A utility vehicle includes a rear suspension assembly which has a trailing arm generally extending longitudinally. Also, the rear suspension assembly includes an upper radius rod extending in a generally lateral direction relative to a centerline of the vehicle. Additionally, the rear suspension assembly includes a lower radius rod extending in a generally lateral direction relative to the centerline of the vehicle. The rear suspension assembly further includes a suspension member configured to control toe of the at least one rear ground-engaging member.

An in-wheel motor drive device (10) includes: a motor portion (21); a casing (43) housing a rotation transmission path from a motor rotation shaft of the motor portion to a rotating wheel; a suspending bracket (61) including an upper joining seat portion (62) joinable with an upper side suspension member (76) of a suspension device, a lower joining seat portion (64) joinable with a lower side suspension member (71) of the suspension device, and an intermediate portion (63) connecting the upper joining seat portion and the lower joining seat portion, and a fixing means (69) for mounting and fixing the suspending bracket (61) to an outer wall surface of the casing (43).

A snowmobile includes a chassis comprising a bulkhead and a tunnel, a front suspension coupled to bulkhead, a rear suspension coupled to the tunnel, and slide rails coupled to the rear suspension.

Methods, apparatus, systems and articles of manufacture are disclosed for multi-position wheel assembly mounts. An example vehicle frame disclosed herein includes apertures adjacent to each of a plurality of wheel assembly locations on the vehicle frame, and a wheel assembly mount at each of the wheel assembly locations, the wheel assembly mount having protrusions extending toward the vehicle frame and positionable in the apertures in a first position to provide a first ride height of the vehicle frame and a second position to provide a second ride height of the vehicle frame, the first ride height less than the second ride height.

A hydraulic system includes a hydraulic pump. A first hydraulic shock is coupled to a first port of the hydraulic pump. A second hydraulic shock is coupled to a second port of the hydraulic pump. A first hydraulic cylinder is coupled to the first port of the hydraulic pump. A second hydraulic cylinder is coupled to the second port of the hydraulic pump. A first valve is coupled between the first hydraulic cylinder and second hydraulic cylinder. The first valve can be actuated by a computer system or can be a ball and spring check valve. A second valve is coupled between the first hydraulic cylinder and second hydraulic cylinder. A flow direction of the second valve is opposite a flow direction of the first valve. A first piston is disposed in the first hydraulic cylinder, and a second piston is disposed in the second hydraulic cylinder.

There are provided a battery frame that is attached to a structural member on a floor back of an automobile body and accommodates a battery, and a rear suspension member assembly that is attached to rear floor side members and supports a rear suspension. The rear suspension member assembly is attached to the rear floor side members at least at right and left front-side attachment parts and right and left rear-side attachment parts. The rear suspension member assembly is attached to the battery frame at a first attachment part that is closer to a vehicle front than the right and left front-side attachment parts.

A control system for a vehicle has a powertrain system that includes electric power propulsion system and a second propulsion system, a geographical position sensing system, a geographic map database, and a controller. The controller monitors a geographic location of the vehicle determine the geographic location of the vehicle in relation to a first predefined region and a first user-identified region. The powertrain system is controlled to generate propulsion power employing only the electric power propulsion system when the geographic location of the vehicle is within the first predefined region and when the geographic location of the vehicle is within the first user-identified region. The powertrain system is controlled to generate propulsion power employing the second propulsion system when the geographic location of the vehicle is outside the first predefined region and outside the first user-identified region.

A controller controls a suspension apparatus including a variable damper that adjusts a force between a vehicle body and a wheel of a vehicle. The controller includes a first instruction calculation portion and a control instruction output portion. The first instruction calculation portion outputs a first instruction value of a damping force, which corresponds to a first target amount, using a learning result acquired from machine learning in advance by inputting a plurality of different pieces of information. The control instruction output portion limits the first instruction value and outputs it as a control instruction in a case where the first instruction value works in a direction leading to a greater vehicle state amount than a predetermined amount due to control of the variable damper based on the first instruction value.
