摘要： PROBLEM TO BE SOLVED: To provide the information showing, based on the estimated arrival time of a vehicle useful for a user, such as store or the like (information showing the number of vehicles passing through a road adjacent to the store and the passing time of the road, or the like). SOLUTION: The computer 21 of a traffic information center 20 estimates the state (congestion, weather) of roads constituting the route from the starting point P of each vehicle to a designation G, estimates the traveling speed when the driver of the same vehicle operates the vehicle under the estimated road state as favorite driving speed, and estimates the arrival time to each road on the route from the starting point to the designation by use of the distance of the road and the estimated favorite driving speed. These estimations are performed for each vehicle, the number of vehicles present at a prescribed time in the road adjacent to the use, such as store requesting the information is estimated, and the estimated number of vehicles is provided to the user, such as the store with the time.

摘要： PROBLEM TO BE SOLVED: To provide an information presentation system which provides the information relating to destinations reflecting the experiences and tastes of all of the people acting together. SOLUTION: The information on the destinations, routes, etc., respectively visited by respective users is sent at suitable timing from navigation units 20 and portable terminals 24, by which the information is accumulated as histories by each of the users into a data memory section 54 for the histories, such as visiting places, of a service center 22. When vehicle crew members make a request for route provision to the service center 22, identification ID codes of all of the vehicle crew members are sent to the navigation units 20 and the service center 22 is instructed to retrieve the roads optimum for the vehicle crew members as the routes up to the destinations in accordance with the data on the histories of the visiting places of all of the vehicle crew members. The results of the retrieval are sent from the service center 22 to the navigation units 20 and the vehicle crew members are provided with the results of the retrieval from a video output sections 44 of the navigation units 20.

摘要： PURPOSE:To make generated torque to respective cylinders uniform and prevent generation of engine vibration or surging phenomenon by correcting valve opening time set through a valve opening time setting means at every control valve according to difference between rotating speed of each cylinder and mean value of rotating speed of all cylinders. CONSTITUTION:A valve opening time setting means l sets the valve opening time of a control valve 5 according to an engine operating condition. The set valve opening time is in same value to each control valve. A rotating speed detecting means 2 detects rotating speed of each cylinder from the top dead center of compression stroke to the bottom dead center of expansion stroke, and outputs to a mean rotating speed computing means 3 and a correcting means 4. The mean rotating speed computing means 3 computes the mean rotating speed of all cylinders, and outputs to the correcting means 4. The correcting means 4 corrects the valve opening time set by the valve opening time setting means l at every control valve 5 according to deviation between the input mean rotating speed and the rotating speed of each cylinder, and supply air quantity is adjusted at every cylinder.
