Abstract: Navigation systems, methods, and programs acquire deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the route, and acquire post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point. The systems, methods, and programs determine based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point, and judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute is a first predetermined value or more. If the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, the systems, methods, and programs determine that guidance of the route is not appropriate.

Abstract: A housing for an electronic device unit includes a first case and a second case that are formed in a shape of a box with one of respective surfaces thereof being opened and are formed to be a box body. The housing includes an insulating plate that extends from the opening part of the first case to a side of the second case and overlaps with a wall surface of the second case. An engaging convex part is formed on a surface where the insulating plate is overlapped and an engaging hole that engages with the engaging convex part to regulate separation of the first case and the second case is formed. The insulating plate is in a shape in which an edge of the insulating plate spreads with a predetermined width from an opening edge where the first case and the second case are butted and the engaging hole.

Abstract: Devices, methods, and programs acquire provided information and position information that corresponds to the provided information from a provided information storage unit. The provided information has been provided to the provided information storage unit by an information provider and stored in the provided information unit with the position information. The position information specifies a position at which the provided information was provided by the information provider. The devices, methods, and programs acquire traffic-related information from a traffic-related information distribution unit. The traffic-related information includes information that specifies an occurring traffic-related event and information that specifies a range of the occurring traffic-related event.

Abstract: A driver model with higher precision is created as an evaluation standard for a driving condition in a normal condition. By detecting biometric information of a driver, whether a driver is in a usual condition or not is recognized. Then, data of driving conditions are collected while the driver is driving, and from the driving condition data, a part indicating that the driver operates in a usual condition is extracted to create a driver model. Further, the driver model is created taking only a case of driving in a normal condition as a driving action in normal times based on biometric information of the driver, and hence the driver model becomes more precise and neutral. Further, by using a GMM (Gaussian mixture model) for the driver model, a driver model for each driver can be created easily, and moreover, by calculation to maximize a conditional probability, a driving operation action is easily estimated and outputted.

Abstract: In the analog current output circuit according to the present invention, a rising start position and a tilt of an internal control voltage are set such that it crosses, at the maximum of an analog output current, a load end voltage obtained when the resistance of a load is the one near the center of a specification range. According to a comparison result in a comparator, a switch causes a DC/DC converter to input a high reference voltage and causes an output transistor to output a high power supply voltage when the internal control voltage is smaller than the load end voltage and causes the DC/DC converter to input a low reference voltage and causes the output transistor to output a low power supply voltage when the internal control voltage is larger than the load end voltage.

Abstract: An analog multiplexer with an insulated power supply includes: an analog signal transformer receiving an analog signal input in its primary winding via an FET, and ON/OFF driving the FET to generate a pulse with an amplitude of the analog signal in its secondary winding; a drive transformer receiving a drive pulse input in its primary winding via an FET to generate a pulse turning ON/OFF the FET in its secondary winding; an inhibit generation circuit generating an inhibit pulse having a wider pulse width than that of the drive pulse; an AND gate determining a logical product of a continuous pulse from a continuous pulse generation circuit and the inhibit pulse to obtain a power supply pulse train; and a rectifying/smoothing circuit obtaining a direct current voltage corresponding to the power supply pulse train to apply the direct current voltage to the primary winding of the transformer through high resistance.

Abstract: A driver model with higher precision is created as an evaluation standard for a driving condition in a normal condition. Further, a driving action is estimated using a driver model which can be created easily and can represent driving characteristics of a driver more precisely. By detecting biometric information of a driver, whether a driver is in a usual condition or not is recognized. Then, data of driving conditions (own vehicle information such as, for example, operation amounts of accelerator, brake, and steering wheel, vehicle speed, inter-vehicle distance, acceleration, and the like) are collected while the driver is driving, and from the driving condition data, a part indicating that the driver operates in a usual condition is extracted to create a driver model. Thus, without making the driver aware, a driver model for normal times can be created automatically.
