摘要： A vehicle excitation testing system and method can include a device for simulating a vehicular motion and vehicular vibration and then measuring response. The system is designed to test front and/or rear wheel sections of a vehicle. The testing system can include a vehicle suspension system including a wheel and chassis, an excitation actuator connected to the suspension system, and a dummy or a real vehicle body linked to the suspension system and having a frame. The frame can be positively attached to the ground surface or floor or other similar isolated and stable base surface. Measuring devices can be connected to the frame, suspension and/or wheels. When the vehicle is excited to simulate road and other conditions, the wheels, suspension system and the vehicle body vibrate. Measurement of these transmitted vibrations can be studied in order to determine how to best control unwanted or unnecessary vibrations in the vehicle.

摘要： A narrow band feedback control system is provided to mitigate a disturbance within a predetermined bandwidth that is received by an electric power steering (EPS) system within a vehicle. A torque sensor calculates a torque value associated with the disturbance applied to the EPS system, the torque sensor outputs a torque signal related to the torque value. A filter receives the torque signal, filters the torque signal to the bandwidth associated with the external disturbance, and outputs a filtered torque signal. An amplifier receives the filtered torque signal, adjusts the gain of the filtered torque signal, and outputs a filtered, amplified torque signal. A logic module receives the filtered, amplified torque signal, generates a counter torque signal that is an inverse of the filtered, amplified torque signal and outputs the counter torque signal to the EPS system to mitigate the torque received from the external source.

摘要： A method and system for determining fluidborne noise characteristics of a fluid power pump. The system includes the pump, a reference pipe fluidly connected to a discharge of the pump, three pressure sensors disposed within the reference pipe at predetermined spacings from each other and the pump, first and second loading valves, and a calculating and analysis assembly. The loading valves are selectively and alternatingly actuated to pressurize fluid contained in the system. The calculating and analysis assembly receives signals from the pressure sensors and signals indicative of the rotational speed of the pump. The calculating and analysis assembly uses these signals, together with the known physical characteristics of the reference pipe and the system fluid, to determine the source flow ripple and internal impedance. Thereafter, the calculating and analysis assembly thereafter determines the level of the source flow ripple level, which corresponds to source fluidborne noise characteristics of the pump, based upon the calculated source flow ripple.

摘要： Systems and methods for controlling a vehicle including a friction control device are provided. A method of controlling the vehicle includes operating at least one friction control device in a first of a plurality of friction modes, detecting a vehicular speed, changing operation of the at least one friction control device from the first friction mode to a second of the plurality of friction modes in response to the vehicular speed exceeding a first threshold speed value, and changing operation of the at least one friction control device from the second friction mode to the first friction mode in response to the vehicular speed falling below a second threshold speed value that is less than the first threshold speed value. The second friction mode is associated with a higher level of resistance than the first friction mode.

摘要： A bi-directional damper valve is provided for connecting to a hydraulic line, to regulate fluid flow therethrough. The damper valve includes a main valve body having a flow passage formed therethrough, and the flow passage widens at central portion of the valve body to form a central chamber, which has valve seats formed at opposite ends thereof. The main valve body also has two bypass channels formed therein, which branch off the central chamber near the valve seats, and which selectively communicate with the flow passage. The damper valve also includes two poppets, oriented facing in opposite directions in the central chamber. Each of the poppets has a hollow bore formed therethrough, to always allow fluid flow through the damper valve at a first (minimal) rate. The damper valve also includes a spring extending between the poppets, and normally biasing them against the valve seats.
