The invention relates to the technical field of control of polling robots, and discloses a cornering control method for a vehicle type polling robot. The cornering control method comprises the steps as follows: 1, the deviation value of the vehicle body of the vehicle type polling robot on a runway at a current position is acquired; 2, an angle adjustment unit computes an output command accordingto the deviation value, and generates a PWM driving signal for controlling a steering wheel according to the output command; and 3, a speed adjustment unit computes a speed command according to the output command of the angle adjustment unit, and generates the PWM driving signal for controlling a driving wheel according to the speed command. According to the cornering control method provided by the invention, the adaptive control of the angle adjustment unit and the coordinated cornering control between the angle adjustment unit and the speed adjustment unit are achieved without adding the hardware equipment, the situation that the vehicle type polling robot can corner stably under the different polling path bend curvatures is ensured, and the cornering sideslip phenomenon of the vehicle type polling robot is suppressed.
