A method and apparatus are disclosed that assist a user in performing proper setup of a vehicle suspension. A user may utilize a device equipped with an image sensor to assist the user in proper setup of a vehicle suspension. The device executes an application that prompts the user for input and instructs the user to perform a number of steps for adjusting the suspension components. In one embodiment, the application does not communicate with sensors on the vehicle. In another embodiment, the application may communicate with various sensors located on the vehicle to provide feedback to the device during the setup routine. In one embodiment, the device may analyze a digital image of a suspension component to provide feedback about a physical characteristic of the component.

A surroundings monitoring apparatus includes a display control unit which displays a state where a vehicle height serving as a height of a vehicle is changing on a screen of a display portion in a case where the vehicle height is changing.

A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile and a driver actuatable input. The driver actuatable input may be positioned to be actuatable by the driver in the absence of requiring a removal of either of the hands of the driver from a steering device of the vehicle.

A system and method to select and implement a suspension tune is disclosed. The system includes a memory configured to store a plurality of suspension tunes. A suspension controller configured to implement one of the plurality of suspension tunes for at least one suspension component of a vehicle. A manually operated switch to receive a user input, the manually operated switch configured to navigate between the plurality of suspension tunes, and, based on the user input, designate a different one of the plurality of suspension tunes to be implemented by the suspension controller.

A vehicle height adjustment apparatus includes a control device. The control device controls the opening degree of the solenoid valve to allow a movement amount of the support member to reach a movement amount target value that corresponds to the vehicle height set in advance, in accordance with the weight applied to the vehicle. The control device controls the opening degree of the solenoid valve to change the movement amount of the support member based on a difference between a value based on the information related to the vehicle height and a vehicle height-related target value, on condition that the movement amount of the support member reaches the movement amount target value and the value based on the information related to the vehicle height obtained by the information obtaining device does not reach the vehicle height-related target value that corresponds to the vehicle height set in advance.

In one aspect, a suspension control system is provided for dynamically adjusting pistons located proximal to wheels of an agricultural machine to account for tire deflection or squat with varying loads. Articulation, pitch, roll and/or machine height can be determined from pressure measurements on the machine to apply such tire height corrections. For sprayers, this allows controlling clearance and suspension height to maintain the boom parallel to the ground to prevent damage.
