A pet mode door and suspension control system and method includes determining whether a door control action has occurred with respect to a door on the vehicle. When determined that the door control action has occurred, the system and method further includes determining whether a pet mode control action is needed. When determined that the pet mode control action is needed, a suspension control command is sent to suspension control system for raising and/or lowering at least one side of the vehicle and a door control command is sent to a power control unit for opening or closing the door in accord with the door control action.

Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.

The present invention is a hybrid crossover between an automobile and a motorcycle that is able to take tight corners almost like a motorcycle but is driven and handled like an automobile by optionally leaning into turns with one wheel in the front and two wheels in the rear of the vehicle and passenger compartment having an accelerator and brake pedals and steered with a steering wheel and gears that can be selected via a toggle switch gear selector located in the vicinity of the steering or by a floor and/or dash mounted unit.

An active suspension system comprises at least one biasing device configured to support a body from a structure, and at least one motor. A magnetorheological (MR) fluid clutch apparatus(es) is coupled to the at least one motor to receive torque from the motor, the MR fluid clutch apparatus controllable to transmit a variable amount of torque. A mechanism is between the at least one MR fluid clutch apparatus and the body to convert the torque received from the at least one MR fluid clutch apparatus into a force on the body. Sensor(s) provide information indicative of a state of the body or structure. A controller receives the information indicative of the state of the body or structure and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the body to control movement of the body according to a desired movement behavior.

A suspension system for a vehicle may include a knuckle configured of rotatably supporting a wheel, and a lower control arm mounted along a vehicle's width direction and connecting the knuckle and a vehicle body, wherein the lower control arm may include a wheel-side end portion connected to a lower portion of the knuckle through a lower external joint, a vehicle body-side front end portion connected to the vehicle body through a front lower inner joint, and a vehicle body-side rear end portion connected to the vehicle body through a rear lower inner joint, wherein one of the vehicle body-side front and rear end portions is connected to a portion of the vehicle body through a compliance control arm.

A milling machine includes a milling assembly having a housing to which left and right end gates are attached, a controller, a right front lifting column, a left front lifting column and a rear lifting column. Elevation sensors are located at the front and rear of each of the end gates. The controller is operatively attached to the elevation sensors and to linear actuators within the lifting columns of the milling machine. The elevation sensor that is located at the front end of the right end gate will provide feedback to control the position of the right front lifting column, and the elevation sensor that is located at the front end of the left end gate will provide feedback to control the position of the left front lifting column. The elevation sensors that are located at the rear ends of the end gates are available, as selected by the operator, to provide feedback to control the positions of one of the right and left front lifting columns, as well as the rear lifting column.

A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two support plates are slidably guided on the support base toward and away from each other. A pair of wheel assemblies is provided, wherein a wheel assembly is mounted to an end of each of the support plates remote from the other support plate such that a distance between the wheel assemblies varies with movement of the support plates on the support base. A pair of drive links is provided wherein a drive link is joined to each of the support plates. A drive mechanism is joined to the drive links and configured to selectively move the support plates toward or away from each other.

An exemplary energy delivery system includes a housing. The housing includes a linear motor including a translational member and an electromagnetic field generating member. Energization of the electromagnetic field generating member induces translation of the translational member along a longitudinal axis of the linear motor. The housing further includes a first cylinder including a first chamber and a movable first piston and a second cylinder including a second chamber and a movable second piston. The first and second cylinders are coupled in-line with the linear motor within the housing and translation of the translational member along the longitudinal axis translates the first piston within the first chamber in a first direction and translates the second piston within the second chamber in a second direction opposite the first direction.
