An all terrain vehicle may include a braking system comprising a hydraulic and electric controller unit (HECU) operably coupled to the plurality of ground-engaging members. The HECU may receive sensor information from the one or more sensors and determine whether the all terrain vehicle is encountering a wheel locking event based on the sensor information. The wheel locking event may indicate the plurality of ground-engaging members are unable to turn. The HECU also may determine whether the all terrain vehicle is encountering a turning event based on the sensor information and operate in an HECU intervention mode based on an indication that the all terrain vehicle is encountering the wheel locking event and the turning event. The HECU intervention mode permits the HECU to control the plurality of ground-engaging members based on steering input.

Operating modes using a braking system for an all terrain vehicle

A damping control system is provided for an off-road recreational vehicles having a suspension located between a ground engaging member and a vehicle frame and including at least one adjustable shock absorber having an adjustable damping characteristic based on an input from a sensor.

Systems and methods of adjustable suspensions for off-road recreational vehicles

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

Vehicle having adjustable compression and rebound damping

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.

Vehicle having adjustable suspension

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.

Adjustable vehicle suspension system

An all-terrain vehicle may include a frame and a plurality of ground-engaging members supporting the frame. The all-terrain vehicle may further include a powertrain assembly supported by the frame and shiftable transmission supported by the frame and operably coupled to the powertrain assembly. The all-terrain vehicle may also include a display, a back-up camera, and a controller supported by the frame. The controller may be configured to receive a signal from the shiftable transmission corresponding to the shiftable transmission being in a gear of the plurality of gears other than a reverse gear. Further, the controller may be configured to determine the all-terrain vehicle is moving backwards and send an activation signal to the back-up camera to display images of the back-up camera on the display.

Systems and methods for operating an all-terrain vehicle

Systems and methods for detecting a vehicle hazardous condition of a recreational vehicle and activating a distress mode of the recreation vehicle in response to detecting the vehicle hazardous condition.

Systems and methods for vehicle hazardous condition detection

A fuel system comprising a fuel tank, a mixing volume configured to mix fuel vapor and air, the mixing volume comprising an outlet configured to be fluidly coupled to an engine, and a fuel vapor line configured to fluidly couple the fuel tank to the mixing volume.

Evaporative emissions control for a vehicle

A diagnostic system of a vehicle for diagnosing a drive belt of a continuously variable transmission. A diagnostic circuit detects or predicts a fault of the drive belt based on an operating parameter received from a sensor associated with the vehicle during a predetermined diagnostic period.

Diagnostic systems and methods of a continuously variable transmission

A power steering system reduces or prevents an unintended jerking of a steering input device due to an unintended torque being input into the power steering system from an output of the power steering system. The unintended torque may be determined based on an acceleration of a motor of the power steering system.

Vehicle steering systems and methods

A utility vehicle is configured for independently controlling torque at each of the ground-engaging members.

Torque vectoring for utility vehicles

A suspension system for a vehicle and method for operating the same includes a shock absorber housing having a longitudinal axis, a spring disposed around the shock absorber housing, a retainer collar disposed around the shock absorber housing and an actuator engaged to the retainer collar. The actuator moves at least a portion of the retainer collar to move the spring in a direction corresponding the longitudinal axis. A switch generates a ride height position signal. A controller is coupled to the actuator and the switch. The controller controls a position of the actuator in response to the ride height position signal.

Suspension pre-load adjustment system

Suspension systems for recreational vehicles are disclosed. The suspension systems may include at least one adjustable member coupling a sway bar to respective suspensions. The suspension systems may include a torque actuator associated with a sway bar.
