Patent number: 9037332Abstract: The invention provides a vehicle having an obstacle detection device capable of improving the control accuracy of a motor and preventing the influence of noise on a sensor. A vehicle includes motors 31 and 32 which are AC motors, an inverter 2 that drives the motors, an ultrasonic sonar 1 which is, for example, a detector for detecting an obstacle around the vehicle, a frequency determining device 6 which determines whether noise generated from the inverter 2 is likely to interfere with a detection frequency of the detector, and a sonar ECU 5 which changes the carrier frequency of the inverter 2 when it is determined that the noise is likely to interfere with the detection frequency.Type: GrantFiled: March 17, 2011Date of Patent: May 19, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryuji Okamura, Yuka Sobue, Chika Yoshioka, Yu Hiei

Patent number: 8958986Abstract: A parking assistance apparatus includes a display unit that displays an image of a scene behind a host vehicle. At least when the host vehicle moves forward or when the host vehicle is stopped, the display unit displays an indication including a plurality of kinds of trajectories along which the host vehicle is able to back up from a point at which the host vehicle is currently positioned, in a manner such that the indication is superimposed on the image of the scene behind the host vehicle.Type: GrantFiled: June 28, 2011Date of Patent: February 17, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazunori Kagawa, Yuka Sobue, Satoru Niwa, Shin Tanaka, Akihisa Yokoyama, Kazuhiro Morimoto, Junichi Wakita, Chika Yoshioka, Yu Hiei, Ryuji Okamura

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

Patent number: 8868255Abstract: In a vehicle remote operating system remotely operating a host vehicle VM from a portable terminal 200, a main control unit 112 of an ECU 110 of an in-vehicle device 100 determines an dispatch position of the host vehicle VM on the basis of a parking position of the host vehicle VM and a position of a user U who intends to board the host vehicle VM. Due to this, it becomes possible to dispatch the host vehicle VM according to the parking position of the host vehicle VM and the position of the user U, and convenience is improved in dispatch operation and boarding of the host vehicle VM.Type: GrantFiled: April 12, 2010Date of Patent: October 21, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Chika Yoshioka, Kazunori Kagawa, Yuka Sobue, Satoru Niwa, Shin Tanaka, Kazuhiro Morimoto, Akihisa Yokoyama, Junichi Wakita

Patent number: 8768575Abstract: The recognizability of a vehicle peripheral environment may be enhanced. A vehicle periphery monitoring device is to monitor the periphery of a vehicle. The vehicle periphery monitoring device includes an imaging unit that obtains a plurality of peripheral images by imaging the periphery of the vehicle, a display unit that displays the plurality of peripheral images imaged in the imaging unit, and an image control unit that controls the plurality of peripheral images displayed in the display unit. The image control unit varies a distance between the plurality of peripheral images displayed in the display unit. As a result, sensory understanding of a vehicle peripheral environment by a driver may be enhanced, thereby enhancing the recognizability of the vehicle peripheral environment.Type: GrantFiled: March 18, 2011Date of Patent: July 1, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yu Hiei, Ryuji Okamura, Yuka Sobue, Chika Yoshioka
