Abstract
A system for automatically adjusting the height of a vehicle wherein a polarity-determination pattern detector and an allowable-displacement pattern detector are disposed in confronting relation to and movable relative to a pattern plate in parallel directions in response to variations in the height of a vehicle. The pattern plate has a polarity-determination pattern having one end positioned in confronting relation to the polarity-determination pattern detector and extending in a direction of movement of the pattern plate, and an allowable-displacement pattern having a center thereof positioned in confronting relation to the allowable-displacement pattern detector and extending in the direction of movement of the pattern plate. The pattern plate may be provided with a plurality of such polarity-determination and allowable-displacement patterns. An electrical circuit generates a signal indicative of an increase or decrease in the vehicle height depending on whether or not there is an output signal from the polarity-determination pattern detector when there is no output signal from the allowable-displacement pattern detector for a predetermined interval of time. With such an arrangement, the vehicle height can automatically be adjusted even while the vehicle is running.
