20110105925 | DROWSINESS DETECTOR - A drowsiness detector capable of detecting light drowsiness of a subject with high precision is provided. The drowsiness detector acquires the measurement data of a measurement device first, and acquires a value of the pulse rate by performing preprocessing on the measurement data and extracts a pulse fluctuation from the value of the pulse rate. Then, the drowsiness detector sets the reference section width of the pulse feature value referred to in order to acquire the standard deviation of the pulse feature value (value of the pulse rate and pulse fluctuation) and then calculates the standard deviation value of the pulse feature value in the reference section width and acquires the corrected standard deviation value of the pulse feature value by dividing the standard deviation value of the pulse feature value by the pulse feature value. Then, the drowsiness detector determines whether or not the driver is lightly drowsy using the corrected standard deviation value of the pulse feature value. | 05-05-2011 |
20110313259 | PHYSIOLOGICAL CONDITION ESTIMATION DEVICE AND VEHICLE CONTROL DEVICE - Provided are a physiological condition estimation device and a vehicle control device capable of preventing an error in the operation of an apparatus, such as a vehicle, and improving the safety of the operation of the apparatus. The physiological condition estimation device includes an eye-open time acquiring unit that acquires the eye-open time of the driver, a variation calculating unit that acquires a variation in the eye-open time acquired by the eye-open time acquiring unit, and a drowsiness predicting unit that determines the physiological condition of the driver on the basis of the variation in the eye-open time acquired by the variation calculating unit. In this way, since the physiological condition is determined on the basis of the variation in the eye-open time, it is possible to detect a slight reduction in the arousal level and estimate a significant reduction in the arousal level to a value that will cause an error in the driving of the vehicle in the future. | 12-22-2011 |
20130241747 | VEHICLE INFORMATION TRANSMITTING DEVICE - A subject is to provide a vehicle information transmitting device capable of more clearly transmitting information to a driver. In the present embodiment, a virtual image for attracting attention in which a variation amount per unit change of color or luminance is set small is appeared under a situation where a relative deceleration of an object, i.e. a preceding vehicle, is small and thus attention attracting is necessary. A virtual image for warning in which the variation per unit change of color or luminance is set large is appeared under a situation where the relative deceleration of the object is large and thus warning is necessary. | 09-19-2013 |
20130249395 | VEHICLE INFORMATION TRANSMISSION DEVICE - A vehicle information transmission device includes: a display device that displays light in a first mode at a position of a vehicle body, at which visual recognition of a certain object is prompted, when the visual recognition is prompted and that displays light in a second mode different from the first mode on the vehicle body when the visual recognition is not prompted or when the visual recognition is prompted; and a control unit that adjusts light in the second mode on the basis of light in the first mode when the visual recognition is prompted. | 09-26-2013 |
20130249684 | VEHICLE INFORMATION TRANSMISSION DEVICE - A vehicle information transmission device prompts recognition of a certain object. The vehicle information transmission device prompts recognition of a position different from a position of the certain object. | 09-26-2013 |
20130258488 | VEHICLE INFORMATION TRANSMITTING DEVICE - In a vehicle information transmitting device, a plurality of light sources is arranged in an array form of plural rows or plural columns in the light source panel so that light can be irradiated in a horizontal direction (right and left direction) and vertical direction (height direction, up and down direction). The light source panel includes a diffusion plate and a shaft member for entirely or partially adjusting the transmitting degree (blurring degree of light) of the light of the light source in association with the arrangement position of the light source, and a plurality of springs that plays the role of a fail safe for maintaining the distance between the light source and the diffusion plate in a maximum state at the time of malfunctioning. | 10-03-2013 |
20130258693 | LIGHT SOURCE DEVICE FOR VEHICLE - The driver side of a light source panel is curved in a concave configuration which conforms with the curvature (curve) of the cross-section of the area of a front windshield glass, in which a virtual image is displayed. Individual light sources are arranged in the light source panel in a curved configuration which conforms with the curvature (curve) of the cross-section of the area of the front windshield glass, in which the virtual image is displayed. | 10-03-2013 |
20150183373 | VEHICLE INFORMATION DISPLAY DEVICE AND VEHICLEINFORMATION DISPLAY METHOD - A vehicle information display device including: a subject detecting sensor that detects an object in a surrounding area of a host vehicle; and a display portion that is configured to have a display area for displaying a display frame corresponded to the object in a mode of surrounding the object, and for emphatically displaying the object detected by the subject detecting sensor, and the display frame is displayed in a manner of that the emphasizing degree of an enlarging part is less than that of a non-enlarging part, when the display frame enlarges as the host vehicle moves. | 07-02-2015 |
20150187110 | VEHICLE INFORMATION DISPLAY DEVICE AND VEHICLE INFORMATION DISPLAY METHOD - A vehicle information display device including: a subject detecting sensor, that detects a first object positioned in a surrounding area of the vehicle and a second object different from the object; a display portion, that has a display area that displays an object mark corresponded to the object to emphatically display the object detected by the subject detecting sensor, and displays the second object mark so that when a number of the second objects that are in the vicinity of the detected first object and are detected by the subject detecting sensor is large, the emphasizing degree of the vertical component of the second object mark is suppressed in comparison with the emphasizing degree of the vertical component of the first object mark when the number of the second objects is small or no second object is detected. | 07-02-2015 |
