Patent number: 10520324Abstract: An enhanced map information processing unit 14 of a driving assistance device 1 acquires from a determination unit 13 information on surroundings of a vehicle which is needed to perform autonomous driving, and acquires from a server device 2 environment information on surroundings of a route on which autonomous driving is performed. On the basis of the acquired environment information, the enhanced map information processing unit 14 extracts, as an autonomous driving unsuitable location Pn, a location at which the accuracy of the acquirement of the sensor unit 12 is predicted not to satisfy a standard for acquiring the information on the surroundings of the vehicle needed to perform autonomous driving. An informing unit 18 alerts the extracted autonomous driving unsuitable location Pn to a user.Type: GrantFiled: September 1, 2017Date of Patent: December 31, 2019Assignees: PIONEER CORPORATION, INCREMENT P CORPORATIONInventors: Tomoaki Iwai, Yuji Tawaragi, Tomoyuki Fujieda, Tetsuya Kawahara, Youko Fujita

Patent number: 7568079Abstract: A storing-reproducing unit 200 recognizes a free space of a contents storage area by a storage-area-administrating device, sets a recording timing duration based on the recognized free space of the contents storage area, and selects a schedule information of a contents to be recorded from recording schedule list information. Hence, frequency of storing the contents in the HDD 270 can be reduced, thereby avoiding that the contents which has not yet watched is erased by self-erasing, so that the contents can be effectively recorded. Therefore, a user can secure flexibility in time in watching the contents.Type: GrantFiled: June 2, 2005Date of Patent: July 28, 2009Assignee: Pioneer CorporationInventors: Naoaki Horiuchi, Motooki Sugihara, Tetsuya Kawahara, Harumi Nakamura, Hideki Nagata
