Publication number: 20220404166Abstract: There is provided a technique for improving the accuracy of estimation of a position of a nearby vehicle. A nearby vehicle position estimation system is formed that includes a relative position information obtaining part that obtains relative direction of a nearby vehicle with respect to a host vehicle, the nearby vehicle being present around the host vehicle; a map information obtaining part that obtains map information around a current position of the host vehicle; and a nearby vehicle position estimating part that obtains, based on the map information, a nearby road that overlaps a straight line extending in the relative direction from the host vehicle, and estimates that the nearby vehicle is present on the nearby road.Type: ApplicationFiled: October 2, 2020Publication date: December 22, 2022Applicant: AISIN CORPORATIONInventors: Isao MORIBE, Toshifumi MICHIDA, Tomoaki HIROTA, Ryosuke TOBUCHI

Patent number: 10878256Abstract: Travel assistance devices and programs obtain a captured image that captures a surrounding environment of a vehicle by an imaging device having a start point of a driver's line of sight and an optical axis corresponding to a driver's line-of-sight direction. The devices and programs identify, based on the captured image and map information of an area around the vehicle, a location where a connecting road is present in the captured image. The connecting road is a road connecting to a traveling road of the vehicle at a divergence point present around the vehicle. The devices and programs determine driver's visibility of the connecting road based on a positional relationship between the location of the connecting road and a location of an obstacle present around the vehicle in the captured image and output a result of the determination.Type: GrantFiled: October 9, 2017Date of Patent: December 29, 2020Assignee: AISIN AW CO., LTD.Inventors: Takamitsu Sakai, Nozomi Jimbo, Tomoaki Hirota

Publication number: 20190251374Abstract: Travel assistance devices and programs obtain a captured image that captures a surrounding environment of a mobile unit and obtain, as a map information image, a map image that three-dimensionally represents a map and that represents a same range as an image capturing range of the captured image from a same direction as an image capturing direction of the captured image. The devices and programs extract a risk factor based on learning data by inputting the captured image and the map information image to machine learning as input images with a plurality of channels. The risk factor is present in the surrounding environment of the mobile unit and is not included in the captured image.Type: ApplicationFiled: October 9, 2017Publication date: August 15, 2019Applicant: AISIN AW CO., LTD.Inventors: Takamitsu SAKAI, Tomoaki HIROTA

Patent number: 10263654Abstract: A radio frequency signal can be received in an intermediate frequency mode suitable for radio wave reception conditions. An oscillator has a variable oscillation frequency. A quadrature demodulator includes a frequency mixer and generates an intermediate frequency signal having an intermediate frequency lower than the frequency of the radio frequency signal. An ADC receives the intermediate frequency signal passed through an analog filter and converts the received intermediate frequency signal to a digital signal. A channel selection signal processing section generates a demodulated signal from the intermediate frequency signal converted to the digital signal. A mode control section switches the operating mode of the quadrature demodulator between a zero intermediate frequency mode and a low intermediate frequency mode in accordance with the radio wave reception conditions.Type: GrantFiled: February 6, 2018Date of Patent: April 16, 2019Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Naohiro Matsui, Hiroyuki Okada, Kichung Kim, Tomoaki Hirota, Takahiro Sato, Osamu Inagawa
