It achieves precise control of the motor speed and torque through the inversion process in power electronics technology. The efficiency of the motor controller usually refers to the energy conversion efficiency of the motor controller in the process of converting the direct current provided by the battery into the alternating current required to drive the motor.

[0042] See also Figure 1 , is an energy consumption optimization control method provided in an embodiment of the present application. The execution subject of the method may be, but is not limited to, a motor controller. The motor controller includes a power module. The motor controller converts the direct current provided by the energy storage system into the alternating current required to drive the motor through the inversion process of the power module, so as to achieve precise control of the motor speed and torque. The energy consumption optimization method provided in this embodiment specifically includes the following steps:

[0043] Step S101: obtaining the gear status of the vehicle;

[0044] In one implementation, the gear state of the vehicle may be determined by acquiring the value of the control mode flag and judging the gear state of the vehicle according to the value of the control mode flag.

[0045] See also Figure 2In a specific embodiment, the vehicle controller sets a control mode flag IPU_VCU_Ctrlmode. When the vehicle controller detects that the driver has engaged the P gear (parking gear) or the N gear (neutral gear), the value of the control mode flag is set to 0, that is, IPU_VCU_Ctrlmode=0; when the vehicle controller detects that the driver has engaged the D gear (driving gear) or the R gear (reverse gear), the value of the control mode flag is set to 1, that is, IPU_VCU_Ctrlmode=1. Therefore, in this embodiment, the motor controller can directly identify the gear state of the vehicle by monitoring the value of the control mode flag IPU_VCU_Ctrlmode, that is, when it is detected that IPU_VCU_Ctrlmode=0, it is judged that the gear state of the vehicle is in the P gear or the N gear, and when it is detected that IPU_VCU_Ctrlmode=1, it is judged that the gear state of the vehicle is in the D gear or the R gear.

[0046] It should be noted that, in some other embodiments, the gear status of the vehicle can also be obtained by other means, such as the motor controller can receive the gear status information from the transmission control unit or other related control units through the CAN bus, or the transmission can directly send the gear status information to the motor controller through an electrical signal (such as a switch signal or a potentiometer signal), or the shift lever position sensor can detect the driver's shift operation and convert the shift information into an electrical signal and send it to the motor controller. The specific design can be adaptively designed according to different vehicle systems, and the present application does not limit the method of obtaining the gear status of the vehicle.

[0047] Step S102: determining the vehicle's motion mode according to the gear state, wherein the motion mode includes a static mode and a dynamic mode.

[0048] In one embodiment, when the gear state of the vehicle is the parking gear or the neutral gear, it is determined that the vehicle is in the static mode; when the gear state of the vehicle is the driving gear or the reverse gear, it is determined that the vehicle is in the dynamic mode.

[0049] In a specific embodiment, after the motor controller determines the gear state of the vehicle according to the value of the control mode flag IPU_VCU_Ctrlmode, it identifies the current motion mode of the vehicle according to the gear state of the vehicle. If the gear state of the vehicle is in P gear or N gear, the vehicle is judged to be in static mode. At this time, the power system (including the engine or motor) generally does not provide power and the vehicle does not move; if the gear state of the vehicle is in D gear or R gear, the vehicle is judged to be in dynamic mode. At this time, the power system will be ready to provide power to respond to the driver's throttle input to maintain normal operation of the vehicle.

[0050] In some other embodiments, the judgment conditions of the vehicle's motion mode also include: judging the vehicle's motion mode based on the input of the sensor, for example, when the vehicle speed signal provided by the vehicle speed sensor is zero, judging that the vehicle is in static mode, when the vehicle speed signal provided by the vehicle speed sensor is greater than zero, judging that the vehicle is in dynamic mode, and when a change in the acceleration signal provided by the acceleration sensor is detected, judging that the vehicle is in dynamic mode; judging the vehicle's motion mode based on the driver's operation, for example, when the accelerator pedal is in a stationary state and the brake pedal is pressed, judging that the vehicle is in static mode; judging the vehicle's motion mode based on the vehicle's current mode configured by the vehicle mode management module (VMM), for example, when the vehicle's current mode configured by the vehicle mode management module is in parking mode, judging that the vehicle is in static mode.

[0051] Step S103: When the vehicle is in static mode, if the execution conditions of the vehicle static energy consumption optimization strategy are met, the vehicle static energy consumption optimization strategy is executed.

[0052] Among them, the vehicle static energy consumption optimization strategy is an energy consumption optimization strategy executed by the motor controller when the vehicle is in a static mode, and the motor controller stops executing the energy consumption optimization strategy when the vehicle is not in a static mode.

[0053] In one embodiment, the execution condition in the vehicle static energy consumption optimization strategy is that no active heating request is received within a preset first time threshold. In other embodiments, the execution condition in the vehicle static energy consumption optimization strategy can also be other execution conditions set by the system or user that can perform energy consumption optimization.

[0054] In one embodiment, the vehicle static energy consumption optimization strategy is executed by controlling the switch device in the power module to enter the off state. In other embodiments, the vehicle static energy consumption optimization strategy can also be executed by other execution modes set by the system or the user that can optimize energy consumption.

[0055] In one embodiment, the judgment condition that no active heating request is received within a preset first time threshold includes: the motor active heating enable signal is in an invalid state, and the duration is greater than or equal to the preset first time threshold.

[0056] See also Figure 2In a specific embodiment, the motor controller sets a motor active heating enable signal MotorHeat_Enable, which is used to start the heating function of the motor under specific circumstances. For example, in cold climate conditions, the battery pack needs to be heated by the motor as a heating source to optimize the operating temperature of the battery and improve its charging and discharging performance; or when the temperature sensor built into the motor detects that the temperature is lower than a preset threshold, the motor active heating enable signal may be triggered; or when the vehicle is started, the motor active heating enable signal may be triggered to pre-heat the motor to reduce the impact of cold start on the motor and battery.

[0057] When the vehicle is in static mode, the motor controller will judge the state of the motor active heating enable signal. When the motor active heating enable signal MotorHeat_Enable = 0, and the duration is greater than or equal to the preset first time threshold (for example, 2 minutes), it is judged that the motor controller has not currently received an active heating request, and the motor controller generates a shutdown command for the power module to control the switch device in the power module to enter a continuous shutdown state, which can not only reduce the switching loss generated by the switch device during frequent switching, and the conduction loss caused by the conduction voltage drop when conducting, but also reduce heat loss by turning off the switch device, reduce cooling requirements, and improve the overall efficiency of the motor controller. It should be noted that after the switch device in the power module enters the shutdown state, the motor controller detects that the state of the motor active heating enable signal has changed, that is, when MotorHeat_Enable = 1, the switch device in the power module will re-enter the open state to respond to the vehicle's active heating request.

[0058] Step S104: When the vehicle is in the dynamic mode, if the execution conditions of the vehicle dynamic energy consumption optimization strategy are met, the vehicle dynamic energy consumption optimization strategy is executed.

[0059] The vehicle dynamic energy consumption optimization strategy is a strategy different from the vehicle static energy consumption optimization strategy. Specifically, in one embodiment, the execution condition of the vehicle dynamic energy consumption optimization strategy may be different from the vehicle static energy consumption optimization strategy.

[0060] In one embodiment, the execution condition of the vehicle dynamic energy consumption optimization strategy is that the vehicle is detected to be stationary. In other embodiments, the execution condition of the vehicle dynamic energy consumption optimization strategy can also be other execution conditions set by the system or the user that can perform energy consumption optimization.

[0061] In one embodiment, the vehicle dynamic energy consumption optimization strategy is executed by controlling the switch device in the power module to enter the off state. In other embodiments, the vehicle dynamic energy consumption optimization strategy can also be executed by other execution modes set by the system or the user that can optimize energy consumption.

[0062] In one embodiment, the judgment condition that the vehicle has a stationary tendency includes: the target speed in the motor speed signal is less than a preset speed threshold, and the target torque in the torque request signal is less than a preset torque threshold.

[0063] See also Figure 2 In a specific embodiment, when the vehicle is in dynamic mode, the motor controller monitors the motor speed signal and the received torque request signal in real time. When the target speed MtrSpd in the motor speed signal is detected to be less than the preset speed threshold (e.g., MtrSpd < 200rpm), and the target torque Torque_Rf in the torque request signal is less than the preset torque threshold (e.g., Torque_Rf < 3Nm), the motor controller generates a shutdown command for the power module to control the switch device in the power module to enter the shutdown state, thereby reducing the power consumption caused by the switch device and improving the overall efficiency of the motor controller. It should be noted that after the switch device in the power module enters the shutdown state, when the motor controller detects that the target speed MtrSpd in the motor speed signal is greater than or equal to the preset speed threshold, and / or detects that the target torque Torque_Rf in the torque request signal is greater than or equal to the preset torque threshold, the switch device in the power module will re-enter the open state to respond to the driver's acceleration request and prepare for vehicle acceleration.

[0064] In some other embodiments, the execution condition of the vehicle dynamic energy consumption optimization strategy also includes: judging that the vehicle has a parking demand under the current road conditions according to the change of the traffic signal. The judgment condition that the vehicle has a parking demand includes: the distance between the current position of the vehicle and the traffic light in the driving section is less than a preset distance threshold, and the traffic light will turn red within a preset time, wherein the preset time is less than a preset second time threshold.

[0065] In a specific embodiment, the motor controller can determine whether the vehicle needs to stop by the changing time of the traffic light provided by the on-board navigation system. When the distance between the vehicle and the nearest traffic light in the driving section is less than a preset distance threshold, and the traffic light is about to turn red within a preset second time threshold, it is determined that the vehicle is about to stop, and the switching device in the power module is controlled to enter the shutdown state in advance to reduce energy consumption before the stop line and improve the control efficiency of the motor controller.

[0066] In the embodiment of the present application, the execution conditions of the vehicle static energy consumption optimization strategy and the vehicle dynamic energy consumption optimization strategy can be set according to the specific vehicle usage scenario. When the vehicle does not need the motor to provide power output, the switch device in the power module can be turned off in time to reduce the switching loss, conduction loss and heat loss of the switch device during operation, so as to improve the efficiency of the motor controller, thereby improving the economy and cruising range of the whole vehicle. In addition, the energy consumption optimization control method provided in the embodiment of the present application can be applied to the motor controller, and only needs to rely on the motor controller (MCU) to identify the relevant signals and issue the control instructions, without frequent signal interaction with the vehicle controller (VCU). Therefore, the motor controller in the embodiment of the present application can replace the functions of part of the vehicle controller, and can save the signal interaction time between different controllers, thereby improving the response delay problem caused by signal interaction.

[0067] In an embodiment of the present application, the switching device in the power module can be an insulated gate bipolar transistor (IGBT), a metal oxide field effect transistor (MOSFET), or a high-performance high-voltage power switching device made of other materials, and the present application does not impose any restrictions on this.

[0068] In summary, the energy consumption optimization control method provided in the embodiment of the present application increases the recognition of the vehicle gear state through the software algorithm, determines whether the vehicle's motion mode is in dynamic mode or static mode according to the gear state of the vehicle, and executes the corresponding vehicle static energy consumption optimization strategy or vehicle dynamic energy consumption optimization strategy respectively. For example, in the static mode, by identifying whether there is an active heating request, and in the dynamic mode, by identifying whether the vehicle has a static trend, the switch device of the motor controller power module is more accurately turned on and off. Only by adjusting the software strategy, without involving the re-selection and matching of the hardware, it will not cause the increase of the hardware cost of the motor controller, and the design of the software strategy is relatively simple, the development cycle is short, and basically no additional software development costs will be generated, so that the efficiency of the motor controller is improved without increasing the cost. At the same time, by reducing the switching loss and conduction loss of the switching device, not only the energy loss in the power conversion process is reduced, which helps to increase the vehicle's cruising range, but also the thermal stress and related thermal fatigue effects of the switching device are reduced, the dependence on the cooling system is reduced, and the service life of the motor controller is extended.
