Abstract

A method for controlling an industrial truck equipped with a vehicle radio unit via a radio control unit that is portable and designed to transmit signals to the vehicle radio unit, which has a transmitter, a housing equipped with at least one control panel and an acceleration sensor arranged in the housing, wherein the method comprises the following steps:
Detecting a momentum transfer to the control panel when an acceleration is captured entirely or partially in one direction, Forwarding the detected momentum transfer as a signal to the transmitter of the radio control unit and Transmitting the forwarded signal by the transmitter to the vehicle radio unit.

First claim

The invention claimed is:

1. A method for controlling an industrial truck equipped with a vehicle radio unit using a portable radio unit, the method comprising:
detecting, using an acceleration sensor, a momentum transfer to a control panel of a radio control unit, wherein the acceleration sensor has at least one measurement axis in a direction of which an acceleration can be captured;
generating a signal from the acceleration sensor in response to the detected momentum transfer;
sending the signal to a transmitter of the portable radio control unit; and
transmitting the signal by the transmitter to a vehicle control unit,
wherein the momentum transfer to the control panel is detected when at least one of the amplitude of the acceleration changes its sign, the amplitude of the acceleration in at least one direction of the measurement axis exceeds a first predetermined value, the amplitude in a normal direction of the control panel exceeds a second predetermined value, and the amplitude in the normal direction of the control panel exceeds the second predetermined minimum value and the amplitude in at least one other direction does not exceed a third predetermined minimum value.

2. The method according to claim 1 , wherein an assigned individual signal is transmitted to the vehicle radio unit when an individual momentum transfer to the control panel is detected.

3. The method according to claim 1 , wherein an assigned double signal is transmitted to the vehicle radio unit when two momentum transfers to the control panel which are separated by less than a predetermined time span are detected.

4. The method according to claim 1 , wherein an assigned triple signal or a signal of higher order is transmitted to the vehicle radio unit when three or more momentum transfers to the control panel are detected, and wherein a temporal separation of which does not respectively exceed a specified minimum time span.

5. The method according to claim 1 , wherein signals received by the vehicle radio unit are forwarded to a vehicle controller.
