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: 9604638Abstract: A parking assist system includes an electronic control unit. The electronic control unit is configured to detect an obstacle. The electronic control unit is configured to determine whether a vehicle is allowed to run over the obstacle. The electronic control unit is configured to, when it is determined that the vehicle is allowed to run over the obstacle, set a target position, to which the vehicle moves, to a position at which the vehicle overlaps with the obstacle.Type: GrantFiled: September 10, 2015Date of Patent: March 28, 2017Assignees: AISIN SEIKI KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Kiyokawa, Masaya Kato, Tomohisa Yamashita, Tomoyuki Matsuba, Hironobu Ishijima, Keisuke Oyama

Publication number: 20160101813Abstract: 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: ApplicationFiled: June 5, 2013Publication date: April 14, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hironobu ISHIJIMA, Eriko YAMAZAKI, Keisuke OYAMA, Hisashi SATONAKA, Hidehiko MIYOSHI, Keisuke HATA

Publication number: 20160075374Abstract: A park exit assist system includes an electronic control unit. The electronic control unit is configured to detect a situation around a host vehicle parked or stopped in a parking/stopping area on a roadside. The electronic control unit is configured to calculate, on the basis of a detected result of the situation around the host vehicle, a park exit guidance path along which the host vehicle is moved out of the parking/stopping area to a traffic road and in which a steering angle becomes neutral at the time when a roadside front end of the host vehicle advances into the traffic road. The electronic control unit is configured to guide the host vehicle from the parking/stopping area toward the traffic road by at least executing steering control along the park exit guidance path.Type: ApplicationFiled: September 10, 2015Publication date: March 17, 2016Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN SEIKI KABUSHIKI KAISHAInventors: Tomohisa YAMASHITA, Masaya KATO, Hiroyuki TACHIBANA, Motokatsu TOMOZAWA, Motonari OBAYASHI, Hironobu ISHIJIMA, Keisuke OYAMA
