Abstract

Disposicion de accionamiento/direccion para un vehículo con orugas. Se provee una disposicion de control para una disposicion de accionamiento/direccion deun vehículo con orugas que tiene una bomba de direccion hidráulica accionada a motor queimpuls a un motor de direccion hidráulico. La bomba de direccionresponde a senales de control de direccion que representan un estado de un volante manejado por un conductor. El motor de direccion provee una entrada a unmecanismo accionadordiferencial de or ugas que responde al manejo del volante y acciona las orugas izquierda y derecha para girar el vehículo. La disposicionde control incluye una unidad de control que recibe senales de un sensor de velocidad de motor, velocidad derotacion del motor de direccion y un sensor dedireccion, y las senales de control de direccion. La unidad de control, cuando las senales de control de direccion indican que el volante está siendo girado enuna direccion opuesta a una direccion derotacion del motor de dire ccion, generan y guardan un primer valor de relacion que representa una relacion de lavelocidad del motor a la velocidad de la bomba. Entonces, si la senal de control de direccion no cambia después de cierta duracion detiempo, la unidad decontrol ge nera y guarda un segundo valor de relacion que representa una relacion posterior de velocidad de motor a velocidad de bomba. La unidad de controlcalcula entonces un valor de diferencia que representa una relacionposterior de velocidad de motor a vel ocidad de bomba. La unidad de control calcula entoncesun valor de diferencia que representa una diferencia entre los valores de relacion primero y segundo, y genera una senal de falla si el valor dediferenciatiene una magnitud que es menor que una m agnitud predeterminada. Así, el sistema de control genera una senal de falla cuando las senales detectadas indican quela posicion de la placa oscilante de la bomba no está cambiando como debería enrespuesta a cambios en la posicion del volante.
