The invention relates to a rear-wheel tracking and steering control method based on rectangular coordinates and polar coordinates and an automobile. The rear-wheel tracking and steering control method is characterized by including setting up a rectangular coordinate or polar coordinate system by taking a rear wheel as a coordinate origin when front wheels start steering, setting step length by taking the unit advancing distance of the front wheels, and continuously recording front-wheel track during running; determining the current time moment position point and the next position point of the rear wheels on the front-wheel track according to the distance and the step length between the front wheels and the rear wheels, and calculating rear-wheel steering angle of the current time moment; enabling the step length to be small enough when selecting the step length under the condition that the step length is the unit advancing distance of the front wheels, so that the error between the rear-wheel displacement and the front-wheel displacement can be as small as possible within the time corresponding to the step length. The rear-wheel track and the front-wheel track can be highly fitted. By the rear-wheel tracking and steering control method, stability and safety during turning of the automobile can be greatly improved, and cure passing ability of the automobile can be greatly improved.
