The invention provides a driving behavior evaluation method and system in automatic driving, and the method comprises the steps: obtaining vehicle state information and current road information, and searching a slope top position and a slope bottom position in a road; in the gear sliding state, according to the vehicle dynamic state equation, the vehicle speed behind the slope crest is subjected to recursion, and the optimally-controlled slope crest target vehicle speed is determined; calculating a slope crest kinetic energy difference according to the actual vehicle speed of the vehicle at the slope crest and the slope crest target vehicle speed; the total kinetic energy loss in the gear sliding state is counted; calculating an expected average speed and an actual average speed of vehicles on the remaining road sections; calculating the fuel consumption increment of the remaining road sections according to the expected average speed and the actual average speed of the vehicle; and calculating a whole-course fuel consumption saving net value under the optimal control condition of the difference between the fuel consumption increment and the total kinetic energy loss, and evaluating the current automatic driving behavior based on the fuel consumption saving net value. According to the scheme, the calculation process is simple, automatic driving behavior evaluation can be achieved, and reference can be provided for ramp driving behavior optimization.
