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. |

1. An electrically driven utility vehicle having a regenerative braking force distribution control function,
wherein the electrically driven utility vehicle is a utility vehicle that moves by driving a motor using, electric energy as a power source and comprises: a controller for controlling an output of the motor and regeneration, regenerative detection means for detecting a regenerative braking state while driving the motor, a power measurement unit for measuring an amount of regenerative power generated in the regenerative braking state, and a power switching unit for automatically changing a drive mode from a two-wheel to a four-wheel or from the four-wheel to the two-wheel according to a road surface condition, wherein when the regenerative braking state is detected through the regenerative detection means while driving, and a current drive mode is the two-wheel drive mode, the power switching unit operates by the controller and switches to the four-wheel drive mode, and wherein the regenerative detection means is a counter electromotive force relay driven by counter electromotive force (induced electromotive force) of the motor that is generated when the regenerative braking is generated. |
