Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

The vehicle water pump fault handling method provided in the embodiment of the present application can be applied to the application environment shown in FIG. 1 . The control device 100 is connected to a water pump 106 , and the water pump 106 is connected to the water inlet and the water outlet of the water tank 108 . The control device 100 controls the water pump 106 to work by sending an instruction to the water pump 106 . The control device may use a single control device, or may use multiple control devices. Further, the control device 100 may include a processor 102 and a water pump controller 104, the water pump controller 104 is connected to the processor 102 and the water pump 106, and the processor 102 may adopt ECU (Electronic Control Unit, electronic control unit), MCU (Micro Control Unit) , micro-control unit) and other devices, the water pump 106 includes a motor and an impeller driven by the motor. Taking the processor 102 as an ECU as an example, the ECU is connected to the water pump controller 104 through the power line KL30 and the ground line KL31, and the ECU also uses a LIN (Local Interconnect Network)/PWM (Pulse Width Modulation, pulse width modulation) method. Send start, stop, sleep, wake-up and other commands to the water pump controller 104 , and the water pump 106 is controlled to run by the water pump controller 104 . When the water pump of the vehicle is in the running state, the water pump controller 104 detects the running state parameters of the water pump 106 and sends them to the ECU. When the running state parameters meet the preset stall determination conditions, the ECU controls the water pump 106 through the water pump controller 104 according to the preset conditions. The time interval is set for repeated start control, so that the pump 106 can eliminate the stall. If the water pump is stuck by foreign objects during operation, the lock-rotor protection and exclusion functions can be used to realize the shutdown and restart of the water pump to remove foreign objects and prevent damage to vehicle parts such as the water pump.

In one embodiment, as shown in FIG. 2 , a method for handling a fault of a water pump of a vehicle is provided, which is applied to a control device. If the control device includes an ECU and a water pump controller, the method can be specifically applied to the ECU. The method includes:

Step S100: When the water pump of the vehicle is in the running state, obtain the running state parameters of the water pump.

Specifically, the running and stopping of the water pump can be controlled by the control device, and when the water pump is in the running state, the running state parameters of the water pump can be collected. When the control equipment controls the operation of the water pump, it detects the running state parameters of the water pump in real time. It can be understood that the types of operating state parameters are not unique, and may be the speed of the pump or other parameters. In one embodiment, the operating state parameters of the water pump include current and/or rotational speed. Taking the running state parameters including current and rotational speed as an example, when the water pump is in the running state, the control device detects the motor current of the water pump in real time, and calculates the rotational speed of the water pump according to the detected current. The formula calculates the speed of the pump, and the obtained current and speed are used as the control device to analyze whether the pump is blocked. In other embodiments, the rotational speed of the water pump may also be detected by a sensor and fed back to the control device.

Step S200 : if the running state parameters meet the preset locked-rotor judging conditions, the pump is repeatedly started and controlled at preset time intervals, so as to eliminate the locked-rotor of the pump.

Correspondingly, after obtaining the running state parameters, the control device compares the running state parameters with the preset stall judgment conditions, and when the running state parameters meet the preset stall judgment conditions, the control device determines that the pump is blocked. , control the pump repeatedly according to the preset time interval, so as to eliminate the locked rotor of the pump. Among them, after the control device determines that the pump is locked, it can directly control the pump to repeatedly start the pump to eliminate the locked rotor, or it can check the operating state parameters of the pump again. Start control eliminates stall and avoids misjudgment. It can be understood that, according to the different types of operating state parameters, the specific content of the stall judgment conditions will also be correspondingly different. Also taking the running state parameters including current and rotational speed as an example, the stall determination condition may include that the rotational speed of the water pump is less than the set rotational speed threshold, and/or the current of the water pump is greater than the set current threshold. The specific values of the set rotational speed threshold and the set current threshold are not unique, and can be set according to actual needs. Further, the value of the preset time interval for repeatedly starting the water pump and the number of times of repeatedly starting the water pump are not unique, and can be selected according to the actual situation. The preset time interval between each repeated activation may be the same or different, that is, the preset time interval may have only one value, or may have multiple values.

The above vehicle water pump fault handling method, by monitoring the running state parameters of the water pump, and when the running state parameters meet the preset stall judgment conditions, the water pump is repeatedly started and controlled at preset time intervals, so as to detect the water pump fault in time and deal with it. , It can prevent damage to parts such as water pumps and prolong the service life of the vehicle.

In one embodiment, as shown in FIG. 3 , step S200 includes step S210 and step S220.

Step S210 : if the running state parameters meet the preset stall judgment conditions, the water pump is controlled to stop running for a set time interval before starting. The value of the set time interval is not unique, and the value of the set time interval and the preset time interval may be the same or different. When the control device determines that the running state parameters meet the preset stall determination conditions, it first controls the water pump to stop running, and then starts the water pump after the water pump stops running for a set time interval.

Step S220: If it is detected for the first preset number of consecutive times that the running state parameters of the pump after stopping and restarting all meet the preset stall judgment conditions, the pump is repeatedly started at preset time intervals to eliminate the stall.

It can be understood that the specific value of the first preset number of times can also be set according to actual needs, for example, it can be 2 times or more than 3 times. The control device controls the pump to stop running after the set time interval and restarts, and continues to obtain the running state parameters of the pump and judges whether it meets the conditions of the stall judgment. If not, the pump can continue to run normally; if the running state parameters of the pump are still detected If the conditions for the judgment of stall are met, stop the pump again for the set time interval, then start the pump and check the running state parameters of the pump, until the first preset number of consecutive times (for example, 4 consecutive times) stop and restart the pump, all detections are detected. If the running state parameters of the water pump meet the conditions for determining the stalled rotor, the exclusion function will be entered, and the pump will be repeatedly started and controlled at preset time intervals to eliminate the stalled rotor. The set time interval for restarting the water pump each time may be the same or different, that is, the set time interval may be only one value or may have multiple values.

In this embodiment, when it is continuously detected that the running state parameters of the water pump after stopping and restarting all meet the preset stall judgment conditions, the water pump is repeatedly restarted according to the preset time interval, so that the water pump can eliminate the stalled rotor. , to avoid false detections. In addition, when the running state parameters of the water pump meet the preset stall judgment conditions, the method may further include the step of setting a stall flag. Specifically, if it is detected for the first preset number of consecutive times that the operating state parameters after the pump is stopped and restarted all meet the preset stall judgment conditions, the control device further sets an overcurrent/stalled fault bit, the overcurrent/stalled rotor The fault bit indicates that the pump has failed.

In one embodiment, as shown in FIG. 4 , in step S200 or step S220 , the water pump is controlled to start repeatedly according to preset time intervals, so that the water pump can eliminate the stall, including steps S230 and S240 .

Step S230: After the water pump is controlled to start repeatedly for a second preset number of times according to the preset time interval, the operating state parameters of the water pump are obtained again.

Specifically, the control device controls the water pump to restart for a second preset number of times according to a preset time interval, and re-acquires operating state parameters of the water pump after completing the second preset number of restarts. The specific value of the second preset number of times can also be set according to actual needs, for example, it can also be 2 times or more than 3 times.

Step S240: If the re-acquired operating state parameters still meet the preset stall judgment conditions, control the pump to start and stop the pump repeatedly for a third preset number of times according to the preset low speed value, and release the impeller of the pump to eliminate the stall.

The preset low speed value and the value of the third preset number of times are not unique. The preset low speed value can be set to a lower speed value that is lower than the speed of the pump during normal operation, and the third preset number of times can also be set. 2 or more times. After the water pump is controlled to restart the second preset number of times according to the preset time interval, if the operating state parameters obtained again still meet the preset stall judgment conditions, it means that the stall fault has not been eliminated, and the control device will follow the preset The low speed value controls the pump to start and stop repeatedly for the third preset number of times. By reducing the speed of the pump and then repeating the start and stop several times, the impeller of the pump is released, so that the pump can eliminate the stall. Among them, releasing the impeller of the water pump means that by controlling the pump to repeatedly start and stop at low speed, the water pump is switched on and off to eliminate the blockage or entanglement of the water pump impeller by foreign objects in the waterway, so as to avoid the impeller from being stuck.

In addition, in one embodiment, after step S240, the method further includes: if it is detected that the water pump is still locked, controlling the water pump to stop. After the control equipment controls the pump to start and stop repeatedly at a low speed, if it detects that the running state parameters of the pump still meet the conditions for determining the stalled rotor, that is, the impeller of the pump has not been released successfully, and the stalled rotor fault of the pump has not been eliminated. The equipment controls the water pump to stop completely to avoid damage to the water pump when it runs under the presence of a locked-rotor fault. In addition, if the control pump repeatedly starts and stops at a low speed and detects that the pump impeller is released successfully, the control device will remove the locked-rotor flag and enter the normal operation mode, and the pump will continue to operate normally.

In order to facilitate a better understanding of the above-mentioned vehicle water pump fault handling method, detailed explanations are given below with reference to specific embodiments.

During the use of the vehicle, foreign objects in the waterway will block the water pump due to various factors. At this time, the water pump will continue to run and the water pump will be damaged. At present, the vehicle does not have a protection function for the water pump. Based on this, the present application provides a method for treating a vehicle water pump blocked and excluded, which increases the anti-blocking and exclusion functions, and prevents damage to parts such as a water pump. Determine whether the pump is locked by the speed and current. After determining the locked rotor, control the pump to release the impeller through the exclusion function. During the exclusion process, when the recovery conditions are met, clear the locked rotor flag and enter the normal operation mode. After the exclusion process is completed, the fault is reported completely. downtime.

As shown in Figure 1, the vehicle ECU control unit sends commands such as start, stop, sleep, and wake-up to the water pump controller through LIN/PWM to control the operation of the water pump. When the water pump is running, the water pump controller detects the motor current of the water pump in real time, and calculates the rotational speed of the water pump according to the detected current. Then, the water pump controller sends the obtained current and rotational speed to the ECU control unit for the ECU control unit to analyze whether the water pump is blocked. If the water pump is stuck by foreign objects during operation, the lock-rotor protection and the exclusion function can realize the shutdown and restart of the water pump to remove foreign objects and prevent damage to the water pump and other auto parts. As shown in Fig. 5 and Fig. 6, the principle of locked rotor and rejection of the water pump is as follows:

Stalled rotor determination: When the water pump is running, detect the speed and current of the water pump and analyze whether the water pump is locked. Specifically, if it is detected that the rotation speed of the water pump is less than the set rotation speed threshold Speedth, and the current exceeds the set current threshold Ith, it is determined that a stall occurs. When it is determined that no stall occurs, the water pump runs normally, and continues to detect the speed and current of the water pump. When it is determined that the stall occurs, the pump will start after the first time the pump stops running, and the set interval is t1, and then the second and third times to detect whether stall still occurs, that is, continue to determine whether the speed is less than the set speed threshold Speedth, and the current When the set current threshold value Ith is exceeded, the set interval time for the water pump to stop is t2 and t3 respectively. The detection is repeated until it is determined that the speed is less than the set speed threshold Speedth and the current exceeds the set current threshold Ith after the first preset number of times (eg, the fourth time), and the rejection function is entered. After entering the rejection function, the Bit "unstall funcion" flag bit "clear stall" is also set.

Rejection function: The second preset number of restarts are performed at certain preset time intervals, such as t4, t5, ..., tn (n is a natural number). If the stall is eliminated, the pump will enter the normal operation mode. If it is still determined that there is a stall, the pump will be controlled to start and stop the pump repeatedly at a lower speed for a third preset number of times according to the preset low speed threshold to release the impeller. If the stall is still detected, it will stop completely, and the Bit "over current" flag "Overcurrent" setting. When it is detected that the impeller is released successfully and it is judged that the pump is not stalled, the stall flag will be cleared (including clearing the Bit "unstall funcion" flag "Clear stall" setting and Bit "over current" flag "overcurrent" setting) Enter normal operation mode. In addition, after the pump is completely shut down, the zero-clearing operation can also be performed at the next start-up, and the locked-rotor flag is cleared to enter the normal operation mode. When there are foreign objects in the waterway, the application adds the functions of preventing blocking and removing foreign objects, realizing the functions of water pump shutdown protection and removing foreign objects, preventing damage to parts such as the water pump of the vehicle, improving the quality of the vehicle, reducing the use risk and prolonging the service life of the vehicle. .
