The explanation is made for the terms used in this application:

MAP MAPs refer to motor efficiency MAPs, MAP MAPs corresponding to different voltages are different, MAP MAPs corresponding to vehicles of different models are also different, and MAP MAPs corresponding to each voltage of the vehicle model are stored in the MCU in advance for retrieval and verification.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.
Based on the above-described problems, the motor operation control method provided in the present application is applied to a vehicle controller, as shown in fig. 1, and includes:
step 101, determining a motor control parameter based on the travel request.
In particular, the travel request includes: an accelerator pedal signal (for example, an accelerator pedal opening or an accelerator lever opening provided on a vehicle suitable for a disabled person with legs) and/or an accelerator pedal response signal, and then a motor control parameter (for example, motor torque and motor rotation speed, or at least one of an operating power, an operating current, and an operating voltage of the motor) is determined based on the vehicle speed signal acquired at the corresponding time.
In order to avoid that when the distance between the driver and the object in front is small, the driver suddenly steps on the accelerator pedal, after the speed of the vehicle is rapidly increased, the vehicle is likely to collide with the object in front, and at the moment, the driver suddenly steps on the brake pedal to decelerate, so that the brake consumption is too high.
In some embodiments, a distance sensor (e.g., a front radar, a front infrared ranging module) is disposed in front of the vehicle, and is capable of detecting a distance between the vehicle and a front object (e.g., a front vehicle, a front obstacle, or a front roadside) in real time, and after receiving a driving request, the vehicle controller combines the detected distance with the driving request to determine a corresponding motor control parameter.
When the vehicle is in specific implementation, corresponding vehicle distance thresholds are correspondingly set under different vehicle speeds, if the real-time vehicle distance between the vehicle and a front object detected in real time is smaller than or equal to the vehicle distance thresholds, motor control parameters determined according to a running request can be reduced, vehicle acceleration is further reduced, collision danger is avoided, and subsequent braking energy consumption can be reduced. The reduction of the corresponding motor control parameter is proportional to the difference between the real-time vehicle distance and the vehicle distance threshold value.
In addition, if the real-time vehicle distance is greater than the vehicle distance threshold value, the motor control parameters determined according to the driving request are not adjusted.
Step 102, the motor control parameters are sent to a motor controller so that the motor controller can operate according to the motor control parameters, and efficiency verification is carried out on actual motor operation parameters to determine an efficiency verification result.
In particular, the vehicle controller is connected to the motor controller via wires (e.g., CAN, controller Area Network, controller area network bus). The whole vehicle controller can send the determined motor control parameters to the motor controller through wires, and the motor controller can control the motor to run according to the motor control parameters.
The motor controller may pre-store data content for efficiency verification, which may be stored in the form of a table or a graphic. The data content comprises efficiency related data corresponding to various motor operation parameters. In this embodiment, a motor efficiency MAP (MAP) is stored in the motor controller, as shown in fig. 3B-1 to 3B-3, in which the horizontal axis represents the rotation speed (S), the vertical axis represents the torque value (T), and the corresponding efficiency value ranges are marked correspondingly, where the higher the efficiency is, the higher the efficiency value is, the optimal motor control parameter and the corresponding motor energy consumption level value can be determined according to the efficiency value.
In the process of controlling the motor to operate, the motor controller can acquire current actual motor operation parameters of the motor, compares and checks the actual motor operation parameters with prestored data content for efficiency check, determines data matched with the actual motor operation parameters in the data content, and determines an efficiency check result according to the matched data. Wherein the efficiency-check result represents an efficiency state determined based on the matched data.
Step 103, receiving the efficiency verification result sent by the motor controller, determining a motor adjustment parameter based on the efficiency verification result, and sending the motor adjustment parameter to the motor controller for the motor controller to perform operation adjustment based on the motor adjustment parameter.
In specific implementation, the whole vehicle controller can receive the efficiency verification result sent by the motor controller, so that the motor control parameters sent to the motor controller last time are adjusted according to the efficiency verification result, and motor adjustment parameters are generated. The motor adjusting parameter is used for adjusting the actual motor operating parameter, so that the motor can be in a more efficient operating state after adjustment, and the motor adjusting parameter comprises: the first predetermined value is increased or the second predetermined value is decreased, or the motor control parameter 0 is not adjusted.
Therefore, after the motor controller receives the motor adjustment parameters, the motor controller can adjust the motor adjustment parameters on the basis of the current actual motor operation parameters, and the motor controller can control the motor to be in a relatively efficient operation state all the time.
Through the scheme, the whole vehicle controller determines the motor control parameters according to the running request, then sends the motor control parameters to the motor controller, and then controls the operation of the motor controller, the motor controller can perform efficiency verification on the actual motor operation parameters during operation, and sends the efficiency verification result to the whole vehicle controller, so that the whole vehicle controller can generate motor adjustment parameters with higher efficiency based on the efficiency verification result, the motor control parameters can be corrected, after the motor adjustment parameters are sent to the motor controller, the operation correction of the motor controller can be realized, the motor controller can operate in a relatively efficient state, the motor operation efficiency is further improved, the energy consumption condition of the motor is effectively reduced, the energy utilization rate of the vehicle is effectively improved, the number of times of vehicle charging can be further reduced, and the vehicle cost is reduced.
In some embodiments, the efficiency-checking result includes: optimal motor control parameters;
when the method is implemented, the motor controller determines the highest-efficiency operation parameter of the motor corresponding to the actual operation parameter in the prestored data content according to the actual motor operation parameter when performing efficiency verification, and sends the highest-efficiency operation parameter of the motor corresponding to the actual operation parameter to the whole vehicle controller as the optimal motor control parameter.
Wherein, the optimal motor control parameters include: at least one of an optimal torque value, an optimal rotational speed value, an optimal current value, and an optimal voltage value. Preferably an optimal torque value and an optimal rotational speed value.
Thus, the determining motor adjustment parameters based on the efficiency check result in step 103 includes:
step 1031, determining an optimal motor control parameter from the efficiency verification result, and retrieving an actual motor control parameter from the motor controller.
Step 1032, determining the motor adjustment parameter according to the deviation between the actual motor operation parameter and the optimal motor control parameter.
In specific implementation, after receiving the optimal motor control parameter, the whole vehicle controller calculates a deviation amount (wherein the deviation amount may be an increase amount or a decrease amount) between the actual motor operation parameter and the optimal motor control parameter so that the current actual motor operation parameter can catch up with the optimal motor control parameter, and then uses the deviation amount as a motor adjustment parameter.
For example, the deviation amount may be a rotational speed deviation amount (actual rotational speed value in the actual motor operation parameter, difference from the optimum rotational speed value) and/or a torque deviation amount (torque rotational speed value in the actual motor operation parameter, difference from the optimum torque value), and then the rotational speed deviation amount and/or the torque deviation amount are taken as the motor adjustment parameter.
Through the scheme, the whole vehicle controller can determine the most suitable motor adjustment parameters based on the optimal motor control parameters, and output correction of the motor controller to the whole vehicle controller is realized; the whole vehicle controller sends the motor adjustment parameters to the motor controller, so that the motor controller adjusts the actual operation parameters according to the motor adjustment parameters, and the correction of the whole vehicle controller to the motor controller is realized, thus the bidirectional verification of the whole vehicle controller and the motor controller can be completed, the motor can be in an efficient operation state, and the energy consumption is further saved.
In some embodiments, the efficiency-checking result includes: and the motor energy consumption state is an energy consumption degree value obtained by comparing the efficiency of the motor controller based on the actual motor operation parameters.
In specific implementation, the motor controller determines an energy consumption degree value according to the comparison of the actual motor operation parameters and the stored data content, wherein the energy consumption degree value represents the condition of motor energy consumption, and the higher the energy consumption degree value is, the higher the motor energy consumption is. From the energy consumption level value, an energy consumption level (e.g., classified as high energy consumption, medium energy consumption, low energy consumption, or as highest energy consumption, high energy consumption, medium energy consumption, low energy consumption, lowest energy consumption) may be determined, and the energy consumption level is included in the efficiency check result as the energy consumption state. The dividing number of the energy consumption levels can be determined by dividing according to actual needs.
The motor controller compares the actual motor operation parameters with the stored data content to obtain optimal motor control parameters and/or energy consumption states, preferably optimal motor control parameters and motor energy consumption states, in the verification process.
After receiving the efficiency check result sent by the motor controller in step 103, the method further includes:
and A1, determining an energy consumption state from the efficiency verification result, and performing data conversion on the energy consumption state of the motor to obtain energy consumption state display data.
And step A2, the motor energy state display data are sent to a display device for display.
When the method is implemented, after the motor controller obtains the motor energy consumption state, the motor energy consumption state is sent to the whole vehicle controller, so that the whole vehicle controller can convert the motor energy consumption state into display data which can be displayed by the display equipment, and the display data is sent to the display equipment for display.
Wherein the display device comprises at least one of: the device comprises a central control display screen, a vehicle instrument display screen and a head-up display screen.
Through the scheme, the motor energy consumption state determined by the motor controller can be displayed through the whole vehicle controller, so that a driver can acquire the current energy consumption situation, and then the driver can operate and control according to the energy consumption situation. For example, if the motor energy consumption state displayed by the display device is a high energy consumption state, the driver is prompted, and the driver can adjust the operation (e.g., reduce the stepping amplitude of the accelerator pedal) according to the corresponding prompt, so that the driver is prompted to keep good driving operation, avoiding always the high energy consumption state, so that the energy consumption of the vehicle can be effectively reduced, the cost of using the vehicle is reduced, and frequent energy charging (e.g., at least one of charging, refueling, hydrogen charging and natural gas charging) is not required.
Another embodiment of the present application proposes a motor operation control method applied to a motor controller, as shown in fig. 2, including:
step 201, receiving a motor control parameter sent by a vehicle controller, and performing operation control based on the motor control parameter.
In specific implementation, the process of determining the motor control parameter by the vehicle controller may refer to step 101 and the specific development details in the above embodiment, which are not described herein.
After the motor controller receives the motor control parameters sent by the whole vehicle controller, the motor controller can control the motor to run according to the motor control parameters.
Step 202, obtaining an actual motor operation parameter, and performing efficiency verification on the actual motor operation parameter to obtain an efficiency verification result.
In particular, the motor controller stores data content for efficiency verification in advance, and the data content can be stored in a form of a table or a graph. The data content comprises efficiency related data corresponding to various motor operation parameters.
And in the process of controlling the motor to operate, the motor controller acquires actual motor operation parameters of the motor after a preset time interval, compares the actual motor operation parameters with stored content of efficiency verification, and determines efficiency-related data corresponding to the actual motor operation parameters.
The corresponding obtained efficiency check result comprises: the optimal motor control parameter corresponding to the optimal efficiency or the numerical condition of the actual motor operation parameter, and the determined motor energy consumption state, wherein the motor energy consumption state comprises a motor energy consumption degree value, the energy consumption degree value can be an energy consumption level (for example, divided into high energy consumption, medium energy consumption and low energy consumption, or divided into highest energy consumption, high energy consumption, medium energy consumption, low energy consumption and lowest energy consumption), and the dividing number of the energy consumption levels can be determined according to actual requirements.
And step 203, sending the efficiency verification result to the whole vehicle controller so that the whole vehicle controller can determine motor adjustment parameters according to the efficiency verification result.

And 204, receiving motor adjustment parameters sent by the whole vehicle controller, and performing operation adjustment based on the motor adjustment parameters.
When the motor control system is in specific implementation, after the motor controller receives the motor adjustment parameters, the motor controller can adjust the motor adjustment parameters based on the current actual motor operation parameters, so that the motor controller can control the motor to be in a relatively efficient operation state all the time.
Through the scheme, the whole vehicle controller determines the most suitable motor adjustment parameters based on the efficiency verification result, and output correction of the motor controller to the whole vehicle controller is realized; the whole vehicle controller sends the motor adjustment parameters to the motor controller, so that the motor controller adjusts the actual operation parameters according to the motor adjustment parameters, and the correction of the whole vehicle controller to the motor controller is realized, thus the bidirectional verification of the whole vehicle controller and the motor controller can be completed, the motor can be in an efficient operation state, and the energy consumption is further saved.

Ensuring that the motor always operates in a relatively efficient range. The process of the above embodiment is repeated until the running request received by the whole vehicle controller changes (for example, the opening degree of the accelerator pedal is changed, the road condition is changed or the brake pedal is depressed), and a new running request is responded.
Through the scheme, the corresponding target efficiency map is selected for verification according to the actual motor operation parameters, so that the verification process is simple and quick, the efficiency verification result can be obtained quickly, the speed of the bidirectional verification of the motor controller and the whole vehicle controller is high, and the efficiency of double-effect verification is improved.
