Abstract

The invention discloses a method and device for determining noise performance parameters of a wiper motor, and aims to at least solve the problems of poor control effect, high cost and long period inan existing wiper motor noise control scheme. The method comprises the following steps: acquiring a target noise value of a wiper motor in a cab of a vehicle and an initial noise performance parameterof the wiper motor, wherein the initial noise performance parameters comprise an initial noise transfer function NTF from an installation point of the wiper motor on the vehicle to the cab and initial suspension parameters of a suspension device of the wiper motor; determining the vibration displacement of the wiper motor at the mounting point based on the target noise value and the initial noiseperformance parameter; predicting a noise value generated by the wiper motor in the cab based on the vibration displacement; and determining a target noise performance parameter of the wiper motor based on the predicted noise value, the target noise value and the initial noise performance parameter.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a method and device for determining noise performance parameters of a wiper motor. Background technique [0002] With the rapid development of the vehicle industry, consumers have higher and higher requirements for the ride comfort and sound quality of vehicles. The running noise of the wiper of the vehicle is one of the sound sources when the vehicle is stationary and driving at medium and low speeds, especially for electric vehicles, because electric vehicles do not have an engine, and there is no masking effect of engine sound when the vehicle is stationary and driving at medium and low speeds. protrude. The operating noise of the wiper mainly includes the impact sound when the wiper blade changes direction, the friction sound of the wiper blade and the noise of the wiper motor. The frequency range of the wiper motor noise is wide, and the sound quality is poor. T...
