Patent number: 6826469Abstract: A vehicle traveling control system includes a control mode for controlling a vehicle speed by applying braking force so as to maintain the vehicle speed at a predetermined driving force threshold vehicle speed or smaller than that while a predetermined driving force beyond a creeping torque has been applied. The applied driving force is reduced when a target braking force required for maintaining the vehicle speed at the predetermined upper threshold vehicle speed or smaller than that is equal to a first predetermined value or greater than that. The applied driving force is increased when the target braking force or the actual braking force becomes a second predetermined value or smaller than that during the applied driving force being reduced.Type: GrantFiled: January 10, 2003Date of Patent: November 30, 2004Assignee: Aisin Seiki Kabushiki KaishaInventors: Yoshifumi Iwata, Yuu Tanaka, Katsuhiko Iwazaki, Hisashi Satonaka, Mitsuhiko Morita, Tomohiko Endo, Seiji Kawakami, Hiroaki Kataoka

Patent number: 6814860Abstract: An oil strainer comprises upper and lower partial bodies, made of synthetic resin, joined together to form a roughly tube-shaped strainer main body, the interior of which is provided with a filter. The oil strainer has a flange section for attachment with bolts, and the flange section is provided with at least one bolt hole which passes through the interior of the roughly tube-shaped strainer main body. With this structure, it is possible to provide an oil strainer which can be installed on a small installation surface, which is able to reduce resin fatigue, and which can prevent impairment of the seal due to loosening of installation members.Type: GrantFiled: June 3, 2002Date of Patent: November 9, 2004Assignee: GP Daikyo CorporationInventors: Yoshifumi Iwata, Yoshihiro Takemoto, Yasumi Mototani

Patent number: 6796802Abstract: An electrical connection box 20 is arranged rearward of and in the vicinity of a dash panel 13, and is fixed to a cowl side panel 15 via mounting members 23, 24 extended from a box body 21. The box body 21 of the electrical connection box 20 is formed with a protruding member 22 for receiving impact from the dash panel 13 before the box body 21 does upon collision of the vehicle. The mounting members 23, 24 are formed to have such a rigidity as to allow the members 23, 24 to be broken to prevent the box body 21 from being crushed when the protruding member 22 receives impact, and load exceeding a predetermined limit is applied to the box body 21. The breakage of the electrical connection box upon collision of the vehicle is thereby minimized.Type: GrantFiled: November 16, 2001Date of Patent: September 28, 2004Assignee: Yazaki CorporationInventor: Yoshifumi Iwata

Patent number: 6778891Abstract: A parking assistance device capable of performing an easy operation for parking a driver's own vehicle along a parking course up to a parking target position. A parking course in which the driver's own vehicle reaches a parking target position indicated by a marker of a screen of a display of the driver's own vehicle is calculated up (S16). If a steering operation of the driver's own vehicle is performed, in the case that the current rudder angle changes towards a target rudder angle in order to move the driver's own vehicle along a parking course, the steering assistant power of the driver's own vehicle is increased (S21) and thus the steering operation of the driver's own vehicle is performed by a relatively small operational power.Type: GrantFiled: September 27, 2002Date of Patent: August 17, 2004Assignee: Aisin Seiki Kabushiki KaishaInventors: Yuu Tanaka, Yoshifumi Iwata, Toshiyasu Katsuno

Publication number: 20030151526Abstract: A parking assist device (1) includes a camera (3) for capturing an image of an exterior of a vehicle, and a monitor (4) for displaying the captured image, and sets a target parking position by moving a target parking frame (11) displayed on a screen of the monitor (4). A default position of the target parking frame (11) is determined based on a target parking position (P2) which is a relative position with respect to a parking preparation position (P1). The target parking position (P2) is estimated based on a running state of the vehicle until the vehicle reaches the parking preparation position (P1).Type: ApplicationFiled: January 10, 2003Publication date: August 14, 2003Inventors: Yuu Tanaka, Yoshifumi Iwata, Tomohiko Endo, Hisashi Satonaka, Mitsuhiko Morita, Seiji Kawakami, Katsuhiko Iwazaki, Hiroaki Kataoka

Publication number: 20030150661Abstract: In a parking assist apparatus that assists with moving, by automatic steering, a vehicle from an arbitrary stopping position to a target parking position set by the driver, a setting portion (i.e., a parking assist ECU) sets both a path from the stopping position to the target parking position and a steering operation necessary to bring the vehicle along that path. When this path cannot be set with the steering angle in the stopping position set as the initial steering angle, and when the path can be set with another steering angle as the initial steering angle, an instruction portion (i.e., a monitor or a speaker) instructs the driver to turn the steering wheel to this other steering angle.Type: ApplicationFiled: January 6, 2003Publication date: August 14, 2003Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroaki Kataoka, Hisashi Satonaka, Seiji Kawakami, Mitsuhiko Morita, Tomohiko Endo, Katsuhiko Iwazaki, Yoshifumi Iwata, Yuu Tanaka

Patent number: 6600658Abstract: The electrical junction box has a case, which accommodates a printed circuit board provided in a lower side of the case. The case also receives an electrical wiring circuit and a busbar circuit disposed in an upper side of the case so as to be parallel to the printed circuit board. Wiring harness connectors are mounted on a side wall of the case, and relay connectors are positioned on the side wall or another side wall of the case. The side walls are perpendicular to the printed circuit board. The wiring harness connectors are connected to inner circuits including the printed circuit, the busbar circuit, and the electrical wiring circuit. The case has a top cover, a bottom cover, and a horizontal intermediate partition. The intermediate partition is provided with the electrical wire circuit on an under surface of the partition so as to be opposed to the printed circuit. The upper surface of the intermediate partition is provided with the busbar circuit.Type: GrantFiled: March 21, 2002Date of Patent: July 29, 2003Assignee: Yazaki CorporationInventor: Yoshifumi Iwata

A parking course in which the driver's own vehicle reaches a parking target position indicated by a marker of a screen of a display of the driver's own vehicle is calculated up (S16). If a steering operation of the driver's own vehicle is performed, in the case that the current rudder angle changes towards a target rudder angle in order to move the driver's own vehicle along a parking course, the steering assistant power of the driver's own vehicle is increased (S21) and thus the steering operation of the driver's own vehicle is performed by a relatively small operational power. On the other hand, if the current rudder angle changes away from the target rudder angle, the steering operation of the driver's own vehicle is performed by a relatively large operational power since the rudder supplementary power is decreased (S21).Type: ApplicationFiled: September 27, 2002Publication date: April 24, 2003Inventors: Yuu Tanaka, Yoshifumi Iwata, Toshiyasu Katsuno

Patent number: 6487481Abstract: A parking assisting apparatus displays an image of a rear view from a vehicle, which is acquired by a camera, on a display located in a passenger compartment, thus assisting in a parking procedure. The parking procedure assisted by the parking assisting apparatus is, for example, a parallel parking procedure in which the rotating direction of the steering wheel must be switched. An assumed path along which the vehicle is moved during the parking procedure is determined in accordance with the steering angle of the steering wheel when the parking procedure is started. In the parking procedure, the display indicates a steering information that informs the driver of a timing at which the rotating direction of the steering wheel must be switched, in accordance with the assumed path.Type: GrantFiled: May 30, 2001Date of Patent: November 26, 2002Assignees: Aisin Seiki Kabushiki Kaisha, Toyoda Jidoshakabushiki KaishaInventors: Yuu Tanaka, Toshiaki Kakinami, Yoshifumi Iwata, Kazushi Konno, Toshiyasu Katsuno, Yuichi Kubota, Osamu Okazaki
