摘要:
The invention relates to a method for providing a manipulated variable for an actuator (4) of an active chassis of a motor vehicle (2), wherein the manipulated variable in the event that a value for a projected variable, which is dependent upon a height profile of the terrain to be travelled by the motor vehicle (2), is available, is configured from a combination of a Skyhook variable, which is dependent upon a movement of a structure of the motor vehicle (2), and the projected variable, and wherein the manipulated variable is configured from a combination of a soft-spring variable, which is dependent upon a wheel-suspension of the motor vehicle (2), and the Skyhook variable, if no value for the projected variable is available.

A bicycle component for an at least partially human-powered bicycle has a shock absorber device. The shock absorber device includes a damper device which can be controlled by a control device. A detection device is provided with a sensor device for receiving a signal. The sensor device is arranged on at least one component of the bicycle which is pivoted in the case of a steering movement. The detection device is suitable for detecting, and is designed to detect, the difficulty in the terrain as a function of the acquired signal, and is configured to control the damper device as a function of the detected difficulty in the terrain, with the result that a damping property of the damper device can be adjusted by way of a signal of the detection device.

A distance indicating system includes a transmitting portion, a transceiver spaced a distance from the transmitting portion, and a receiving portion supported in spaced relation to the transceiver. The transmitting portion broadcasting a first electromagnetic wave. The transceiver receiving the first electromagnetic wave and transmitting a second electromagnetic wave to the receiving portion. The transceiver is operative to modulate the second electromagnetic wave in relation to an input to communicate a signal, data or information, such as the distance between the transmitting portion and the transceiver, an acceleration input, a pressure level or a temperature reading.

A distance determining system includes a first transceiver and a second transceiver spaced a distance from the first transceiver and inductively coupled thereto. The first transceiver outputs a first electromagnetic wave. The second transceiver receives the first electromagnetic wave and outputs a second electromagnetic wave, which is received by the first transceiver. One of the first and second transceivers determines a distance therebetween based at least in part upon the elapsed time of travel of the first and second electromagnetic waves. An air spring assembly can include such a distance indicating system. A method of determining a distance is also included.

The invention is directed to an air spring arrangement having a device for making ultrasonic distance measurements. An ultrasonic sensor, which is built into an air spring (2) for making measurements, can be disturbed when high frequency sonic oscillations occur when filling and venting the air spring. An air supply line (8) is disposed between the air spring (2) and a source of compressed air (30). To prevent the above disturbing frequencies, the air supply line (8) includes an air connecting pipe stub (10) which is lined with a net-shaped layer (16) on its inner wall surface. The layer (16) is preferably a plastic mesh. The filaments (18) of the mesh-shaped layer (16) are slightly inclined to the longitudinal center axis (28) of the pipe stub (10).
摘要:
An apparatus and method for controlling the undercarriage of a vehicle with means for adjusting vehicle parameters, such as, for example, the spring travel or the spring constant, in accordance with computed control signals. A signal receiving means receives signals from the environment of the vehicle and converts the signals into environmental signals. A signal processing means determines vehicle-related data from the environmental signals and a computing means computes the control signals for the vehicle control system with the aid of the vehicle-related data.

Suspension system for controlling switching attenuation forces at front wheels and rear wheels. A road surface sensor is provided under a front side of a vehicle body and moves so as to displace a road surface detecting position forwardly of the vehicle body. At the time of an intermediate speed, the road surface sensor itself is displaced forwardly of the vehicle body by an angular displacement apparatus. At the time of a high speed, the road surface sensor itself is further angularly displaced forwardly by an angle variable apparatus in a maximum displacing state to move the road surface detecting position forwardly. A delay time is calculated as required, and an attenuation force switching signal is outputted to the front and rear wheel suspensions, and a timing for at least the front wheel to arrive at the road surface detecting position is always brought substantially into coincidence with the timing for switching the attenuation force of the front wheel suspension by considering the delay time of the control system. Thus, the road surface sensor is suitably displaced and angularly displaced, thereby to optimize detection of a road surface and always switch suspension characteristics relative to a delay of a whole control system at an optimum timing in a whole travel area.
