摘要:
Disclosed is an information processing system for a vehicle that calculates a recommended position of a driving operation in a predetermined area in which the driving operation is supported. The information processing system for a vehicle includes storage means for storing driving operation information of a driver and position information of the vehicle in each predetermined area so as to be associated with each other. The information processing system for a vehicle specifies a driving operation pattern of the predetermined area considering the state of the driving operation over the inside and outside of the predetermined area and determines the recommended position of the driving operation in the predetermined area according to the specified driving operation pattern, on the basis of the information stored in the storage means. According to this structure, even when some driving operations of a driving operation group included in the driving operation pattern are performed outside the area, it is possible to specify the driving operation pattern, determine the recommended position of the driving operation, and perform high-accuracy driving support suitable for the driver.

A navigation device includes a GPS receiver, map data including tunnel data and periodically acquires a vehicle's speed to provide guidance on the current position N acquired at the GPS receiver, and when GPS radio waves become unreceivable after the vehicle passes a tunnel entrance, calculates a travel distance according to a vehicle speed and a time T up to a branch, and continues providing guidance on the current position up to the branch. After passing the branch, the navigation device suspends guidance, calculates a distance La between the branch and a tunnel exit, which is shorter, and when GPS radio waves are not received even after a movement distance from the branch exceeds distance La, after passing the branch, determines a road whose distance is longer as the road being traveled, and provides guidance on the current position.

A method for locating an object by a reference grid, the object moving in a plane parallel to or identical to that of the grid. When crossing of a line of the grid is detected by the object, its heading is determined and, as a function of the detection, probabilities of the thus crossed line being a horizontal line and a vertical line respectively are obtained. Displacement of the object is assessed from the probabilities obtained and a horizontal and vertical pitch of the grid. A position of the object is then updated from a position of the object determined during a last line crossing of the grid and the displacement thus assessed.

The determining circuitry defines as, calculation positional information, positional information calculated based on a speed of a vehicle obtained by a speed obtaining circuitry and a period of time corresponding to an obtainment interval of positional information. The determining circuitry determines whether the positional information of the vehicle obtained from a positional information obtaining circuitry is abnormal based on a comparison between the calculation positional information and the positional information.

A method for filtering data in a tire pressure monitoring system for a vehicle includes the steps of: recording a variable that is dependent on the tire radius for a wheel of the vehicle, and filtering the variable that is dependent on the tire radius on the basis of driving dynamics data and/or a global navigation satellite system signal, called GNSS signal below. A vehicle control system and a vehicle having the control system are also described.

A road learning device includes: a map data storage device; an own vehicle location detection portion; a travel data storage device; an unregistered road travelling determination device; an unregistered road travel data storage control device; a potential unregistered road track creation device; a first correction device that corrects a potential unregistered road track to be a first track; a map-matching trial device for the first track; a primary successful map-matching determination device; a second correction device that corrects the first track to be a second track when primary map-matching is unsuccessful; a secondary successful map-matching determination device for the second track; and a new map data storage control device that discards a group of unregistered road travel data when secondary map-matching is unsuccessful, merges the first track with the map data when the primary map-matching is successful, and merges the second track with the map data when the secondary map-matching is successful.
摘要:
According to one embodiment, an electronic device includes a location detector, an acceleration detector, a processor and a navigator. The processor is configured to determine a mode of travel based on a detection value of the location detector and a detection value of the accelerometer, and record data associated with a location where the mode of travel changes. The navigator is configured to navigate a way to the location recorded in the data.

Various systems for detecting unauthorized exit events are disclosed. The systems can support a variety of different methods for assessing whether a customer is exiting the store without paying. The particular method or methods used may vary widely based on the types and the locations of the system components included in a given installation. For example, the system may be configured to detect that a cart has passed or is passing through a checkout lane.
