Abstract

Disposicion de control de direccion para un vehículo de oruga que incluye una bomba de direccion de desplazamiento variable impulsada a motor. El motorimpulsa un mecanismo de accionamiento diferencial que acciona las ruedas de accionamiento deoruga izquierda y derecha. Una unidad de control electronico,en funcion de la posicion del volante, la velocidad del vehículo, la velocidad del motor, la direccion del vehículo marcha adelante/marcha atrás y otrosparámetros, genera una senal decoma ndo que controla la placa oscilante de la bomba de direccion. El sistema opera de modo que, para una posicion dada delvolante, una curvatura de giro del vehículo disminuye a medida que aumenta la velocidad del vehículo, donde la curvaturade giro es inversamente proporcionala un radio de giro. Esto se logra calculando un valor de velocidad de giro igual a la velocidad del vehículo multiplicado por una relacion de unavelocidad nominal del motor dividido por la velocidad de motordetectad a, y calculando la senal de comando igual a un valor de ganancia de direccionmultiplicado por una relacion del valor de velocidad de giro dividido por un valor de velocidad nominal del vehículo.
