Abstract

Official abstract text for this publication.

A vehicle control device includes: a controller configured to adjust a temperature of an evaporator constituting an air conditioning system of the vehicle to a target temperature; the controller being configured to automatically stop an engine when a predetermined engine automatic stop condition is satisfied; the controller being configured to automatically start the engine when at least the temperature of the evaporator reaches a predetermined temperature or higher during automatic stop of the engine, and the predetermined temperature being higher than the target temperature; and the controller being configured to set the target temperature of the evaporator to be lower when a vehicle speed is low than that when the vehicle speed is high.

First claim

Opening claim text (preview).

The invention claimed is: 1. A control device for a vehicle, comprising: a controller configured to adjust a temperature of an evaporator constituting an air conditioning system of the vehicle to a target temperature; the controller being configured to automatically stop an engine when a predetermined engine automatic stop condition is satisfied; the controller being configured to automatically start the engine when at least the temperature of the evaporator reaches a predetermined temperature or higher during automatic stop of the engine, the predetermined temperature being higher than the target temperature; and the controller being configured to set the target temperature of the evaporator to be lower when a vehicle speed is low than that when the vehicle speed is high. 2. The control device according to claim 1 wherein the controller stores a period from automatic stop of the engine to automatic start of the engine in a past, and the controller sets the target temperature of the evaporator to be lower when the stored period is short than that when the stored period is long. 3. The control device according to claim 1 wherein the controller stores a frequency of the automatic stop of the engine, and the controller sets the target temperature of the evaporator to be lower when the stored frequency is low than that when the frequency is high. 4. A control method for a vehicle, comprising: adjusting, by a controller, a temperature of an evaporator constituting an air conditioning system of the vehicle to a target temperature; automatically stopping, by the controller, an engine when a predetermined engine automatic stop condition is satisfied; automatically starting, by the controller, the engine when at least the temperature of the evaporator reaches a predetermined temperature or higher during automatic stop of the engine, the predetermined temperature being higher than the target temperature; and setting, by the controller, the target temperature of the evaporator to be lower when a vehicle speed is low than that when the vehicle speed is high.
