Steering control
HCB-SCB (Steering Control Basic)

The steering control provides a universal steering system for an axle with two wheels. Several control units can communicate with each other via CAN bus, so that up to 4 axles can be controlled.

The steering setpoint can be specified via incremental rotary encoders (electronic steering wheel), absolute rotary encoders (set value from front axle or drawbar), via joystick or via digital inputs.

Possible extended functions

• Steering with the Ackermann algorithm, in which all wheels are positioned tangentially around the center of a circle
• Crab steering, in which all wheels are adjusted in parallel to move the vehicle sideways
• Lane-following functions in which all wheels use the same lane to drive gently on the ground
• Speed-dependent limitation of the steering angle
• Switchable steering: front axle only or rear axle only

Inputs and outputs

• Digital inputs, parameterizable as release, Ackermann algorithm, crab steering, track following, straight ahead, direction reversal
• Frequency input for the driving speed (alternatively via CAN bus)
• Frequency inputs that are evaluated as rotary encoders for a steering wheel (with rotary encoder output)
• Analog inputs for target steering angle, actual steering angle left, actual steering angle right
• Proportional outputs with current feedback measurement for controlling the steering cylinders
• Status outputs, can alternatively be used to display errors, end stop left or right, straight ahead position
