Publication number: 20150006049Abstract: A vehicle control device is applied to a vehicle having a driving mechanism for transmitting a driving force to a plurality of wheels, a braking mechanism having an electronic parking brake for generating a parking brake force for at least one of the plurality of wheels, and a coupling state control mechanism for controlling state of coupling of the plurality of wheels. The vehicle control device determines whether the electronic parking brake is in a lock stuck state in which the parking brake force cannot be canceled. When at least one of the plurality of wheels is in the lock stuck state, the vehicle control device exercises stuck state special control to loosen or cancel state of coupling between a wheel determined to be in the lock stuck state and a wheel determined to be not in the lock stuck state by controlling the coupling state control mechanism.Type: ApplicationFiled: February 1, 2013Publication date: January 1, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takashi Watanabe, Shinsuke Yamamoto

Publication number: 20140200784Abstract: Each of a plurality of electric brake devices corresponds to one of a plurality of wheels and includes a motor. A brake ECU, which controls the electric brake devices, determines whether there is an overheated motor of which the temperature T is greater than or equal to a first set threshold value Tth1. Also, when there is only one overheated motor, the brake ECU reduces a current value Ix for the overheated motor at a more gradual gradient in the case where the temperature T of the overheated motor is low than in the case where the temperature is high.Type: ApplicationFiled: September 28, 2012Publication date: July 17, 2014Applicant: ADVICS CO., LTD.Inventors: Shun Nohira, Naoki Yabusaki, Shinsuke Yamamoto

Patent number: 8744643Abstract: A vehicle controller which can perform appropriate control even when an acceleration sensor is mounted in a movable portion of a vehicle. The vehicle controller includes an acceleration sensor attached to a cabin movable around a shaft, an open/closed state detection section which detects the open/closed state of the cabin, and a correction section which corrects the output value of the acceleration sensor. When the open/closed state detection section detects that the cabin is opened and then closed, the correction section performs correction. When the acceleration sensor is provided in the cabin serving as a movable portion, the inclination of the acceleration sensor may differ slightly before and after the cabin is opened.Type: GrantFiled: May 18, 2009Date of Patent: June 3, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventor: Shinsuke Yamamoto

Patent number: 8498802Abstract: In a vehicle drive control apparatus, a behavior determination unit determines whether a vehicle behavior is in a stable state or an unstable state based on a vehicle turning behavior. An engine stop control unit avoids stopping the engine as automatic stop conditions are not satisfied when the vehicle behavior is determined to be in an unstable state during operation of the engine. When the vehicle behavior is in a stable state and other automatic stop conditions are satisfied during operation of the engine, the engine stop control unit stops the engine. During stability control performed by a stability ECU, the engine stop control unit avoids stopping the engine as the automatic stop conditions are not satisfied.Type: GrantFiled: December 14, 2010Date of Patent: July 30, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Shinsuke Yamamoto

A plurality of tubular protrusion portions project from the rail body in a substantially vertical direction relative to an axial direction of the rail body, and are arranged at a predetermined interval in the axial direction. A tubular extension portion extends from each of the protrusion portions in a substantially vertical direction relative to both an axial direction of the protrusion portions and the axial direction of the rail body. The tubular extension portion is inserted into a bore which extends from an exterior of an internal combustion engine to a combustion chamber.

Publication number: 20120285777Abstract: A vehicle brake apparatus capable of preventing abnormal vibration due to thickness variations in a disc rotor includes a motor drive unit configured to control the motor which presses the brake pad against the disc rotor, a brake pressure detection unit for detecting a braking pressure for pressing the brake pad, and a wheel speed sensor for detecting a rotation speed of the disc rotor. If an amount of variation in the detection values detected by the brake pressure detection unit during one rotation of the disc rotor exceeds a variation amount determination threshold value and a detection value variation frequency has a correlation with the rotation speed of the disc rotor and the detection value variation frequency exceeds a variation frequency determination threshold value, the motor drive unit controls the motor in inverted phase to the variation in the detection values.Type: ApplicationFiled: February 24, 2011Publication date: November 15, 2012Applicant: ADVICS CO., LTDInventors: Yusuke Oshio, Takahisa Yokoyama, Akira Sakai, Naoki Yabusaki, Shinsuke Yamamoto

A vehicle controller includes an acceleration sensor attached to a cabin movable around a shaft, an open/closed state detection section which detects the open/closed state of the cabin, and a correction section which corrects the output value of the acceleration sensor. When the open/closed state detection section detects that the cabin is opened and then closed, the correction section performs correction. When the acceleration sensor is provided in the cabin serving as a movable portion, the inclination of the acceleration sensor may differ slightly before and after the cabin is opened. For this reason, when correction is constantly performed, a useless operation is performed, causing an increase in a control load.Type: ApplicationFiled: May 18, 2009Publication date: March 15, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Shinsuke Yamamoto

The fixed core has a fixed axial end on a side of the movable core. The movable core has a movable axial end on a side of the fixed core. At least one of the fixed axial end and the movable axial end has at least one recession. The at least one of the fixed axial end and the movable axial end, which has the at least one recession, has an outer circumferential periphery and an inner circumferential periphery.

Patent number: 7712686Abstract: A fuel injection valve includes a valve member for regulating a flow of a fuel to a nozzle hole, a movable core axially slidable in an integrated body with the valve member, a fixed core being faced by an end of the movable core, and a coil portion having an increasing number of winding of a winding wire toward the movable core in a bobbin to have a magnetic attractive force between the movable core and the fixed core upon application of an electric current. The number of winding wire increases toward an end on a movable core side in the coil portion. Therefore, the generated magnetic field increases on the movable core side. In this manner, the magnetic attractive force between the fixed core and the movable core is increased without increasing a cross-section and/or a body of the movable core.Type: GrantFiled: August 10, 2005Date of Patent: May 11, 2010Assignee: Denso CorporationInventor: Shinsuke Yamamoto
