摘要： A vehicle active vibration control (AVC) system includes a vehicle having at least an engine, a transmission, a controller area network (CAN) bus, a frame, and a cabin. The vibration control devices (120) are distributed about the frame, with each device including a circular force generator (CFG) (122). At least one sensor is positioned on the frame to detect and measure a noise and/or vibration within the cabin. Each sensor creates an electronic data signal and electrically communicates with a corresponding vibration control device. Each vibration control device receives an electronic data signal from a corresponding sensor and vehicle data from the CAN bus. Each vibration control device processes the electronic data signal and the vehicle data. The CFG of each vibration control device generates a vibration canceling force having a magnitude and phase that attenuates noise and/or vibration within the cabin.

摘要： A vehicle vibration control system (VCS) includes a vehicle having at least an engine, a transmission, a frame, a steering column with a steering wheel attached, a passenger cabin, and a controller area network (CAN) bus. The vibration and noise in the cabin and in or around steering column are bothersome to passengers in the passenger cabin. Linear force generators (LFGs) are used to control the noise and vibration in or around the steering column and/or steering wheel. Circular force generators (CFGs) are used to control noise and vibration in the passenger cabin. Sensors are used to measure the noise and vibration.

摘要： Systems, devices, and methods for active vibration control using circular force generators. In one aspect, a vehicle includes a vehicle frame, a cabin, an engine, and a number of vibration control devices mounted on the vehicle frame. Each vibration device includes a circular force generator comprising at least one mass and at least one motor configured to rotate the mass. The vibration control devices are configured to perform active vibration control to reduce noise and/or vibration within the cabin resulting from the engine deactivating a subset of cylinders in operation.

摘要： An electric vehicle emulation system and method is provided using at least one force generator (FG) to induce a vibration emulating the feel of an internal combustion engine in an all-electric, hybrid-electric, or alternative fuel vehicle. The FG may be a circular FG (CFG), a lincar FG (LFG), or a combination of both CFGs and LFGs.
