An ECU controls the damping force at the time of the expansion movement and contraction movement of the front fork. When detecting at least that the motorcycle is in a state of making a stop and the brake hydraulic sensor shows an output of more than or equal to a predetermined value, the ECU carries out a damping force reducing control for minimizing the damping force of the front fork. The ECU takes the following sequential steps of: sensing a start of an expansion movement of the front suspension after starting the damping force reducing control, sensing a termination of the expansion movement of the front suspension, and terminating the damping force reducing control.

A method for coupling a semi-trailer with a top plate to a truck tractor with a coupling plate includes: importing a reference height profile assigning a reference gradient to different actual values for the relative height of the chassis to the rear axle of the truck-tractor; changing the relative height such that the coupling plate approaches the top plate; continuously determining actual height values and height gradients while changing the relative height, wherein an actual height value is assigned the currently determined actual height gradient; checking a coupling criterion by comparing a currently determined actual height gradient with the reference gradient, wherein the reference gradient which in the imported reference height profile is assigned to the same actual height value as the currently determined actual height gradient is applied; and, maintaining the relative height when the currently determined actual height gradient deviates from the reference gradient.

Systems and methods for modifying an attitude of a vehicle are disclosed. A user selects a trailer mode for a vehicle body. The selected trailer mode has a corresponding configuration. The vehicle determines one or more features about a trailer based on the selected trailer mode. The vehicle determines a location of a trailer hitch needed to achieve the configuration corresponding to the selected trailer mode. The location is based on the one or more features about the trailer. The vehicle actuates at least one active component in the vehicle's active suspension system to change the attitude of the vehicle body so as to cause the trailer hitch to be located in the determined location thereby causing the vehicle body to be in the selected trailer mode.

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.

Provided is a configuration capable of supplying compressed air to a pneumatic apparatus while supplying electric power to an electric vehicle. A connector is connected to a vehicle provided with an air suspension device to which compressed air is supplied, and supplies electric power supplied from an electric power supply unit to the vehicle. The connector includes a charging connection portion that supplies electric power to the vehicle, and an air supply connection portion that supplies compressed air to the air suspension device.

A method of controlling an air suspension system may include a first process of determining, by a controller, whether a current situation is a parking situation that requires reduced air pressure in an air spring, a second process of maximizing, by the controller, damping force of a shock absorber when the current situation is the parking situation that requires the reduced air pressure in the air spring, and a third process of reducing air pressure in the air spring, by the controller, by bypassing compressed air stored in the air spring to a reservoir tank.
