AUTOMOTIVE SUSPENSION ASSEMBLIES
A suspension assembly includes a shock absorber arranged to damp linear motion of a piston portion relative to a surrounding cylinder portion. A lead screw is disposed within the shock absorber for conversion between linear kinetic energy and rotational kinetic energy. The suspension assembly also includes an electric motor displaced externally from the shock absorber, for conversion between rotational kinetic energy and electricity, and a transmission arrangement disposed outside the shock absorber, mediating between the shock absorber and the motor, and configured to transfer a resistance torque from the motor to the lead screw so as to modulate the damping of the linear motion.
Suspension controller and sensor network for ride height control with air suspension
A system for controlling vehicle ride height include a suspension controller. The suspension controller is coupled to a motion sensor attached to a chassis of a vehicle and additional motion sensors each attached to a suspension member of the vehicle that pivots relative to the chassis. The suspension controller receives motion sensor data from the motion sensors and determines relative angular position of each suspension member as a function of motion sensor data received from the motion sensor attached to the chassis and motion sensor data received from the motion sensor attached to the suspension member. The suspension controller adjusts an air suspension based on the relative angular position. Other embodiments are described and claimed.
Central joint device for chassis components
A central joint device for chassis components (2), particularly three-point link, is suggested. The central joint device comprises at least one housing unit (3), at least one joint pin unit (4) which is movably supported at least partially inside of the housing unit (3), and at least one sensor unit (5), particularly a magnetic sensor unit, which is provided for contactless detection of roll motions and pitch motions of the housing unit (3) and of the joint pin unit (4) relative to one another. The sensor unit (5) comprises at least one encoder element (6) and at least one sensor element (7). The encoder element (6) and the sensor element (7) are arranged to be spaced apart from one another and movable relative to one another.
LANE KEEPING SYSTEM FOR AUTONOMOUS VEHICLE IN WIND CONDITIONS USING VEHICLE ROLL
A lane keeping system for a vehicle includes a first roll angle sensor configured to provide a first signal indicative of dynamic vehicle body roll. A second roll angle sensor is configured to provide a second signal indicative of an angle between vehicle sprung and unsprung masses. A lane keeping system (LKS) controller is in communication with the first and second roll angle sensors. The LKS controller is configured to discern a vehicle roll angle in response to the first and second signals based upon effects of a lateral wind force on the vehicle. The LKS controller is configured to produce a correction in response to the determined lateral wind force effects to maintain the vehicle along a desired path.
SUSPENSION CONTROLLER AND SENSOR NETWORK FOR RIDE HEIGHT CONTROL WITH AIR SUSPENSION
A system for controlling vehicle ride height include a suspension controller. The suspension controller is coupled to a motion sensor attached to a chassis of a vehicle and additional motion sensors each attached to a suspension member of the vehicle that pivots relative to the chassis. The suspension controller receives motion sensor data from the motion sensors and determines relative angular position of each suspension member as a function of motion sensor data received from the motion sensor attached to the chassis and motion sensor data received from the motion sensor attached to the suspension member. The suspension controller adjusts an air suspension based on the relative angular position. Other embodiments are described and claimed.
Torsion device
A torsion device comprising: a first part comprising a first resilient torsion member including: a first support end; a first free end spaced from the first support end; and a first engagement region; a second part comprising a second resilient torsion member including: a second support end; a second free end spaced from the second support end; and a second engagement region; wherein the second part is rotatable relative to the first part about an axis of rotation (A) between a first angular position and a second angular position, and the first and second torsion members are configured to urge the first and second engagement regions together to cause flexure of at least one of the first and second resilient torsion members as the second part rotates relative to the first part from the first angular position to the second angular position.
Vehicle cruise control device
Provided is a vehicle cruise control device 10 that performs trajectory control for causing a vehicle to travel along a traveling road by steering vehicle wheels. The vehicle cruise control device includes: a roll control device (active stabilizers 56 and 58, etc.) configured to control a lateral-direction inclination angle of a vehicle body; and an inclination angle estimation device (a roll rate sensor 72, a stroke sensor 74i, etc.) configured to determine a lateral-direction inclination of a traveling road. When the trajectory control is executed in a situation in which the vehicle travels on a laterally inclined traveling road (S150, S250, S300, S500), the lateral-direction inclination angle of the vehicle body is controlled by the roll control device so that the lateral-direction inclination angle of the vehicle body is greater than 0 and smaller than the lateral-direction inclination angle of the traveling road (S450).
Vehicle provided with a suspension and an electromechanical rotary device for controlling the suspension, and method for controlling motion of a vehicle suspension
A vehicle is provided which has a vehicle body, at least one hub of a wheel, and a suspension connecting the hub to the vehicle body. The suspension has a suspension arm hinged to the vehicle body and to the hub, a spring, and an electromechanical rotary actuator operable between an active adjustment condition and a damping condition of the motion of the suspension, via a leverage.
