Patent number: 10569646Abstract: A fuel cell vehicle includes tanks configured to store a fuel gas to be supplied to the fuel cell, the tanks being respectively disposed in front of and behind the motor drive unit such that a longitudinal direction of each of the tanks corresponds to a width direction of the fuel cell vehicle. The tanks are disposed such that respective end portions of the tanks on a side on which the high-voltage wiring portion is positioned are outside the high-voltage wiring portion in the width direction of the fuel cell vehicle and the respective end portions of tanks overlap a tire-wheel assembly in a front-rear direction of the fuel cell vehicle.Type: GrantFiled: January 18, 2018Date of Patent: February 25, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Nobuhito Mori, Masanori Miyakawa, Keijiro Ohshima, Daiki Nishiumi

Patent number: 10300788Abstract: A vehicle includes an electrical device in which a high-voltage part is disposed within a case, and a fuel tank. The high-voltage part is disposed near a first side end of the case in a vehicle width direction. The fuel tank has a first end portion in the vehicle width direction and a second end portion opposite to the first end portion. When a collision load equal to or greater than a predetermined value is applied to the fuel tank from the outside in a vehicle front-rear direction, the fuel tank is configured to be horizontally rotated about the first end portion of the fuel tank, and the second end portion of the fuel tank is configured to contact the second side end of the electrical device.Type: GrantFiled: February 27, 2018Date of Patent: May 28, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daiki Nishiumi, Masanori Miyakawa, Keijiro Ohshima, Nobuhito Mori

Patent number: 7609012Abstract: In an automatic transmission position control by a motor, it is determined whether the present instant belongs to a starting period, that is, the present instant is immediately after resetting of a control unit or application of power to it. If it is the starting period, an actual shift position that is detected from an output of an output shaft sensor for detecting a rotation position of a motor is set as an instructed shift position. With this measure, even if the control unit is reset for a certain reason while the vehicle is running, the instructed shift position is not changed in association with the resetting. This prevents trouble that the shift position is switched contrary to the intention of the driver, whereby the reliability of a position switching control can be increased.Type: GrantFiled: April 4, 2007Date of Patent: October 27, 2009Assignees: DENSO Corporation, Toyota Jidosha Kabushiki KaishaInventors: Shigeru Kamio, Kenichi Fujiki, Sumiko Amamiya, Keijiro Ohshima, Yasushi Kobiki, Yuji Inoue
