It is understood that the generator torque output time refers to the time when the hybrid generator generates a drag torque, and the target generator output torque refers to the time when the generator generates the drag torque when it is turned off, for example: the target generator output torque may be 20nxm, and the generator torque output time may be 0.5S, which is not particularly limited in the present embodiment.

Referring to fig. 6, fig. 6 is a schematic flow chart illustrating a method for controlling abnormal noise during flameout of a generator according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, before the step S20, the method further includes:
step S110: and acquiring the generator torque output time and the generator output torque of the target vehicle.
It should be noted that, in order to obtain the optimal generator torque output time and the optimal generator output torque at the current rotation speed, a generator of the target vehicle needs to be tested, and in this embodiment, the optimal generator torque output time and the optimal generator output torque at the current rotation speed can be obtained through testing by changing the generator torque output time and the generator output torque at the same rotation speed of the generator.
Further, the step S110 includes:
acquiring the output power and the torque output time of a generator of the target vehicle;
and determining the output torque of the generator according to the output power, the current rotating speed of the generator and a preset torque threshold value.
The formula for obtaining the output torque of the generator is as follows:
wherein T is the torque of the generator, the preset torque threshold is 9550, P is the output power, and N is the current rotating speed of the generator.
Step S120: initial vehicle response information is determined based on the generator torque output time and generator output torque.
It should be noted that the vehicle response information may be vehicle shake information and noise information, where the vehicle shake information includes: vehicle steering wheel shake information, vehicle seat guide rail shake information and generator body shake information etc. and vehicle noise information includes: cabin noise, driver right ear noise in the cab, and the like, which is not particularly limited in this embodiment.

TABLE 1
Further, the step S130 includes:
adjusting the torque output time of the generator and the output torque of the generator according to the sweep frequency test request;
determining target vehicle response information based on the adjusted generator torque output time and the adjusted generator output torque;
and comparing the initial vehicle response information with the target vehicle response information, and generating a generator flameout control strategy according to the comparison result.
In specific implementation, the shake condition and the noise condition of the target vehicle under different conditions are obtained by adjusting the torque output time of the generator and the output torque of the generator.
Further, the comparing the initial vehicle response information with the target vehicle response information and generating a generator stall control strategy according to the comparison result includes:
generating an initial response coefficient according to the initial jitter information, the initial noise information and the preset response weight;
generating a target response coefficient according to the target jitter information, the target noise information and the preset response weight;
and comparing the initial response coefficient with the target response coefficient, and according to the comparison result, carrying out flameout control on the target generator.
It should be noted that the preset response weight may be a weight ratio of the steering wheel shake information, the seat rail shake information, and the noise in the right ear area of the cab, for example: 2.
It should be understood that the response coefficient refers to a parameter value obtained by quantizing the jitter information and the noise information according to a preset response weight.
Further, the comparing the initial response coefficient with the target response coefficient and generating a target generator flameout control strategy according to the comparison result includes:
when the initial response coefficient is larger than the target response coefficient, outputting target generator torque output time and target generator output torque corresponding to the target response coefficient;
and when the initial response coefficient is not larger than the target response coefficient, outputting the generator torque output time and the generator output torque corresponding to the initial response coefficient.
In the specific implementation, the generator torque output time and the generator output torque with smaller response coefficients are output to serve as the optimal generator torque output time and the optimal generator output torque at the current generator rotating speed, so that the vehicle abnormity and the vehicle vibration are reduced to the greatest extent.
The embodiment discloses obtaining the generator torque output time and the generator output torque of the target vehicle; determining initial vehicle response information based on the generator torque output time and generator output torque; when a frequency sweep test request is received, performing frequency sweep test on the generator of the target vehicle according to the generator torque output time, the generator output torque and the initial vehicle response information, and determining a generator flameout control strategy based on a frequency sweep test result.

Based on the second embodiment, in this embodiment, the step S30 includes:
step S301: and acquiring the current generator torque output time and the current generator output torque of the target vehicle.
It is easy to understand that when the vehicle is running, if the vehicle suddenly stops working, there may exist a certain current generator torque output time and a certain current generator output torque, but the current generator torque output time and the current generator output torque cannot meet the requirement of the vehicle generator for stable rotation speed, and it is also necessary to adjust the generator torque output time and the generator output torque to obtain the stable rotation speed of the generator.
Step S302: determining a torque output time to be adjusted based on the current generator torque output time and the target generator torque output time, and determining a torque difference to be adjusted based on the current generator output torque and the target generator output torque.
It is easy to understand that the torque output time to be adjusted refers to a difference value between the current generator torque output time and the target generator torque output time, and the torque difference value to be adjusted refers to a torque difference value between the current generator output torque and the target generator output torque.
Step S303: and controlling the running state of the generator of the target vehicle according to the torque difference value to be adjusted and the torque output time to be adjusted.
The embodiment discloses obtaining the current generator torque output time and the current generator output torque of a target vehicle; determining a torque output time to be adjusted based on the current generator torque output time and the target generator torque output time, and determining a torque difference to be adjusted based on the current generator output torque and the target generator output torque; according to the method and the device for controlling the running state of the generator of the target vehicle, the running state of the generator of the target vehicle is controlled according to the torque difference value to be adjusted and the torque output time to be adjusted.
