A method and system for controlling vehicle stability may comprise determining whether a vehicle is oversteering or understeering and, if the vehicle is oversteering or understeering, determining an amount by which to reduce a speed of the vehicle to correct for understeering or oversteering and applying brake pressure to at least the rear brakes of the vehicle to reduce vehicle speed. The method and system also may comprise determining an engine torque reduction amount based on vehicle oversteer or understeer conditions, reducing engine torque by the determined amount or to zero if the determined amount of engine torque reduction is greater than an actual engine torque, and applying braking to at least the rear brakes of the vehicle if the determined amount of engine torque reduction is greater than the actual engine torque.

Vehicle stability control system and method

A vehicle control system includes one or more driver intent detection devices to detect at least a curve-negotiating intention of a driver. The system also includes one or more curvature detection devices, to detect or otherwise determine a road curvature. The system further includes one or more overspeed control devices, to, based at least in part on data received from the one or more curvature detection devices and data received from the one or more driver intent detection devices, cause braking to one or more vehicle tires and/or reducing engine torque to keep a vehicle accurately negotiating the curved road for the current driving condition.

Curve-related accident mitigation

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.

System and method for controlling a safety system of a vehicle in response to conditions sensed by tire sensors related applications

A control system () and method for an automotive vehicle () includes a lateral acceleration sensor () for generating a lateral acceleration signal, a yaw rate sensor () for generating a yaw rate signal, and a safety system. The safety system () and the sensors are coupled to a controller (). The controller () determines a front lateral tire force and a rear lateral tire force from the vehicle yaw rate signal and the vehicle lateral acceleration signal; determines a calculated lateral velocity from the front lateral tire force, the rear lateral tire force, and a bank angle; determines a calculated yaw rate from the front lateral tire force and the rear lateral tire force; and controls the safety system in response to the calculated lateral velocity and the calculated yaw rate.
