    摘要： When an estimation state of a road noise value based on an angular acceleration of a wheel is a proper estimation state, it is determined whether a background noise of the vehicle is in the high background or the low background noise state according to magnitudes of the road noise value and a predetermined threshold value. When the estimation state is not the proper estimation state, it is determined that the background noise of the vehicle is in the low background noise state regardless of road noise value. When the background noise is in the high background noise state, an output of the in-vehicle actuator is set so noise accompanying an operation of the in-vehicle actuator becomes relatively large. When the background noise is in the low background noise state, an output of the in-vehicle actuator is set so that noise accompanying an operation of the in-vehicle actuator becomes relatively small.

    摘要： A control system for operating a military vehicle according to different modes includes processing circuitry that receives a user input indicating a selected mode of the different modes, and operates a driveline and a front end accessory drive (FEAD) of the military vehicle according to the selected mode. The driveline of the military vehicle includes an engine and an integrated motor generator (IMG) and the FEAD includes multiple accessories and an electric motor-generator. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and drives tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

    摘要： A control method controls a series hybrid vehicle in which a drive motor and an internal combustion engine are supported in a vehicle body via a plurality of mount members in an integrated state. The control method using a controller generates electric power using an electric power generation motor, and drives the electric power generation motor using motive power of the internal combustion engine. The control method drives a drive wheel with the drive motor using the generated electric power, and causes the drive motor to generate regenerative torque during deceleration. In the control method, the regenerative torque is generated by the drive motor such that an upper limit of the regenerative torque is restricted to a magnitude at which an engine rotational speed where resonance occurs on the vehicle body floor.

    摘要： A control device for a hybrid vehicle includes an engine operating point control unit that shifts an engine operating point to an engine operating point on an optimal fuel-efficiency operating line outside a predetermined noise generation region in which combustion sounds of an engine become noise when the engine operating point is in the noise generation region. Accordingly, when the engine operating point is in the noise generation region, the engine operating point control unit shifts the engine operating point to an engine operating point on the optimal fuel-efficiency operating line outside the noise generation region. As a result, since the engine operating point is not separated from the optimal fuel-efficiency operating line even when the engine operating point departs from the noise generation region, it is possible to curb a decrease in fuel efficiency.

    摘要： A controller for a motor vehicle powertrain, the controller being configured to control the amount of torque generated by each of a plurality of drive torque sources, each drive torque source being coupled via a respective torque transfer arrangement to a respective group of one or more wheels, the controller being configured to cause a first of the drive torque sources, during acceleration, deceleration and substantially constant speed operation, substantially continually to apply a drive torque to a first group of one or more wheels to which the first drive torque source is coupled acting in a first direction relative to a longitudinal axis of the vehicle and causes a second of the drive torque sources, during acceleration, deceleration and substantially constant speed operation, substantially continually to apply a drive torque to a second group of one or more wheels to which the second drive torque source is coupled, the direction of drive torque applied to the second group being in a second direction opposite the first such that a net drive torque applied to the first and second group in combination corresponds substantially to a predetermined drive torque demand value, the predetermined torque demand value being determined at least in part by reference to a torque demand signal received by the controller.
