Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. Based on the embodiments of the present application, every other embodiment that a person skilled in the art would obtain without making any inventive effort is within the scope of protection of the present application.
First, application scenarios applicable to the present application will be described. The method and the device can be applied to fault diagnosis of the rotating speed sensor of the hybrid gearbox.
Based on the above, the embodiment of the application provides a method for diagnosing a rotation speed sensor fault, an electronic device and a storage medium.
Example 1
The hybrid gearbox is provided with a first rotational speed sensor and a second rotational speed sensor, wherein the first rotational speed sensor is arranged on an input shaft of the motor, the second rotational speed sensor is arranged on a target driving shaft, and the target driving shaft is one of the input shaft, the middle shaft and an output shaft of the motor.
In this embodiment, a dual speed sensor is used, as compared to a conventional gearbox in which only a single speed sensor is provided. Because of the different drive modes between a hybrid gearbox and a conventional gearbox, one rotational speed sensor is selected to be arranged on the motor input shaft, and the other rotational speed sensor can be arranged on the motor input shaft, the intermediate shaft or the output shaft.
The method for diagnosing the faults of the rotating speed sensor, provided by the embodiment of the application, is suitable for a gearbox controller and comprises the following steps:
when no rotating speed signal is input to a channel corresponding to the gearbox controller, determining that the corresponding rotating speed sensor has a second class fault, and generating a second class fault message to be sent to the whole vehicle controller of the vehicle.
The transmission controller determines a first rotational speed value/a second rotational speed value based on rotational speed signals output by the first rotational speed sensor/the second rotational speed sensor.
When the vehicle is electrified, the gearbox controller firstly determines whether the rotation speed sensor outputs no rotation speed signal, if so, determines that the corresponding rotation speed sensor fails, and reports the failure to the whole vehicle controller.
Referring to fig. 1, fig. 1 is a flowchart of a method for diagnosing a rotation speed sensor fault according to an embodiment of the present disclosure. As shown in fig. 1, when the vehicle is running, the transmission controller may then perform fault diagnosis by:
s101, acquiring a first rotating speed value acquired by a first rotating speed sensor and a second rotating speed value acquired by a second rotating speed sensor.
S102, determining a third rotating speed value of a target driving shaft in the hybrid gearbox based on the first rotating speed value.
And S103, determining a fourth rotating speed value of a target driving shaft in the hybrid gearbox based on the second rotating speed value.
When the target drive shaft is one of the intermediate shaft, the output shaft, or the engine input shaft, the third rotational speed value and the fourth rotational speed value are determined by:
the first rotational speed value is scaled based on a gear ratio between the motor input shaft and the target drive shaft to determine a third rotational speed value, and the second rotational speed value is taken as a fourth rotational speed value.
When the target drive shaft is the motor input shaft, the third and fourth rotational speed values are determined by: the second rotational speed value is scaled based on a gear ratio between the target drive shaft and the motor input shaft to determine a fourth rotational speed value, and the first rotational speed value is determined to be the third rotational speed value.
In steps S102 and S103, for the rotation speed sensors provided on different drive shafts, gear ratio conversion may be performed by the transmission ratio between the drive shafts, thereby obtaining a third rotation speed value and a third rotation speed value indicating the same drive shaft.
Illustratively, the conversion may be performed by the following formula:
wherein N is 1 For a first rotation speed value, N 3 X is the third rotation speed value a For the number of teeth corresponding to the input shaft of the motor, X b The number of teeth corresponding to the target drive shaft.
S104, determining the rotation speed sensor with one type of faults according to the deviation between the third rotation speed value and the fourth rotation speed value.
Referring to fig. 2, fig. 2 is a flowchart illustrating a diagnosis procedure of a fault rotation speed sensor according to an embodiment of the present application. As shown in fig. 2, a type of failed rotational speed sensor may be determined by:
s1040, calculating a first deviation value between the third rotation speed value and the average rotation speed value, and calculating a second deviation value between the fourth rotation speed value and the average rotation speed value.
S1042, determining whether the absolute value of the first deviation value or the second deviation value is greater than the preset deviation value.
Wherein the average rotation speed value is an average value between the third rotation speed value and the fourth rotation speed value. The preset deviation value is determined according to the average rotation speed value.
And S1044, if yes, determining the corresponding rotating speed sensor as the rotating speed sensor with one type of faults.
For example, the preset deviation value here may be 1% of the average rotation speed value. Taking the first rotation speed sensor as an example, when the absolute value of the deviation value is greater than 1% of the average rotation speed value, determining that the rotation speed of the first rotation speed sensor is out of limit, generating a type of fault, and reporting the fault to the whole vehicle controller so as to remind a user of timely maintenance and replacement.
Specifically, when the rotation speed sensor with one type of fault is determined, one type of fault message can be generated and sent to the whole vehicle controller of the vehicle based on the identification of the rotation speed sensor with one type of fault. The identification here may be the ID of the rotational speed sensor.
According to the method for diagnosing the faults of the rotating speed sensor, the rotating speed sensor is arranged on different driving shafts of the hybrid gearbox, fault diagnosis of the rotating speed sensor is carried out, accuracy of fault diagnosis of the rotating speed sensor in the hybrid gearbox is improved, and meanwhile normal running of an automobile is not affected when a single rotating speed sensor breaks down.
Example two
In one embodiment of the present application, the current vehicle speed value of the target vehicle may be determined by:
the transmission controller obtains a first rotating speed value acquired by a first rotating speed sensor and a second rotating speed value acquired by a second rotating speed sensor. And comparing the first rotating speed value with the second rotating speed value, and sending the maximum value between the first rotating speed value and the second rotating speed value to the whole vehicle controller so as to determine the current speed value of the target vehicle.
The whole vehicle controller can display the received rotation speed value to a user or detect driving safety.
In consideration of the normal running safety of the vehicle and the problem of overrun of the speed of the transmission, the embodiment selects the rotating speed sensor with higher rotating speed value as the rotating speed signal to output, so that the measuring accuracy of the vehicle speed detection is improved.
