A recently granted patent (Publication Number: US11884117B2) discloses a novel recreational vehicle design that incorporates a sophisticated system of adjustable shock absorbers controlled by sensors and a central controller. The vehicle features a frame supported by ground engaging members and a plurality of suspensions, each equipped with adjustable shock absorbers. An onboard sensor provides acceleration data to the controller, which then determines the vehicle's orientation and adjusts the damping characteristics of the shock absorbers accordingly. For instance, when the vehicle is positioned on a hill in a lateral direction, the controller leans the vehicle into the hill by adjusting the shock absorbers.

Furthermore, the recreational vehicle includes an operator interface for mode selections, with a specific "rock crawler mode" triggering adjustments based on user input. The controller also considers vehicle speed information from a second sensor, transitioning the vehicle to a different mode if the speed exceeds a threshold. Additionally, the controller analyzes longitudinal and lateral acceleration to determine pitch and roll angles, adjusting damping characteristics based on the vehicle's orientation. Different orientations, such as facing uphill or downhill, trigger specific adjustments to the shock absorbers to optimize performance. The system also accounts for the relative positions of multiple suspensions, providing tailored adjustments to individual shock absorbers based on the vehicle's orientation.
