摘要： PROBLEM TO BE SOLVED: To prevent degradation of calculation accuracy of a target trajectory due to change of atmospheric pressure, in a system for learning target trajectory information (reference revolution speed used for calculation of a target trajectory and a deviation of loss torque) based on actual engine revolution behavior when engine revolution stop control is performed.SOLUTION: Atmospheric pressure is detected by an atmospheric pressure sensor 38 when an engine stop request occurs, an atmospheric pressure correction amount corresponding to a difference between atmospheric pressure at the time of previous engine stop request and atmospheric pressure at the time of an engine stop request of this time is calculated, and a learning value of the target trajectory information (reference revolution speed and the deviation of loss torque) is corrected using the atmospheric pressure correction amount, so that the learning value of the target trajectory information is properly corrected correspondingly to change of actual target trajectory information (a true value of the target trajectory information) depending on the atmospheric pressure and the learning value of the target trajectory information is made close to the true value. Calculation of the target trajectory using the learning value of the target trajectory information after the correction prevents degradation of calculation accuracy of the target trajectory due to change of the atmospheric pressure.

摘要： PROBLEM TO BE SOLVED: To allow controllability of load torque of an alternator to be secured by preventing suppression of power generation current of the alternator during engine revolution stop control.SOLUTION: Prior to the start of engine revolution stop control (alternator F/B stop control) for feed-back control of load torque of an alternator 33 so as to match an actual engine revolution behavior to a target trajectory, consumption power increase control for increasing the power consumption of a vehicle is performed for a predetermined time. By the power consumption increase control, power of a battery 32 is consumed to increase electric energy chargeable to the battery 32 by just that much, thereby increasing electric energy (= consumed electric energy of the vehicle + chargeable electric energy of the battery 32) acceptable for the vehicle. Thereby, during the engine revolution stop control, power generation electric energy of the alternator 33 is prevented from exceeding the electric energy acceptable for the vehicle, thus preventing the power generation current of the alternator 33 from being suppressed by a regulator.

摘要： PROBLEM TO BE SOLVED: To appropriately determine the necessity of operation of an engine start device and suppress troubles of the start device being unnecessarily driven.
SOLUTION: An ECU 40 automatically stops an engine 10 when a prescribed automatic stop condition is established, and when a prescribed start condition is established during the automatic stop of the engine 10, automatically restarts the engine 10.

摘要： PROBLEM TO BE SOLVED: To expand a self-recoverable (starter-less startable) rotational speed region to a lower rotation side when restart request occurs during engine rotation drop by idling stop control.
SOLUTION: When determining whether or not self-recovery is allowed at the occurrence of a restart request during engine rotation drop by idling stop control, predicted engine rotation speed in ignition timing producing initial combustion is calculated on the basis of engine rotation speed in occurring timing of restart request (1), engine rotation drop speed (2) and a crank angle from the occurring timing of start request to an ignition timing producing initial combustion (3) in consideration of engine rotation speed drop during a period from occurring timing of restart request to ignition timing generating initial combustion (initial explosion). Whether or not self-recovery is allowed is determined by whether or not the predicted engine rotation speed is not less than determination threshold equivalent to the lower limit value of a self-recoverable rotation speed region.
