Embodiment approach

[0061] Optionally, in another embodiment of the present application, an implementation of step S102 specifically includes:

[0062] The throttle signal voltage value is divided by the actual power supply voltage value to obtain the first result value.

[0063] The first result value is multiplied by the calibrated supply voltage value to obtain the second result value.

[0064] The difference between the accelerator signal voltage value and the second result value is obtained to obtain a signal correction value of the accelerator pedal sensor.

[0065] It should be noted that the calculation formula V 0 =(k*r 0 +b)*Us, it can be concluded that when the power supply voltage of the accelerator pedal sensor provided by the ECU deviates, when the accelerator pedal opening is r 0 When , the signal correction value of the accelerator pedal sensor:

[0066] ΔV 0 =V 0 '-V 0 =(k*r 0 +b)*Us’-(k*r 0 +b)*5=V 0 '-5*V 0 ' / Us'

[0067] Among them, V 0 ’ is the throttle signal vo...

Abstract

The present application provides a method and device for adjusting an accelerator signal, by obtaining the actual power supply voltage value of the accelerator pedal sensor and the voltage value of the accelerator signal output by the accelerator pedal sensor. Wherein, the accelerator signal voltage value is obtained by converting the accelerator position information detected by the accelerator pedal sensor, and the accelerator pedal opening can be obtained from the accelerator signal voltage value. Then the actual power supply voltage value and the accelerator signal voltage value are used to calculate the signal correction value of the accelerator pedal sensor. Then make a difference between the accelerator signal voltage value and the signal correction value of the accelerator pedal sensor to obtain the corrected accelerator signal voltage value. The corresponding accelerator pedal opening can be obtained from the corrected accelerator signal voltage value, and the accelerator signal can be transmitted accurately.

Description

technical field [0001] The present application relates to the technical field of the automobile industry, in particular to a method and device for adjusting an accelerator signal. Background technique [0002] With the development of the automobile industry, the number of automobiles continues to increase. Automobiles are the most commonly used means of transportation for people, which greatly facilitates people's travel. In a car, power is a relatively important indicator, which will affect the power of the car. In addition to the performance of the engine and gearbox, the throttle response is also a relatively important item. The sensor in the engine control system is the main device for ECU (Electronic Control Unit, electronic control unit) information acquisition, and the accuracy of sensor signal processing affects the control accuracy of the electronic control system. An accelerator pedal position sensor will be set at the accelerator pedal to transmit the signal of t...
