Engine starting system for vehicle

摘要

Disclosed is an engine starting system for a vehicle, which comprises stop/restart control means operable, in response to satisfaction of a automatic engine stop condition when a automatic transmission mechanism is in a drive mode (D) (t0), to switch the automatic transmission mechanism from the drive mode (D) to a neutral mode (N) in an initial stage of an automatic engine stop control. In conjunction with the switching, the stop/restart control means is operable, in an event where an engine speed Ne is greater, by a given value or more, than a turbine speed Nt, to perform a buffering control (for example, D3 †’ D2 shift) configured to reduce transient vehicle vibrations to be caused by the switching, and, after the buffering control, to interrupt fuel supply for maintaining engine operation (t2). The engine starting system of the present invention can switch the automatic transmission mechanism from the drive mode to the neutral mode through the automatic engine stop control to achieve enhanced restart performance while reducing transient vehicle vibrations to be caused by the switching.
