- the connecting device has a separate sensor reset for taking the angle of rotation sensor into the zero position.
- the separate sensor return spring is of particular importance. Due to the rough driving of the heavy vehicles, it is possible that the sensor element can come loose from the pedal unit. As a result, it is no longer possible to reset the sensor element with the two return springs to the zero position via the connecting device. If the sensor return spring did not exist, the corresponding output signals, such as PWM signals, analog signals, switch signals and the like, would be generated in the same size as were output in the last pedal position.

- An E 2 PROM is a read-only memory that can be used like a read-write memory. This makes it possible to update or change the data entered in the E 2 PROM.
- the pedal element can open a floor angle in relation to the base plate element in the idle position.
- the floor angle minus the pedal angle can then be equal to an end position angle.
- the floor angle can be 30 °, 35 ° or 40 ° and the end position angle 8 °, 13 ° or 23 °, so that this results in the pedal angle of 22 ° already specified. gives. This makes it possible for the pedal to move in the pedal angle above the floor and to be easy to operate.

- D4 then ensures that the counter clock signal GEZ according to FIG. 11 b is delivered.
- a rotation angle sensor is used, which the signals already described according to Fig. 7 issues. These signals are transmitted to the engine control unit and used accordingly to control the engine. It is particularly advantageous that the very small actuation angle of only 22 ° is placed in the linear sections of the ASIC output voltage U A. This ensures that the PWM signals, the analog signals, the switch signals GT and the mutually connected signals GE1 and GE2 are reproduced exactly. Even the very rough operation on the accelerator pedal of heavy motor vehicles does not cause any misbehavior.
- reprogrammable units such as. B. ASICs and microprocessor units can be adjusted with the aid of the PIN programming via the flat plugs 38 of the angle of rotation sensor. This makes it possible to adjust and set each sensor so that it emits the desired signals.
