APPARATUS FOR CONTROLLING STEERING OF INDUSTRIAL VEHICLE AND METHOD THEREFOR |
| 摘要 |
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. |

1. An apparatus for controlling steering of an industrial vehicle, comprising:
a wheel angle detector configured to detect a wheel angle of a steerable wheel; a travel determining device configured to determine whether or not the industrial vehicle travels at a specified speed or higher; and a control calculation device configured to calculate an average wheel angle and a maximum variation of the wheel angle in a specified period of time and to learn a reference steering limit angle, wherein the control calculation device determines that the steerable wheel is in a steering limit state if an actual traveling speed of the industrial vehicle 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 the wheel angle in the specified period of time is at a specified value or less, and wherein the control calculation device renews the reference steering limit angle if the steerable wheel is determined to be in the steering limit state. |
