The invention discloses a heterogeneous traffic flow energy consumption optimization method and system based on adaptive cruise control. The method comprises the following steps: determining an expected following distance according to a variable time headway; according to the expected car-following distance, constructing a heterogeneous traffic flow car-following model on the basis of considering the headstock distances in different car-following modes and the permeability of different types of vehicles; based on the heterogeneous traffic flow car-following model and the expected car-following distance, constructing a discrete adaptive cruise controller for enabling the target vehicle to follow the front vehicle to run at the expected car-following distance; and according to the discrete adaptive cruise controller and the heterogeneous traffic flow car-following model, taking the minimum total energy consumption of the heterogeneous traffic system and the minimum loss of safety, comfort and passing efficiency as objective functions to obtain an energy consumption optimization result of the heterogeneous traffic flow car-following system. The problem that in the intelligent network connection heterogeneous traffic environment, the vehicle accelerates and decelerates too much in the random following process is solved, and the energy consumption of a traffic flow system is reduced.
