Patent number: 10661779Abstract: A control system for a hybrid vehicle configured to generate a required power continuously even if a large power is required frequently. An operating mode of the hybrid vehicle is selected from HV mode and EV mode, and in the hybrid vehicle, a drive power established by generating maximum output power of the engine is smaller than a drive power established by supplying a maximum electric power to the motor from the electric storage device. A controller is configured to shift the operating mode from the EV mode to the HV mode when an SOC level of a battery falls below a threshold level, and to raise the threshold level when a required running condition in the electric vehicle mode is a condition that cannot be achieved by the engine without operating the motor given that the hybrid vehicle is propelled in the hybrid mode.Type: GrantFiled: October 9, 2018Date of Patent: May 26, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tadashi Fujiyoshi, Junichi Deguchi, Akihiro Fujimoto, Hideki Kubonoya

Patent number: 10351122Abstract: A vehicle control apparatus includes an electronic control unit. The electronic control unit is configured to perform feedback control of a motor such that a torque is output for stopping a crankshaft at a target angle. A first angle is used as the target angle during a first period from start of the feedback control to first detection of rotation of the crankshaft in a negative rotational direction for returning the crank angle. A second angle is used as the target angle during a second period from the lapse of the first period to detection of a changeover in a rotational direction of the crankshaft from the negative to a positive rotational direction. The electronic control unit is configured to return the target angle to the first angle at a first timing after the lapse of the second period.Type: GrantFiled: March 31, 2017Date of Patent: July 16, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akihiro Fujimoto, Wan Leng Ang, Yu Miyahara, Yuji Iwase
