ELECTRICAL SYSTEM
Technical performance parameters
1. Permissible pedal pressure in the working direction: <
500 N (400N①).
2. Allowable force perpendicular to the rotation plane: <
200 N
3. Allowable force in the opposite direction of work: <
200 N.
4. The spring reset time at -40℃ : ≤ 3 s②.
5. The spring reset time at -18℃ : ≤ 1 s②.
6. Minimum pedal rebound force: ≥ 5N.
① 400N is suitable for projects with external mechanical
stops.
② To ensure that one of the two springs can meet the
requirements.
7. Electric-displacement characteristics of electronic
accelerator pedal (see A in the left fi gure)
Working conditions:
Permissible operating temperature: -40℃ ~+85℃.
Storage condition: dust-free.
Temperature: -30℃ ~ +60℃.
Fault diagnosis
ECU for a variety of sensors, actuators, and power
amplifier and detection circuits monitoring, when the
electronic accelerator pedal has a fault, the vehicle may
not exist method acceleration, abnormal engine speed
and other phenomena, commonly used fault code see
the total fault table:
Electronic accelerator pedal fault inspection:
◆ Check that the connector is well connected
◆ Check whether the wire harness and accelerator
pedal pins are bent and deformed
◆ Measure the voltage of pin 1 and pin 2
◆ Measure the voltage of pin 4 and pin 6
◆ Measure the on-off of all stitching wire harness ends
