A method for brake pressure apply in a hydraulic brake system includes commanding a cage clearance reduction phase and commanding a wheel control phase subsequent to the cage clearance reduction phase. Accordingly, the cage clearance is reduced prior to entering the wheel control phase. A method for cage clearance reduction in a hydraulic brake system for roll stability control is also provided.

Brake pressure apply

A roll control system () for an automotive vehicle () is used to actively detect if one of the plurality of the driven wheels () is lifted. The system generates a pressure request to determine if the wheel has lifted. By comparing the change in wheel speed of a driven wheel to a change in wheel speed threshold the wheel lift status can be determined. The wheel speed change threshold may be dependent upon various vehicle operating conditions such as powertrain torque, braking torque and/or longitudinal force on the vehicle.

Active driven wheel lift identification for an automotive vehicle

A control system () and method for an automotive vehicle () includes a pitch rate sensor () generating a pitch rate signal, a longitudinal acceleration sensor () generating a longitudinal acceleration signal, and a yaw rate sensor () generating a yaw rate signal. A safety system () and the sensors are coupled to a controller. From the sensors, the controller () determines an added mass and a position of the added mass, a pitch gradient and/or a pitch acceleration coefficient that takes into account the added mass and position. The controller controls a vehicle system in response to the added mass and the position of the added mass, the pitch gradient and/or pitch acceleration coefficient variables.

System for dynamically determining vehicle rear/trunk loading for use in a vehicle control system

A control system () and method for an automotive vehicle () includes a roll rate sensor () for generating a roll rate signal, a lateral acceleration sensor () for generating a lateral acceleration signal, a longitudinal acceleration sensor () for generating a longitudinal acceleration signal, and a yaw rate sensor () for generating a yaw rate signal. A safety device or system () and the sensors are coupled to a controller. The controller () determines an added mass and the height of the added mass on the vehicle, or a roll gradient, a roll acceleration coefficient, and/or a roll rate parameter that take into account the added mass and height from the roll rate, the lateral acceleration, the longitudinal acceleration, and the yaw rate of the vehicle, and controls the safety system in response thereto.

System and method for dynamically determining vehicle loading and vertical loading distance for use in a vehicle dynamic control system

A control system for a vehicle () is described for use in conjunction with the safety system () of the vehicle (). A tire sensor or plurality of tire sensors generates tire force signals. The tire force signals may include lateral tire forces, longitudinal (or torque) tire forces, and normal tire forces. Based upon the tire force signals, a safety system () may be activated. The tire force sensors may be used to monitor various conditions including but not limited to sensing a roll condition, wheel lift detection, a trip event, oversteering and understeering conditions, pitch angle, bank angle, roll angle, and the position of the center of gravity of the vehicle.
