Abstract
Se provee una disposicion de control para una disposicion de accionamiento/direccion de un vehículo con orugas que tiene una bomba de direccion hidráulicaaccionada a motor que impulsa un motor de direccion hidráulico. La bomba de direccion respondea senales de control de direccion que representan un estado deun volante manejado por un conductor. El motor de direccion provee una entrada a un mecanismo accionador diferencial de orugas que responde al manejo delvolante y acciona las orugasizquier da y derecha para girar el vehículo. La disposicion de control incluye una unidad de control que recibe senales de unsensor de velocidad de motor, velocidad de rotacion del motor de direccion y un sensor de direccion, y las senales decontrol de dire ccion. La unidad decontrol calcula un valor umbral de velocidad del motor en funcion de las senales de velocidad de motor y de control de direccion detectadas, y genera una senalde falla en funcion de la relacion entre la senal develocidad del motor de direccion y un valor umbral de velocidad del motor. La unidad de control genera unasenal una senal de falla de sobrevelocidad cuando la senal de velocidad del motor de direccion es mayor que el valor umbral de velocidad delmotor o menor queun va lor umbral de velocidad de motor negativo, y genera una senal de falla de conflicto de datos cuando la senal de velocidad del motor mínimo negativo omayor que un valor umbral de velocidad de motor mínimo. La unidad de control,cuando el vehículo no e stá siendo comandado para ser girado por las senales decontrol de direccion, genera un valor umbral mínimo, y genera una senal de falla de sobrevelocidad cuando la senal de velocidad del motor es mayor que el valorumbralmínimo o es menor que un valo r umbral mínimo negativo.
