The invention discloses an online synchronous identification method for the heavy truck air resistance composite coefficient and mass. An online identification model under the drive and neutral gear sliding work condition is established through a differential driving equation, and combined online identification of the air resistance composite coefficient and the whole truck mass is achieved through a recursion two-parameter least squares algorithm. The influence of the rolling resistance calculation error on the identification precision can be eliminated by selecting the differential driving equation. Synchronous online two-parameter identification has the characteristic of self-adaptation changeable air resistance, and the obtained mass identification result is not affected by the air resistance coefficient or the truck windward area error. The stable and reliable air resistance composite coefficient and truck mass can be obtained under different carrying modes and different masses and under wind speed changes and other various complex work condition environments.
