A control system for a vehicle includes a speed sensor that generates a vehicle speed signal. A sway detection sensor generates an oscillation signal. A brake control is coupled to a vehicle brake and is associated with a trailer brake. A controller is coupled to a stability control system and brakes one or more of the vehicle brake and the trailer brake and in response to the oscillation signal.

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.

A vehicle suspension system () includes a suspension (). A lateral acceleration sensor () generates a lateral acceleration signal. A roll rate sensor () generates a roll rate signal. A controller () detects an irregularity in the suspension in response to the lateral acceleration signal and the roll rate signal. A method of detecting suspension irregularities in a vehicle () includes the generating of a lateral acceleration signal and a roll rate signal. Roll angle is determined in response to the lateral acceleration signal and roll rate signal. A roll gradient, a roll acceleration coefficient, and a roll damping parameter are determined in response to at least the roll angle. The roll gradient, the roll acceleration coefficient, and the roll damping parameter are compared to associated nominal values. A suspension irregularity is indicated in response to the comparison.

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.
