Patent number: 8341804Abstract: A grommet is provided which can reduce an insertion load without decreasing a disengagement load of an inserting member. The inserting member, having a leg portion and a head portion formed by increasing the diameter of a tip end of the leg portion, is inserted from one end side of a body portion of the grommet into an insertion hole and attached to an inserted member with the grommet interposed. On the one end side from a groove portion formed in an outer circumferential surface of the body portion, a diameter of the insertion hole is equal to or larger than a diameter of the head portion. On the other end side from the groove portion, the grommet has a small diameter portion in which a diameter of the insertion hole is smaller than the diameter of the head portion and is equal to or larger than a diameter of the leg portion.Type: GrantFiled: December 19, 2008Date of Patent: January 1, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kinya Yoshii, Fumimori Imaeda

Patent number: 7583052Abstract: In a vehicle having a motor as the drive power source, a fuel cell and battery are on board as the power source for the motor. A target output value for the fuel cell is set within a range such that fuel cell output can track change in power demand. The battery is charged/discharged so as to compensate for delay in fuel cell output relative to power demand. By setting a higher target output value the lower the remaining charge in the battery, the fuel cell can be utilized efficiently while ensuring good output responsiveness.Type: GrantFiled: June 8, 2007Date of Patent: September 1, 2009Assignee: Toyota Jidosha Kabushiki KaishaInventor: Kinya Yoshii

Patent number: 6126251Abstract: A brake controlling apparatus for electric vehicles provided with a transmission between an electric motor and wheels. Regenerative brake control furnishes a regenerative braking force to the vehicle. A transmission control switches a stage of gear of the transmission the basis of driver operation. A friction brake control furnishes a friction braking force to the vehicle by controlling a friction brake. During gear shifting control, the regenerative brake control sets a regenerative torque essentially to zero, and the friction brake control supplements the regenerative braking force that was furnished to the vehicle prior to gear shifting control with the friction braking force. Therefore, there is no drop in deceleration during gear shifting control, even if the driver downshifts during regenerative braking. Smooth gear shifting is then possible.Type: GrantFiled: May 4, 1998Date of Patent: October 3, 2000Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kinya Yoshii, Eiji Ichioka, Takeharu Koide
