ELECTRIC DRIVING TYPE UTILITY VEHICLE HAVING REGENERATIVE BRAKE FORCE DISTRIBUTION CONTROL FUNCTION, AND REGENERATIVE BRAKE FORCE DISTRIBUTION CONTROL METHOD THEREOF

摘要

An electric driving type utility vehicle having a regenerative brake force distribution control function, and a regenerative brake force distribution control method thereof are provided. The utility vehicle includes: a controller for controlling an output and a recovery of a motor; recovery sensing means for sensing a recovery braking state when the motor is driven; a power measurement unit for measuring the amount of recovery power generated in the recovery braking state; and a power switching unit for automatically switching a drive mode from a two-wheel drive mode to a four-wheel drive mode or vice versa according to the load condition. The present invention can switch the present mode to the four-wheel drive mode by operating the power switching unit according to the control of the controller when sensing the recovery brake through the recovery sensing means in the driving state.
