Abstract
A steering method for an industrial truck includes manually steering at least one steerable wheel, detecting an angular position of the at least one steerable wheel, and motor-steering at least one additional steerable wheel as a function of the detected angular position. For a 90° change of a travel direction of the industrial truck, the method comprises steering the at least one steerable wheel and the at least one additional wheel by 90°, manually steering the at least one additional wheel, and motor-steering the at least one steerable wheel.

A steering method for an industrial truck, the steering method comprising:
- manually steering at least one steerable wheel;
- detecting an angular position of the at least one steerable wheel;
- and
- motor-steering at least one additional steerable wheel as a function of the detected angular position,
- wherein, for a 90° change of a travel direction of the industrial truck, the method comprises:
- steering the at least one steerable wheel and the at least one additional wheel by 90°;
- manually steering the at least one additional wheel;
- and
- motor-steering the at least one steerable wheel.
A steering system for an industrial truck, the steering system comprising:
- a steering unit;
- at least one manually steerable first wheel;
- a first steering motor configured to steer the at least one manually steerable first wheel;
- a steering control device configured to generate a steering angle reference value;
- at least one steering angle sensor configured to detect a steering angle of the at least one manually steerable first wheel, the at least one steering angle sensor being connected to work together with the steering control device;
- at least one additional steerable motor-steered second wheel comprising a steering motor, the steering motor being configured to be driven as a function of the steering angle reference value generated by the steering control device;
- a second steering motor, wherein the at least one additional steerable motor-steered second wheel is connected to work together with the second steering motor;
- and
- a switch-over device, wherein the switch-over device is configured to switch between a connection of the steering unit with the first steering motor and a connection of the steering unit with the second steering motor.
