The invention relates to a vehicle mass estimation method and a chassis central integrated control system. The vehicle mass estimation method comprises the following steps: determining the effectiveness of a vehicle acceleration mass estimation method, a suspension height mass estimation method and a tire pressure estimation method according to acquired road information, gradient information, weather information and vehicle information; determining weight coefficients of the three estimation methods according to the effectiveness of the three estimation methods; and carrying out weighted summation on the vehicle masses estimated by the three estimation methods and the corresponding weight coefficients to obtain a vehicle mass estimation value. The invention further provides a chassis central integrated control system. The chassis central integrated control system comprises a chassis central controller, and a vehicle body attitude sensor, a tire pressure sensor, a suspension system, a steering system, a braking system, a power system and an ADAS system which are connected with the chassis central controller. The problem that an existing vehicle mass estimation method is easily influenced by driving working conditions and vehicle load changes, and consequently estimation precision is influenced is solved.
