A vehicle may receive sensor data captured by a sensor of the vehicle, determine that the sensor data represents an object in the environment, and determine an impact location between the vehicle and the object. The impact location may be associated with a predicted collision between the vehicle and the object. The vehicle may also determine an object type corresponding to the object and/or a characteristic of the object. Based at least in part on the impact location, object type, and/or the characteristic, a ride height of the vehicle may be adjusted.

A milling machine may have a frame, ground engaging tracks that support the frame, and an actuator that adjusts a height of the frame relative to the track. The milling machine may have a control valve that selectively controls a flow of fluid into or out of the actuator based on the current supplied to the control valve. The milling machine may have a controller that determines the amount of current required to operate the actuator at a nominal actuator velocity and supplies that current to the control valve. The controller determines a measured actuator velocity based on a time required to extend or retract the actuator by a predetermined length, and adjusts the amount of current based on the measured and nominal actuator velocities. The controller also supplies the adjusted amount of current to the control valve to adjust the height of the frame relative to the track.

A vehicle including a controlled vertical position chassis, in order to be able to be moved into a low position supported on the ground, and, associated with each wheel, a suspension arm, an arm actuator, and a safety device capable of limiting the accidental lowering of the chassis, the device being able to adopt an active state wherein the rotation of the suspension arm can be limited, the device including an actuator, a cylinder of which is mounted on the chassis and a piston of which is mounted on the suspension arm, or vice versa, the actuator defining a first chamber connected to a first and a second fluid passage through the cylinder, the second passage being connected to a first fluid pipe fitted with a safety valve.

End members are supportable along a damper housing and dimensioned for securement to flexible spring member. End members include a wall with a side wall portion including an inner side surface portion. First projections extend toward a first inner edge with a first shoulder surface portion faces a second end. Second projections extend inward beyond the inner side surface portion toward a second inner edge with a second shoulder surface portion facing a first end. Second projections are spaced axially from first projections such that a groove is formed inward of the inner side surface portion between first and second shoulder surface portions. End member assemblies including such an end member as well as gas spring and damper assemblies and suspension systems are also included.

A road milling machine includes a machine frame having a longitudinal axis. A plurality of ground engaging units support the machine frame from a ground surface. A milling drum is supported from the machine frame. An operator's station is supported from the machine frame by a support linkage configured to move the operator's station laterally between an inner position and an outer position relative to the machine frame. The support linkage includes at least one pivot link extending between the machine frame and the operator's stationand oriented to pivot about a pivot axis extending parallel to the longitudinal axis of the machine frame. The operator's station in the outer position extends laterally partially beyond the machine frame on one of the left and right edges of the machine frame, the outer position being at a higher elevation than the inner position relative to the machine frame.

Example illustrations are directed to a suspension system for a vehicle and methods. In some examples, a controller of a suspension system is configured to determine the vehicle is in a service environment, and to set a height precision mode for the suspension system based on the determination the vehicle is in the service environment. In some examples, the controller is configured to detect a suspension operating condition of the vehicle, and to change a setting associated with the suspension system based on the suspension operating condition. An example method comprises detecting, using a controller, a suspension operating condition of a suspension system of a vehicle. The method may further include changing, using the controller, a setting associated with the suspension system based upon the suspension operating condition.

A dual-axle vehicle corner assembly which may include a sub-frame, a first arm connected to the sub-frame and rotatable with respect to the sub-frame about a first arm axis, the first arm having a first axle axis about which a first wheel rotates when connected to the first arm, a second arm connected to the sub-frame and rotatable with respect to the sub-frame about a second arm axis, the second arm having a second axle axis about which a second wheel rotates when connected to the second arm, and a suspension system comprising a piston assembly interconnecting the first arm and the second arm, the piston assembly is to controllably increase and decrease a length of the piston assembly to control a distance between the first axle axis and the second axle axis.

Example illustrations are directed to a suspension system for a vehicle, which includes a controller configured to determine a roughness of a ground surface associated with the vehicle. The controller may be further configured to determine a height adjustment parameter for the suspension system based on the roughness determined, and to facilitate modification of the suspension system based on the determined height adjustment parameter. Example methods are provided, which may include determining, using a controller, a roughness of a ground surface associated with a vehicle, the roughness determined based on ride height. The method may also include determining, using the controller, a height adjustment parameter for a suspension system of the vehicle based on the roughness determined.

An apparatus for adjusting a height of a vehicle including a vehicle height adjustment unit configured to adjust a height of the vehicle; a hydraulic pressure supply unit configured to supply a hydraulic pressure supplied to a caliper from a braking device for braking of the vehicle to the vehicle height adjustment unit; and a control unit configured to control a hydraulic pressure supplied to the vehicle height adjustment unit from the braking device, by controlling the hydraulic pressure supply unit depending on whether a predetermined vehicle height adjustment condition is satisfied.

A walk-behind tractor has an increased ground clearance to define a plant receiving space that has a greater height than a conventional walk-behind tractor having a straight axle. The walk-behind tractor has trailing drop arms from a frame that carry wheel axles that result in an elevated height of a driveshaft. The elevated driveshaft increases the ground clearance for taller plants to pass therebeneath during operation of the walk-behind tractor which would otherwise be too tall to pass below a conventional straight axle walk-behind tractor.
