Patent number: 11130522Abstract: A lane departure prevention apparatus includes a driving support ECU configured to perform a lane departure prevention control. The driving support ECU performs the lane departure prevention control with vibrating a steering wheel when determining that a control performing condition becomes satisfied and a traveling lane is straight. The control performing condition becomes satisfied when a vehicle has a high probability of departing from the traveling lane. The driving support ECU performs the lane departure control without vibrating the steering wheel at least in a case where the vehicle has a high probability of departing from the traveling lane toward an outer side of the curved lane.Type: GrantFiled: July 3, 2019Date of Patent: September 28, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takenoshin Takahashi, Masaaki Uechi, Toshinori Esaka, Hidenobu Kinugasa

Patent number: 10232803Abstract: Groove formation portions that define insertion grooves are located in two opposing inner sides of an opening of a main cover. Engagement shafts are located on side portions of the sub-cover that oppose the inner sides. The engagement shafts are insertable into the insertion grooves from an outside and have a thickness that is larger than a groove width of the insertion grooves. The groove formation portions are elastic and deformable to allow insertion of the engagement shafts when the engagement shafts are inserted from the outside. The groove formation portions elastically return to their original forms after insertion of the engagement shafts to engage the engagement shafts and restrict separation of the engagement shafts in a reverse direction. The groove formation portions support the sub-cover to allow the sub-cover to open while engaged with the engagement shafts.Type: GrantFiled: September 15, 2015Date of Patent: March 19, 2019Assignees: Toyota Shatai Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Hiroaki Ichihara, Nobuyoshi Imaeda, Shuuichi Satou, Masaaki Uechi, Hideaki Hayashi, Atsutoshi Sakaguchi

Patent number: 10124776Abstract: A brake control device includes: an object detector; and an ECU configured to (a) determine, based on an output of the object detector, whether a predetermined condition that there is a possibility that the vehicle collides with the object, is satisfied; (b) apply an automatic brake when it is determined that the predetermined condition is satisfied; and (c) stop applying the automatic brake when an operation amount of an accelerator operation unit of the vehicle becomes equal to or larger than a predetermined threshold. The ECU also continues applying the automatic brake when a specified condition including a condition that an operation amount of a brake operation unit of the vehicle is larger than a predetermined amount is satisfied even when it has been determined that the operation amount of the accelerator operation unit becomes equal to or larger than the predetermined threshold.Type: GrantFiled: September 28, 2016Date of Patent: November 13, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Masaaki Uechi

Patent number: 9566971Abstract: In a hydraulic brake system including a cylinder device that includes a front chamber and a rear chamber located on front and rear sides of a pressurizing piston, respectively, presence or absence of liquid leakage from a brake line is detected based on a hydraulic pressure in the rear chamber. Where a state in which a subtraction value obtained by subtracting an actual rear hydraulic pressure from a target rear hydraulic pressure is larger than a first malfunction determination threshold value has continued for a time not shorter than a first malfunction determination time, and then an increase of the actual rear hydraulic pressure at a rate not lower than a set rate has caused the subtraction value to become smaller than a return determination threshold value, it is determined that the pressurizing piston has been bottomed due to liquid leakage from the front chamber.Type: GrantFiled: October 25, 2011Date of Patent: February 14, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takahiro Okano, Yusuke Kamiya, Kiyoyuki Uchida, Akira Sakai, Hiroshi Ueno, Masaaki Uechi

Patent number: 9440648Abstract: When a pedestrian or the like in an area that is ahead in the direction of movement of a vehicle travelling on a road and is adjacent to the road is moving in an direction to cross the road, a system ECU varies the time of execution of a safety operation for ensuring the safety of the pedestrian in accordance with a road condition in the area where the pedestrian or the like is present. Specifically, the time of execution of the safety operation is delayed in the order of a first road condition, in which the area in which the pedestrian is present is not in a roadway, a second road condition, in which the area is in a roadway and not in an opposing traffic lane, and a third road condition, in which the area is in a roadway and in an opposing traffic lane.Type: GrantFiled: October 30, 2012Date of Patent: September 13, 2016Assignee: Toyota Jidosha Kabushiki KaishaInventor: Masaaki Uechi
