Title:
REGENERATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/217726
Kind Code:
A1
Abstract:
The regeneration control device for a motor (2) on which regeneration control can be performed is provided with: a weight estimation unit (51) for calculating an estimated weight (Wes) on the basis of information obtained by traveling; a regenerative torque characteristic storage unit (52) for prestoring regenerative torque characteristics that specify the optimum regenerative torque (TOPT) of the motor (2) for a traveling state; and a regenerative torque control unit (53) for obtaining the optimum regenerative torque (TOPT) from the regenerative torque characteristics on the basis of an accelerator opening (Ac) and controlling the motor (2) to the optimum regenerative torque (TOPT). The regenerative torque characteristic storage unit (52) stores a regenerative torque weak map (Mw) and a regenerative torque strong map (Ms) which are each selected depending on whether the estimated weight (Wes) is less than a threshold value (WTh) or not. The regenerative torque control unit (53) controls the motor (2) on the basis of the regenerative torque weak map (Mw) until the weight estimation unit (51) calculates the estimated weight (Wes).
