The invention provides an analytic method of a driver driving intention. The method comprises the following steps: the sum of the maximum torque of an engine at an output shaft end and the maximum driving torque of a motor at the output shaft end serves as a first demand torque when the openness of an acceleration pedal is 100%; the maximum value among the maximum braking torque at the output shaft end, the maximum brake torque limiting value at the output shaft end and the maximum braking torque limiting value for preventing the reversing is taken as a second demand torque when the openness of the acceleration pedal is 0; and an actual demand torque is obtained by a linear interpolation method according to the first demand torque and the second demand torque when the openness of the acceleration pedal is within 0-100%. The analytic method of the driver driving intention can enable the obtained actual demand torque to become more precise, can improve the brake recovery efficiency, and can improve the fuel economy.
