A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

Aspects of the present invention relate to an actuator system for a vehicle suspension system comprising: a first actuator comprising a piston, a first upper fluidic chamber and a second lower fluidic chamber, the first and second fluidic chambers separated by the piston; a second actuator comprising a piston, a first upper fluidic chamber and a second lower fluidic chamber, the first and second fluidic chambers separated by the piston; a first hydraulic gallery fluidly connecting the first upper fluidic chamber of the first actuator and one of the first and second fluidic chambers of the second actuator; a second hydraulic gallery fluidly connecting the second lower fluidic chamber of the first actuator and the other of the first and second fluidic chambers of the second actuator; and at least one pump configured to pump fluid between the first and second hydraulic galleries.

A suspension system for a vehicle is provided. The vehicle is travelling on a substrate. The suspension system includes a plurality of dampers and a controller disposed in communication with the plurality of dampers. The controller is configured to determine that a receiving coil disposed on the vehicle is inductively receiving electrical energy from a transmitting coil. The transmitting coil is disposed remote from the vehicle. The controller is further configured to control a damping level of each of the plurality of dampers to maintain a distance between the receiving coil and one of the transmitting coil and the substrate within a predetermined range or at a constant value.

A method is provided for semi-automatically adjusting a chassis of a vehicle. The vehicle (10) assesses a state of the road by means of a sensor system of the vehicle and transmits the state of the road to a central server. A further vehicle (10) interrogates the state of the road from the server and recommends adjustment of the chassis as a function of the interrogated state of the road. The invention also relates to a device for carrying out such a method.

A first active stabilizer is installed on a main drive wheel side, and a second active stabilizer is installed on a subordinate drive wheel side. A control device performs load distribution control when a difference in actual driving force between left and right sides of a vehicle exceeds a threshold value during acceleration. A high- side is one of the left and right sides with a greater actual driving force, and a low- side is another of the left and right sides. The load distribution control includes a first mode performed when a vehicle speed is equal to or lower than a first reference value. In the first mode, the control device actuates the first active stabilizer in a direction to lift up the high- side and actuates the second active stabilizer in a direction to lift up the low- side.

In one embodiment, one or more suspension systems of a vehicle may be used to mitigate motion sickness by limiting motion in one or more frequency ranges. In another embodiment, an active suspension may be integrated with an autonomous vehicle architecture. In yet another embodiment, the active suspension system of a vehicle may be used to induce motion in a vehicle. The vehicle may be used as a testbed for technical investigations and/or as a platform to enhance the enjoyment of video and/or audio by vehicle occupants. In some embodiments, the active suspensions system may be used to perform gestures as a means of communication with persons inside or outside the vehicle. In some embodiments, the active suspensions system may be used to generate haptic warnings to a vehicle operator or other persons in response to certain road situations.

The vehicle control device of the present invention acquires characteristics of a road condition in front of a traveling vehicle based on external information; acquires vehicle behavior control variables for controlling the behavior of the vehicle based on estimated state variables of the vehicle that are obtained based on the characteristics, and control variables concerning speed of the vehicle based on the external information; acquires trajectory tracking control variables for causing the vehicle to track the target trajectory based on the target trajectory on which the vehicle travels that are obtained based on the characteristics and the estimated state variables; and outputs the control commands for controlling the suspension device, steering device, and braking and driving device based on the vehicle behavior control variables and the trajectory tracking control variables. This improves travel stability of the vehicle on a road surface on which an irregularity such as ruts exists.
