A control system (300) for controlling an active suspension system (104) of a vehicle (100), the control system comprising one or more controller (301), wherein the control system is configured to: detect (1004) a ramp (202) approached by an overhang of the vehicle; and in dependence on detecting the ramp, control (1020) the active suspension system to modify a relative ride height between a leading ride height at a set of leading wheels (FL, FR) of the vehicle and a trailing ride height at a set of trailing wheels (RL, RR) of the vehicle, to increase a ramp angle (, ) of the vehicle relative to the ramp.

An in-vehicle stable platform system employing active suspension and a control method thereof is provided. The system includes a vehicle body, an in-vehicle stable platform, an inertial measurement device, an electronic control device, a servo controller set, multiple wheels, and suspension servo actuation cylinders and displacement sensors respectively corresponding to the wheels. The wheels are divided into three groups, which form three support points. The heights of the three support points are controlled to control orientation of the vehicle body. An amount of extension/retraction of the suspension servo actuation cylinders required to cause the in-vehicle stable platform to return to a horizontal level is calculated according to a measured pitch angle and a roll angle of the in-vehicle stable platform, and when a vehicle travels on an uneven road, the extension/retraction of each suspension servo actuation cylinder is controlled to cause the in-vehicle stable platform to be horizontal.

A transport trailer for transporting an elongated body features a containment structure supported on a trailer frame so as to define a hollow interior suitable to receive the elongated body therein. The containment structure includes a receptacle portion defining a receptacle for containing a noxious substance carried on the body, an access opening at a top side of the receptacle portion for accessing the interior of the containment structure, and a closable lid carried on the receptacle portion. The lid is movable relative to the access opening between an open position in which the access opening is unobstructed and a closed position in which the access opening is covered so as to close the containment structure. There also are provided load bearing surfaces within the containment structure which are supported on the frame and anchoring locations on an inside of the containment structure for receiving straps to secure the body.

An auto-leveling drive axle device for a wheel tractor, and leveling method. The device comprises a transmission device and a leveling device. The device of the present invention changes only a vertical position of a drive axle with respect to a wheel, and a wheel shaft distance and wheel center spacing are not changed, thus improving traveling stability of a vehicle.

A passenger vehicle provided with a steering handle (15) and configured such that an attitude angle of the driver seat surface (14a) relative to a horizontal reference plane is changeable, so that a first attitude changing operation switch (25) and a second attitude changing operation switch (26) for changing the attitude angle are disposed in such positions as to be operable with a thumb of the driver of the vehicle from a steering handle grip (18) of the steering handle (15).

A system for improving performance or efficiency of operation of a vehicle. The system includes a sensor configured to detect current vehicle speed data and current vehicle slope data. The system includes a pedal control unit configured to detect current pedal position data. The system includes an electronic control unit (ECU) configured to determine expected driving power demand based on current vehicle speed data and vehicle slope data. The ECU is configured to determine detected driving power demand based on current pedal position data. The ECU is configured to detect a drafting condition when the expected driving power demand exceeds the detected driving power demand. The ECU is configured to adjust, when the drafting condition is detected, at least one of a chassis control setting, an engine control setting, a transmission control setting, or a hybrid control setting to improve performance or efficiency of operation of the vehicle.

A system and method for utilizing an active valve customizable tune application is disclosed. The system includes a mobile device having a memory, an active valve tune application, and at least one processor. The processor initiates the active valve tune application, receives, from a database, an active valve suspension tune having a number of performance range adjustable settings, and receives user related input information. At least one of the performance range adjustable settings is modified based on the received input information to generate a modified active valve suspension tune. The system includes an active suspension of a vehicle, wherein the modified active valve suspension tune is implemented by the active suspension.

A wheelchair including a base assembly that has a first side and a second side. At least one caster and a drive wheel are mounted to each of the first and second sides. The wheelchair includes a seat assembly having a seat and a backrest and an actuator assembly having a plurality of actuators. Each actuator can expand and retract and includes a first end pivotably connected to the base assembly and a second end pivotably connected to the seat assembly. The actuator assembly allows for at least four degrees of movement of the seat assembly with respect to the base assembly. The wheelchair includes a computer that is connected to the actuators and that controls the movement of the actuators. The computer moves the actuators to vary the position of the seat assembly with respect to the base assembly.

Disclosed in the present disclosure are a lift axle control method for a vehicle and a lift axle control system for a vehicle, wherein the method comprises the following steps: step 1) acquiring a load M of the vehicle; step 2) judging whether it needs to lower the lift axle according to the load, and if so, controlling the vehicle to lower the lift axle, and entering into step 3); otherwise, returning to step 1); step 3) calculating an optimal position of lifting the lift axle, controlling the vehicle to lift the lift axle at the optimal position, and entering into step 4); step 4) calculating an optimal position to lower the lift axle, controlling the vehicle to lower the lift axle at the optimal position, and then returning to step 3). The method of the present disclosure can reduce the damage to the road surface and achieve the economy of fuel consumption during running of the vehicle.
