The calibration zero clearing button 16 is used for realizing the zero calibration of the top dead center position of the accelerator pedal.
In the embodiment, the controller 1 may be configured to supply power to the vehicle through a 13V low-voltage battery, or may be provided with a power module. In this embodiment, a power supply logic is introduced by supplying power to the controller 1 through the on-board 13V low-voltage battery, as shown in fig. 3, under this condition, the controller 1 needs to be connected to a socket reserved for the on-board 13V low-voltage battery through a conductive harness plug connector, the other end of the conductive harness plug connector is respectively connected to a power supply pin of a chip inside the controller 1, the display panel 12, the switch control button 13, the pedal opening increase control button 14, the pedal opening decrease control button 15 and the calibration clear button 16, meanwhile, one pin of the control chip 11 inside the controller 1 is grounded, and correspondingly, the switch control button 13, the pedal opening increase control button 14, the pedal opening decrease control button 15 and the calibration clear button 16 are respectively grounded. Of course, in order to control the opening and closing of the display panel 12 by the control chip 11 according to the control signal of the switch control panel 13, a switch 17 is provided between the display panel 12 and the 12V low-voltage battery 2, the switch 17 is connected to one of the pins of the control chip 11 through a signal wire harness, and the control chip 11 sends a trigger signal to the switch 17 to trigger the opening and closing control of the switch 17, so as to control the opening and closing of the display panel 12.

During the test, the pedal opening increasing control button 14 and the pedal opening decreasing control button 15 are needed to realize the target accelerator opening setting, the target accelerator opening value is increased or decreased by 5% when the pedal opening increasing control button 14 or the pedal opening decreasing control button 15 is clicked once, the setting is finished and then the controller 1 waits for 5 seconds, and then the controller starts to replace an accelerator pedal to perform information interaction with an ECU of the whole vehicle. During the test, the controller sends the actual value below the target value of the accelerator opening degree, and only sends the target value above the target value.
The driver only needs to step on the accelerator to the position of the lower dead point, the accurate positioning of the opening degree of the target accelerator can be realized in the whole process, and the positioning can be carried out for a long time.
In this embodiment, the control chip 11 may adopt a chip having a voltage output function and a chip having a control signal output function in the prior art. The chip is prestored with a preset corresponding relation table which is consistent with the opening of the accelerator pedal and the voltage signal recorded in the tested vehicle type.
