Wheeled vehicle steering system

A wheeled vehicle steering system comprising:

• adjustable steering means;
• means for generating a first electrical signal proportional to the demanded input of the steering input means;
• means for steering a vehicle wheel in response to said first electrical signal;
• sensing means for detecting the response of the vehicle;
• means for producing a second electrical signal proportional to said detected response;
• wherein the means for steering the vehicle wheel in response to said first electrical signal comprises:
• an input filter for filtering the first electrical signal;.
• comparator means for comparing the filtered first electrical signal and the second electrical signal and for producing a difference signal from comparison of the filtered first electrical signal and the second electrical signal;
• and
• means for steering the first vehicle wheel in response to said difference signal.
