Abstract: The present invention relates to a land vehicle suspension in which a plurality of wheel and hub assemblies (10,11,12,13) are each connected to the body of the vehicle by one of a plurality of actuators (26,27,28,29). The operation of each actuator (26,27,28,29) is controlled by an electronic or electrical processor (100). The processor (100) operates in response to signals received from a plurality of sensors which generate output signals indicative of the attitude of the vehicle body and forces on the body; e.g. a yaw gyrometer (200), a lateral accelerometer (300), a longitudinal accelerometer (400), a steering angle sensor (500), a vehicle speed sensor (600), load cells (45,46,47,48), hub accelerometers (49,50,51,52) and L.V.I.T.'s (53,54,55,56). The processor (100) detects failure of a sensor and a detection of the failure of the sensor operates in response to the remaining functioning sensor or functioning sensors of the plurality of sensors.

Abstract: The tracked vehicle includes a plurality of wheels and a track extending around the wheels. A force sensor is provided for generating a signal indicative of the track force applied to at least one wheel. The track force on a wheel is the force applied to the wheel by the vehicle track due to tensile forces in the track. The force applied on a wheel resulting from the interaction of the wheel with the ground over which the vehicle passes is determined by a force sensor which generates a signal indicative of the force transmitted from the wheel to the vehicle body, a linear variable induction transducer which generates signals indicative of the track force applied to the wheel, and a processor for combining the signals generated by the force sensor and linear variable induction transducer to remove from the signals those signals attributable to the track force applied to the wheel indicative of the force transmitted from the wheel to the vehicle body.
