A method and system may determine, in a vehicle, a desired path around an object based on a location of the object relative to the vehicle, relative speed, road parameters and one or more vehicle parameters. The method and system may calculate one or more vehicle control parameter values which minimize a predicted deviation from the desired vehicle path. The method and system may determine whether the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints. If the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints, the one or more vehicle control parameter values may be reduced to one or more vehicle control parameter values not causing the vehicle to exceed the one or more vehicle stability constraints. The method and system may output the one or more vehicle control parameter values to a vehicle automated control device. |

1. A method for applying emergency maneuvers to a vehicle to avoid collision, the method comprising:
detecting, by a sensor, a threat of collision with an object; activating a collision avoidance control system; detecting, by the collision avoidance control system, whether a driver of the vehicle has initiated an action; responsively to detecting that the driver has initiated an action, performing, by the collision avoidance control system, an assisted emergency maneuver, wherein the assisted emergency maneuver assists the driver in avoiding collision with the object; responsively to detecting that the driver has not initiated an action, performing, by the collision avoidance control system, an automatic emergency maneuver, wherein the automatic emergency maneuver performs actions to avoid collision with the object; determining, in the vehicle, a desired path around the object based on a location of the object relative to the vehicle, a relative speed, a road parameter, and a vehicle control parameter; calculating a vehicle control parameter value which minimizes a predicted deviation from a desired vehicle path; determining whether the vehicle control parameter value would cause the vehicle to exceed a vehicle stability constraint; altering, if the vehicle control parameter value would cause the vehicle to exceed the vehicle stability constraint, the vehicle control parameter value to an alternate vehicle control parameter value, wherein the alternate vehicle control parameter value does not cause the vehicle to exceed the vehicle stability constraint; and outputting the alternate vehicle control parameter value to a vehicle automated control device. |
