Damping force control apparatus

Номер: US20120010780A1
Автор: Taisuke Hayashi, Yanqing Liu, Yuichi Mizuta
Принадлежит: Toyota Motor Corp

A control mode for a damping force characteristic is set to be a variable control when a product of the sum x b ′ of sprung member speeds and a sprung-member-unsprung-member-relative-speed x s ″ is positive. Accordingly, when the vibration in a middle/high frequency range is not being input to a suspension apparatus, an operation of a variable throttle mechanism is controlled so that a step number representing the damping force characteristic of a damper varies with a vibration state of a sprung member HA based on a Nonlinear H ∞ control theory. When the product of x b ′ and x s ′ is negative, the control mode is set to be an operation prohibiting control. When the vibration in the middle/high frequency range is input to the suspension apparatus, operation of the variable throttle mechanism is prohibited, and suppresses an increase in the operation frequency or in the operation amount of the variable throttle mechanism.

Methods and apparatus for sag adjustment

Номер: US20120080279A1

Принадлежит: Fox Factory Inc

A method and apparatus for adjusting the sag setting of a vehicle suspension are disclosed. An integrated damper/gas spring shock absorber includes a bleed port located at a position on a gas spring cylinder corresponding to a desired sag setting. The gas spring may be over pressurized to a pressure above the expected operating pressure of the gas spring. The vehicle may then be loaded with the normal operating load, partially compressing the shock absorber. Opening the bleed port allows gas to vent from the gas spring, further compressing the shock absorber until a piston in the gas spring closes the bleed port from the inner surface of the gas spring cylinder. A sleeve may be inserted over the gas spring cylinder, the sleeve including one or more sealing elements that seal the bleed port from the outer surface of the gas spring cylinder during normal operation.

Method and system for determining a reference yaw rate for a vehicle

Номер: US20120109458A1
Автор: David M. Sidlosky
Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

The method and system described herein may be used to determine a reference yaw rate (γ ref ) for a vehicle chassis control system, and may do so across a wide spectrum of vehicle operating conditions. These conditions may include, for example, when the vehicle is being driven: at low and high vehicle speeds, in forward and reverse directions, with front-, rear- and all-wheel steering systems, according to subtle and aggressive driving maneuvers, and on roads with flat or banked surfaces, to cite a few of the potential scenarios. According to an exemplary embodiment, the method and system take into account certain tire dynamics, such as the relaxation length (λ) of the tires, when estimating the reference yaw rate (γ ref ). Once an accurate reference yaw rate (γ ref ) is determined, the vehicle chassis control system may use this estimate to control one or more actuators that can influence the yaw rate of the vehicle. Some non-limiting examples of systems that may include such actuators are chassis systems, brake systems, steering systems, suspension systems, safety systems, stability control systems, traction control systems, torque control systems, or any other system that can affect the vehicle yaw rate. It is also possible for the method and system described herein to determine a reference lateral velocity (V yref ) for the vehicle as well.

Here, an active chassis device is used to make different adjustments, for example with respect to the toe-in angle and the camber angle, of a wheel or else with respect to wheel loads as a function of the drive load. As a result, the driving behaviour can be matched in each case in an optimum way to the drive mode, or conversely can be configured in such a way that changing the drive mode does not have a perceptible effect for the driver.

A low cost leaning vehicle stability and self-righting system that primarily uses gravity to return a leaning vehicle position to its original stable upright position. The system accomplishes this by increasing the leaning vehicle's Center of Gravity (CG) above the resting upright position—thus increasing the CG energy state—the more the vehicle leans. The system stores energy—a combination of additional and recovered energy normally lost when the vehicle leans—primarily in the form of gravitational potential energy to automatically return the vehicle from a leaning position to the upright stable position.

A control method for hybrid electromagnetic suspension. The method provides four modes for hybrid electromagnetic suspension: a comfort mode, a sport mode, a combined mode, and an energy feedback mode. A driver can switch between the four modes as desired. For the comfort, sport, and combined modes, hybrid control is adopted, and two sub-modes are provided: an active control mode and a semi-active control mode. A switching condition between the two sub-modes is determined by using a novel parameter Cand comparing the same against a maximum equivalent electromagnetic damping coefficient Cof a linear motor. The present invention solves the problem of achieving a balance between suspension comfort and tire traction, and meets the demands of different operating conditions and users by enabling manual mode switching. In addition, the hybrid control is employed to solve the problems of high energy consumption of active suspension and limited control performance of semi-active suspension, thus ensuring good kinematic performance of automobile suspension while reducing energy consumption. Furthermore, the energy feedback mode is designed to enable the suspension to perform energy recovery, meeting demands of energy conservation and emission reduction. 4.
