Title:
BRAKE FOR ELECTRIC MOTOR VEHICLE
Document Type and Number:
Japanese Patent JP3307120
Kind Code:
B2
Abstract:
PURPOSE: To eliminate continuation of the mechanical vibration of a motor without vibrating regenerative torque even if the detected number of rotations of the motor is fluctuated by the vibration of the motor when the number of rotations of the motor reaches close to zero as a result of regenerative brake.
CONSTITUTION: When the number of rotation s N of a motor becomes lower than Nk0 indicating an extremely slow speed range (104), power converting operation by an inverter is stopped (126). Thereafter, until the set time is counted by an inverter stop timer (122), the power converting operation is subsequently inhibited (128). When the set time is elapsed (122) or an accelerator pedal is pressed (118), the power converting operation of the inverter becomes executable (114). When the accelerator pedal is pressed (118), a regenerative torque command TK is forcibly set to 0 (130).
