Example one
Fig. 1 is a flowchart of a method for detecting an effective volume of a urea tank according to an embodiment of the present invention, where the method is applicable to a case where an effective volume of a urea tank is detected, and especially applicable to a case where an effective volume of a urea tank is detected during factory calibration and/or driving, the method may be executed by a device for detecting an effective volume of a urea tank, where the device for detecting an effective volume of a urea tank may be implemented in a form of hardware and/or software, and the device for detecting an effective volume of a urea tank may be configured in an electronic device.
As shown in FIG. 1, the method is applied to an aftertreatment controller of a urea tank, and comprises the following steps:
and S110, after the vehicle is powered on, reading a first effective volume corresponding to the urea tank stored in the target storage.
The aftertreatment controller may refer to a stand-alone scr controller or an engine controller that integrates a scr control function. The target memory may refer to a memory that is electrically erasable and programmable and data is not lost after the controller is powered down. For example, the target memory may be, but is not limited to, a charged Erasable Programmable read only memory (EEPROM). The target storage device does not store a first effective volume corresponding to the urea tank before the vehicle is powered on for the first time; before the vehicle is electrified for the first time, a normal target sensor is installed on the vehicle, and the model of the target sensor is matched with that of the urea tank. The urea tank may refer to a tank for storing urea solution in diesel vehicles such as trucks and buses. The first effective volume may refer to an effective volume of a factory-fitted urea tank of a vehicle stored in the target storage. FIG. 2 shows a schematic of the volume of a urea tank. Referring to FIG. 2, the total volume in the urea tank may include an expansion volume, an active volume, and a dead volume. The effective volume can be the effective volume of the urea tank from the tank opening to the lowest position of the float for storing urea. The expansion volume may be a volume reserved to ensure that the float does not contact the top of the urea tank when the urea level is at a maximum level. The dead volume may be a volume of urea that is not used by the vehicle. The remaining amount of urea stored in the active volume is generally used as a measure of whether the available urea of the vehicle needs to be replenished. The effective volume may be pre-stored in a memory of the target sensor.
Specifically, a starting switch on the vehicle is placed in an opening gear, the vehicle is powered on, and a controller and a sensor in the vehicle are powered on, such as a rear processing controller. After the vehicle is powered on, the post-processing controller can read a first effective volume corresponding to a urea tank stored in a target storage device, so that the characteristic that stored data is not lost when the target storage device is powered off is ensured, the model of a target sensor assembled by the urea tank can be detected after the vehicle is powered on every time, whether the model of the target sensor is matched with the urea tank or not is determined, the calculation of the residual volume of urea in the urea tank can be carried out only under the condition of matching, and the accuracy of the calculation of the residual volume of urea in the urea tank is ensured.
And S120, receiving a second effective volume corresponding to the urea tank sent by a target sensor on the urea tank.
Wherein the target sensor is a sensor that can be used to store an effective volume corresponding to the sensor model. The target sensor can also be used as a sensor for acquiring and transmitting various information of the urea tank. The second effective volume may refer to an effective volume corresponding to a target sensor model stored in a memory of the target sensor.
Specifically, after the vehicle is powered on, the target sensor also realizes the power-on operation, and periodically sends the second effective volume corresponding to the urea tank stored in the storage of the target sensor to the aftertreatment controller, so that when the vehicle is just powered on, the second effective volume corresponding to the model of the target sensor is sent to the aftertreatment controller, and the aftertreatment controller can detect whether the effective volume is effective at the first time after the vehicle is powered on, thereby improving the detection efficiency.
S130, whether the first effective volume is the same as the second effective volume or not is detected.
Specifically, the post-processing controller compares the consistency of the first effective volume read from the target memory and the second effective volume received from the target sensor.
And S140, if the first effective volume is the same as the available effective volume, determining the first effective volume as the available effective volume.
The available effective volume refers to an effective volume which can be used for determining the residual volume of urea in the urea tank of the vehicle.
Specifically, when the first effective volume is detected to be the same as the second effective volume, indicating that the model of the target sensor is matched with the urea tank, the first effective volume is determined to be the available effective volume, and therefore the accurate residual volume of urea in the urea tank can be calculated by using the accurate effective volume.
S150, if the first effective volume is different from the available effective volume, determining that the first effective volume is the unavailable effective volume, generating target sensor abnormal information, and displaying the target sensor abnormal information.
Wherein, the unavailable effective volume refers to the effective volume which can not be used for determining the residual volume of the urea in the urea tank of the vehicle. The target sensor abnormality information may be information reflecting that the model of the target sensor is not matched with the own vehicle urea tank.
Specifically, the first effective volume and the second effective volume are detected to be different, the target sensor model is indicated to be not matched with the urea tank, the first effective volume is determined to be a non-available effective volume, the residual urea volume in the urea tank is not calculated, the abnormal information of the target sensor is generated, and the abnormal information of the target sensor is displayed to remind a driver of timely replacing the target sensor matched with the urea tank, so that the accurate residual urea volume in the urea tank can be calculated by using the wrong effective volume, and the driver is prevented from being misguided.
For example, the "generating the target sensor abnormality information" in S150 may include: determining a target abnormality reason corresponding to the target sensor based on the second effective volume; target sensor abnormality information is generated based on the target abnormality cause.
The target abnormality cause may be a cause of occurrence of abnormality of the target sensor.
Specifically, the aftertreatment controller may determine a target abnormality cause corresponding to the target sensor based on the specific expression of the second effective volume; and generating target sensor abnormal information corresponding to the target abnormal reason based on the target abnormal reason so that the driver can clearly distinguish the abnormality of the target sensor.
According to the technical scheme of the embodiment of the invention, after a vehicle is powered on, a first effective volume corresponding to a urea tank stored in a target storage is read; receiving a second effective volume corresponding to the urea tank, which is sent by a target sensor positioned on the urea tank; detecting whether the first effective volume is the same as the second effective volume; if the first effective volume is the same as the available effective volume, determining the first effective volume as the available effective volume; if the first effective volume is different from the available effective volume, the first effective volume is determined to be the unavailable effective volume, the abnormal information of the target sensor is generated, and the abnormal information of the target sensor is displayed, so that the effective volume of the urea tank configured on the current vehicle is intelligently identified, and the identification efficiency and accuracy are improved.
On the basis of the technical scheme, the method further comprises the following steps: and if the first effective volume corresponding to the urea tank stored in the target storage is not read, storing the received second effective volume corresponding to the urea tank into the target storage as the first effective volume, and determining the stored first effective volume as the available effective volume.
Due to the diversification of the types of target sensors and the effective volumes of the urea tanks, the target storage device can cause the aftertreatment controller of the same engine to be provided with a plurality of types of target sensors and urea tanks with different effective volumes. The target sensors may include urea temperature sensors, urea level sensors, urea quality sensors, sensor controllers, and the like. The urea level sensors of different models, which are used for collecting the percentage of urea level, cannot be used universally.
Specifically, when the vehicle is powered on for the first time, such as offline calibration before leaving a factory, the first effective volume is not stored in the target memory. At this time, the aftertreatment controller cannot read the first effective volume corresponding to the urea tank stored in the target memory. The received second effective volume corresponding to the urea tank is required to be stored to the target storage as the first effective volume, and the stored first effective volume is determined to be the available effective volume, so that the efficiency of identifying and calibrating the effective volume of the vehicle urea tank is improved.
On the basis of the above technical solution, the "determining the target abnormality cause corresponding to the target sensor based on the second effective volume" may include: if the second effective volume is a numerical result, determining that the target abnormality reason corresponding to the target sensor is that the model of the target sensor is not matched with that of the urea tank; and if the second effective volume is a non-numerical result, determining that the target sensor has a fault as a target abnormal reason corresponding to the target sensor.
Wherein a numerical result may refer to an effective volume being a numerical result. The non-numeric result may refer to the valid volume as missing, alphabetical, or special character, wherein missing may refer to the non-numeric result as an empty result.
Specifically, if the second effective volume is a numerical result, for example, 20, indicates that the model of the target sensor is adapted to a 20L urea tank, and the second effective volume is different from the effective volume of the urea tank currently assembled on the vehicle, it is determined that the target abnormality cause corresponding to the target sensor is that the model of the target sensor is not matched with the urea tank; if the second effective volume is a non-numerical result, the fact that the number of the urea tanks which are matched with the target sensor is increased cannot be determined in the CAN message transmitted by the target sensor, and the target abnormal reason corresponding to the target sensor is determined to be that the target sensor breaks down, so that a driver CAN be reminded of the specific reason that the target sensor cannot be used for calculating the residual volume of urea in the urea tanks, and the driver CAN replace or maintain the target sensor conveniently.
Example two
Fig. 3 is a flowchart of a method for detecting an effective volume of a urea tank according to a second embodiment of the present invention, and this embodiment describes in detail a process of calculating a remaining volume of urea in the urea tank based on the second embodiment. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. As shown in fig. 3, the method includes:
and S210, after the vehicle is powered on, reading a first effective volume corresponding to the urea tank stored in the target storage.
And S220, receiving a second effective volume corresponding to the urea tank and the current urea liquid level percentage sent by a target sensor on the urea tank.
Wherein, the urea level percentage may refer to the level percentage of urea in the urea tank. The urea level percentage may be determined by a urea level sensor measurement. The urea level sensors of different models, which are used for collecting the percentage of urea level, cannot be used universally. The current urea level percentage may refer to the percentage of the level of urea in the urea tank at the current time.
Specifically, after the vehicle is powered on, the target sensor is also powered on, and a urea liquid level sensor in the target sensor is also powered on. The target sensor can periodically send the second effective volume and the current urea liquid level percentage corresponding to the urea tank stored in the storage of the target sensor to the aftertreatment controller, so that when the vehicle is just powered on, the second effective volume and the current urea liquid level percentage corresponding to the model of the target sensor are sent to the aftertreatment controller, the aftertreatment controller can detect whether the effective volume is effective or not at the first time after the vehicle is powered on, the initial urea liquid level percentage of the vehicle is determined, and the detection efficiency is further improved.
The target sensor may include a urea temperature sensor, a urea quality sensor, and the like. Wherein, urea temperature sensor can be used for acquireing the urea temperature in the urea jar. A urea quality sensor may be used to obtain the urea concentration in the urea tank.
And S230, detecting whether the first effective volume is the same as the second effective volume.
And S240, if the first effective volume is the same, determining the first effective volume as the available effective volume.
And S250, multiplying the first effective volume by the current urea liquid level percentage to obtain the current residual urea volume.
Wherein, the current urea remaining volume may refer to the volume of urea remaining in the urea tank at the current moment.
Specifically, after obtaining the accurate effective volume of the vehicle urea tank and the accurate current urea level percentage, the first effective volume and the current urea level percentage may be multiplied to obtain the current urea remaining volume. By means of this calculation it is also possible to determine the urea consumption according to the customer demand. For example, the urea residual volume at the initial time and the urea residual volume at the end time of the preset time period are subtracted to determine the urea consumption in the preset time period.
And S260, if the first effective volume is different from the available effective volume, determining that the first effective volume is the unavailable effective volume, generating abnormal information of the target sensor, and displaying the abnormal information of the target sensor.
Specifically, if the difference is not the same, the current residual urea volume is not calculated, the first effective volume is determined to be the unavailable effective volume, the target sensor abnormality information is generated, and the target sensor abnormality information is displayed. Thereby avoiding using an inaccurate first effective volume and an inaccurate current urea level percentage, determining an inaccurate current urea residual volume and avoiding misleading a driver.
According to the technical scheme of the embodiment of the invention, whether the first effective volume is the same as the second effective volume is detected by using the received second effective volume corresponding to the urea tank and the current urea liquid level percentage sent by the target sensor positioned on the urea tank; if the first effective volume and the current urea liquid level percentage are the same, the current urea residual volume can be obtained by multiplying the first effective volume and the current urea liquid level percentage, and therefore the calculation accuracy of the urea residual volume is guaranteed. The aftertreatment controller can detect whether the effective volume is effective or not at the first time after the vehicle is powered on, and determine the initial urea liquid level percentage of the vehicle, so that the detection efficiency is further improved.
The following is an embodiment of the device for detecting an effective volume of a urea tank according to an embodiment of the present invention, which belongs to the same inventive concept as the method for detecting an effective volume of a urea tank according to the above embodiments, and reference may be made to the above embodiment of the method for detecting an effective volume of a urea tank for details that are not described in detail in the embodiment of the device for detecting an effective volume of a urea tank.
