Patent number: 10713511Abstract: A recognition timing estimation device configured to estimate a timing of a driver's recognizing action related to a subsequent travel segment of a plurality of travel segments that constitute a traveling course of a vehicle, is provided. The device includes a processor configured to execute a traveling information acquiring module to acquire information related to a driving operation of a driver or the traveling course, a travel segment estimating module to estimate a pause between the travel segments based on the information acquired by the traveling information acquiring module, an eye detecting module to detect a behavior of a driver's eye, and a recognition timing estimating module to estimate the timing of the driver's recognizing action based on a temporal relationship between the pause between the travel segments estimated by the travel segment estimating module and the behavior of the eye detected by the eye detecting module.Type: GrantFiled: November 15, 2018Date of Patent: July 14, 2020Assignee: Mazda Motor CorporationInventors: Yuka Minegishi, Keiichi Tomii, Yasutaka Kajiwara, Takahiro Tochioka

Patent number: 10613531Abstract: A vehicle drive assistance system is provided, which includes a control unit configured to perform a drive assistance control based on a balance state between a driver's required driving ability required for driving a vehicle based on a traffic environment around the vehicle and drive assistance which is provided to the driver by the vehicle, and a driver's current driving ability. The control unit includes a processor configured to execute a balance determining module to determine the balance state between the required driving ability and the current driving ability based on a physical quantity related to a driving operation by the driver.Type: GrantFiled: February 22, 2018Date of Patent: April 7, 2020Assignee: Mazda Motor CorporationInventors: Yuka Minegishi, Keiichi Tomii, Takahiro Tochioka
