A side-by-side all-terrain vehicle, comprising: a vehicle body comprising a cockpit and a power compartment, the power compartment being located behind the cockpit; a powertrain comprising a power motor, the power motor being provided in the power compartment; and a power battery being provided in the cockpit, and the power battery being configured to supply power to the power motor. Thus, by using the power motor as a power source, exhaust gas emissions can be reduced, and the economic efficiency of an all-terrain vehicle can be improved. By providing the power battery in the cockpit, the interior space of the cockpit can be rationally used, so that insufficient rear space of the vehicle body is avoided, and the power battery suffers less external interference and has better usage safety.

A hybrid power system includes: an engine; a continuously variable transmission, power being transferred between the continuously variable transmission and the engine; a first transmission, power being transferred between the first transmission and the continuously variable transmission; a first main decelerator, power being transferred between the first main decelerator and the first transmission; a first half shaft, power being transferred between the first half shaft the first main decelerator; a motor; a second transmission, power being transferred between the second transmission and the motor; a second main decelerator, power being transferred between the second main decelerator and the second transmission; and a second half shaft, power being transferred between the second half shaft and the second main decelerator, one of the first half shaft and the second half shaft being a front half shaft, and the other thereof being a rear half shaft.

A multi-purpose vehicle is disclosed that includes a mode change switch for operating a travel mode of a vehicle body and a mode control device for switching the travel mode of the vehicle body in response to an operation of the mode change switch. The mode control device switches the travel mode of the vehicle body between a two-wheel engine driving mode in which only an engine is driven, a two-wheel motor driving mode in which only a motor is driven, a four-wheel hybrid driving mode in which both of the engine and the motor are driven, and an OFF-mode in which none of the engine and the motor is driven.

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.

According to one aspect, an autonomous all-terrain vehicle (ATV) may include a controller receiving a command associated with autonomous driving and monitoring components of the autonomous ATV, a location unit determining a current location associated with the autonomous ATV and a destination location associated with the command, a navigation module determining one or more driving parameters based on map data associated with a path from the current location to the destination location, and a safety logic implementing an emergency stop based on an error determined by the controller. The controller may monitor the location unit and the navigation module for the error.

A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

A hybrid power train structure for off-road vehicles (ATVs, UTVs and SSVs) uses an internal combustion engine (ICE) rotating a crankshaft through a continuously variable transmission (CVT) as a primary source of locomotion torque, but also includes a driving/generator motor which, in certain established conditions, can either provide an additional or alternative source of locomotion torque or can harvest electricity from the torque created by the internal combustion engine. The driving/generator motor is an axial flux motor of small size for its relative torque output, which can either be directly coupled to the CVT output shaft or, when additionally used as a starter motor for the ICE in an automatic ICE starting and stopping routine.

A vehicle includes a differential gear that transmits rotation of a propeller shaft to an axle. A differential lock switches the differential gear between a locked state and an unlocked state. A clutch is provided in a power transmission path between a prime mover and wheels of the vehicle. A controller controls an engaging force of the clutch during a moving start of the vehicle in accordance with which of the locked state and the unlocked state is selected by the differential gear.
