Title:
産業車両の制御装置
Document Type and Number:
Japanese Patent JP5309546
Kind Code:
B2
Abstract:
A control device for an industrial vehicle including an electric storage device, a load device, a hydraulic pump, and a load motor is disclosed. The electric storage device stores regenerative power generated through regenerative braking performed by the travel motor. The hydraulic pump supplies a hydraulic circuit with hydraulic oil to operate the load device. The load motor drives the hydraulic pump. The control device includes a power control unit and a resistance flow passage. The power control unit executes control for supplying the load motor with the regenerative power when the electric storage device is in a fully charged state during regenerative braking performed by the travel motor. The resistance flow passage is arranged in the hydraulic circuit and enables passage of hydraulic oil while applying flow resistance to the hydraulic oil. When the electric storage device is in the fully charged state during regenerative braking performed by the travel motor and, at the same time, the load device is not performing a load handling operation, the hydraulic oil supplied from the hydraulic pump is guided to the resistance flow passage.
