Publication number: 20170349153Abstract: An increase in startup current supplied to a motor is suppressed at an initial stage of starting automatic braking control, while current supply to the motor is performed in a fully energized state after the automatic braking control is started. While output of the motor is increased by controlling the motor in the fully energized state so that a high braking force with high responsiveness is obtained, startup current is prevented from becoming excessive by performing high frequency control only at startup. Thus, decrease in battery voltage is minimized and thus the occurrence of malfunction is minimized in the control systems of various electrical components used in the vehicle.Type: ApplicationFiled: December 17, 2015Publication date: December 7, 2017Inventors: Hironobu YAMASHITA, Takahiro YAMAGUCHI, Kennji FUJIWARA, Takashi MURAYAMA, Keita NAKANO, Aritomo NABETA
