1. Apparatus for controlling a land vehicle, comprising:

  • a programmable controller including stored therein data representative of a reference model of the vehicle'"'"'s performance, said data including vehicle tractive efficiency data which includes parameters on traction characteristics of a vehicle having a chosen wheel and tire combination when moving on a selected land surface;

    a slave controller operatively connectable to each of a plurality of controllable sub-systems of a said vehicle, and operatively connected to the programmable controller;

    one or more sensors, operatively connected to the programmable controller, for detecting the performance of said controllable sub-systems; and

    a comparator for comparing the detected performance of the said controllable sub-systems and the reference model, the controller being operable to control the said sub-systems in dependence on an output of the comparator, characterised in that the reference model is a steady-state model, whereby to permit co-ordinated, automated control of all the said sub-systems.
