An automatic tilting vehicle is provided that includes left and right front wheels supported by knuckles, a steerable rear wheel, a vehicle tilting device, and a control unit. The vehicle tilting device includes a swing member, a tilt actuator for swing the swing member, and a pair of tie rods pivotally attached to the swing member and the knuckles. The control unit calculates a target lateral acceleration of the vehicle, estimates a lateral acceleration of the vehicle caused by the gyro moments of the wheels and calculates a target tilt angle of the vehicle based on a sum of the target lateral acceleration and the lateral acceleration caused by the gyro moments.

There is provided a damper control device and a suspension apparatus that are capable of effectively preventing a posture change such as pitching or rolling of the body of a vehicle. To achieve the above object, a damper control device of the present invention is designed to control a damping force of a damper in accordance with a rate of change in acceleration or a rate of change in angular acceleration. If there is a time delay in the rising of the acceleration acting on the vehicle body with respect to the driving operation being performed by the driver of the vehicle, the rate of change in the acceleration has a phase lead relative to the acceleration, and accordingly, the rate of change has only a short time delay with respect to the driving operation.

In a suspension control system (20) including a variable damper (6fl, 6fr) provided between a vehicle body and each of left and rear front wheels (2fl, 2fr), a ground contact load computation unit (31) computes a front wheel target ground contact load according to a fore and aft acceleration of the vehicle body. A ground contact load distribution unit (32) computes target ground contact loads of the left and right front wheels by varying a distribution of the front wheel target ground contact load between the left front wheel and the right front wheel according to a direction and a magnitude of the fore and aft acceleration and/or a direction and a magnitude of a lateral acceleration of the vehicle body, and a damping force computation unit (33) sets a target damping force of each variable damper according to the target ground contact loads of the front wheels.

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.

Methods and systems are provided for enabling a vehicle for which a jet pump that functions to transfer fuel from a passive side to an active side of a saddle fuel tank is degraded, to reach a desired destination by the taking of mitigating action. The mitigating action includes conducting a driving maneuver in response to an indication that the jet pump is degraded, the driving maneuver conducted in order to transfer a desired amount of fuel from the passive side to the active side. In this way, a vehicle may reach a desired destination even under circumstances where the vehicle may otherwise be unable to reach the desired destination.

A suspension system includes a first and second mass and an actuator connected with the first mass and with the second mass and configured to influence a relative movement between the first mass and the second mass. The actuator includes a tube, and a magnetic assembly disposed in the tube. The actuator is configured to generate a force between the magnetic assembly and the tube as a result of the relative movement between the two. A motor is configured to rotate the magnetic assembly relative to the tube to vary the force in a velocity-dependent relationship. The actuator may generate forces to resist or assist motion between the first and second masses.

An air suspension system which uses software logic and internal signals and/or external signals available to automatically adjust the ride height of the vehicle. The air suspension system also may respond to requests from other vehicle systems requesting a change in ride height. Signals available to the vehicle may be used to detect parking lot maneuvers (for example, a combination of low speed, high steering angle, and low lateral acceleration) and automatically begin to lower the ride height of the vehicle to a calibrated entry/exit ride height. Additionally, a camera, radar, and/or parking sensor signals are utilized to detect potential roof or undercarriage clearance issues, and automatically adjust the ride height of the vehicle. The air suspension system may also adjust the ride height of the vehicle when the electronic brake system (EBS) detects rough road, automatically increasing the ride height of the vehicle to increase ground clearance.

A suspension device includes: a hydraulic damper including a rod provided with a valve for generating a hydraulic pressure when the rod is displaced between a first liquid chamber and a second liquid chamber; and an electric damper configured to electrically displace the rod by an actuator. The electric damper includes: an outer cylinder; an inner cylinder; a piston provided on the rod and configured to stroke in the inner cylinder; and a communication passage disposed inside the inner cylinder at a central portion where the piston strokes. The communication passage establishes communication between the first liquid chamber at one axial end side of the piston and the second liquid chamber at another axial end side of the piston.

A system for a vehicle includes a memory storing a stored driver distribution profile of a driver input parameter and a stored suspension setting corresponding to the stored driver distribution profile. The system further includes a sensor to detect a current value of the driver input parameter. The system further includes a processor communicably coupled to the memory and the sensor. The processor is configured to determine a current driver distribution profile of the driver input parameter based on the current value of the driver input parameter. The processor is configured to determine a current suspension setting based on the current driver distribution profile. The processor is configured to adjust the stored suspension setting to generate a stored adjusted suspension setting corresponding to the current suspension setting.

Method for correcting a height value, measured using a height sensor, of a spring-damper unit of a motor vehicle, wherein the measured height value is corrected by a correction value that is dependent on an acceleration value if the motor vehicle is accelerated in a longitudinal and/or lateral direction, the correction value being adjusted while the motor vehicle is moving.
