An information providing apparatus includes a traffic information database and a data processing device. The data processing device detects, based on the traffic information data, an impediment event. The data processing device extracts the impediment event potentially encountered by an assisted vehicle. The data processing device calculates, based on the traffic information data, a certainty level of the impediment event. The data processing device provides a driver of the assisted vehicle with a straightforward notification regarding the impediment event potentially encountered by the assisted vehicle and having the certainty level equal to or higher than a straightforward notification threshold. The data processing device provides the driver with an euphemistic notification, which is different from the straightforward notification, regarding the impediment event potentially encountered by the assisted vehicle and having the certainty level less than the straightforward notification threshold.

Information providing apparatus for vehicle

An information providing apparatus for a vehicle includes: a traffic information database in which traffic information data are recorded; and a data processing device that processes the traffic information data to provide a driver of an assisted vehicle with a notification. The data processing device executes: an event detection process that detects, based on the traffic information data, an impediment event that impediments vehicle running; an event extraction process that extracts the impediment event potentially encountered by the assisted vehicle; a determination value calculation process that calculates a notification necessity level for each impediment event; and a notification process that provides the driver of the assisted vehicle with the notification regarding the impediment event potentially encountered by the assisted vehicle and having the notification necessity level greater than a threshold.

The data processing device detects, based on the traffic information data, an impediment event. The data processing device extracts the impediment event potentially encountered by an assisted vehicle. The data processing device provides a driver of the assisted vehicle with a notification regarding the impediment event potentially encountered by the assisted vehicle. The data processing device generates, based on the traffic information data, item data regarding a detailed item defined with respect to the impediment event. The data processing device generates, based on the item data, an analysis result regarding the detailed item and a confidence level of the analysis result. The data processing device changes, depending on the confidence level, contents regarding the analysis result to be included in the notification.

When a preceding vehicle in front of a host vehicle reduces speed, other vehicles between the preceding vehicle and a system-mounted vehicle successively reduces speed. An ECU and an ACC control the traveling of the system-mounted vehicle on the basis of prediction information of speed reduction propagation when the system-mounted vehicle reduces speed such that the system-mounted vehicle and an ordinary vehicle immediately in front of the system-mounted vehicle have a predetermined relative positional relationship. Therefore, it is possible to suppress the speed reduction propagation between the preceding vehicle and the system-mounted vehicle in advance, making it possible to more effectively suppress congestion.

A travel control plan generating systemincludes: upper level plan generating meansfor generating an upper level plan corresponding to a travel policy of a vehicle A; lower level plan generating meansfor generating a lower level plan, which is a plan for achieving the upper level plan and includes at least a travel course; lower level plan obtaining meansfor obtaining a lower level plan including at least a travel course of a peripheral vehicle B, C; evaluating meansfor evaluating the lower level plan of the vehicle A in accordance with a predetermined index, taking into account the lower level plan of the peripheral vehicle B, C; and lower level plan selecting meansfor selecting a lower level plan to be executed by the vehicle A on the basis of an evaluation performed by the evaluating means

Travel control plan generation system and computer program

A traffic control system sets a target value related to a travel state based on a correlation between a vehicle travel speed and a traffic volume, and controls multiple vehicles (CS) on a road in accordance with the target value as a common target value. The target value can be set based on a predicted traffic volume at a region () that is ahead of, in a vehicle travel direction, the multiple vehicles on the road. For example, the traffic control system sets, as the target value, a target speed or a target value of a parameter related to an inter-vehicle distance.

A vehicle control device calculates an operation amount and a motion state amount for varying an operation amount necessary for a real vehicle's operation based on a dynamic vehicle model modeling the motion state of a vehicle running in accordance with running targets such as a target path and a speed pattern and determines whether the calculated operation amount and the motion state amount satisfy prescribed running requirements. The operation amount and the motion state amount determined to satisfy the running requirements are a feed-forward (FF) operation amount and a target state amount in a state feedback (FB) control, respectively.

A vehicle state quantity prediction apparatus has sensors such as a GPS receiver that observe prescribed state quantities representing a movement state of a vehicle and a Kalman filter that inputs the state quantities observed by the sensors into a model of the movement state of the vehicle to predict a state quantity including the prescribed state quantities representing a movement of the vehicle. The reliability of the prescribed state quantities observed by the sensors is evaluated, and the degree to which the prescribed state quantities are reflected in the Kalman filter is set based on the evaluated reliability.

An apparatus for failure identification suitable for determining between existence and nonexistence of failure of the squib in occupant protecting system. The first terminal voltage generated between both the terminals of the squib when the first monitor current is passed through the squib, and the second terminal voltage generated between both the terminals of the squib when the second monitor current is passed through the squib. The first and second terminal voltages are amplified by the differential amplifier circuit into the first and second differentially amplified voltage. Thereafter, the difference between the first differentially amplified voltage and the second differentially amplified voltage is calculated to obtain the monitor voltage difference and it is compared with the reference voltage, and thereupon, decision between existence and nonexistence of a short-circuit in the squib is made.

An antitheft system comprises a prohibition device for prohibiting the alarming operation upon receipt of a disarmed memory signal. When an arming signal is inputted, an alarm is generated on the receipt of a theft detection signal generated by handling or operation of vehicle equipment or accessories. When a disarming signal is received, on the other hand, it is sotred and held as the disarmed memory signal in power-supply disconnected state.

A control device for a car wiper apparatus is disclosed, in which the wiper apparatus is driven in forward or reverse directions by the function of an electronic circuit. The control electronic circuit is so configured as to minimize the number of connection brushes for controlling the forward and reverse operations of the wiper motor which reciprocates the wiper blade. The reduced number of the connection brushes, which are arranged in the wiper motor, realizes a compact shape of the wiper motor as a whole. The electronic circuit functions to drive the wiper motor in forward and reverse directions within a predetermined angle thereby to rotate the crank arm connected with the wiper motor and the wiper blade with a small predetermined angle for reciprocal wiping operating, thus making it possible to mount the wiper apparatus in the small internal space of the car.
