Publication number: 20150375740Abstract: 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: ApplicationFiled: June 8, 2015Publication date: December 31, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryuji OKAMURA, Atsushi SAGISAKA, Shinya SANNODO, Yu HIEI, Kotaro SAIKI, Keisuke HATA

Patent number: 8958929Abstract: In a vehicle control apparatus which performs a remote operation of a vehicle using a remote control, a remote operation of the vehicle which is not intended by a driver is prevented. When traveling control of a vehicle is performed through a remote operation from a remote control 3, a stop position of a vehicle 2 is set by a stop position setting device 9, and a movement course of the vehicle 2 is calculated by the vehicle course calculation device 10. In addition, the vehicle 2 is moved along the calculated movement course in response to a driving operation from the remote control 3, but if a driving operation from inside of the vehicle and a driving operation from the remote control 3 come into conflict, the driving operation from the remote control 3 is canceled, and the driving operation from inside of the vehicle is prioritized.Type: GrantFiled: January 31, 2011Date of Patent: February 17, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryuji Okamura, Yuka Sobue, Yu Hiei, Chika Morimoto

Publication number: 20150009330Abstract: An object detection device is equipped with an object detection unit that detects a moving object in a periphery of a vehicle, and a threshold change unit that changes, based on mobility information on the vehicle, a detection threshold in detecting the moving object. Thus, by changing the detection threshold T such that the moving object becomes difficult to detect during a movement of the host vehicle, especially during a turn thereof, the occurrence of an erroneous detection can be suppressed even in a situation where an erroneous detection is likely to occur. It is preferable that the detection threshold be changed such that the moving object becomes difficult to detect as a speed increases or as a steering angle increases. The detection threshold may be changed in stages or continuously based on the mobility information on the vehicle.Type: ApplicationFiled: February 6, 2012Publication date: January 8, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuka Sobue, Ryuji Okamura, Chika Yoshioka
