A travel control device executes an acquisition function to acquire object information including the position of an avoidance object which a subject vehicle should avoid, a planning function to plan a target route for the subject vehicle in accordance with the position of the avoidance object, and a control function to output command information for driving the subject vehicle on the target route. The planning function is used to specify a plurality of avoidance objects that are located within a predetermined distance from the subject vehicle and exist in the same lane adjacent to a lane in which the subject vehicle travels and to set a lateral position of the target route along the width direction of a road on which the subject vehicle is traveling. The lateral position of the target route is planned so as to avoid the avoidance objects.

Travel control device and travel control method

A travel control device acquires subject vehicle information including the position of a subject vehicle, acquires lane marker information including positions of lane markers, sets control areas with reference to the lane markers, and controls a travel position of the subject vehicle so that the subject vehicle travels between a pair of control areas set at right and left of the subject vehicle. The lane markers include a change-point lane marker and includes a course change point. When the pair of control areas set with reference to the change-point lane marker comprises one of the pair at a course change side of the subject vehicle and the other of the pair, the ratio of a width of the other to a width of the one is set larger than the ratio of the widths of control areas set with reference to a lane marker other than the change-point lane marker.

A moving body terminal is basically provided with a position information acquiring section, a receiving section and a control section. The position information acquiring section is configured to acquire position information indicating a current position of the moving body terminal. The receiving section is configured to receive from an information providing apparatus simple map information which includes information transmission determining information indicating an information transmission unnecessary region of the simple map information where the position information of the moving body terminal is not required to be transmitted from the moving body terminal to the information providing apparatus. The control section is configured to prohibit a transmission of the position information to the information providing apparatus when the position information acquired by the position information acquiring section is inside the information transmission unnecessary region contained in the simple map information that was received.

Moving body terminal, information providing apparatus, and information transmission method

An onboard vehicle information notifying apparatus has a moving body position acquiring section that acquires a moving body position for at least one moving body existing in a vicinity of a host vehicle and that acquires map information of the vicinity of the host vehicle. The map information is divided into a plurality of unit regions, with each of the unit regions being a notification necessary region when the moving body exists in the unit region. An information acquiring section acquires an advancement speed and an advancement direction of the host vehicle, and a prescribed movement speed of the moving body. An information providing zone setting section sets an information providing zone within which existence of the moving body should be reported. The information notifying section reports the existence of the moving body when the information providing zone overlaps with the notification necessary region.

Onboard vehicle information notifying apparatus

Moving body communication system, moving body terminal, information providing apparatus, and information transmission method

An information center apparatus has a communication section, a motion information calculating section, a communication delay time calculating section, a communication cycle waiting time calculating section, an error estimating section and a correcting section. The communication section acquires reported current position information of a first moving body apparatus and reports a corrected current position information to a second moving body apparatus. The error estimating section estimate an error in the reported current position information with respect to an actual current position of the first moving body apparatus based on motion information calculated by the motion information calculating section, communication delay times calculated by the communication delay time calculating section, and a communication cycle waiting time calculated by the communication cycle waiting time calculating section. The correcting section corrects the reported current position information using the error estimated by the error estimating section to obtain the corrected current position information.

Current position information reporting system, information center apparatus, and method thereof

An onboard vehicle information notifying apparatus is proved with a moving body position acquiring section, an information acquiring section, an information providing zone setting section and an information notifying section. The moving body position acquiring section acquires a moving body position for at least one moving body existing in a vicinity of a host vehicle. The information acquiring section acquires an advancement speed and an advancement direction of the host vehicle, and a prescribed movement speed of the moving body. The information providing zone setting section sets an information providing zone within which existence of the moving body should be reported, based on information acquired by the information acquiring section. The information notifying section reports the existence of the moving body when the position of the moving body acquired by the moving body position acquiring section exists within the information providing zone set by the information providing zone setting section.

Onboard vehicle information notifying apparatus, information providing system, and information notifying method

A cruise control device and method for controlling a vehicle such that the driver can set the speed setting at will, and the speed of the vehicle is controlled to match the speed setting. The speed limit for the road on which the vehicle is traveling is detected, and when the detected speed limit changes from a first speed limit to a second speed limit, the speed setting is selectively changed to the second speed limit. When the driver has performed an operation to change the speed setting before the detected speed limit changes from the first speed limit to the second speed limit, changing of the speed setting to the second speed limit is selectively suppressed.

Cruise control device and method for controlling the running of a vehicle

A vehicle passenger restricting system is provided to restrict passenger movement so that a space between a passenger's head and the ceiling of the vehicle is effectively enlarged when a rollover condition occurs. The vehicle passenger restricting system has a passenger seat, a rollover detector, a seat tilting device and a controller. The rollover detector detects a vehicle rollover condition. The vehicle passenger restricting device restricts passenger movement on the passenger seat. The seat tilting device tilts the seat in a backward direction. The controller activates the seat tilting device to recline the seat backwards when the rollover detector detects the vehicle rollover condition exists. Preferably, the controller also operates the restricting device when it determines that a rollover condition exists.
