Further, the gears 18 include a forward gear, a reverse gear, and a stop gear.

Further, the signal exchanging switch 13 exchanges the encoder feedback signal.

Further, the brightness of the indicator light C7 changes due to the change of the speed of the accelerator 1.

The operation method comprises the following steps:

plug A2 is connected with a vehicle controller encoder, plug B6 is connected with a motor encoder plug, plug C8 is connected with a vehicle controller plug, and plug D9 is connected with a vehicle operation system plug.

1) Turning on the vehicle key switch 19:

observe whether voltmeter a15 has a voltage display:

if the voltmeter A15 has voltage, the display is normal;

if the voltmeter A15 does not display the voltage, whether the connecting line of the storage battery is disconnected or virtual-connected needs to be checked; detecting whether the circuit from the battery to the key switch 19 has the conditions of disconnection and virtual connection; detecting whether the key switch 19 is good for use or not and whether a passage can be formed or not; and detecting whether the circuit of the key switch 19 back controller is disconnected or virtual.

Observe whether indicator light D10, indicator light E11 are on:

if the indicator light D10 and the indicator light E11 are both on, the operation is normal;

if the indicator light D10 is not on, the output voltage module of the encoder in the controller is damaged, and the controller is recommended to be repaired or replaced.

If the indicator light E11 is not on, the output voltage module of the accelerator 1 in the controller is damaged, and the controller is recommended to be repaired or replaced.

2) Slowly rotate the drive wheel, observe pilot lamp A3, pilot lamp B5 and whether flash in turn:

if the indicator light A3 and the indicator light B5 alternately flicker, the operation is normal;

if the situation that the indicating lamp A3 and the indicating lamp B5 are simultaneously turned on or off, the indicating lamp A3 is normally turned on, the indicating lamp B5 is not turned on, the indicating lamp B5 is normally turned on, the indicating lamp A3 is not turned on and the like belongs to the damage of the encoder, the replacement of the encoder is recommended.

3) The accelerator 1 pedal is lightly stepped to see whether or not there is a change in the indicator lights F12 and C7:

if the indicator lamp F12 is on after the accelerator 1 pedal is lightly stepped, the signal of the accelerator 1 acceleration switch is proved to be normal; continuously and deeply stepping on the accelerator 1 pedal, gradually increasing the brightness of the indicator lamp C7, slowly releasing the accelerator 1 pedal, and gradually reducing the brightness of the indicator lamp C7, so that the acceleration signal of the accelerator 1 is proved to be normal;

if the indicator lamp F12 is turned on and the indicator lamp C7 is not turned on, or the indicator lamp F12 is turned off and the indicator lamp C7 is turned on, or the indicator lamp F12 and the indicator lamp C7 are not turned on, the accelerator 1 is proved to be damaged, and the accelerator 1 is recommended to be replaced.

4) Engage shifter 18 into forward gear, observe voltmeter C17 bright and display the same voltage as voltmeter a 15:

if the voltmeter C17 is bright and shows that the voltage is normal as the same as the voltmeter A15;

if the voltmeter C17 is not bright or the display voltage is lower than that of the voltmeter A15, whether the gear shift 18 is used well or not and whether a passage can be formed or not is checked; checking whether the plug and the line of the gear device 18 are oxidized, fallen off and connected in a virtual way or not;

shift position device 18 is engaged in reverse, watch voltmeter B16 is lit and displays the same voltage as voltmeter a 15:

if the voltmeter B16 is bright and shows that the voltage is normal as the same as the voltmeter A15;

if voltmeter B16 is not bright or shows that the voltage is lower than voltmeter A15, checking whether gearshift 18 is good for use or not and whether a passage can be formed or not; checking whether the plug and the line of the gear device 18 have oxidation, falling and virtual connection conditions;

no matter the gear shifter 18 is in a forward gear or a reverse gear, only one of the voltmeter B16 and the voltmeter C17 is lightened and displays the same voltage as that of the voltmeter A15, and if the voltmeter B16 and the voltmeter C17 are lightened simultaneously, the conditions of adhesion and short circuit of a circuit behind the gear shifter 18 are proved, so that the problem that the vehicle cannot be operated is not solved.

5) The encoder ab signal changeover switch 13 uses:

the signal exchange switch 13 is used for exchanging the sequence of the A B signal fed back by the encoder after the controller is replaced, the switch is normally switched to a 'backward' gear, if the vehicle cannot move after the controller is replaced, the switch is switched to the 'backward' gear when the A B signal needs to be exchanged, and the A B signal is exchanged on the original basis (the vehicle is in a state of closing the main power supply during operation).
