A technique is disclosed for providing a charge pump circuit for phase locked loop to reduce mismatch of updown currents and feed-through of updown currents to voltage output. The vehicle has a braking system designed for outside force actuation, a control device for controlling the vehicle brakes, and a brake light switch located in the vicinity of a brake pedal, which is connected with a control device for controlling at least one brake light. The width of the platform is 4 to 7% of the diameter of the shaft. The method then determines a representative form for the input shape based on a similarity measure between the input shape and the classified template shape.
