A vehicle includes a frame, and at least one front and rear wheel. The total number of front and rear wheels is at least three. The vehicle includes a mechanism for driving at least one of the front and rear wheels, a seat for a driver, and at least one fall prevention element to prevent, in a closed position of the fall prevention element, a driver from falling off the seat. In an open position of the fall prevention element, a driver can freely take a seat from the outer side of the vehicle via the space which, in the closed position, is occupied by the fall prevention element, or can step out of the vehicle; the fall prevention element slides between the open and closed positions.

A suspension system for a vehicle includes a shock absorber unit operably coupled between a vehicle body and a wheel carrier. The shock absorber unit includes a first damper unit having a first cylinder chamber, a second damper unit having a second cylinder chamber, a first piston connected to a first piston rod, a second piston connected to a second piston rod, and an adjusting unit. The first and second cylinder chambers may each be filled with a fluid. The first and second cylinder chambers may be formed in a common cylinder unit and sealed off from one another. The first and second piston rods may be arranged axially displaceable in the first and second cylinder chambers, respectively. The first piston rod is operably coupled to the vehicle body and the second piston rod is operably coupled to the wheel carrier. Damping actions of the first and second damper units are changed independently of one another by the adjusting unit.

A vehicle control device includes an acquisition unit configured to acquire detection information in a current traveling state and position information indicating a current position of a vehicle, a transmission unit configured to transmit traveling information in which the detection information and the position information are associated with each other to an external management device, a reception unit configured to receive changed specification information of the vehicle transmitted when the management device determines that specifications of the vehicle need to be changed, and a control unit configured to change the specifications of the vehicle corresponding to the specification information and reflect the changed specifications in traveling control. The specification information includes specifications changed based on comparison between first traveling information that is current traveling information of the vehicle and second traveling information obtained when the vehicle has previously traveled at a same position.

An electronic control suspension system for a vehicle is proposed. The electronic control suspension system includes a detection unit detecting information on a road in front of the vehicle, an electronic control suspension which damping force is controlled by current, and a control unit is configured to adjust the damping force of the electronic control suspension according to the information detected by the detection unit.

Disclosed is an automatic vehicle suspension tuning system. The system has a control module to receive user input, an ECU with a processor and a memory, one or more road condition sensors, and one or more controllable suspension system components. The ECU controls the adjustments of the controllable suspension system component in response to user input to the control module as well as input from the road condition sensors during operation of the vehicle. A method of tuning a controllable suspension system component is also disclosed.

A controller includes a calculation processing portion configured to make a predetermined calculation based on an input vehicle state amount and output a target damping force, and a damping force map configured to acquire a control instruction value for controlling a variable damper based on the target damping force. The calculation processing portion makes the calculation using a learning result that is acquired by causing the calculation processing portion to learn pairs of a plurality of target amounts acquired using a predetermined evaluation method prepared in advance with respect to a plurality of different vehicle state amounts as pairs of pieces of input and output data.

Techniques for using ball joint sensor data to determine conditions relevant to a vehicle are described in this disclosure. For example, in one example, the ball joint sensor data may be used to determine estimated steering data. The estimated steering data may be directly used to navigate through an environment, such as by the vehicle relying on the estimated steering data when planning, tracking, or executing a driving maneuver. Also, the estimated steering data may be used to verify the reliability of other steering sensor data used to navigate through the environment.

A personal mobility and a control method are provided. The personal mobility includes: a main body; a front wheel mounted on the front end of the main body; a pair of rear wheels mounted on the rear end of the main body; an actuator configured to adjust a distance between the pair of rear wheels; an image data device mounted on the personal mobility and having a field of view outside of the personal mobility, the image data device configured to acquire image data; and a controller configured to determine at least one of user state information or external environment information based on the image data, and control the actuator to adjust the distance between the pair of rear wheels based on at least one of the user state information or the external environment information.

A vehicle control device includes a vertical VSE, a riding comfort control logic, a planar VSE, a steering stability control logic, a command limiting unit, a control command selection unit. The command limiting unit acquires specifications related to a traveling of a vehicle such as, for example, a slip rate and a four-wheel independent braking/driving force control flag through a CAN. The command limiting unit limits a variable range of a damping force generated by a suspension device provided between a vehicle body and wheels of the vehicle based on the specifications related to the traveling of the vehicle to obtain a first command value. The command limiting unit outputs the obtained first command value to the control command selection unit.

The present disclosure relates to a mobility device having an active suspension function and method therefor. The mobility device may include: a suspension module located between a wheel and a sash of the mobility device and configured to perform a suspension function to the mobility device; a sensor module comprising an inclinometer and a ride height sensor; and a communication module configured to support vehicle-to-everything (V2X) communication. The communication module may be configured to provide, as first suspension module control information for a subsequent mobility device, road surface information obtained by the inclinometer and the ride height sensor during driving of the mobility device based on the V2X communication.
