Problems solved by technology

However, redesigning and testing requires too much time and cost, which may make it difficult to fulfill the time and cost stipulated by the project
[0005] Sometimes motor issues can be avoided with vehicle software calibration, however, in some extreme cases some NVH issues may arise even in production vehicles

Abstract

The invention relates to an NVH control method and system, and the method comprises the steps: a first obtaining step, which is used for obtaining parameters related to the performance of a motor of a vehicle; the calibration step is used for calibrating the NVH performance of the motor according to the obtained parameters; and a control step of controlling an NVH sound wave emitter according to the calibrated information so as to enable the NVH sound wave emitter to emit sound waves capable of suppressing the NVH of the motor, so that the NVH of the motor can be suppressed through the sound waves emitted by the NVH sound wave emitter, and the NVH problem of the motor can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular to an NVH control method and system. Background technique [0002] In the process of vehicle research and development, the performance of noise, vibration and harshness (English: Noise, Vibration, Harshness, NVH for short) is very important, because noise and vibration give the driver the most direct driving experience, and many vehicles Part of the company's research and development expenses are consumed in solving the NVH problem of the vehicle. [0003] Among them, the NVH problem is a difficult problem encountered in the development process of almost all electric motors (English: E-Machine, referred to as: EM), and it is very difficult to solve. Original Equipment Manufacturers (English: Original Equipment Manufacture, referred to as: OEM) Neither the customer nor the customer can afford the NVH problem, and sometimes even has to sacrifice the efficiency of the motor ...
