Figure 1 The computer device 101 in the embodiment is executed. Figure 2 As shown, the method includes the following steps 201 to 206.

[0068] In step 201 , acceptable noise values ​​at various driving positions of a first vehicle at various vehicle speeds and various frequencies are obtained.

[0069] In a possible implementation, the driving position of the first vehicle is determined based on the number of people that the first vehicle can take. Based on the number of people that the first vehicle can take is 5, the driving position of the first vehicle includes the front window position and the rear window position of the first vehicle. That is, the driving position of the first vehicle includes the main driving position, the co-pilot position, the position behind the main driving position, and the position behind the co-pilot position of the first vehicle. Based on the number of people that the first vehicle can take is 6 or 7, the driving position of the first vehicle includes the front window position, the middle row window position, and the rear window position of the first vehicle.

Wherein, the first value, the second value and the third value are set based on experience, or adjusted according to the implementation environment, and the embodiment of the present application does not limit this. Exemplarily, the second value is 0 km / h, the third value is 80 km / h, and the first value is 5 km / h. Then each vehicle speed includes 0 km / h, 5 km / h, 10 km / h, 15 km / h, 20 km / h, 25 km / h, 30 km / h, 35 km / h, 40 km / h, 45 km / h, 50 km / h, 55 km / h, 60 km / h, 65 km / h, 70 km / h, 75 km / h, and 80 km / h.

[0071] The difference between two adjacent frequencies in each frequency is a fourth value, the minimum frequency in each frequency is a fifth value, the maximum frequency is a sixth value, and the fifth value is less than the sixth value. Wherein, the fourth value, the fifth value and the sixth value are set based on experience, or adjusted according to the implementation environment, and the embodiment of the present application is not limited to this. Exemplarily, the fourth value is 198, the fifth value is 20 Hz (HZ), and the sixth value is 2000 Hz. Then each frequency includes 20 Hz, 218 Hz, 416 Hz, 614 Hz, 812 Hz, 1010 Hz, 1208 Hz, 1406 Hz, 1604 Hz, 1802 Hz, and 2000 Hz.

[0072] In a possible implementation, when designing the first vehicle, the developer of the first vehicle may design acceptable noise values ​​for various driving positions of the first vehicle at various vehicle speeds and various frequencies. After designing the acceptable noise values ​​for various driving positions of the first vehicle at various vehicle speeds and various frequencies, the acceptable noise values ​​for various driving positions of the first vehicle at various vehicle speeds and various frequencies may be directly obtained.

[0073] In the case that the acceptable noise values ​​for each driving position of the first vehicle at each vehicle speed and each frequency have not been designed, the noise values ​​received by each driving position of the second vehicle at each vehicle speed and each frequency can be obtained; based on the reference values ​​and the noise values ​​received by each driving position of the second vehicle at each vehicle speed and each frequency, the acceptable noise values ​​for each driving position of the first vehicle at each vehicle speed and each frequency are determined.

[0074] Among them, the second vehicle is determined based on the first vehicle, the second vehicle is a competing vehicle of the first vehicle, and the second vehicle is a vehicle that has already been developed.

[0075] The process of obtaining the noise value received by each driving position of the second vehicle at each vehicle speed and each frequency includes: testing the second vehicle to obtain the noise value received by each driving position of the second vehicle at each vehicle speed and each frequency.

[0076] In one possible implementation, the process of determining acceptable noise values ​​for each riding position of the first vehicle at each vehicle speed and each frequency based on a reference value and noise values ​​received at each riding position of the second vehicle at each vehicle speed and each frequency includes: determining a first sum of the reference value and the noise values ​​received at the first riding position in the second vehicle at the first vehicle speed and the first frequency for the acceptable noise value of the first riding position of the first vehicle at the first vehicle speed and the first frequency; and determining the first sum as the acceptable noise value for the first riding position of the first vehicle at the first vehicle speed and the first frequency.

[0077] The first riding position is any riding position among various riding positions, the first vehicle speed is any vehicle speed among various vehicle speeds, and the first frequency is any frequency among frequencies corresponding to the first vehicle speed. The reference value is set based on experience, or adjusted according to the implementation environment, and the embodiment of the present application does not limit this. For example, the reference value is 3 decibels (db), and for another example, the reference value is 5 decibels.

[0078] Exemplarily, the reference value is 3 decibels, and the noise value received by the first driving position of the second vehicle at the first vehicle speed and the first frequency is A, then the acceptable noise value of the first driving position of the first vehicle at the first vehicle speed and the first frequency is determined to be A+3.

[0079] Optionally, the acceptable noise value at each driving position of the first vehicle at each vehicle speed and each frequency may be the sound pressure level at each driving position of the first vehicle at each vehicle speed and each frequency.

[0081] The noise attenuation at any driving position at any frequency refers to the attenuation of the noise emitted from the reference position transmitted to any driving position at any frequency, and the reference position is the position where the oil pump system is installed in the first vehicle. The transmission path of the noise emitted from the reference position to any driving position is an air path.

[0082] In step 203, the required noise value of the oil pump system of the first vehicle at each vehicle speed is determined according to the acceptable noise value of each driving position at each vehicle speed and each frequency and the noise attenuation of each driving position at each frequency.

[0083] In one possible implementation, the process of determining the required noise value for the oil pump system of the first vehicle at each vehicle speed based on the acceptable noise value for each driving position at each vehicle speed and each frequency and the noise attenuation amount of each driving position at each frequency includes: for the required noise value for the oil pump system of the first vehicle at the first vehicle speed, determining the required noise value for the oil pump system of each driving position at the first vehicle speed based on the acceptable noise value for each driving position at the first vehicle speed and each frequency and the noise attenuation amount of each driving position at each frequency, the first vehicle speed being any vehicle speed among the various vehicle speeds; and taking the required noise value that meets the first requirement among the required noise values ​​for the oil pump system of each driving position at the first vehicle speed as the required noise value for the oil pump system of the first vehicle at the first vehicle speed.

[0084] Optionally, the process of determining the required noise value of the oil pump system for each riding position at the first vehicle speed according to the acceptable noise value of each riding position at the first vehicle speed and each frequency and the noise attenuation amount of each riding position at each frequency includes: determining a plurality of second sum values ​​for the first riding position among the various riding positions; and determining the required noise value of the oil pump system for the first riding position at the first vehicle speed according to the plurality of second sum values. The second sum value is the sum of the acceptable noise value of the first riding position at the first vehicle speed and the first frequency and the noise attenuation amount of the first riding position at the first frequency, the number of the second sum values ​​is the number of frequencies corresponding to the first riding position at the first vehicle speed, the first riding position is any riding position among the various riding positions, and the first frequency is any frequency among the frequencies corresponding to the first vehicle speed.

[0085] In a possible implementation, the embodiment of the present application does not limit the process of determining the required noise value of the oil pump system at the first vehicle speed for the first driving position based on multiple second sums. Optionally, the process of determining the required noise value of the oil pump system at the first vehicle speed for the first driving position based on multiple second sums includes: determining the maximum value among the second sums as the required noise value of the oil pump system at the first vehicle speed for the first driving position; or determining the minimum value among the second sums as the required noise value of the oil pump system at the first vehicle speed for the first driving position; or determining the average value of multiple second sums, and determining the average value as the required noise value of the oil pump system at the first vehicle speed for the first driving position.

[0086] Optionally, the required operating speed of the oil pump system of the first vehicle at each vehicle speed refers to the operating speed of the oil pump system required of the first vehicle at each vehicle speed when a reference oil pump system is installed in the first vehicle.

[0087] In step 204 , the noise values ​​emitted by the reference oil pump system at various rotation speeds and various frequencies are obtained.

[0088] In one possible implementation, the noise value emitted by the reference oil pump system at each speed and each frequency refers to the noise value emitted by the reference oil pump system at each speed and each frequency that can be heard in an anechoic chamber environment at a target distance from the reference oil pump system.

[0089] The target distance is set based on experience or adjusted according to the implementation environment, which is not limited in the embodiment of the present application. For example, the target distance is 10 centimeters.

[0090] Optionally, the difference between two adjacent rotational speeds in each rotational speed is a target difference. The target difference is set based on experience or adjusted according to the implementation environment, and the embodiment of the present application does not limit this. Exemplarily, the target difference is 100 revolutions per minute (rpm).

[0091] The reference oil pump system is any oil pump system, and the embodiments of the present application are not limited to this.

[0092] In step 205, the required operating speed of the oil pump system of the first vehicle at each vehicle speed is determined based on the required noise value of the oil pump system of the first vehicle at each vehicle speed and the noise value emitted by the reference oil pump system at each speed and each frequency.

[0093] In one possible implementation, the process of determining the required operating speed of the oil pump system of the first vehicle at each vehicle speed based on the required noise value of the oil pump system of the first vehicle at each vehicle speed and the noise value emitted by the reference oil pump system at each rotational speed and each frequency includes: determining a first noise value for the required operating speed of the oil pump system of the first vehicle at the first vehicle speed based on the required noise value of the oil pump system of the first vehicle at each vehicle speed, the first noise value being the required noise value of the oil pump system of the first vehicle at the first vehicle speed, the first vehicle speed being any one of the various vehicle speeds; determining a rotation speed corresponding to the first noise value based on the noise value emitted by the reference oil pump system at each rotational speed and each frequency; and determining the required operating speed of the oil pump system of the first vehicle at the first vehicle speed based on the rotational speed corresponding to the first noise value.

[0095] Optionally, the required operating speed of the oil pump system of the first vehicle at each vehicle speed refers to the required operating speed of the oil pump system of the first vehicle according to NVH (noise, vibration, harshness) performance at each vehicle speed.

[0096] In step 206 , the reference oil pump system is determined to be the oil pump system of the first vehicle based on the fact that the lowest operating speed of the oil pump system of the first vehicle at each vehicle speed is not greater than the required operating speed of the oil pump system of the first vehicle at each vehicle speed.

[0097] In a possible implementation, the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is also required to be obtained. The minimum operating speed of the oil pump system of the first vehicle at each vehicle speed refers to the operating speed required by the oil pump system of the first vehicle at each vehicle speed corresponding to the electric drive assembly due to cooling and lubrication performance requirements. The minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is set by the developer of the first vehicle.

[0098] Optionally, after obtaining the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed, it is determined whether the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is greater than the required operating speed of the oil pump system of the first vehicle at each vehicle speed. In the case that the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is not greater than the required operating speed of the oil pump system of the first vehicle at each vehicle speed, the reference oil pump system is determined to be the oil pump system of the first vehicle.

[0099] In the case that the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is greater than the required operating speed of the oil pump system of the first vehicle at each vehicle speed, it is necessary to return to step 204 to re-acquire the noise values ​​emitted by other oil pump systems at each speed and each frequency; determine the required operating speed of the oil pump system of the first vehicle at each vehicle speed according to the required noise value of the oil pump system of the first vehicle at each vehicle speed and the noise values ​​emitted by other oil pump systems at each speed and each frequency; determine the other oil pump system as the oil pump system of the first vehicle based on the fact that the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is not greater than the required operating speed of the oil pump system of the first vehicle at each vehicle speed. This process is similar to the process of step 205 and step 206, and the embodiment of the present application will not be repeated here.

[0100] In a possible implementation, after determining that the reference oil pump system is the oil pump system of the first vehicle, the reference oil pump system can be installed in the first vehicle when the first vehicle is produced. When the reference oil pump system is installed in the first vehicle, the reference oil pump system is controlled according to the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed. That is, according to the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed, the reference oil pump system is controlled to operate at the minimum operating speed. For example, the minimum operating speed of the oil pump system of the first vehicle at the first vehicle speed is the first speed, then when the first vehicle is traveling at the first vehicle speed, the reference oil pump system is controlled to operate at the first speed. Since the lower the speed of the oil pump system of the vehicle, the lower the noise value emitted by the operation of the oil pump system, therefore, when the reference oil pump system is operated according to the minimum operating speed of the oil pump system at each vehicle speed, the noise value emitted by the oil pump system can be reduced to a certain extent.

[0101] When determining the oil pump system of the vehicle, the above method determines whether the reference oil pump system can be used as the oil pump system of the vehicle according to the acceptable noise values ​​of different driving positions of the vehicle at different vehicle speeds and different frequencies, the noise attenuation values ​​of different driving positions at different frequencies, and the noise values ​​emitted by the reference oil pump system at different speeds and different frequencies. The reference oil pump system is used as the oil pump system of the vehicle only when the minimum operating speed of the oil pump system at each vehicle speed is not greater than the required operating speed of the oil pump system at each vehicle speed. A new method for determining the oil pump system is provided, which makes the determination method of the oil pump system more diversified and flexible, and the determined oil pump system has a higher matching degree with the first vehicle. Moreover, when determining the oil pump system, the acceptable noise of the driving position is taken into account, so that the noise of the determined oil pump system is smaller, thereby improving the comfort of the driver and passengers in the vehicle and improving the sound quality of the vehicle.
