Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The vehicle water pump fault processing method provided by the embodiment of the 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 outlet of a water tank 108. The control device 100 controls the operation of the water pump 106 by sending a command to the water pump 106. Wherein, the control device can adopt a single control device or a plurality of control devices. Further, the Control device 100 may include a processor 102 and a water pump controller 104, the water pump controller 104 may connect the processor 102 and the water pump 106, the processor 102 may employ an ECU (Electronic Control Unit), an MCU (Micro Control Unit), and the like, and the water pump 106 includes a motor and an impeller driven by the motor. Taking the ECU as an example of the processor 102, the ECU is connected to the water pump controller 104 through a power line KL30 and a ground line KL31, and the ECU further sends instructions such as start, stop, sleep, wake up and the like to the water pump controller 104 in a LIN (Local Interconnect Network)/PWM (Pulse Width Modulation) manner, and controls the water pump 106 to operate through the water pump controller 104. When a water pump of a vehicle is in a running state, the water pump controller 104 detects running state parameters of the water pump 106 and sends the running state parameters to the ECU, and when the running state parameters meet preset locked-rotor judgment conditions, the ECU controls the water pump 106 to carry out repeated starting control according to preset time intervals through the water pump controller 104, so that the locked-rotor of the water pump 106 is eliminated. If the water pump is blocked by the foreign matters in the operation process, the foreign matters can be removed in a mode of stopping and restarting the water pump through the locked-rotor protection and the rejection function, and the water pump and other vehicle parts are prevented from being damaged.
In one embodiment, as shown in fig. 2, a vehicle water pump fault handling method is provided, which is applied to a control device, and particularly, if the control device comprises an ECU and a water pump controller, the method can be applied to the ECU. The method comprises the following steps:
step S100: and when the water pump of the vehicle is in the running state, obtaining the running state parameters of the water pump.
Specifically, the operation and the stop of the water pump can be controlled by the control equipment, and the operation state parameters of the water pump are collected when the water pump is in an operation state. And the control equipment detects the running state parameters of the water pump in real time when controlling the water pump to run. It will be appreciated that the type of operating condition parameter is not exclusive and may be the speed of the water pump or other parameter. In one embodiment, the operating condition parameters of the water pump include current and/or speed. Taking the operation state parameters including current and rotation speed as an example, when the water pump is in an operation state, the control device detects the current of a motor of the water pump in real time, and calculates the rotation speed of the water pump according to the detected current, for example, the rotation speed of the water pump is calculated by combining the period of the detected sine wave current and a corresponding formula, and the obtained current and rotation speed are used as the control device to analyze whether the water pump is locked. In other embodiments, the rotation speed of the water pump can be detected by a sensor and fed back to the control device.
Step S200: and if the running state parameters meet the preset locked-rotor judging conditions, repeatedly starting and controlling the water pump according to a preset time interval so as to eliminate the locked-rotor of the water pump.
Correspondingly, after the control equipment acquires the running state parameters, the running state parameters are compared with preset locked-rotor judging conditions, when the running state parameters meet the preset locked-rotor judging conditions, the control equipment judges that the water pump is locked-rotor, and the water pump is repeatedly started and controlled according to a preset time interval, so that the locked-rotor of the water pump is eliminated. Wherein, controlgear is judging the water pump and taking place the stall back, can be directly carry out the restart control to the water pump and eliminate the stall, also can detect the running state parameter of water pump again, confirms the water pump many times and takes place the stall back, carries out the restart control to the water pump and eliminates the stall, avoids appearing the erroneous judgement. It is understood that the specific content of the locked-rotor determining condition may be different according to the type of the operating state parameter. Also taking the example that the operating state parameters include current and rotation speed, the locked-rotor determination condition may include that the rotation speed of the water pump is less than a set rotation speed threshold, and/or the current of the water pump is greater than a set current threshold. The specific values of the set rotating speed threshold and the set current threshold are not unique and can be set according to actual needs. Furthermore, the value of the preset time interval for repeatedly starting the water pump and the repeated starting times of the water pump are not unique, and can be selected according to actual conditions. The predetermined time interval between each repeated start may be the same or different, i.e., the predetermined time interval may have only one value or a plurality of values.
According to the vehicle water pump fault processing method, the running state parameters of the water pump are monitored, when the running state parameters meet the preset locked-rotor judgment condition, the water pump is repeatedly started and controlled according to the preset time interval, the water pump fault is timely detected and processed, the water pump and other parts can be prevented from being damaged, and the service life of a vehicle is prolonged.
In one embodiment, as shown in FIG. 3, step S200 includes step S210 and step S220.
Step S210: and if the running state parameters meet the preset locked-rotor judgment conditions, controlling the water pump to stop running for a set time interval and then starting. The value of the set time interval is not unique, and the value of the set time interval and the value of the preset time interval can be the same or different. When the control equipment judges that the running state parameters meet the preset locked rotor judgment condition, the control equipment firstly controls the water pump to stop running and then starts the water pump after the water pump stops running and reaches the set time interval.
Step S220: and if the running state parameters of the water pump after the water pump is stopped and restarted are detected to meet the preset locked-rotor judging conditions for the first preset times, repeatedly starting and controlling the water pump according to the preset time interval so as to eliminate the locked-rotor of the water pump.
It is understood that the specific value of the first preset number can also be set according to the actual requirement, and for example, the number can be 2 or more than 3. After the control equipment controls the water pump to stop running for a set time interval and then starts, continuously acquiring running state parameters of the water pump and judging whether the running state parameters meet the locked rotor judgment condition, and if not, the water pump can continue to run normally; if the running state parameters of the water pump are still detected to meet the locked-rotor judging condition, the water pump is stopped running again for a set time interval, then the water pump is started and the running state parameters of the water pump are detected, the running state parameters of the water pump are detected to meet the locked-rotor judging condition after the water pump is stopped and restarted for a first preset number of times (for example, 4 times), the rejection function is started, and the water pump is controlled to be started repeatedly according to the preset time interval so that the locked-rotor of the water pump is eliminated. The set time interval for stopping and restarting the water pump each time can be the same or different, namely, the set time interval can be only one value or a plurality of values.
In this embodiment, when detecting that the operating state parameters of the water pump after stopping and restarting all meet the preset locked rotor determination conditions for a plurality of times, the control of repeatedly starting the water pump is performed according to the preset time interval, so that the locked rotor of the water pump is eliminated, and the occurrence of false detection is avoided. In addition, when the running state parameter of the water pump meets the preset locked-rotor judgment condition, the method can further comprise the step of setting a locked-rotor mark. Specifically, if the running state parameters of the water pump after the water pump is stopped and restarted are detected to meet the preset locked-rotor judgment conditions for the first preset times, the control device further sets an over-current/locked-rotor fault bit, and the over-current/locked-rotor fault bit indicates that the water pump has a fault.
In one embodiment, as shown in fig. 4, the repeated start control of the water pump at preset time intervals in step S200 or step S220 to remove the locked rotor of the water pump includes step S230 and step S240.
Step S230: and controlling the water pump to be started repeatedly for a second preset time according to the preset time interval, and then acquiring the running state parameters of the water pump 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 obtains the running state parameters of the water pump again after the restart for the second preset number of times is completed. The specific value of the second preset number of times can also be set according to actual needs, for example, the specific value can also be 2 times or more than 3 times.
Step S240: and if the operation state parameters obtained again still meet the preset locked-rotor judgment conditions, controlling the water pump to be started and stopped repeatedly for a third preset number of times according to the preset low rotating speed value, and releasing an impeller of the water pump to enable the water pump to eliminate locked-rotor.
The values of the preset low rotating speed value and the third preset times are not unique, the preset low rotating speed value can be set to be a lower speed value lower than the rotating speed of the water pump in normal operation, and the third preset times can be 2 times or more than 3 times. After the water pump is controlled to restart for the second preset number of times according to the preset time interval, if the operation state parameters obtained again still meet the preset locked-rotor judgment conditions, the locked-rotor fault is not eliminated, the control device controls the water pump to be repeatedly started and stopped for the third preset number of times according to the preset low rotating speed value, and the impeller of the water pump is released by reducing the rotating speed of the water pump and then repeatedly starting and stopping for multiple times, so that the locked-rotor of the water pump is eliminated. The impeller of the water pump is released, namely the water pump is switched on and off by controlling the low-speed repeated start and stop of the water pump, so that the blockage or winding of foreign matters in a waterway on the impeller of the water pump is eliminated, and the impeller is prevented from being clamped.
Further, in one embodiment, after step S240, the method further comprises: and if the locked rotor of the water pump is detected, controlling the water pump to stop. After the control device controls the water pump to repeatedly start and stop for a plurality of times at a lower speed, if the running state parameters of the water pump are detected again, the running state parameters of the water pump still accord with the locked rotor judgment condition, namely, the impeller of the water pump is not successfully released, the locked rotor fault of the water pump is not eliminated, the control device controls the water pump to be completely stopped at the moment, and the water pump is prevented from running and being damaged under the condition of the locked rotor fault. In addition, if the water pump is controlled to be started and stopped repeatedly at a low speed for multiple times and then the water pump impeller is detected to be successfully released, the control equipment eliminates the locked rotor mark and enters a normal operation mode, and the water pump continues to operate normally.
In order to better understand the method for handling the water pump failure of the vehicle, the following detailed explanation is provided with reference to specific embodiments.
In the vehicle use, can lead to the water route foreign matter to block up the water pump because of various factors, the water pump still continuous operation can lead to the water pump to damage this moment, and the vehicle does not have the protect function to the water pump at present. Based on this, the application provides a vehicle water pump stalling and rejection processing method, increases anti-stalling and rejection function, prevents to damage spare parts such as water pump. Judging whether the water pump is locked up through the rotating speed and the current, controlling the water pump to release the impeller through the rejection function after the locked up is judged, clearing the locked up mark to enter a normal operation mode when the rejection process meets the recovery condition, and completely stopping the machine if the rejection process is finished and faults are still reported.
As shown in fig. 1, the vehicle ECU sends instructions such as start, stop and sleep, wake up to the water pump controller through LIN/PWM to control the operation of the water pump. When the water pump is in an operating state, the water pump controller detects the current of a motor of the water pump in real time, and the rotating speed of the water pump is calculated according to the detected current. And then, the water pump controller sends the obtained current and the obtained rotating speed to the ECU so that the ECU can analyze whether the water pump is locked or not. If the water pump is blocked by the foreign matters in the operation process, the foreign matters are removed in the mode of stopping and restarting the water pump through the locked-rotor protection and rejection functions, and the water pump and other automobile parts are prevented from being damaged. As shown in fig. 5 and 6, the principle of the locked rotor and the rejection of the water pump is as follows:
and (3) locked rotor judgment: when the water pump is in an operating state, the rotating speed and the current of the water pump are detected and whether the water pump is locked or not is analyzed. 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 locked rotor occurs. And when the locked rotor is judged not to occur, the water pump normally operates, and the rotating speed and the current of the water pump are continuously detected. When the locked rotor is judged to occur, the water pump is started after the first time of operation stop, the set interval time is t1, then whether the locked rotor still occurs is detected for 2 nd and 3 rd times, namely whether the rotating speed is smaller than the set rotating speed threshold Speedth or not is continuously judged, the current exceeds the set current threshold Ith, and the set interval time for the water pump to stop is t2 and t3 respectively. The detection is repeated until the rotating speed is judged to be less than the set rotating speed threshold Speedth and the current exceeds the set current threshold Ith for a first preset time (such as 4 th time), and the rejection function is started. After entering the rejection function, the setting of Bit 'unstall function' flag Bit 'locked-rotor clearing' is also carried out.
Rejection function: restarting for a second preset number of times at certain preset time intervals, such as t4, t5, …, tn (n is a natural number), and if the locked rotor is eliminated, the water pump enters a normal operation mode. And if the locked rotor still exists, controlling the water pump to repeatedly start and stop at a lower rotating speed for a third preset number of times according to a preset low rotating speed threshold value so as to release the impeller, if the locked rotor is still detected, completely stopping the water pump, and setting the Bit over current flag Bit to be over-current. When the impeller is detected to be successfully released and the water pump is judged not to be locked, the locked-rotor mark is removed (including the settings of removing Bit 'under function' flag Bit 'and removing locked-rotor' and Bit 'over current' flag Bit 'and overcurrent') and the normal operation mode is entered. In addition, after the water pump is completely stopped, zero clearing operation can be carried out when the water pump is started next time, and the locked rotor mark is cleared to enter a normal operation mode. This application is when having the foreign matter in the water route, increases the function of anti-lock commentaries on classics and rejection, realizes the function of water pump shutdown protection and getting rid of the foreign matter, prevents to damage spare parts such as vehicle water pump, promotes the vehicle quality, has reduceed the use risk, extension vehicle life.
