    摘要： A steering control device obtains a command steering reactive force according to a wheel angle based on a wheel angle and table data representing the correlation between the wheel angle and the command steering reactive force, and which controls an electric-control brake to make the steering reactive force equal to the command steering reactive force. The steering control device: obtains a correction coefficient according to vehicle state amounts based on the vehicle state amounts other than the wheel angle, which are detected by vehicle state amount detecting means, and table data representing the correlation between the vehicle state amounts and the correction coefficients; corrects the table data by using the correction coefficients; obtains a command steering reactive force according to the wheel angle based on the table data and the wheel angle; and controls the electric-control brake to make the steering reactive force equal to the command steering reactive force.

    摘要： An energy recovering system in a hydraulic lift device of a battery operated industrial truck. With the system, working oil can be supplied to other hydraulic actuators while energy recovering operation is performed by the hydraulic lift device, occurrence of pressure pulsation in the working oil can be prevented, and energy recovering efficiency is increased. The hydraulic lift device comprises a lift cylinder (1) for lifting a fork F, an electric motor (4) rotated by power supply from a battery (5), a hydraulic pump (3) for supplying pressurized oil to the lift cylinder (1), a control valve (14) disposed in a pressurized oil supply path (23), and a controller (17). The controller (17) controls the opening of the control valve (14) and rotation speed of the electric motor (4) which functions as an electric generator driven by the hydraulic pump (3) rotated by the action of the pressurized oil returning from the lift cylinder (1) when a load is lowered so that the generated electricity charges the battery (5) to recover the potential energy of the load.
