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: 7499001Abstract: The dielectric antenna device of the present invention is a dielectric antenna device having at least one feed element that is buried in a dielectric. The interval between the end portion of the feed element and the end face of the dielectric in a direction passing through the end portion of the feed element from a feeding point thereof is substantially 1/20 or more of the wavelength of a wireless signal that is formed within the dielectric. This constitution provides a dielectric antenna device that has stabilized resonance frequency.Type: GrantFiled: October 7, 2005Date of Patent: March 3, 2009Assignee: Pioneer CorporationInventor: Tomoyuki Fujieda
