Patent number: 8527149Abstract: In a passenger protection device, an object detection unit detects a relative position of an object in a circumference of a vehicle to the vehicle. A side collision prediction unit predicts that the object is about to collide with a side face of the vehicle, based on the relative position detected by the object detection unit. An impact detection unit detects an impact of the object on the vehicle side face. A side collision judgment unit determines whether the object has collided with the vehicle side face, based on the impact detected by the impact detection unit. A passenger protection unit protects a passenger in the vehicle. When the side collision prediction unit predicts that the object is about to collide with the vehicle side face and the side collision judgment unit determines that the object has collided with the vehicle side face, the passenger protection unit is initiated.Type: GrantFiled: February 7, 2007Date of Patent: September 3, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Motomi Iyoda

Patent number: 7986151Abstract: When moving a head rest front portion in a full-open position direction, an ECU determines that the head rest front portion comes close to an occupant head portion on the basis of a detection result of an electrostatic capacitance sensor so as to stop the head rest front portion, and determines that the head rest front portion comes close to the occupant head portion on the basis of an absolute capacitance change with respect to a reference electrostatic capacitance value of the electrostatic capacitance sensor. Alternatively, the ECU determines that the head rest front portion comes close to the occupant head portion on the basis of a change amount of the electrostatic capacitance value of the electrostatic capacitance sensor.Type: GrantFiled: November 10, 2006Date of Patent: July 26, 2011Assignees: Aisin Seiki Kabushiki Kaisha, Toyota Jidosha Kabushiki Kaisha, Toyota Boshoku Kabushiki KaishaInventors: Koichi Hirota, Koji Aoki, Manabu Tsuruta, Kiyoka Matsubayashi, Motomi Iyoda, Tatsuhiro Okawa, Fumitoshi Akaike

Patent number: 7911374Abstract: A target position is estimated in such a manner to maintain target position continuity, with high accuracy, even when the X coordinate displacement of the target is large. On a scan in which the target position is not detected, when a trajectory of the target in the past is within a predetermined region in the vicinity of the Y-axis, a position for estimate is a position having an X coordinate resulting from shifting, by a first displacement, the X coordinate estimated according to the trajectory, on a basis of the X coordinate of a previous position, while when the trajectory is not within the predetermined region, the position for estimate is a position having an X coordinate resulting from shifting, by a second displacement that is larger than the first displacement, the X coordinate estimated according to the trajectory, on a basis of the X coordinate of a previous position.Type: GrantFiled: January 26, 2009Date of Patent: March 22, 2011Assignee: Fujitsu Ten LimitedInventors: Takumi Moriuchi, Masahiro Sakaguchi, Hisateru Asanuma, Tomoya Kawasaki, Jun Tsunekawa, Motomi Iyoda
