Patent number: 10059209Abstract: A converter is capable of using two power sources located on a first side by switching connection of the two power sources between series connection and parallel connection. Under certain conditions, such as when a detected atmospheric pressure is lower than a predetermined value, frequency of use of the two power sources in series connection is reduced in the converter. It is thereby possible to prevent generation of excessive voltage by the power converter.Type: GrantFiled: June 15, 2015Date of Patent: August 28, 2018Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshiya Hashimoto, Noritake Mitsutani, Kenji Yamada

Patent number: 9902390Abstract: When the accelerator and the brake pedal are simultaneously depressed, braking occurs with drive force being produced. This increases the amount of heat produced by a friction braking device. Therefore, when the accelerator and the brake pedal are simultaneously depressed (S100: Yes), the range of use for a regenerative braking device is increased by expanding the regenerative braking limit (S101), thereby decreasing the range of use for the friction braking device, so that the produced heat to be suppressed. As a result, it is possible to simplify the friction braking device and eliminate the need to install a cooling mechanism equipped a high cooling performance.Type: GrantFiled: December 9, 2011Date of Patent: February 27, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshiya Hashimoto, Hideaki Yaguchi

Patent number: 9725007Abstract: An electric vehicle includes a voltage converter, a temperature sensor, and a control unit. The voltage converter performs bidirectional voltage conversion between an output electric path and one or both of first and second batteries, while allowing switching of an operating mode between a serial operating mode in which the first and second batteries are connected in series relative to the output electric path, and a parallel operating mode in which the first and second batteries are connected in parallel.
