    摘要: A controller performs: trajectory generation processing of generating a target travel trajectory in such a way that, when a distance between a turning position of an own vehicle and a parked vehicle satisfies a predetermined condition, the own vehicle passes beside the parked vehicle at a predetermined side position with a predetermined interval interposed between the parked vehicle and the own vehicle on one side of the parked vehicle and a turning end position in a case of turning at a position before a position of the parked vehicle or a turning start position in a case of turning after having passed beside the parked vehicle on the route coincides with the predetermined side position in a width direction of a road on which the parked vehicle is parked; and processing of performing travel control, based on the target travel trajectory.

    摘要: A vehicle travel route control system controls a plurality of vehicles having an autonomous driving function or a driving assist function, wherein a vehicle dispatch information data server creates a travel route map, in which driving mode switching position at which vehicles have switched over during travel to the manual driving mode from the autonomous driving mode, have been added to a road map. Based on the travel route map, a travel route that avoids the driving mode switching position is calculated from among a plurality of routes on which a dispatch vehicle candidate travels to a destination via user position. When a travel route that avoids the driving mode switching position is calculated, a dispatch vehicle candidate is set as a dispatch vehicle, and the calculated travel route information is transmitted to an on-board unit mounted in the dispatch vehicle.

    摘要: Provided is a method of controlling a fuel cell system having a fuel cell stack, a reformer configured to reform a raw fuel and supply the reformed raw fuel to the fuel cell stack, a fuel flow rate control unit configured to control a flow rate of the raw fuel supplied to the reformer, an air supply pipe configured to supply oxygen to the raw fuel, and a combustor configured to mix a cathode discharged gas and an anode discharged gas discharged from the fuel cell stack and combust the mixed gas. The method of controlling the fuel cell system includes detecting at least one of a current value generated from the fuel cell stack and an oxygen supply amount supplied from the air supply pipe; estimating a composition of the anode discharged gas on the basis of at least one of the current value and the oxygen supply amount; and controlling a temperature of the combustor by adjusting the flow rate of the raw fuel using the fuel flow rate control unit on the basis of the estimated composition of the anode discharged gas.

    摘要: A method is performed for selecting a traffic lane of a roundabout for a motor vehicle traveling in the roundabout that has a plurality of traffic lanes and a plurality of exits. The method includes detecting the traffic lanes of the roundabout and third party driving on the traffic lanes, determining a first data relating to an occupancy level of the traffic lanes under consideration by third party vehicles, and a second data relative to the number of traffic lanes to be crossed in order to change traffic lanes from a current traffic lane to the lane in question, calculating the value of a cost function for each of the traffic lanes of the portion depending on the first data and the second data, and selecting one of the traffic lanes for the motor vehicle depending on each calculated value of the cost function.

    摘要: A vehicle allocation system is provided, which operates to move a vehicle to a predetermined point in response to a request from a user. The vehicle allocation system includes a boarding point determination apparatus, a control apparatus, and a user terminal apparatus. The boarding point determination apparatus includes a processor that operates to specify a second user who is expected to board in a predetermined range including a point associated with a first user, and calculate as the predetermined point a common point at which users including at least the first user and the second user board.

    摘要: The controller of the server of the information processing apparatus acquires the travel plan data relating to the travel plan of the vehicle from the communication terminal via the server communicator determines whether the map data needs to be updated, which is stored in the memory of the vehicle and used for travel in accordance with the travel plan. The controller transmits an inquiry signal inquiring of the user whether to permit updating of the map data to the communication terminal via the server communicator. The controller transmits an update instruction signal for instructing the update of the map via the server communicator to the on-vehicle communicator when receiving a permission signal permitting the update of the map data.
