  • Publication number: 20220219683
    Abstract: Provided is a vehicle control system for avoiding a collection between a right-turning vehicle and a straight-through vehicle without decreasing comfort for an occupant. In the system, a first vehicle V1 and a second vehicle V2 retain high-precision map data for identifying a traveling lane. When the first vehicle V1 traveling in an autonomous driving mode intends to turn right from a right turn lane at an intersection ahead based on the high-precision map data, the first vehicle V1 transmits a right turn notification indicating the intention to turn right to nearby vehicles using vehicle-to-vehicle communications. When the second vehicle V2 traveling in an autonomous driving mode intends to travel straight at an intersection ahead, the second vehicle V2 recognizes a right-turning vehicle in an oncoming lane at the intersection upon receiving the right turn notification from the right-turning vehicle, and performs a predetermined control for collision avoidance.

  • Publication number: 20220223036
    Abstract: A vehicle system includes: a controller configured to communicate with a map server; and a vehicle position acquiring device configured to acquire own vehicle position information. The controller includes: a vehicle position determining unit configured to determine a lane in which an own vehicle is traveling based on the own vehicle position information; a storage unit configured to store an attendant circumstance of the own vehicle; and a recommended lane determining unit configured to determine a recommended lane. The recommended lane determining unit is configured to set a priority of each lane based on map information, determine the lane having a highest priority as the recommended lane, and exclude a travel prohibited lane, in which travel of the own vehicle is prohibited, from a candidate for the recommended lane based on restriction information and the attendant circumstance.

  • Publication number: 20220219723
    Abstract: A vehicle system includes: a map processing unit that creates local map data based on high accuracy map data and a position of an own vehicle; and an autonomous driving control unit that creates a travel plan for autonomous traveling of the own vehicle based on the local map data and controls traveling of the own vehicle according to the travel plan. The map processing unit creates multiple pieces of transmission data by dividing the local map data so as to correspond to regions on a map and transmits the multiple pieces of transmission data to the autonomous driving control unit. The map processing unit changes a shape and a size of the region on the map corresponding to each piece of transmission data based on selection information which decides a travel mode.

  • Patent number: 8491887
    Abstract: An anticancer therapy using autologous cells or the like, which induces the regression of cancer or has favorable drug delivery effects and brings about reduction or withdrawal of a hypoxic region(s) in tumor is provided. Transplantation of endothelial progenitor cells, via intravenously or other methods leads to tumor growth inhibition, an increase of the vascular density with an enlargement of the vascular diameter, and reduction of a hypoxic region(s) in the tumor. Allogeneic transplantation of endothelial progenitor cells may be achieved to secure the cells for the therapy, however, autologous transplantation of endothelial progenitor cells from cancer patients would be desirable to evade rejection. When autologous cells are used, mononuclear cells are separated from the peripheral blood or bone marrow of the patient and cultured using an endothelial differentiation medium containing cytokines such as VEGF to obtain adherent cells, which can then be collected and used as endothelial progenitor cells.

  • Patent number: 6253150
    Abstract: A navigation ECU 1 retrieves stop-position data from a map data base 8, calculates a distance between a present position of a self vehicle and a stop position closest to the present position of the self vehicle, and judges whether or not the distance is within 300 m. If it is within 300 m, the ECU 1 generates a stop informing message or a slow-down warning. Further, when a distance between a present position of the self vehicle and the stop position closest to the present position is reduced to within 5 m, the ECU 1 instructs the driver of the self vehicle to cautiously look right and left.

  • Patent number: 5710556
    Abstract: A device for locating a moving body includes:an interrogation unit (10) for communicating with a response unit (50) mounted on a vehicle (51) present in a lane of a communication zone "a"; receiving antennas (21, 22) having receiving areas "21b, 22b" divided in the width direction of the lane; and a processor (40) for determining the position of the vehicle in the communication zone based on a reception result from the receiving antennas. The device may also include a detecting device such as an imaging device (30) having an imaging area "c" of a size equal to the lane. This makes it possible to recognize an unauthorized vehicle (52) not having a response unit and thus passing through the imaging area "c" without a radio signal to be received by the receiving antennas (21, 22).
