Patent number: 9638096Abstract: A vehicle is equipped with an internal combustion engine having a forced-induction apparatus with variable boost pressure, a first motor generator for generating electricity while applying negative torque to the engine, and a battery for storing the electricity generated by the first motor generator. During the operation of the engine, a target boost pressure is set lower as the rotational speed of the first motor generator is increased. The engine is controlled such that, with the boost pressure adjusted to the target boost pressure, the output torque of the engine has a required value determined by the accelerator operation amount. Further, while the output torque of the engine is adjusted to the required value, the magnitude of the negative torque by the first motor generator acting on the engine is adjusted such that the engine rotational speed has a target value.Type: GrantFiled: April 25, 2012Date of Patent: May 2, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Kamijo, Keisuke Morisaki

Patent number: 8674637Abstract: A vehicle includes a power storage device, a motor generator, a converter for stepping up an output voltage from the power storage device, an inverter for driving the motor generator, and an ECU. The inverter includes switching elements. The switching elements have a characteristic that the withstand voltage of the switching elements decreases as the temperature of the inverter decreases. The ECU sets the stepped-up voltage, based on a temperature characteristic of the power storage device and a temperature characteristic of the inverter, so that the stepped-up voltage is increased within a range in which the stepped-up voltage does not exceed the withstand voltage. In this way, at low temperatures, deterioration of the power performance can be suppressed while the switching elements are protected.Type: GrantFiled: May 19, 2010Date of Patent: March 18, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventor: Yusuke Kamijo
