The invention relates to the technical field of accelerator pedal opening degree obtaining and discloses a vehicle accelerator pedal opening degree obtaining method, an active sound production systemand a vehicle. The accelerator pedal opening degree obtaining method comprises steps that the opening degree of an accelerator pedal is measured through an angle sensor, an output signal of the anglesensor is analog voltage, and the analog voltage and the angle measured by the angle sensor are in a linear change relation; when the accelerator pedal is in the 0% opening degree, the test angle of the angle sensor is alpha 0%, the corresponding analog voltage quantity is V 0%, and the corresponding angle of the accelerator pedal is 0 degree; when the accelerator pedal is in the 100% opening degree, a test angle of the angle sensor is alpha 100%, the corresponding analog voltage quantity is V 100%, the corresponding angle of the accelerator pedal is alpha, and according to the linear change of the analog voltage quantity and the angle measured by the angle sensor, the change of the angle of the accelerator pedal can be obtained only through the change of the angle of the angle sensor; therefore, the information of the opening degree of the accelerator pedal of the vehicle can be obtained.
本发明涉及加速踏板开度获取技术领域,公开了一种车辆加速踏板开度获取方法、主动发声系统及车辆;加速踏板开度获取方法包括:采用角度传感器测量加速踏板的开度,角度传感器的输出信号为模拟电压量,且模拟电压量与角度传感器所测得的角度呈线性变化关系;加速踏板处于0%开度时,角度传感器测试的角度为α0%,对应的模拟电压量为V0%,加速踏板对应的角度为0°;加速踏板处于100%开度时,角度传感器测试的角度为α100%,对应的模拟电压量为V100%,加速踏板对应的角度为α,根据模拟电压量与角度传感器所测得的角度呈线性变化得到仅需通过角度传感器角度的变化,便可获取车辆加速踏板开度的大小的信息。
