A technology can be realized which increases the sense of unity with a vehicle that is felt by a driver. A suspension control device, which controls the damping force of the suspension of a vehicle, comprises a target control amount calculation unit which sets a target control amount, that is referenced when controlling the damping force of the suspension, such that the period of the phase of the roll angle and the period of the phase of the pitch angle of the vehicle approach a synchronized state, such that the magnitude of the expansion-side damping force is greater than the magnitude of the contraction-side damping force on the front-wheel-side of the vehicle, and such that the contraction-side damping force is greater than or equal to the expansion-side damping force on the rear-wheel-side of the vehicle.

Included are an electromagnetic actuator which includes an electric motor configured to generate drive forces for a damping operation and a telescopic operation; an information acquirer which acquires a stroke velocity of the electromagnetic actuator; a drive force arithmetic part which includes a damping force calculator configured to calculate a target damping force and a telescopic force calculator configured to calculate a target telescopic force, and which obtains a target drive force based on the target damping force and the target telescopic force; and a drive controller which controls drive of the electric motor using the target drive force. The drive force arithmetic part includes an adjuster which performs an adjustment to reduce a telescopic control amount for the target telescopic force based on the stroke velocity acquired by the information acquirer.

A multi-mode air shock is disclosed herein. The air shock includes an air spring having a primary air chamber, and a damper having an insertion end to telescope within the primary air chamber and a coupler to couple with a portion of a vehicle. An adjuster housing is fixedly coupled to an end of the air spring opposite of the damper, the adjuster housing having a secondary air chamber in communication with the primary air chamber and a mounting structure to couple with a different portion of the vehicle. There is a bulkhead with a valve to open or close the fluid communication between the primary air chamber and the secondary air chamber. The air shock also includes a tertiary air chamber in fluid communication with the secondary air chamber but not in fluid communication with the primary air chamber except via the secondary air chamber.

A dynamic weight shift suspension system for shifting the tandem axle loads on a vehicle. The system includes a first airbag connected between the drive axle of a tandem and the vehicle frame, and a second airbag connected between a tag axle of a tandem and the vehicle frame. The system also has a mechatronic control unit comprising at least one port and at least one solenoid. The mechatronic control unit is in direct fluid communication with the airbags and an air supply via fluid communication lines.

There are provided an apparatus and a method for controlling a variable axle for preventing a safety accident. An apparatus for controlling a variable axle that controls operation power to one switch which is short-circuited or opened according to a manipulation of a user, and supplies the operation power for a descent of a pusher axle, includes: the other switch having one end connected to power of a vehicle and the other end which is short-circuited or opened in response to a control signal, to thereby supply the power of the vehicle as the operation power at the time of the short-circuit; and a controller confirming whether or not the vehicle is remotely being started when an ignition of the vehicle is turned-on, and opening the other switch by the control signal in the case in which the vehicle is remotely being started as a result of the confirmation.

A system and method for adjusting a drivetrain comprising an e-axle on a vehicle comprises accessing route data and compressing the route data into a plurality of linearized segments. Each segment is determined by analyzing points along the route to determine when a set of route data points indicates an uphill, downhill, or flat segment. Using the segments, drivetrain configuration information for a vehicle and a weight of the vehicle, embodiments determine a performance plan that is tailored to the vehicle, including raising the e-axle to reduce rolling resistance on some segments and lowering the e-axle for some segments for increased power for acceleration, improved braking, or increased regenerative capabilities.
