Patent number: 9828028Abstract: When starting automatic pulling-in control, an electronic control unit calculates a temperature increase amount ?Ti of a motor caused by the execution of the automatic pulling-in control and a temperature increase amount ?To of the motor caused by the execution of automatic pulling-out control. Based on the current temperature of the motor, the temperature increase amount ?Ti, and the temperature increase amount ?To, the electronic control unit obtains a predicted temperature of the motor of a case in which the automatic pulling-out control is executed subsequent to the automatic pulling-in control. When the predicted temperature is lower than an allowable upper limit, starting of the automatic pulling-in control is permitted. When the predicted temperature is higher than or equal to the allowable upper limit, starting of the automatic pulling-in control is prohibited.Type: GrantFiled: June 5, 2013Date of Patent: November 28, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hironobu Ishijima, Eriko Yamazaki, Keisuke Oyama, Hisashi Satonaka, Hidehiko Miyoshi, Keisuke Hata

Patent number: 9708003Abstract: When performing automatic control of a steering device that assists a host vehicle to be pulled into or out of a parking space, an electronic control unit performs the following procedure. When there is, as a path for pulling the vehicle into or out of the parking space, a path in which a predicted temperature of the steering device for when the automatic control is performed to move the vehicle along the path would be lower than an allowable upper limit value, the electronic control unit starts the automatic control to move the vehicle along the path. In contrast, when there is no path in which the predicted temperature is lower than the allowable upper limit value, the electronic control unit prohibits the automatic control.Type: GrantFiled: June 26, 2013Date of Patent: July 18, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hironobu Ishijima, Eriko Yamazaki, Keisuke Oyama, Hisashi Satonaka, Hidehiko Miyoshi, Keisuke Hata

Patent number: 9676414Abstract: A parking assistance device assists the operation of steerable wheels for the entry of a vehicle into a parking space by the automatic control of a steering device. Upon execution of the automatic control, an entry path for moving the vehicle to the parking position is calculated, and also, a target steered angle for moving the vehicle along the entry path is calculated, and the actual steered angle is detected. If the target steered angle is an angle closer to the neutral angle than the actual steered angle, then the operation of the steering wheel through the automatic control is stopped. If the target steered angle is not at an angle closer to the neutral angle than the actual steered angle, then the operation of the steering wheel through the automatic control is executed.Type: GrantFiled: May 29, 2013Date of Patent: June 13, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keisuke Oyama, Hironobu Ishijima, Hidehiko Miyoshi, Keisuke Hata

Patent number: 9643602Abstract: A parking support device 1 includes a calculation unit 17 that calculates a speed pattern, an acceleration recognition unit 13 that recognizes driver-requested acceleration, a parking support control unit 19 that performs parking support control in a target parking position based on the speed pattern, and a determination unit 18 that determines whether a host vehicle V can stop in the target parking position at a set deceleration. When the driver-requested acceleration is recognized during the control and exceeds acceleration of the speed pattern at the time of recognition, the parking support control unit 19 accelerates the host vehicle V at the driver-requested acceleration. When the determination unit 18 determines that the host vehicle V can stop in the target parking position at the set deceleration, the host vehicle V is decelerated at the set deceleration and is stopped in the target parking position regardless of the driver-requested acceleration.Type: GrantFiled: June 8, 2015Date of Patent: May 9, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryuji Okamura, Atsushi Sagisaka, Shinya Sannodo, Yu Hiei, Kotaro Saiki, Keisuke Hata

Publication number: 20160068187Abstract: An electronic control unit assists parking of a host vehicle into a parking space. Ultrasonic sensors detect the shape of the side edge of a road and the presence of an obstacle at the road edge. The electronic control unit sets one corner of the obstacle positioned on the side opposite to the road side edge as an originating corner, sets an imaginary line that follows the shape of the road side edge and extends from the originating corner, and recognizes the space between the imaginary line and the road side edge as a parking space. The electronic control unit then determines whether the vehicle can be parked in the recognized parking space.Type: ApplicationFiled: April 26, 2013Publication date: March 10, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keisuke HATA, Hironobu ISHIJIMA, Eriko YAMAZAKI
