Hybrid industrial vehicle
DRIVE
June 8, 2011
A hybrid industrial vehicle including an engine (11), generator motor (12), battery (13), and a travel motor (14). A first generated power computation unit (19) computes a deceleration rate based required generated power based on the travel power and charge power of the battery (13). A second generated power computation unit (19) computes an actual power based required generated power based on used power used by the travel motor (14) and the charge power of the battery (13). A generated power control unit controls the generator motor (12) so that the generated power of the generator motor (12) becomes equal to a total generated power determined from the deceleration rate based required generated power and actual power based required generated power. An engine rotation speed control unit (19) controls rotation speed of the engine (11) to be greater than or equal to a required cargo handling engine rotation speed.
