DESCRIPTION:The work described is part of a programme aimed at the creatio
 n of the best possible virtual driver. The programme is supported by Willi
 ams F1. \nPrevious research on the application of optimal linear preview c
 ontrol theory to driving road vehicles with only modest excursions from a 
 straight-running equilibrium state is extended into the general large-late
 ral-motion arena. Optimal controls are found for steady-cornering trim sta
 tes of an exemplary but simple car at a given speed as a function of corne
 ring effort\, up to the practical limit. \nThe manner in which the optimal
  controls change as the cornering vigour changes is discussed. Simulations
  of the virtual driver-controlled car are shown to demonstrate the closed-
  loop system following lateral path demands and the advantages of employin
 g gain-scheduled adaptive control over a fixed control scheme are demonstr
 ated. Combined longitudinal and lateral control by optimal use of preview 
 information will be mentioned.\n\nProfessor Sharp is a Visiting Professor 
 in the School of Engineering at the University of Surrey. The project also
  involves Mark Thommyppillai\, research student\, and Dr Simos Evangelou (
 Cambridge Engineering Graduate) both of the Departments of Electrical and 
 Electronic and Mechanical Engineering at Imperial College London.\n
