This paper reviews two aspects of lateral control: the magnetic field distributions associated with a guideway-based, wire-reference configuration and the associated vehicle-based sensors. Two wire-reference schemes have thus far been suggested. In the first, the amplitude characteristics of the magnetic field are used to obtain the lateral control signal. The resulting problems, which involve amplitude distortions of the field due to the proximity of steel-reinforcing materials, are defined, and their effects on vehcile control (poor tracking and passenger discomfort) are discussed. In the second approach, the lateral control signal is primarily dependent on the phase characteristics of the magnetic field. A theoretical analysis and a corresponding experimental field study indicated that the problems associated with the first approach were largely overcome, as evidenced by successful fullscale tests of an automatically steered vehicle.
