PURPOSE: A method for correcting turning speed sensor offset of a car is provided to realize the ESC control more accurately than the natural control flow without area which flicks between applied models. CONSTITUTION: A method for correcting turning speed sensor offset of a car is an order offset correction in successively correction method of offset value considering the turning speed. And uses an offset correction algorithm based on model applying the car dynamics equation which use the sped or steering angle as an input element. After calculating the correction value of turning speed senor offset, weight value is given to output element p,q,r at the same which divides the speed and steering angle into specific area. And applies the integration fuzzy logic correction algorithm which calculates the correction value of the precalculated turning speed sensor offset with a average correction valueΨ. Therefore, the optimum turning speed sensor offset correction algorithm which continues the floe without flicking over the boundary is realized. |
