    摘要： This disclosure is generally directed to systems and methods for avoiding certain undesirable vehicle operations when a vehicle having a dual vehicle propulsion system is parked inside a confined space. For example, it is desirable to avoid operating an internal combustion engine of a hybrid electric vehicle when the hybrid electric vehicle is parked inside a garage because the internal combustion engine may produce undesirable gaseous emissions, particularly during start up. In an example embodiment, this issue is addressed by a computer of the vehicle defining a geofence that encompasses the garage. The computer disables the operation of the internal combustion engine when the hybrid electric vehicle is located inside the geofence but allows operation of an electric motor of the hybrid electric vehicle for moving the vehicle out of the geofence. The computer enables operation of the internal combustion engine when the vehicle has moved outside the geofence.

    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： Disclosed is a control method for an internal combustion engine (3) including a power generation motor (4) driven by a power of the internal combustion engine (3) and a damper (30) provided between the internal combustion engine (3) and the power generation motor (4) in a power transmission path, wherein a maximum value of a torque fluctuation generated in an event of a misfire occurring in a cylinder of the internal combustion engine (3) is larger than a value at which a displacement of a main damper (30a) of the damper (30) is allowed to be suppressed to be smaller than a displacement at which abutting occurs on a first stopper (31a) by a counter torque of the power generation motor (4), and the control method includes limiting a torque (Te) of the internal combustion engine (3) within a range in which a displacement of the main damper (30a) is allowed to be controlled to be smaller than a displacement at which abutting occurs on the first stopper (31a) by a counter torque of the power generation motor (4).

    摘要： By the vehicle control method, in a vehicle provided with wheel, a sensor that acquires rotation speed of the wheel, and a sound generation device that generates sound as the sound generation device is driven, the angular acceleration of wheel is obtained from the rotation speed acquired by a sensor, and a sound generation device is controlled such that the generated sound becomes louder when conditions are met. Cases in which the angular acceleration is high are included in the conditions.

    摘要： A hybrid vehicle control method is provided for a hybrid vehicle having an engine and a generator directly connected via a gear train having a plurality of gears that are engaged with each other. In this hybrid vehicle control method, a prescribed torque is continuously applied to the generator upon determining the engine is in a rotating state such that a transmission torque of the gear train does not continuously fluctuate above and below zero torque. Preferably, in one embodiment, the prescribed torque continuously applied to the second motor/generator is a negative torque value during a power generation operation in which the generator is rotated by the engine and is a positive torque value during a motoring operation in which the engine is rotated by the generator.

    摘要： A method, system, and/or computer program product mitigate vibration caused by sympathetic resonance in a structure that is physically proximate to a machine. One or more processors, based on readings from a resonance sensor, detect vibration caused by sympathetic resonance in a structure that is physically proximate to the machine. One or more processors then direct a machine component controller to adjust the machine component in order to mitigate the vibration.
