Damping force control apparatus

Номер: US20120010780A1
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.

Improved methods of controlling the stability of a vehicle are provided via the cooperative operation of vehicle stability control systems such as an Active Yaw Control system, Antilock Braking System, and Traction Control System. These methods use recognition of road surface information including the road friction coefficient (mu), wheel slippage, and yaw deviations. The methods then modify the settings of the active damping system and/or the distribution of drive torque, as necessary, to increase/reduce damping in the suspension and shift torque application at the wheels, thus preventing a significant shift of load in the vehicle and/or improving vehicle drivability and comfort. The adjustments of the active damping system or torque distribution temporarily override any characteristics that were pre-selected by the driver.

When a preview sensor acquires undulation information regarding a convex portion of a road surface, an electric actuator expands during a predetermined period of time between that point and a point immediately before the wheel rides on the convex portion, whereby ascending velocity of a sprung member increase. Therefore, when the wheel rides on the convex portion, the sprung member reaches estimated unsprung ascending velocity as a result of the expansion of the electric actuator up to that point. Accordingly, in the case where the wheel rides on the convex portion and an unsprung member is pushed up, a change in the sprung vertical velocity caused by application of the pushing up force to the sprung member is reduced because the sprung member ascends at the estimated unsprung ascending velocity. Therefore, riding quality is improved. 1.
