Abstract
An industrial truck having a lighting device, a logistics system having multiple industrial trucks as well as methods for operating the lighting device as well as the logistics system. The industrial truck includes at least one vehicle light and a controller for actuating the vehicle light. The controller is configured to capture at least one vehicle state parameter and to actuate the vehicle light in a pattern based on the at least one vehicle state parameter.
Claims18
An industrial truck comprising:
- at least one vehicle light;
- and
- a controller comprising hardware configured to actuate the at least one vehicle light, wherein the controller is configured to capture at least one vehicle state parameter and to actuate the at least one vehicle light in a pattern based on the at least one vehicle state parameter;
- wherein the controller is further configured to capture a proximity signal and, in response to a successful capturing of the proximity signal, to activate an actuation of the at least one vehicle light;
- the vehicle state parameter is linked to multiple authorization categories and the proximity signal comprises an item of information relating to an authorization category, and
- the controller is further configured, in response to a successful capturing of the proximity signal, to compare the authorization category of the vehicle state parameter and the authorization category of the proximity signal and to actuate the at least one vehicle light as a function of the comparison.

A logistics system comprising:
- at least one charging unit;
- and
- an electrically driven industrial truck comprising:
- at least one vehicle light;
- and
- a controller comprising hardware configured to actuate the at least one vehicle light, wherein the controller is configured to capture at least one state parameter of the charging unit and to actuate the at least one vehicle light in a pattern based on the at least one state parameter of the charging unit.
3 more elements
A logistics system comprising:
- a comparison controller;
- a first industrial truck comprising:
- at least one first vehicle light;
- and
- a first controller comprising hardware configured to actuate the at least one first vehicle light, wherein the first controller is configured to capture at least one first internal vehicle state parameter and to actuate the at least one first vehicle light in a first pattern based on the at least one first internal vehicle state parameter;
- and
- a second industrial truck comprising:
- at least one second vehicle light;
- and
- a second controller comprising hardware configured to actuate the at least one second vehicle light, wherein the second controller is configured to capture at least one second internal vehicle state parameter and to actuate the at least one second vehicle light in a second pattern based on the at least one second internal vehicle state parameter;
- wherein the first controller is configured to transmit the at least one first internal vehicle state parameter to the comparison controller and the second controller is configured to transmit the at least one second internal vehicle state parameter to the comparison controller,
- the comparison controller is configured to compare the at least one first internal vehicle state parameter and the at least one second internal vehicle state parameter with one another, to produce a comparison result and to generate a first control signal and a second control signal,
- the first control signal characterizes a ratio of the at least one first internal vehicle state parameter to the comparison result and the second control signal characterizes a ratio of the at least one second internal vehicle state parameter to the comparison result,
- the comparison controller is further configured to transmit the first control signal to the first controller and to transmit the second control signal to the second controller unit, and
- the first controller unit is configured to actuate the at least one first vehicle light in the first pattern based on the first control signal and the second controller is configured to actuate the at least one second vehicle light in the second pattern based on the second control signal.
12 more elements
A method for operating a lighting device of an industrial truck, the method comprising:
- capturing at least one vehicle state parameter;
- and
- actuating the at least one vehicle light of the industrial truck in a pattern based on the at least one vehicle state parameter;
- wherein the vehicle state parameter is an internal vehicle state parameter and the method further comprises:
- capturing the internal vehicle state parameter and at least one vehicle state parameter of at least one further industrial truck as at least one external vehicle state parameter,
- comparing the internal vehicle state parameter and the at least one external vehicle state parameter with one another;
- and
- actuating the at least one vehicle light in a pattern based on the comparison.
