Title:
METHOD FOR ACQUIRING ACCELERATOR PEDAL OPENING OF VEHICLE, ACTIVE SOUND-GENERATING SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/089533
Kind Code:
A1
Abstract:
A method for acquiring the accelerator pedal opening of a vehicle, an active sound-generating system and a vehicle. The method for acquiring the accelerator pedal opening comprises: measuring the opening of an accelerator pedal by using an angle sensor, an output signal of the angle sensor being analog voltage, and the analog voltage and the angle measured by the angle sensor having a linear change relationship; when the opening of the accelerator pedal is 0%, the angle tested by the angle sensor is α0
％, the corresponding analog voltage is V0%, and the corresponding angle of the accelerator pedal is 0°; when the opening of the accelerator pedal is 100%, the angle tested by the angle sensor is α100%, the corresponding analog voltage is V100%, and the corresponding angle of the accelerator pedal is α; and according to the linear change of the analog voltage and the angle measured by the angle sensor, information about the size of the accelerator pedal opening of a vehicle can be acquired merely by means of the change in angle of the angle sensor.
