Abstract

[Problem] Provided is a motor regenerative control method that performs regenerative control without creating an adaptive map value.[Solution] The invention relates to a motor regenerative control method that allows a negative current to flow to a motor such that a regenerative current flows to a battery to charge the battery. The motor regenerative control method includes: setting a target regenerative current value based on a state of the battery; allowing the negative current to flow to the motor such that the regenerative current is close to the target regenerative current value and measuring the regenerative current while allowing the regenerative current to flow to the battery; performing feedback control to allow the negative current to flow to the motor so as to eliminate a difference between a regenerative current value and the target regenerative current value; determining whether the regenerative current value is increasing or decreasing; maintaining the feedback control when it is determined that the regenerative current value is increasing; and when it is determined that the regenerative current value is not capable of reaching the target regenerative current value and is decreasing, detecting a maximum regenerative current value based on a history of the regenerative current value and adjusting and controlling the current flowing to the motor such that the regenerative current value reaches the maximum regenerative current value.
