Abstract: A control apparatus controls an automatic stop of an engine mounted on a vehicle so as to automatically stop the engine if a predetermined stop condition is satisfied, the stop condition including a condition that a running speed of the vehicle is a prescribed speed or less. The control apparatus includes a prediction unit and a prohibition unit. The prediction unit predicts whether or not the next automatic stop time of the engine is less than a prescribed time capable of obtaining a fuel saving benefit based on a history of a vehicle stop time or an automatic stop time of the engine. The prohibition unit prohibits the next automatic stop of the engine if the prediction unit predicts that the next automatic stop time of the engine is less than the prescribed time.

Abstract: A control apparatus for an idle-stop system mounted on a manual-transmission-vehicle includes a restart unit performing a restart operation of the engine such that the restart unit drives a starter to restart the engine when a predetermined restart condition is met. The restart condition includes a condition where a clutch member is operated to allow the motive force to be transmitted between the output shaft of the engine and the driving wheel of the vehicle while the motive force has been blocked by the clutch, and a condition where the brake member is operated to stop applying the braking force to the wheel while the motive force has been blocked by the clutch.

Abstract: In a system, an angle sensor outputs a pulse each time an output shaft of an internal combustion engine rotates by a preset angle, and a calculator calculates speed-change information indicative of a change in a speed of rotation of the output shaft based on the pulses outputted from the angle sensor. A determiner determines, based on the speed-change information, whether at least one of the pulses outputted from the angle sensor represents a proper timing for a preset of a pinion of a starter with a ring gear mounted on the output shaft. A pinion engaging unit shifts the pinion toward the ring gear so that the pinion is engaged with the ring gear when it is determined that the at least one of the pulses outputted from the angle sensor represents the proper timing for the preset of the pinion with the ring gear.

Abstract: A vehicle has a drive control ECU that controls an internal combustion engine or a transmission on the basis of a target drive force. The drive control ECU has a first arbitrator that sets the target drive force on the basis of a driver's request and the like, and filters that have individually different damping characteristics and that correct the target drive force from the first arbitrator so that the vibration of a sprung weight of the vehicle is controlled, as well as a switch that includes a switching portion and a filter setting portion. The filter setting portion determines whether a pitching resonance frequency has changed. If having determined that the pitching resonance frequency has changed, the filter setting portion switches the filter having been used for correcting the target drive force to a filter corresponding to a post-change pitching resonance frequency.

Abstract: A controller controls braking force and driving force of a vehicle, in accordance with demand force. The controller includes a first and second demand force arithmetic units for arithmetically calculating first and second demand force. The first demand force includes a factor inducing vibration in suspended components of the vehicle. The second demand force substantially excludes the factor inducing vibration in suspended components of the vehicle. A vibration damping filter reduces the factor from a waveform of the first demand force, thereby producing post-filter demand force. An arbitration unit compares the post-filter demand force with the second demand force, thereby selecting one of the post-filter demand force and second demand force as final demand force.

Abstract: A vehicle control apparatus is provided which is operative in an automatic engine stop mode to stop an engine automatically and in an engine restart mode to restart the engine automatically after the engine is stopped in the automatic engine stop mode so as to output a predetermined reference engine torque immediately after the engine is started. The vehicle control apparatus works to determine the travel performance of the vehicle required immediately after the engine has been restarted in the engine restart mode and control the torque outputted by the engine based on the determined travel performance so as to ensure the drivability of the vehicle after the engine is restarted automatically.

Abstract: In a system installed in a vehicle, an automatic stop of an engine is carried out when an engine automatic stop condition is met during the vehicle being decelerated. The automatically stopped engine is restarted when an engine restart condition is met before the vehicle is stopped. A vehicle speed obtaining unit obtains a vehicle speed, and a threshold determining unit determines a threshold based on a predetermined-timing value of the vehicle speed. The predetermined-timing value is obtained at a predetermined timing when or after the engine restart condition is met. The threshold is used to determine whether to enable a next automatic stop of the engine. A stop enabling unit enables the next automatic stop of the engine when the speed of the vehicle obtained after the engine restart condition is met is equal to or higher than the threshold.

Abstract: A controller stops a fuel injection when a vehicle is in a specified decelerate condition where the vehicle likely stops and an automatic stop requirement is generated. An input shaft and an output shaft of a shift transmission mechanism are directly connected with each other through a direct connector so that a driving power is transmitted from an engine to a driving shaft through a power transmitter which permits a sliding between an input shaft and an output shaft thereof. When a restart requirement is generated before the vehicle is completely stopped, the engine is restarted under a condition where the input shaft and the output shaft of the shift transmission mechanism are connected with each other by a direct connector. When the restart requirement is not generated before the vehicle is completely stopped, the input shaft and the output shaft are disconnected when the vehicle is completely stopped.
