<p>Apparatus for controlling a brake system operable using an air supply, includes electronic control means (8) for controlling air distribution and air to electrical conversion means (12) for generating an electrical supply for energising the electronic control means using air under pressure from said air supply (1). Air distribution is controlled either as a result of sensed pressure in a brake control pressure pipe (6) or as a result of an electronic brake control signal.</p> |
