Patent ID: 7813890

Claim:
A method, comprising: determining a wheel speed, a transmission output speed and a vehicle state reflective of a plurality of vehicle dynamic parameters of a vehicle; and determining that the vehicle is stopped if, after a predetermined period of time, the wheel speed and transmission output speed each remain substantially equal to zero, and the vehicle state remains stable; wherein the plurality of vehicle dynamic parameters includes at least one of a rate of change of a yaw rate, a lateral acceleration, and a longitudinal acceleration parameter; wherein determining that the vehicle is stopped further includes processing the plurality of vehicle dynamic parameters to determine if the vehicle state remains stable; and wherein processing the plurality of vehicle dynamic parameters further includes processing the plurality of vehicle dynamic parameters according to X = ∑ 1 N ⁢ ⁢ ( x n , x n + A , x n + B , x n + C , x n + D ) / S , where X is a rolling average, N is a predetermined number of time intervals, x n is a first sample of the first parameter, x n+A is a second sample of the first parameter, x n+B is a third sample of the first parameter, x n+C is a fourth sample of the first parameter, x n+D is a fifth sample of the first parameter, and S is a total number of samples obtained.
