Abstract
An apparatus and a method for controlling steering of an industrial vehicle includes a wheel angle detector, a travel determining device, and a control calculation device that calculates a wheel angle average and a maximum variation of wheel angle in the specified period and learns a reference steering limit angle. The control calculation device determines that the steerable wheel is in a steering limit state if an actual traveling speed is maintained at the specified speed or higher for the specified period of time or longer, the average wheel angle in the specified period of time is at a specified angle or greater, and the maximum variation of wheel angle in the specified period of time is at a specified value or less. The control calculation device renews the reference steering limit angle if the steerable wheel is determined to be in the steering limit state.
