Abstract: A control method and mechanization is disclosed to bleed compressor air in order to control the gas turbine of a turbo heater. Compressed air may selectively bleed with a control value in order to increase or decrease the efficiency of the gas turbine unit. Additionally, the control system enables the bleed air system allows to re-circulate compressed air to mix with the combustion air and provide a pre-heat thereof. The control system further enables re-direction of the combustion feed stream into the exhaust gas stream to promote complete combustion of the unburned fuel and combustion by-products in a catalytic converter downstream of the gas turbine to provide a breathable exhaust gas from the turbo heater.

Abstract: Master cylinder pressure of either or both of the primary and secondary braking circuits is sensed by a pressure sensor or sensors mounted in a manifold which is installed directly on a brake pressure modulator housing when the modulator is manufactured. The pressure sensors receive power and are grounded through the electronic control unit which is an integral component of the modulator; accordingly, the sensors do not require external electrical connections other than those already provided on the modulator. Since the sensing manifold is installed and tested for leaks when the modulator is manufactured and before the modulator is shipped to the vehicle assembly plant, assembly operations in addition to those required in installation of the modulator in the vehicle braking system are not required.

Abstract: In a vehicle with first and second front vehicle wheels and third and fourth rear vehicle wheels and at least one member of a first group comprising anti-lock brake control and positive acceleration traction control, a brake control method comprising the steps of: determining a desired vehicle yaw rate; determining an actual vehicle yaw rate; responsive to the desired and actual vehicle yaw rates, determining an axle command; responsive to the desired and actual vehicle yaw rates, determining a torque command; applying the axle command during activation of one of the anti-lock brake control and the positive acceleration traction control to one member of a second group comprising (i) the two front wheels and (ii) the two rear wheels, wherein wheel-to-road traction is increased and a difference between desired vehicle yaw rate and actual vehicle yaw rate is minimized; and applying the torque command to at least one of the vehicle wheels independently of the axle command to create a yaw torque moment on the vehi

Abstract: A comprehensive diagnostic for an active brake control system for automatically increasing braking at selected wheels of an automotive vehicle in response to detected vehicle turning maneuvers provides a hierarchy of diagnostic procedures for diagnosing local transducer and transducer circuit fault conditions, for diagnosing lack of correlation between transducers and subsystems, and for diagnosing low system level performance. Transducers or subsystems are isolated and indicated as the source of diagnosed low system performance to facilitate fault treatment procedures. Active brake control system authority is automatically reduced for at least the duration of diagnosed fault conditions.

Abstract: A vehicle yaw rate control method comprising the steps of: first estimating vehicle yaw rate responsive to a first set of criteria; second estimating vehicle yaw rate responsive to a second set of criteria, wherein the first set of criteria includes a first vehicle condition not included in the second set of criteria and wherein the second set of criteria includes a second vehicle condition not included in the first set of criteria; measuring vehicle yaw rate using a yaw rate sensor; and indicating a reverse travel condition if both of the first and second estimates have signs opposite to a sign of the measured vehicle yaw rate.
