Specifications and characteristic curve
The characteristic curve is for an accelerator-pedal module with a kickdown switch.
| Index | Explanation |
|---|---|
| 1 | Sensor voltage (V) |
| 2 | Sensor 1 voltage at idle |
| 3 | Sensor 2 voltage at idle |
| 4 | Sensor 1 output signal curve |
| 5 | Sensor 2 output signal curve |
| 6 | Characteristic curve for rising pedal force |
| 7 | Characteristic curve for decreasing pedal force (releasing the pedal) |
| 8 | Increased pedal force for kickdown and decreased pedal force at end of kickdown |
| 9 | WOT position without kickdown |
| 10 | Kickdown OFF |
| 11 | Kickdown ON |
| 12 | Pedal angle in degrees (°) |
| 13 | Pedal force in newtons (N) |
Start of kickdown phase: The detent position at which increased pedal force is required lies between a maximum of 13.8° and a minimum of 1.6° before the mechanical travel stop. On the characteristic curve, the threshold value for kickdown ON must be immediately after the point for maximum pedal force for initiating kickdown.
End of kickdown phase: The final position for increased pedal force occurs 1.6° before the mechanical travel stop at the earliest and 13.8° before it is reached at the latest. On the characteristic curve for decreasing pedal force the threshold value for kickdown OFF must be immediately after the point for maximum pedal force.
Voltage values: The signal data for the two sensors are a percentage of the voltage supply. Sensor 1: At idle the value is 15 % of the supply voltage, at the travel stop it is roughly 90 %. Sensor 2: At idle the value is 7.5 % of the supply voltage, and roughly 45% at the travel stop.
Note the following specifications for the accelerator-pedal module:
| Size | Value |
|---|---|
| Voltage range | 4.5 to 5.5 V |
| Maximum power consumption | 15 mA |
| Temperature range | -40 to 80 °C |
