Abstract
To prevent sudden and violent control swings in the guidance system of vehicles which are guided in a guide path by sensing an electrical or magnetic field derived from a guide track conductor, which sensed field is evaluated in a servo steering system to maintain a transducer at a given distance from the conductor, a limiter stage is provided to which the steering command signal is applied to limit the command signal to predetermine swings; preferably, a low pass filter is also connected to the transducer output to have the command signal applied thereto, the output of the low pass filter being connected to the limiter stage to permit wide, gradual control swings of the servo system while inhibiting wide, rapid swings.
