air conditioner is off. For example, after the air-conditioning controller is in light sleep and the user intends to use the air-conditioning, the air-conditioning control switch sends a function enable signal to the central gateway controller, and the central gateway controller receives the air-conditioning switch signal to set (that is, the obtained second state signal represents the After the load switch is in the on state), the air conditioning controller shallow sleep exit command "signal c" is sent to the bus (that is, a shallow sleep exit signal is sent to control the second controller corresponding to the load switch to exit the shallow sleep state). The air conditioning control switch and the air conditioning controller are decoupled.

As shown in Figure 8, after the "signal Q" is set when the vehicle meets the entry conditions of shallow sleep network management, the central The gateway controller determines the ambient light function turn-on signal. If the ambient light function is turned off (that is, the second state signal of the load switch is obtained in real time, and the second state signal indicates that the load switch is in a closed state), it sends a light signal of the ambient light control. Sleep enters the command "signal D" until it receives the function start signal from the ambient light switch. The central gateway controller sends the ambient light controller shallow sleep exit command "signal d" to the bus (i.e. sends a shallow sleep signal to control all The second controller corresponding to the load switch enters a shallow sleep state). If the ambient light function is turned on, the current light intensity signal (i.e. light intensity signal) collected by the sunlight sensor and the preset light intensity value X1 (i.e. the first light intensity threshold) and the preset light intensity value X2 (i.e. the second light intensity threshold) are intensity threshold), if the light intensity signal of the sunlight sensor is > Shallow sleep signal to control the second controller to enter shallow sleep state).

The sunlight sensor, ambient light switch and ambient light controller are decoupled.

As shown in Figure 9, after the "signal Q" is set when the vehicle meets the entry conditions of shallow sleep network management, the central gateway The controller determines the driving status of the vehicle through the electronic stability controller or motor controller (that is, real-time acquisition of the third state signal sent by the electronic stability controller or motor controller, the third state signal includes vehicle speed, motor speed and/or vehicle gear) , if the vehicle speed or motor speed ≠ 0, or the gear is not Park/Neutral (P/N), no logical judgment will be made for the lighting controller’s shallow sleep network management; if the vehicle speed or motor speed = 0, and the vehicle gear is P/N, then determine whether there is an active functional light turned on (that is, when the vehicle speed or the motor speed is equal to zero, and the vehicle gear is in parking or neutral, then obtain it in real time The second status signal of the load switch), such as low beam lights, fog lights, etc.; if there is an active functional light turned on, no logical judgment of the light controller shallow sleep network management will be made; if there is no active functional light turned on, then The 5-minute count starts when the vehicle speed or motor speed = 0 and the vehicle gear is P/N, and within 5 minutes, there is no change in vehicle speed or motor speed, and the gear position does not change, and at the same time, no active functional lights are turned on (that is, in the preset During the time period, if the vehicle speed or motor speed obtained in real time is equal to zero, and the vehicle gear obtained in real time is in parking or neutral, and all the second state signals obtained in real time indicate that the load switch is in a closed state ), the gateway controller sends the light controller's light sleep entry command "signal E" (ie, sends a light sleep entry signal to control the second controller to enter the light sleep state). If within 5 minutes, the vehicle speed or motor speed ≠ 0, or the gear is not P/N, the timing will end until the conditions are met and the timing will be restarted. For example, after the light controller is in shallow sleep, the vehicle speed or motor speed ≠ 0, or the gear is not P/N, or the user turns on the functional light through the combination switch (that is, the second state signal obtained indicates that the load switch is in On state), the central gateway controller sends the air conditioning controller shallow sleep exit command "signal e" to the bus (that is, sends an exit shallow sleep signal to control the second controller corresponding to the load switch to exit the shallow sleep state). The electronic stability controller or motor controller, transmission controller, combination switch and lighting controller are decoupled.

As shown in Figure 10, after the "signal Q" is set when the vehicle meets the entry conditions of shallow sleep network management, the central The gateway controller determines the head-up display function turn-on signal. If the head-up display function is turned on, shallow sleep network management will not be performed; if the head-up display function is turned off (that is, the second state signal of the load switch is obtained in real time, the second state signal represents the above load switch is in the off state), then send the shallow sleep entry command "signal F" of the heads-up display controller (that is, send the shallow sleep entry signal to control the second controller corresponding to the load switch to enter the shallow sleep state) until the When the head-up display control switch sends a head-up display function turn-on signal (that is, the obtained second status signal indicates that the load switch is in an on-state), the central gateway controller sends the head-up display controller shallow sleep exit command "signal f" to the bus. (i.e. send back A shallow sleep signal is generated to control the second controller corresponding to the load switch to exit the shallow sleep state). The head-up display control switch and the head-up display controller are in a decoupled state.

3) Execution of shallow sleep network management

For all controlled electrical loads, shallow sleep will be executed immediately after receiving the shallow sleep entry command "signal N" sent by the central gateway controller. The concept of shallow sleep is a special state between full sleep and standby state. In this state, the functions of the electrical load are almost completely shut down, leaving only some modules working to receive specific shallow sleep exit command "signals". n" (i.e. exit) and wake up the entire component. In this state, the power of the electrical load is much smaller than the standby power consumption, and a little larger than the final sleep quiescent current.
