Title: Automatic stopping/starting device for engine
Inventor: KAMIYA MASARU
IPC: F02D29/02
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To carry out the control of the automatic stopping and starting of an engine suitably. SOLUTION: When a stop condition is realized, an engine is automatically stopped after elapsing a wait time Y (S70-S100). This wait time Y is set so as to get longer as the parameter X which is a car speed related physical amount after restart is smaller (S40). This parameter X is the average value, maximum value or integral value of a car speed V (S30). For example, when a car advances while repeating a very slow speed advance and stop after once stopping, for example when the car goes out from a narrow alley to a wide road, the average value of the car speed after restart becomes smaller and a wait time is set to longer. Therefore, such inconvenience that the engine is stopped contrary to a driver's aim can be prevented.  On the contrary, as the wait time is set short when an average car speed is big, when for example the wait time is set to 0, the engine can be stopped immediately after a condition is realized as usual.
