The invention discloses an unmanned electric vehicle control method and system combined with road condition information. The control method comprises the following steps that it is judged that a vehicle is in one of the four running modes of parking, starting, running and braking; environment information is collected and processed; the environment information is obtained through a wind speed sensor and a battery definite specific friction coefficient calculation method; calculating the total running resistance of the automobile according to the environment information; acquiring the state of charge of the battery; performing motor control; according to the driving mode, the driving resistance and the state of charge of the battery, control parameters of motor control are changed to achieve adjustment of whole vehicle control; the motor control comprises rotating speed control and torque control. According to the unmanned electric vehicle control method and system combined with the road condition information, the external environment information can be effectively sensed through the wind speed sensor and a battery definite specific friction coefficient calculation method, motor control is conducted according to the environment information, and the unmanned driving stability, controllability and functionality can be greatly improved.
