A driving consciousness estimation device includes a driving readiness degree estimation unit configured to estimate a driving readiness degree relating to a driving consciousness of a driver based on a reaction time or a width of field of view of the driver and at least one of a time duration of eye glance away from road environment and an arousal level of the driver. An influence of the reaction time or the width of the field of view on the driving readiness degree estimated by the driving readiness degree estimation unit is greater than an influence of at least one of the time duration of eye glance away from road environment and the arousal level on the driving readiness degree.

A driving consciousness estimation device is configured to estimate a driver's driving consciousness of a host vehicle as a driving readiness degree. The device includes a viewing target recognition unit configured to recognize a viewing target used for estimating the driving readiness degree based on a result of detection by an external sensor of the host vehicle, a driver's line of sight recognition unit configured to recognize a driver's line of sight, a viewing reaction index calculation unit configured to calculate a driver's viewing reaction index for the viewing target based on the driver's line of sight recognized by the driver's line of sight recognition unit, and a driving readiness degree estimation unit configured to estimate the driving readiness degree based on the viewing reaction index.

A driving consciousness estimation device includes a driving readiness estimation unit configured to estimate a driving readiness relating to a driving consciousness of the driver from a driver's reaction to the travelling environment, a driving task demand estimation unit configured to estimate a driving task demand which is an index required for the driver with respect to the driving readiness from the travelling environment, and an attention awakening unit configured to execute awakening of attention for the driver relating to the driving of the vehicle based on the result of comparison between the driving readiness and the driving task demand.

An information display device includes an attention object recognition unit that recognizes a plurality of attention objects, a traveling state recognition unit that recognizes a vehicle speed of a vehicle, a HUD that displays attention display, an attention depth calculation unit that calculates TTC and calculates attention depths for the attention objects on the basis of the TTC, a display information generation unit that determines a first attention object having the largest attention depth among the plurality of attention objects and generates first display information regarding first attention display for highlighting the first attention object and second display information regarding second attention display which is a line surrounding the first attention object and second attention objects other than the first attention object among the plurality of attention objects, and a display control unit that displays the first attention display and the second attention display on the HUD.

Information display device

A vehicle driving situation determination apparatus includes an object detector for detecting an object around a vehicle and an electronic control unit (ECU). The ECU calculates an index relating to a traveling state of the vehicle, wherein the index is a value that is obtained by dividing a jerk of the vehicle by a deceleration. The ECU compares the index to past index statistics, in a case where the object is detected by the object detector and then a response operation against the object by a driver of the vehicle is detected. A driving reaction of the driver of the vehicle is based on a result of this comparison and driving support is executed based on the determination.

According to an embodiment, there is provided a drive assist device including an index calculation unit configured to calculate an index relating to a relative relationship between a vehicle and a target object and a drive assist determination unit configured to determine whether to execute a drive assist control of the vehicle based on the index and as the vehicle width direction component of the relative speed between the vehicle and the target object decreases, the index calculation unit calculates the index with increasing a degree of influence of the relative relationship relating to the vehicle width direction component, or as the vehicle width direction component of the relative distance between the vehicle and the target object increases, the index calculation unit calculates the index with increasing the degree of influence of the relative relationship relating to the vehicle width direction component.

Drive assist device, and drive assist method

A control apparatus for input screens includes a display unit, a switch portion and a control unit including a microcomputer. If one of a menu switch of the switch portion and a plurality of dummy switches included in a screen displayed by the display unit is operated, the microcomputer causes the display unit to display a new screen including a plurality of dummy switches. The microcomputer estimates a time period required for the operator to watch a screen to operate the dummy switch, depending on the displayed screen (the number of dummy switches). If the sum of estimated time periods exceeds a reference time period, the microcomputer nullifies operation of the dummy switch to prevent the screen from being switched. After the lapse of a predetermined time period, the microcomputer cancels the nullification of the operation of the dummy switch.

Control apparatus and method for input screens

A voice route-guidance system for vehicles which terminates its route-guidance when the vehicle arrives at the destination and even if the present position of the vehicle is measured with low accuracy. An approach judging unit judges that the vehicle approaches a point spaced apart from a destination by a predetermined distance. A guidance termination judging unit further judges whether or not there is a point in which the route-guidance should be carried out between the present vehicle position and the destination. From these judgments, the system judges that the vehicle approaches the point spaced apart from the destination by the predetermined distance and also that all the route-guidance has been terminated. Thus, a termination unit terminates the route-guidance.

Voice route-guidance system and method having a function for judging

A voice expression selection processing section recognizes a route from data from a route memory. When a vehicle has reached a junction, it is judged whether or not a curved road is present at the junction on the basis of connecting road number data from a junction data storage section, connecting angle data and connecting road width data. The content of the voice expression is changed in accordance with a case where the curved road is present or another case where the curved road is absent. Particularly, when the curved road is present, the direction of this curved road is added as a base of the voice expression. Therefore, the voice expression which matches with the feeling of a driver can be carried out to achieve suitable car guidance.

Vehicle-guiding device for recognizing curved road and leading vehicle

A vehicle navigation system realizing a discrete display of the present position of a vehicle during a period from when the vehicle reaches a predetermined distance before an intersection until the vehicle passes the intersection. Especially, in a zone a short distance before the intersection, the present vehicle position mark is fixed at the center of the displayed intersection until the travelling direction of the vehicle is changed. Thereby, even when the accuracy of monitoring of the present position is relatively low, misindication, such that the present position is displayed as if the vehicle has passed straight through the intersection in spite of not having actually reached the intersection, is avoided.

Vehicle navigation system and navigation method

An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.
