摘要： A method of controlling a vehicle may include determining a proximity to a stuck condition based on measured vehicle motion parameters and a wheel speed measured by a wheel speed sensor associated with one or more wheels of the vehicle. The method may further include generating a notification to a driver of the vehicle in response to the proximity to the stuck condition indicating that the vehicle is either in a stuck condition or a nearly stuck condition, and responsive to driver selection of an unstuck mode, executing an unstuck algorithm to automatically control operation of the vehicle to achieve a free condition.

摘要： An apparatus and method for controlling damping force characteristics of respective vehicular shock absorbers in which vehicular vertical behavior(s) at the position(s) of the vehicular body which are forward by a predetermined distance from a tread of rear left and right road wheels are determined, the positions including front left and right road wheel sides, and corresponding vertical behavior signals are derived. Control signals for front left and right and rear left and right road wheel side shock absorbers are formed on the basis of respective processed signals having frequency-dependent characteristics formed from the vehicular behavior signal(s). The damping force characteristics of front left and right road wheel side shock absorbers are controlled on the basis of the control signals formed on the basis of the processed signal based on the front left and right road wheel vehicular behavior signals. Those of rear left and right road wheel side shock absorbers are controlled on the basis of the control signals formed on the basis of the processed signals based on the front position vehicular vertical behavior signal at the position forward from the tread between the rear left and right road wheels. The phases of the control signals V are generally matched with vehicular behavior velocity signals which would actually be generated at rear road wheel arranged positions of the vehicle.

摘要： A magnetostrictive stress and torque sensor using the component of the output signal in-phase with the drive voltage to monitor stress or torque. In some embodiments, it may use the quadrature or out-of-phase component, or some combination of the in-phase and out-of-phase components. Such phase component monitoring has several advantages over magnitude detection, including a response which is a more linear function of torque, and which is not subject to overmodulation problems.

摘要： A vehicle has a real time suspension control which requires, as inputs, a set of absolute body modal velocity signals. Accurate estimates of these signals are derived from relative position sensors at the body suspension points by converting the relative vertical position signals from these sensors to relative body modal (e.g. heave, pitch and roll) velocity signals and passing each of these signals through a second order low pass filter including an additional phase inversion for compensation of the 180 degree filter phase lag. Thus, the necessity of absolute body accelerometers is eliminated, for a significant cost reduction. In a vehicle having significant front to rear flexing or flexing within the front or rear suspension that can affect the accuracy of the estimated absolute body roll velocity, the normal roll velocity transformation equation is modified to include only the front or the rear pair of relative velocity signals.

摘要： In a hydraulic active suspension system, a plurality of actuators having working fluid chambers are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height as the results of the supply and the discharge of working fluid to and from its working fluid chamber, respectively. Supplying and discharging devices supply working fluid to and discharge from the working fluid chamber. Vehicle height sensors detect the vehicle heights at the locations corresponding to the vehicle wheels. A control device is further provided. The control device controls the supplying and discharging devices so that the pressure within the working fluid chamber in each actuator may be a value corresponding to the sum of a basic pressure determined according to the running conditions of the vehicle and a compensating pressure determined based upon the integral value of the difference between a standard vehicle height and an actual vehicle height. When the integral value of the difference is larger in magnitude than a predeterminate value, it is reduced in magnitude by the control device so as to prevent the control with the compensating pressure from overriding the control with the basic pressure.

摘要： The active damping system includes an electrical current conductive coil spatially fixed with respect to one of the sprung mass and unsprung mass of a vehicle and a magnetic element spatially fixed with respect to the other of the sprung mass and the unsprung mass. Relative motion is imparted between the coil and the magnetic element in response to relative motion between the sprung mass and the unsprung mass. This relative motion is in response to random input vibrations from a road surface. The magnetic element develops a magnetic flux intersecting the coil to develop and induced current through the coil wherein the induced current develops an electromotive force on the magnetic element opposing the relative motion to act as the active damping element. The active damping system also includes means for developing a control current through the coil to oppose motion of the sprung mass relative to the road surface occurring below a selected frequency.

摘要： A suspension control system for automotive vehicles automatically adjusts the damping strength of variable shock absorbers or other dampers in accordance with road surface conditions as recognized by frequency analysis of a vehicle height or vibration sensor signal. The sensor signal reflects vertical displacement of the vehicle body from the road surface and includes high-frequency components due solely to displacement of the wheels of unsprung mass relative to the road surface and low-frequency components due to displacement of the vehicle body or sprung mass. The sensor signal is filtered into these separate frequency bands, the amplitude of each of which is compared to a corresponding reference level. The results of comparison give an indication of the degree and scale of irregularities in the road surface; specifically, a high-amplitude low-frequency component indicates larger-scale bumps and dips capable of bouncing the vehicle whereas a strong high-frequency component reflects a rough-textured road surface, such as a gravel. The comparison information is sent to a suspension system controller which causes actuation of the shock abosrbers to a stiffer mode of operation when the low-frequency sensor signal components are relatively strong.
