Embodiment Construction

[0029] Embodiments will be described below with reference to the drawings. In the following description, the same reference numerals are used for the same or corresponding elements, and overlapping descriptions are omitted.

[0030] Such as figure 1 As shown, the driving intention estimation device 100 includes an ECU (Electronic Control Unit) 10 that manages the device as a whole. The ECU 10 is an electronic control unit including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In the ECU 10 , for example, programs stored in the ROM are loaded into the RAM, and the programs loaded into the RAM are executed by the CPU to realize various functions. The ECU 10 may also be composed of a plurality of electronic control units.

[0031] The ECU 10 is connected to a driver monitoring camera 1 , an external sensor 2 , an internal sensor 3 , a GPS (Global Positioning System) receiving unit 4 , a map database 5 , and an HMI 6 . ...

Abstract

A driving consciousness estimation device includes a driver state estimation unit configured to estimate a state of a driver of a host vehicle, a manual driving ability estimation unit configured to estimate a manual driving ability of the driver based on at least one of a travel state of the host vehicle, a traveling environment around the host vehicle, and a reaction of the driver, and a driving readiness calculation unit configured to calculate a driving readiness relating to a driving consciousness of the driver based on the state of the driver and the manual driving ability of the driver.

Description

technical field [0001] The present disclosure relates to a driving intention estimation device. Background technique [0002] As a technique related to the driving intention estimation device, a device described in Japanese Patent Application Laid-Open No. 2017-199279 is known. In the driving intention estimating device described in Japanese Patent Laid-Open No. 2017-199279, the driving readiness related to the driving intention of the driver is calculated based on an image of the driver (driver) of the vehicle. [0003] However, regarding the driving readiness, for example, there are individual differences due to the driver's manual driving ability. In addition, regarding the driving readiness, even for the same driver, there are intraday fluctuations depending on, for example, the state related to the manual driving ability (clearness of the mind, fatigue of the hands, etc.). However, in the driving intention estimation device described above, such characteristics of the...
