    摘要: Systems and methods for actively isolating a payload from a disturbance. In one example, a seat system for a vehicle includes a seat, a support structure that allows the seat to move about an axis of a pivot, a first sensor positioned to detect movement of the vehicle, a second sensor positioned to detect lateral acceleration of the pivot, an actuator configured to move the seat, and a controller configured to receive a first signal from the first sensor and a second signal from the second sensor, generate a command signal based at least on the first and the second signal to instruct the actuator to position the seat at a desired command angle, wherein the controller is configured to correct the command signal for lateral accelerations caused by steering the vehicle, and provide a force command to the actuator to move the seat at the desired command angle.

    摘要: In a control loop, a command signal is applied to physical components to cause movement of the physical components. The position of the physical components is detected and used to generate subsequent command signals. In an implementation, an integrity detection system causes an excitation signal to be injected onto the command signal to cause movement of the physical components at an excitation frequency. This movement is detected in the physical system control loop and isolated by the integrity detection system. If the integrity detection system fails to detect energy in the excitation frequency band, a failure of at least one component of the control system is inferred.

In one example, a seat system for a vehicle includes a seat, a support structure including an actuator configured to move the seat about a pivot axis at a command angle, a sensor positioned to detect vehicle movement, and a controller configured to determine a vehicle roll angle based on an input from the sensor, generate a variable gain based at least on a vehicle roll acceleration determined from the input, wherein the variable gain modulates a gain of a band-pass filter having a fixed bandwidth, generate a command signal based at least on the vehicle roll angle, the controller configured to adjust a magnitude of the command signal relative to an amplitude of the input and apply the band-pass filter, and provide a force command to the actuator to move the seat at a desired command angle.

    摘要: An active vibration isolation system for a motor vehicle seat that is adapted to be occupied by a user, includes an active suspension system that supports the seat above a floor of the motor vehicle, where the suspension system comprises at least one actuator that can be controlled to move the seat up and down in the direction of a vertical axis, a first sensor system mounted to the vehicle and that is adapted to sense vehicle height position changes along or parallel to the vertical axis, a second sensor system that is adapted to determine the seat translational position along or parallel to the vertical axis, and a controller that, in response to the first and second sensor systems, is adapted to provide control signals to the active suspension system that cause motions of the seat that are designed to control the height of the user's head or torso as the vehicle undergoes translations along the vertical axis.

    摘要: Systems and methods for improving ride quality of an active payload support system. In one example, a seat system for a vehicle includes a seat, a support structure including an actuator configured to rotate the seat about an axis of a pivot, a first sensor positioned to detect movement of the vehicle, and a controller configured to receive a first input from the first sensor, determine a cornering lateral acceleration of the vehicle in a direction perpendicular to an axis parallel to a direction of travel of the vehicle around a turn, the cornering lateral acceleration determined based at least on the first input, generate a command signal based at least on the cornering lateral acceleration to instruct an actuator to rotate the seat about the axis of the pivot in a direction of the turn, and provide a force command to the actuator to move the seat.
