    Abstract: A motor control system includes: a converter; two inverters; two alternating-current motors; and a control unit. The control unit is configured to control the system voltage by feedback of a current phase of a current vector of motor current of each of the motors on a d-q coordinate plane so that rectangular wave control of at least one of the first and second motors is performed in a state where the current phase is an optimal current phase, wherein the control unit selects, as a subject of the feedback, the current phase of one of the motors that is larger than the other motor in system voltage deviation obtained based on the current vector.

    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: Target rotation speed at a reference point set at TDC slightly preceding a target stop position of engine rotation is set. A target trajectory of an engine rotation behavior extending since an engine rotation stop behavior starts until the target rotation speed at the reference point is reached is calculated based on the target rotation speed at the reference point and an engine friction. Torque of an alternator is controlled to conform the engine rotation behavior to the target trajectory during the engine rotation stop behavior. Generation of the torque of the alternator stops at a position preceding the reference point by a predetermined crank angle. Therefore, the torque of the alternator is controlled such that an energy deviation between the target trajectory and the engine rotation behavior becomes zero at the position preceding the reference point by the predetermined crank angle.
