[0002] With the continuous development of vehicle technology, new energy power vehicles have become a new trend in the vehicle industry. In new energy power vehicles, an electric motor is used as a power source. The electric motor and its affiliated systems (including but not limited to cooling systems, lubrication systems, braking systems and protection systems) have cooling and lubrication requirements under operating conditions or idle conditions. Therefore, an oil pump system needs to be installed in the vehicle to meet these requirements by using the oil pump system to supply oil.

[0072] In a possible implementation, when the developer of the first vehicle designs the first vehicle, the acceptable noise values of each driving position of the first vehicle at each vehicle speed and each frequency can be designed. When the acceptable noise values of each driving position of the first vehicle at each vehicle speed and each frequency are designed, the acceptable noise values of each driving position of the first vehicle at each vehicle speed and each frequency can be directly obtained.

[0073] In the case where the acceptable noise values of each driving position of the first vehicle at each vehicle speed and each frequency are not designed, the noise values received by each driving position of the second vehicle at each vehicle speed and each frequency can be obtained; and the acceptable noise values of each driving position of the first vehicle at each vehicle speed and each frequency are determined according to the reference value and the noise values received by each driving position of the second vehicle at each vehicle speed and each frequency.

[0074] The second vehicle is determined based on the first vehicle, the second vehicle is a competitive vehicle of the first vehicle, and the second vehicle is a vehicle that has been developed.

[0075] The process of obtaining the noise values 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 values received by each driving position of the second vehicle at each vehicle speed and each frequency.

[0076] In a possible implementation, the process of determining the acceptable noise values of each driving position of the first vehicle at each vehicle speed and each frequency according to the reference value and the noise values received by each driving position of the second vehicle at each vehicle speed and each frequency includes: for the acceptable noise value of the first driving position of the first vehicle at the first vehicle speed and the first frequency, determining the first sum of the reference value and the noise value received by the first driving position of the second vehicle at the first vehicle speed and the first frequency; and determining that the first sum is the acceptable noise value of the first driving position of the first vehicle at the first vehicle speed and the first frequency.

The second sum value is a sum value between the acceptable noise value of the first passenger position at the first vehicle speed and the first frequency, and the noise attenuation amount of the first passenger position at the first frequency. The number of second sum values is the number of frequencies corresponding to the first vehicle speed. The first passenger position is any passenger position in the plurality of passenger positions. The first frequency is any frequency corresponding to the first vehicle speed.

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

[0087] In step 204, noise values emitted by the reference oil pump system at each speed and each frequency are obtained.

[0088] In a possible implementation, the noise values emitted by the reference oil pump system at each speed and each frequency refer to the audible noise values emitted by the reference oil pump system at each speed and each frequency at a target distance from the reference oil pump system in an anechoic chamber environment.

[0089] The target distance is set based on experience or adjusted according to the implementation environment, and the embodiments of the present application do not limit this. For example, the target distance is 10 centimeters.

[0090] Optionally, the difference between two adjacent speeds in the plurality of speeds is a target difference. The target difference is set based on experience or adjusted according to the implementation environment, and the embodiments of the present application do not limit this. For example, 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 do not limit the reference oil pump system.

[0092] In step 205, the required operating speed of the first vehicle at each vehicle speed for the oil pump system is determined according to the required noise value of the first vehicle at each vehicle speed for the oil pump system and the noise value of the reference oil pump system at each speed and each frequency.

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

[0095] Optionally, the required operating speed of the first vehicle at each vehicle speed for the oil pump system refers to the required operating speed of the first vehicle at each vehicle speed for the oil pump system in terms of NVH (Noise, Vibration, Harshness) performance.

[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 minimum operating speed of the first vehicle at each vehicle speed for the oil pump system is not greater than the required operating speed of the first vehicle at each vehicle speed for the oil pump system.

[0097] In a possible implementation, the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is also acquired. The minimum 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 by the electric drive assembly of the first vehicle at each vehicle speed due to the 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 the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed is acquired, 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 a case where 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 a case where 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, the process returns to step 204 to re-acquire the noise value emitted by the other oil pump system at each speed and each frequency, to 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 value emitted by the other oil pump system at each speed and each frequency, and to determine the other oil pump system to be the oil pump system of the first vehicle based on 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.

For example, the minimum operating speed of the oil pump system of the first vehicle at the first vehicle speed is the first speed, and the reference oil pump system is controlled to operate at the first speed when the first vehicle travels at the first vehicle speed. Since the lower the speed of the oil pump system of the vehicle, the lower the noise value emitted by the oil pump system, the reference oil pump system is controlled to operate at the minimum operating speed of the oil pump system of the first vehicle at each vehicle speed, which can reduce the noise value emitted by the oil pump system to a certain extent.
