Publication number: 20240109534Abstract: A vehicle driving assistance apparatus executes a braking assistance control to forcibly stop an own vehicle when there is a probability that the own vehicle collides with an object, and executes a stopped-state keeping control to keep the own vehicle stopped when the own vehicle is stopped by the braking assistance control. The apparatus executes the stopped-state keeping control for a standard time when the own vehicle is stopped at a place in an area other than a termination recommendation area in which an execution of the stopped-state keeping control is recommended to be terminated. The apparatus executes the stopped-state keeping control for a time shorter than the standard time when the own vehicle is stopped at a place in the termination recommendation area.Type: ApplicationFiled: July 3, 2023Publication date: April 4, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenichi SHIMIZU, Takashi HASEGAWA, Yuma HOSHIKAWA

Patent number: 11932265Abstract: A driving assistance system for a vehicle that includes a target sensor, an operation amount sensor, a speed sensor, and an electronic control unit configured to perform pre-collision control when a predetermined control start condition is satisfied. Also, the pre-collision control is not performed, even when the predetermined control start condition is satisfied, when a permission condition has not been established by a point in time at which the predetermined control start condition is satisfied.Type: GrantFiled: November 23, 2021Date of Patent: March 19, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Wataru Ike, Yuma Hoshikawa

Patent number: 11834072Abstract: A driving assist apparatus executes an autonomous braking control when a predetermined autonomous stop condition becomes satisfied, executes a stopped state keeping control to keep the own vehicle stopped after stopping the own vehicle by the autonomous braking control, and terminates executing the stopped state keeping control when a predetermined stopped state keeping termination condition becomes satisfied while executing the stopped state keeping control. The driving assist apparatus executes a driving force limitation control to limit a driving force generated to move the own vehicle to a value smaller than the driving force which depends on an amount of operating the acceleration pedal when determining that the predetermined stopped state keeping termination condition is satisfied, and a mistaken pressing operation occurs. The mistaken pressing operation is an operation performed by a driver to mistakenly press an acceleration pedal with an intention to press a brake pedal.Type: GrantFiled: September 29, 2020Date of Patent: December 5, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuto Shimbo, Yuma Hoshikawa, Toshifumi Kawasaki, Ryota Murakami

Patent number: 11731621Abstract: When a collision avoidance target is a pedestrian or a bicycle, a driving assistance ECU performs automatic braking control. In this case, accelerator override cannot be performed. When the collision avoidance target is an automobile and when an accelerator operation amount is equal to or larger than a first operation amount threshold, the driving assistance ECU prohibits the automatic braking control. In this case, the accelerator override can be performed. When the accelerator operation amount is smaller than the first operation amount threshold, the driving assistance ECU performs the automatic braking control.Type: GrantFiled: May 20, 2022Date of Patent: August 22, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Wataru Ike, Yuma Hoshikawa, Ryota Murakami, Yuto Shimbo

Patent number: 11370431Abstract: A vehicle control device comprises an operation amount sensor for measuring an operation amount of an accelerator element, an object sensor for detecting an object ahead of a vehicle, and a controller for applying a normal operation drive force which is determined depending on the operation amount to the vehicle. The controller executes an adaptive cruise control for applying a drive force required for an acceleration of the vehicle to become equal to an adaptive cruise control acceleration to the vehicle. The adaptive cruise control acceleration is an acceleration which increases as a difference between an inter-vehicle distance from the vehicle to an objective-forward-vehicle and a target inter-vehicle distance increases. When an erroneous operation start condition becomes satisfied, the controller ends the adaptive cruise control, and executes an erroneous operation related control for applying a drive force which is smaller than the normal operation drive force to the vehicle.Type: GrantFiled: March 23, 2020Date of Patent: June 28, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuto Shimbo, Yuma Hoshikawa

Patent number: 11305762Abstract: A driving assistance apparatus comprising a first object detecting sensor device, a second object detecting sensor device, and a control unit. The first object detecting sensor device detects an object and obtains the position and a certainty value of the object. The second object detecting sensor device detects an object and obtains the position and an object type for the object. The control unit executes collision avoidance control to avoid collision between a vehicle and a monitoring target object which is detected by the first object detecting sensor device when the certainty value of the monitoring target object is higher than a certainty threshold. If the monitoring target object is also detected by the second object detecting sensor device and its object type is a specific type, the certainty threshold is made larger.Type: GrantFiled: March 18, 2020Date of Patent: April 19, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuya Ikuta, Yuma Hoshikawa

Patent number: 10829128Abstract: A pre-collision control ECU performs a pre-collision control in order to preventing a collision between the own vehicle and the object when a control start condition is satisfied. The ECU acquires a velocity threshold Vsth corresponding to a region in which the own vehicle travels based on information to specify the region. When an allowance condition has been satisfied before a timing at which the control start condition is satisfied, the ECU performs the pre-collision control. When the allowance condition has not been satisfied before the timing, the ECU does not perform the pre-collision control. The allowance condition is a condition that an accelerator operation amount is equal to or greater than an operation amount threshold and a vehicle velocity is equal to or lower than the acquired velocity threshold.Type: GrantFiled: September 24, 2018Date of Patent: November 10, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuma Hoshikawa, Wataru Ike
