A control device for a vehicle includes an electronic control unit. The electronic control unit is configured to: execute first automatic stop control for automatically stopping an engine when a first condition is established during traveling of the vehicle; execute second stop control for automatically stopping the engine when a second condition is established during stop of the vehicle; predict a vehicle stop duration; calculate a required cold and heat storage amount of an evaporator; calculate a reaching time until a cold and heat storage amount of the evaporator reaches the required cold and heat storage amount; predict a time needed for vehicle stop; and when the first condition is established during traveling of the vehicle, in a case where the calculated reaching time is equal to or longer than the predicted time needed for vehicle stop, automatically stop the internal combustion engine during traveling of the vehicle.

A remote startup system includes a terminal of a user, a center server that is configured to communicate with the terminal, and a vehicle that is configured to communicate with the center server, and starts up an engine of the vehicle according to a startup request transmitted from the terminal to the center server. The remote startup system includes a position information acquisition unit that acquires position information of the vehicle, a time information acquisition unit that acquires time information, and a controller that changes a performance manner of the startup of the engine based on the startup request including whether the startup of the engine is permitted according to the position information of the vehicle and the time information when the startup request is transmitted from the terminal to the center server.

A vehicle traveling control method includes starting, when a predetermined condition is satisfied, inertial traveling during which a vehicle travels while stopping fuel supply to an engine of the vehicle, measuring, from a start of the inertial traveling, a temperature decrease amount occurring in a heat exchanger for heating a cabin of the vehicle with heat generated by the engine, and stopping the inertial traveling when the temperature decrease amount is greater than a threshold.

A vehicle includes an engine, automatic transmission, and a controller. The engine is configured to auto-start and auto-stop. The automatic transmission has a shift-by-wire gear selector. The controller is programmed to, in response to shifting the gear selector to a neutral position while the engine is running, command the engine to auto-stop.

A method to control engine start-stop in a vehicle is provided. The method includes outputting via a controller an engine command to auto-start the engine based on detection of a predetermined vehicle condition affecting fuel economy of the vehicle, detection of a shift from neutral to another gear position, and whether a predetermined time threshold has expired following the shift in response to detection of a presence of an engine auto-stop mode and a neutral gear position. The predetermined vehicle condition may be a movement of the vehicle in a reverse direction. The predetermined vehicle condition may be a battery parameter being outside of predetermined range. The predetermined range may be based on a battery state of charge, a battery temperature, a battery voltage, or a battery load current. The predetermined vehicle condition may be a HVAC component activation.

A start-stop device for commencing an automatic switch-off process of a drive machine in a motor vehicle includes means for detecting a first trigger condition for initiating an automatic switch-off process, means for detecting a second trigger condition for initiating an automatic switch-off process if the first trigger condition can no longer be met, and means for initiating an automatic switch-off process of the drive machine if the first trigger condition or the second trigger condition is met.

A method for guaranteeing starting performance of an engine for maintaining driving performance is provided. The method includes executing a quasi-failure mode in which the engine is changed to a driving state when an engine cranking apparatus state is maintained equal to or less than a threshold for a predetermined period of time. As a result, the engine is driven in the quasi-failure mode while the hybrid vehicle is driven in the EV mode to prevent the vehicle system from being aggravated and fundamentally preventing the degradation in the stability of the vehicle causing driver discomfort.
