Based on the implementation architecture of fig. 1, the present embodiment provides a method for monitoring vibration noise of a hybrid transmission, which is executed by the electronic device 100 shown in fig. 1, and the following describes in detail steps of the method for monitoring vibration noise of a hybrid transmission provided in the present embodiment based on a structure diagram of the electronic device 100 shown in fig. 1, and with reference to fig. 2, the method for monitoring vibration noise of a hybrid transmission includes steps 101 to 103:
step 101: and acquiring a target monitoring signal of the component to be detected.
In this embodiment, the hybrid transmission is a multi-gear hybrid dedicated transmission, and the driving modes include a pure electric drive, an engine direct drive, a series mode, a parallel mode, an ECVT mode, and the like. The part to be tested of the hybrid transmission comprises a vibration part to be tested and a noise part to be tested, wherein the vibration part to be tested comprises a gear, a generator, a driving motor, a bearing and the like, and the noise part to be tested comprises a part which is close to the hybrid transmission side in a vehicle cabin and a part which is close to the inner right side of a headrest of a main driving seat. In order to obtain a target monitoring signal of a component to be detected, in this embodiment, a vibration sensor or an acceleration sensor is arranged on a housing of a main component such as a gear, a generator, a driving motor, a bearing, and the like, and a noise sensor, for example, a near-field microphone, is arranged on a side of a vehicle cabin close to a hybrid transmission and on a right side of a main driver seat headrest, and is used for detecting abnormal noise of the transmission and simulating a noise level received by a right ear of a driver. It should be noted that, in this embodiment, the sensors may be disposed on the vibration component to be measured and the noise component to be measured at the same time, or the sensors may be disposed on the vibration component to be measured or the noise component to be measured separately. After the sensor is arranged on the component to be detected, the target monitoring signal of the component to be detected, which is acquired by the vibration sensor and the noise sensor, can be acquired.
Step 102: and carrying out order processing on the acquired target monitoring signal, and determining to obtain target order data of the component to be detected.
After the target monitoring signal is obtained, the target monitoring signal is subjected to order processing to obtain target order data of the component to be detected. In the present embodiment, the target monitoring signal includes a vibration signal and/or a noise signal; the corresponding target order data includes order vibrations and/or order noise.
From the target order data we can derive the order of the target order data. It should be noted that each component under test may generate multiple orders of vibration and/or noise, for example, a 32-tooth gear may generate 32, 64, etc. orders of noise or noise. In order to avoid resonance, the order vibration and/or the order noise generated by each component is different from each other in consideration of resonance avoidance at the beginning of vehicle design, that is, each order vibration and/or order noise corresponds to a unique component.
Step 103: and comparing the target order data with a preset threshold, and if the target order data is greater than the preset threshold, adjusting the driving strategy.
During the operation of a vehicle, when each rotating part of the hybrid transmission rotates, vibration and noise can generate corresponding order characteristics, and when the rotating parts are abnormal, the order characteristics can be highlighted to influence the vibration noise total magnitude of the system. Based on the above, whether the order vibration or the order noise exists, a corresponding preset threshold is set for each order vibration and/or order noise, the target order data is compared with the preset threshold, and if the target order data is smaller than or equal to the preset threshold, the noise is not abnormal. And if the target order data is larger than a preset threshold value, indicating that the noise is abnormal. Specifically, the target order noise with the same order as the order of the noise is obtained from the historical abnormal order noise, the sound pressure values corresponding to the target order noises are summed and averaged, and the average value is used as the preset threshold value corresponding to the order of the noise.
It should be noted that, when a hybrid transmission product is developed, main components such as a motor and a gear cannot meet the NVH design target under all working conditions and reach the NVH design target all the time due to factors such as design, manufacture, installation, cost and durability. Generally, after a vehicle travels for a certain distance, tooth surfaces of a pair of parallel gears are abraded due to meshing, so that squeaking can be generated under a certain rotating speed and specific torque working condition, and the squeaking phenomenon is obviously improved when the rotating speed or the torque is changed. Therefore, after determining the component causing the noise abnormality, the occurrence of the abnormal vibration noise may be improved or avoided by adjusting the driving strategy, such as adjusting the engine torque, the rotation speed, the driving motor torque, the rotation speed, the generator torque, the rotation speed, or adjusting the gear.
Specifically, adjusting the driving strategy may include:
step 201: and determining an abnormal noise component from the component to be tested according to the order of the target order data.
Step 202: and adjusting the driving strategy according to the determined abnormal noise component.
The order of the target order data can be determined according to the target order data, and as described in the foregoing, each order corresponds to a unique component, so that a component generating abnormal noise can be determined from the components to be tested according to the order. Specifically, a to-be-tested part corresponding to the order of the target order data may be matched in an order-part comparison table, the to-be-tested part may be set as an abnormal noise part, and the order-part comparison table may include a plurality of orders and a to-be-tested part corresponding to each order. For example, the order-component look-up table includes 4 th order noise and its corresponding gear a,8 th order noise and its corresponding gear a,6 th order noise and its corresponding gear B,12 th order noise and its corresponding gear B. When the order of the order noise needing to be matched is 6, the gear B of the part to be tested corresponding to the order noise can be found through the order-part comparison table, namely the gear B is an abnormal noise part. For another example, the order-component comparison table includes 3 order oscillations and their corresponding gears a,6 order oscillations and their corresponding gears B,9 order oscillations and their corresponding gears C. When the order of the order vibration needing to be matched is 6, the gear B of the part to be tested corresponding to the order vibration can be found through the order-part comparison table, namely the gear B is an abnormal noise part.
After the abnormal noise component is determined, the driving strategy can be adjusted according to the determined abnormal noise component, and in detail, the method can comprise the following steps:
searching whether a target component and a target order which are matched with the abnormal noise component and the order of the abnormal noise component exist in a historical strategy library;
if yes, setting the historical strategy corresponding to the target component and the target order as a reference strategy;
and adjusting the driving strategy according to the reference strategy.
The historical strategy library stores the component characteristics and the solving strategy of the conventional abnormal noise, and the component characteristics of the embodiment can be the component names and the orders of the abnormal noise. If the condition of the abnormal noise generated at present is similar to the prior condition, namely a target component and a target order which are matched with the abnormal noise component and the order thereof are found in the historical strategy library, setting the historical strategy corresponding to the target component and the target order as a reference strategy; and adjusting the driving strategy according to the reference strategy.
Note that, after the driving strategy is adjusted, in order to determine whether the abnormal noise is improved, it may be:
re-acquiring a target monitoring signal of the component to be detected, and determining to obtain target order data of the component to be detected;
and comparing the target order data with a preset threshold, and if the target order data is greater than the preset threshold, readjusting the driving strategy. It should be noted that one way to adjust the driving strategy is by adjusting the driving motor torque, the generator torque, and the engine torque. Namely, the sum of the torque of the driving motor, the torque of the generator and the torque of the engine is kept unchanged, and simultaneously, the torque of the driving motor is increased, and the torque of the generator and the torque of the engine are reduced; or the torque of the driving motor is reduced and the torque of the generator and the torque of the engine are increased while the sum of the torque of the driving motor, the torque of the generator and the torque of the engine is kept unchanged. The adjustment mode does not affect the driving feeling of the passenger.
The other adjustment mode is to adjust the rotating speed of the sun wheel of the generator, the rotating speed of the planet carrier of the engine and the rotating speed of the gear ring and satisfy n 1 +2.6n 2 -3.6n 3 =0, wherein n 1 Is the sun wheel speed, n, of the generator 2 Is the rotational speed of the ring gear, n 3 Is the engine's planet carrier speed. The gear ring is connected with a differential (wheel edge) through gear meshing, and the wheel edge speed can be ensured to be unchanged by the adjusting mode.
In this embodiment, after the above-mentioned various adjustments are performed, if the re-detection result still indicates that the target order data is greater than the preset threshold, it needs to be considered whether the transmission component is faulty or not.
In detail, the target monitoring signal of the component to be detected is obtained again, and the target order data of the component to be detected is determined; and comparing the target order data with a preset threshold, and if the target order data is greater than the preset threshold, sending fault alarm information.
Meanwhile, considering that different people have different sensitivities and recognition degrees to noise, a driver can actively mark abnormal noise, a microphone is arranged on the right ear side of the driver, the microphone simulates the right ear of the driver, noise data are collected, and reason analysis is carried out. When the system fails to identify abnormal noise or reasons, a driver can upload current noise and working condition information and subjective feeling description to the network through the Internet of vehicles, and an NVH (noise, vibration and harshness) engineer can analyze the abnormal noise and put forward an improvement strategy in a background.
