A vehicle control method according to an embodiment is a vehicle control method to be executed by a controller for controlling a vehicle that travels in an area, wherein the controller is configured to: in a case where detecting occurrence of a disaster and determining that nobody is riding on the vehicle, cause the vehicle to move to a refuge place, and the refuge place includes at least one of a place in which the vehicle having taken refuge hinders passage of an evacuee toward an outside of the evacuation route and a place in which the vehicle having taken refuge prevents an evacuee from entering a dangerous zone.

Vehicle control method and vehicle control device

A vehicle control method to be executed by a controller for controlling a vehicle that travels in an area including a plurality of floors, wherein the controller is configured to: in a case where detecting occurrence of a disaster and determining that a floor on which the vehicle exists is different from a floor on which a first evacuation place being a priority evacuation place exists, set a destination to a second evacuation place existing on a floor that is a same as the floor on which the vehicle exists; and cause the vehicle to move to the second evacuation place.

Vehicle control method, control device, and vehicle control system

When a crankshaft reversely rotates immediately before a stoppage of an engine, the amount of fuel injection in a cylinder in an expansion stroke is controlled to acquire a target air-fuel ratio in accordance with the amount of air in the cylinder. When the electronic control unit determines that the exhaust valve is opened at the time of reverse rotation, the amount of fuel injection is determined by considering a change in the amount of air due to exchange of gas with an exhaust path.

Start-up control device for engine

A starting control device for an engine includes an ECU configured to: i) execute an autonomous starting control in which the ECU injects fuel into the cylinder from a fuel injection valve after a crank shaft rotates reversely before the crank shaft stops its rotation and then ignites an air-fuel mixture using an ignition plug to start the engine without using a starter motor; ii) determine whether a pressure in the cylinder increasing due to the reverse rotation is equal to or greater than a predetermined pressure at a time point of firing of the air-fuel mixture by the ignition; and iii) prohibit starting of the engine under the autonomous starting control when the ECU determines that the pressure in the cylinder is not equal to or greater than the predetermined pressure.
