A roll control system for a vehicle capable of improving the versatility compared to the related art is obtained. A roll control system according to the invention includes: a first component connected to a right connecting device that connects a vehicle body and a right wheel; a second component connected to a left connecting device that connects the vehicle body and a left wheel; and a damper. The damper includes a first damper component and a second damper component reciprocatably connected to each other. The first component includes a first base portion rotatably held by the vehicle body, a first wheel-side arm portion rotatably connected to the right connecting device, and a first damper-side arm portion rotatably connected to the first damper component. The second component includes a second base portion rotatably held by the vehicle body, a second wheel-side arm portion rotatably connected to the left connecting device, and a second damper-side arm portion rotatably connected to the second damper component.

A pneumatic suspension system for a vehicle, in which the pneumatic suspension system includes a supply tank, a first set of air springs positioned on a first side of the vehicle; a second set of air springs positioned on a second side of the vehicle, and a dual-action dynamic valve positioned between the first set of air springs and the second set of air springs. The dual-action dynamic valve is connected to the supply tank, the first set of air springs, and the second set of air springs by a series of air hoses. The dual-action dynamic valve is adapted to supply air to either one of the first set of air springs or the second set of air springs while simultaneously exhausting air from the other one of the first set of air springs or the second set of air springs.

An adjustment system and method for adjusting a chassis property of a motor vehicle wherein an understeering sensitivity of the motor vehicle is increased upon detecting that a trailer has been coupled to the motor vehicle. A detection unit operates to detect when a trailer is attached or coupled to the motor vehicle.

At least a portion of a detecting portion of a front wheel rotation speed detector is supported on one front telescopic element of a shock absorbing device and is positioned in, as viewed in the direction of a wheel axis, an area defined by a front imaginary line which passes a front end of the shock absorbing device and which is parallel to a steering axis and a rear imaginary line which passes a rear end of the shock absorbing device and which is parallel to the steering axis in a perpendicular or substantially perpendicular direction to the wheel axis and the steering axis, an area located inwards of an outer shape of a wheel, and an area which is located outside an area defined between the front and rear telescopic elements.

A rolling type vehicle includes a pair of left and right arm members supported in a swingable manner by a vehicle body on inner sides in the transverse direction for supporting a pair of left and right front wheels in a steerable manner on outer sides in the transverse direction, respectively. A shock absorber support arm of which a central portion in the transverse direction is supported in a swingable manner by the vehicle body and is connected to the pair of left and right arm members through shock absorber units on outer sides in the transverse direction, respectively. The left and right shock absorber units are disposed on outer circumference sides of turning trajectories of the pair of left and right front wheels, respectively.

A mechanical leg comprises a frame, a retractable member, a wheel, an extension and retraction driving member, a travel driving member, an auxiliary leg, and an auxiliary wheel. The extension and retraction driving member is located on a side of the frame. The retractable member is connected to the extension and retraction driving member. The wheel is connected to the retractable member. The wheel is further connected to the travel driving member. A first end of the auxiliary leg is connected to the auxiliary wheel, and a second end of the auxiliary leg is located on the frame. The retractable member extends under the driving of the extension and retraction driving member to drive the wheel to jump. The wheel is driven by the travel driving member to move. When the auxiliary wheel contacts the ground, the mechanical leg moves with the rolling of the wheel and the auxiliary wheel.

A vehicle including a vehicle platform having a reference frame, the reference frame arranged along a longitudinal axis. A first vehicle corner module (VCM) is connected to one side of the reference frame and a second VCM is connected to an opposing side of the reference frame. The first and second VCMs are adapted for regulating motion of the vehicle. A sub-frame of at least one of the first VCM and the second VCM is disposed at a splay angle relative to the longitudinal axis.

Systems, devices, and methods are described for providing, among other things, a stand-up wheel chair having automatic stability control.

An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit is configured to independently adjust air pressure of a first side of the vehicle. The second pneumatic circuit is configured to independently adjust air pressure of a second side of the vehicle. The system is configured to establish pneumatic communication between the first and second pneumatic circuits when the air management system is not independently adjusting the adjust air pressure of the first side of the vehicle and the air pressure of the second side of the vehicle in the cross-flow mode.
