Embodiment Construction

[0029] Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals are assigned to the same components. Since the names and functions of components assigned the same reference numerals are also the same, detailed descriptions thereof will not be repeated.

[0030] refer to figure 1 A vehicle equipped with a control device according to an embodiment of the present invention will be described. This vehicle is an FF (Front engine Front drive; front engine front wheel drive) vehicle. In addition, vehicles other than FF may be used.

[0031] The vehicle includes an engine 1000, an automatic transmission 2000, a planetary gear unit 3000 constituting a part of the automatic transmission 2000, a hydraulic circuit 4000 constituting a part of the automatic transmission 2000, a differential gear 5000, a propeller shaft 6000, wheels 7000, and an ECU (Electronic Control Unit; Electronic Control U...

Abstract

A control device and control method for a vehicle. When the execution condition of the fuel cut control is established (Yes in S100), the ECU executes a program including the following steps: the step of obtaining the temperature of the catalyst (S102); The step of selecting the throttle opening degree (S104), the step of executing the fuel cut control (S106), the step of executing the recovery control from the fuel cut control when the recovery condition for recovery from the fuel cut control is satisfied (YES in S108) ( S110).

Description

technical field [0001] The present invention relates to the control of a vehicle equipped with an internal combustion engine, and in particular, to the control of the opening degree of a throttle valve according to the catalyst temperature when fuel cut control is executed. Background technique [0002] Conventionally, there is known a technique of limiting the amount of intake air to prevent the catalyst from becoming a high-temperature state or a lean state when fuel-cut control is executed. [0003] For example, Japanese Unexamined Patent Publication No. 2001-152942 (Patent Document 1) discloses a control device for an internal combustion engine in which a decrease in driving feeling is suppressed as much as possible while using highly stable control based on fuel cut control as much as possible, and at the same time Prevents thermal aging and melting loss of exhaust gas purification catalysts caused by excessive temperature rise. The control device of the internal combu...
