摘要： A road surface condition is determined appropriately. A road surface determining section (84) configured to determine a road surface condition with reference to a wheel speed signal indicative of wheel speeds includes a band-stop filter (841) which acts on the wheel speed signal and has a cutoff frequency band which is changed in accordance with the wheel speed signal.

摘要： The preview damping control includes an ECU. When the vehicle is traveling within a communications disruption area in which a radio communication device is hard to communicate with a cloud, the ECU uses road surface displacement correlating information that has been stored in an on-board memory device in advance for the communications disruption area so as to perform a preview damping control.

摘要： A method to control, while driving along a curve, a road vehicle with a variable stiffness and with rear steering wheels. The method comprises the steps of: determining an actual attitude angle of the road vehicle; establishing a desired attitude angle; determining an actual yaw rate of the road vehicle; establishing a desired yaw rate; and changing, in a simultaneous and coordinated manner, the steering angle of the rear wheels and the distribution of the stiffness of the connection of the four wheels to the frame depending on a difference between the actual attitude angle and the desired attitude angle and depending on a difference between the actual yaw rate and the desired yaw rate.

摘要： A vehicle integrated control method includes determining a road surface status, determining a vehicle status, determining an integrated control mode by determining a control status of an electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status, and controlling the electronic control suspension and an in-wheel system by determining a control amount based on the determined integrated control mode.

摘要： A damping control device and a damping control method for controlling damping of a vehicle are provided. Damping control of the vehicle is performed by adaptively switching a damping mode while considering energy consumption (fuel economy, a consumption amount of a battery, and the like) according to a state of the vehicle such as a state of an interior of the vehicle, a driving state of the vehicle, and an ambient environment. That is, the state of an interior of the vehicle, the driving state of the vehicle, and the ambient environment are constantly monitored, and the damping mode is switched to a weak damping mode in the case where unnecessity of damping as strong as a current state is determined whereas the damping mode is switched to a strong damping mode in the case where necessity of stronger damping is determined.

摘要： A vehicle may include a speed sensor configured to detect a speed of a vehicle; a door operation sensor configured to detect whether a door of the vehicle is opened or closed; an ambient detection sensor configured to detect a diagonal-front or diagonal-rear vehicle approaching the vehicle; and a controller configured to perform the variable control for the damping force of the damper by using at least one of the door operation signal and the ambient detection sensor signal when the controller receives the signal of the vehicle speed from the speed sensor and the vehicle speed is within a predetermined speed.

摘要： A damper control system for a vehicle may include a damper-relative-velocity estimation module measuring a vertical acceleration of a vehicle body through a sensor mounted on the vehicle and estimating a damper velocity of a suspension based on the measured vertical acceleration, and a control module reducing movement of the vehicle body by actuating a damper using the damper velocity of the suspension estimated through the damper-relative-velocity estimation module.

摘要： A suspension system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

摘要： A twin tube damper assembly includes a main tube defining a fluid chamber. An external tube extends about the main tube defining a compensation chamber therebetween. A piston, slidably disposed in the fluid chamber, divides the fluid chamber into a compression chamber and a rebound chamber. A rod guide is disposed in the rebound chamber, attached to the main tube and the external tube, defining at least one channel in fluid communication with the rebound and compensation chambers. A piston rod extends through the rod guide and is attached to the piston. A pressure rate sensitive system, disposed in the rebound chamber, is attached to the rod guide in fluid communication with the at least one channel, the rebound chamber, and the compensation chamber for regulating the working fluid flow through the rod guide between the rebound and compensation chambers during compression and rebound strokes.

摘要： A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile and a driver actuatable input. The driver actuatable input may be positioned to be actuatable by the driver in the absence of requiring a removal of either of the hands of the driver from a steering device of the vehicle.
