Abstract
A mobile vehicle comprising a shiftable transmission with fixed gear ratio steps and a controllable friction clutch contains a distance sensor, which is connected to an inch pedal and in which the starting position and the end position of the inch pedal are adjusted by an electronic control unit and allocated to an inch effect from 0% to 100%. Due to the electronic adjusting process of the inch pedal path via the inch effect and the service brake, the intersecting time between the service brake and the actuating force of the clutch can be adjusted. The driving comfort of the vehicle is increased and the risk of damage to the multi-disk clutch is reduced.
Claims6
A mobile vehicle comprising:
- a shiftable transmission with fixed gear ratio steps, which contains a friction clutch that can be engaged by an actuating force,
- an inch pedal, a pedal path of which is detected by a distance sensor, and supplied to an electronic control unit, upon actuation of the inch pedal, the electronic control unit lowers the actuating force of the friction clutch as a function of the pedal path and then brings the friction clutch into a slipping state,
- a starting position and an end position of the inch pedal are detected by the electronic control device, and allocated to an inch characteristic line, wherein:
- at vehicle start-up the starting position and the end position of the inch pedal are allocated in the electronic control unit to the characteristic line of a 0% and 100% inch effect to eliminate mechanical adjustment of the distance sensor.

- and
- wherein the electronic control unit determines the function of the pedal path at which a service brake is activated and the vehicle is braked, a braking time is determined by measuring a motion change of the vehicle and stored in the electronic control unit.
