VEHICLE STEERING CONTROL DEVICE AND METHOD

摘要

The present invention has an object to contribute to realizing a steering control device for imparting a steering reactive force to a steering wheel. To this end, a steering control device for a forklift is provided which obtains a command steering reactive force according to a wheel angle on the basis of a wheel angle detected by a wheel angle sensor (41) and table data (60) representing the correlation between the wheel angle and the command steering reactive force, and which controls an electric-control brake (31) so as to make the steering reactive force equal to the command steering reactive force. The steering control device: obtains a correction coefficient (± 1 ) and the like according to vehicle state amounts on the basis of the vehicle state amounts (such as the wheel angle deviation (”¸)) other than the wheel angle, which are detected by vehicle state amount detecting means (such as a steering wheel angle sensor (23)), and table data (52) and the like representing the correlation between the vehicle state amounts and the correction coefficients; corrects the table data (60) by using the correction coefficients (sets an inclination (±)) ; obtains a command steering reactive force according to the wheel angle on the basis of the table data (60) and the wheel angle; and controls the electric-control brake (31) so as to make the steering reactive force equal to the command steering reactive force.
