Embodiment Construction

[0025] The following description relates to systems and methods for operating a vehicle that has an ignition interface that is keyless or operated by a passive key, such as Figure 1-3 Displayed in the vehicle system. During a situation where the driver of the vehicle has left the vehicle at a standstill and keeps the engine running at idle, the automatic shutdown of the idle engine may be adjusted based on the parking position of the vehicle and further based on the environmental conditions at that position (for example, temperature). The engine controller can be configured to execute control programs, such as Figure 4 In order to automatically turn off the idle engine when parking in a closed space (such as an indoor parking lot). Conversely, when parking in an open space (such as an outdoor parking lot) and the outdoor conditions are poor, the automatic shutdown can be delayed to provide the desired cabin temperature when the vehicle driver returns to the vehicle. The contr...

Abstract

Methods and systems are provided for controlling the automatic shutdown of an idling vehicle engine. When the vehicle is parked in an enclosed space, the idling engine may be automatically shutdown, while when the vehicle is parked in an open space, the automatic shutdown may be delayed based on an ambient temperature. In this way, the vehicle cabin may be maintained at a temperature that provides enhanced driver comfort while allowing wasteful engine idling to be reduced.

Description

【Technical Field】 [0001] The present invention relates to a method and system for controlling the shutdown of a vehicle engine at an idle speed. 【Background technique】 [0002] In recent years, vehicles have been equipped with a new driver ignition interface to simplify vehicle operation. For example, the previous key-based interface has been replaced by a keyless or smart key interface. Although the previous key-based interface required the driver to start or stop the engine by inserting or removing a key (such as an active key) into the ignition system, the newer interface can be activated by pressing the start / stop button and / or based on a passive key (such as The smart key or electronic key fob) appears within the distance of the vehicle and allows the engine to be started or shut down. [0003] However, the inventor here has realized the potential problems of this type of system. In the absence of a physical device (such as an active key) that needs to be inserted / removed f...
