Abstract

The present invention relates to an industrial truck control system (10) for influencing the driving operation of an industrial truck (A, B) according to irregularities along the route to be traveled by the industrial truck (A, B), the system comprising a sensor device (14) for recording irregularities along the route in assignment to the position of irregularities concerned, a memory device (16) for storing the data recorded by the sensor device, and means (16) for influencing the driving operation of the industrial truck (A, B) in dependence on the respective position of the industrial truck (A, B) and according to the data of the sensor device (14) stored in the memory device (16).

Claims

1. An industrial truck control system for influencing the driving operation of an industrial truck according to one or more irregularities having positions along a route to be traveled by the industrial truck, comprising:

one or more sensors configured to identify at least one of said irregularities and record data regarding the position of said irregularity;

a memory device for storing the data recorded by the one or more sensors;

a controller adapted to influence the driving operation of the industrial truck based on a position of the industrial truck and the stored data regarding the position of said irregularity; and

a microprocessor configured to determine a time for maintenance of the industrial truck according to the stored data.

2. Industrial truck control system according to claim 1, wherein the microprocessor is further configured to determine the time for maintenance of the industrial truck based on the frequency with which the industrial truck passes the position of said irregularity.

3. A method for indicating maintenance time intervals of an industrial truck based on one or more irregularities having positions along a route to be traveled by the industrial truck, comprising the steps of:

identifying at least one of said irregularities and recording data indicating the position of said irregularity;

storing said data in a memory device;

determining a time for maintenance of the industrial truck according to the stored data; and

indicating the time determined for the maintenance of the industrial truck.

4. System for determining maintenance time intervals of an industrial truck according to one or more irregularities having positions along a route to be traveled by the industrial truck, comprising:

a sensor device configured to identify at least one of said irregularities and record data indicating the position of said irregularity on the route,

a memory device for storing data recorded by the sensor device, and

a microprocessor configured to determine a time for the next maintenance of the industrial truck according to the stored data.

5. The system of claim 4, wherein the configuration is such that said time for the maintenance of the truck is determined according to the frequency with which the industrial truck passes the position of said irregularity.
