1. A control system for a vehicle comprising:
- a GPS system generating a vehicle position signal for a vehicle relative to a surface;
a plurality of driver inputs;
a plurality of vehicle sensors each providing a vehicle input; and
a controller coupled to the GPS system, the plurality of driver inputs and the plurality of vehicle inputs, said controller determining a predicted path in response to the plurality of driver inputs and the vehicle inputs, and determining a desired path in response to the GPS system, said controller performing a comparison of the predicted path and the desired path, said controller generating a control signal in response to the comparison,wherein said controller performs the comparison using colinearity of a confidence level, or a linear regression model with said threshold corresponding to an estimated error.

Abstract
A control system (12) for an automotive vehicle (10) includes a GPS system (16) that generates a vehicle position for a vehicle relative to a surface, a plurality of driver inputs (40), and a plurality of vehicle inputs (50). A controller (14) is coupled to the GPS system (16), the driver inputs (40) and the vehicle inputs (50). The controller determines a predicted path in response to the plurality of driver inputs and the vehicle inputs and a desired path in response to the GPS system (16). The controller performs a comparison of the predicted path and the desired path and generates a control signal in response to the comparison.
