The invention discloses a vehicle speed and steering information obtaining method and system, and an intelligent terminal. The method comprises the steps of acquiring an original vehicle speed signal on a vehicle speed sensor in a to-be-detected vehicle in a signal coupling mode; performing signal processing on the obtained original vehicle speed signal to obtain a square wave signal; multiplying the square wave signal by a pre-stored coefficient to obtain the current speed of the to-be-detected vehicle, wherein the coefficient is a speed calibration coefficient related to the vehicle type; and the current vehicle speed includes a left wheel vehicle speed obtained by a vehicle speed sensor on a left wheel and a right wheel vehicle speed obtained by a vehicle speed sensor on a right wheel; obtaining a current left wheel turning radius and a current right wheel turning radius based on the left wheel vehicle speed and the right wheel vehicle speed; and according to the relation between the current left wheel turning radius and the current right wheel turning radius, acquiring current steering information. The technical problems that in the prior art, the vehicle speed and steering information of a vehicle auxiliary driving system are inconvenient to obtain, and normal vehicle communication is affected are solved.
