TRAVELING CONTROLLER FOR INDUSTRIAL VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide the traveling controller for an industrial vehicle for protecting a battery discharge power limit value without performing excessive acceleration limiting.

SOLUTION: A traveling controller includes: a rotational frequency command value calculation part 32 for calculating a traveling motor rotational frequency command value on the basis of an acceleration opening; an acceleration command reference value calculation part 33 for calculating an acceleration command reference value on the basis of a traveling motor actual rotational frequency and the traveling motor rotational frequency command value; an acceleration limit value calculation part 35 for calculating an acceleration limit value for limiting an acceleration command value to a range that prevents a battery discharge power limit value from being exceeded on the basis of information including the traveling motor actual rotational frequency and the power generation motor power and the battery discharge power limit value; and an acceleration command value determination part 36 for selecting one of the acceleration command reference value and the acceleration limit value which is smaller as an acceleration command value, and for transmitting the acceleration command value to a traveling motor driving control part 27.
