The invention discloses a mass center position measurement and adjustment method for an emergency rescue vehicle. Implementation of the method relies on a measurement system which comprises a parameter measurement unit, a data processing unit and an execution mechanism unit; the parameter measurement unit is provided with an air pressure sensor for measuring the pressure of wheels; the data processing unit comprises a single chip microcomputer, an external communication interface, an A/D converter and a D/A converter; a sensor in the parameter measurement unit is connected with the data processing unit; the execution mechanism unit comprises a cross flat plate fixed to a chassis of the vehicle, the cross flat plate is provided with four balancing weights controlled by two servo motors, anddistribution of the four balancing weights meets the condition that the whole mass center of the balancing weights of the flat plate coincides with the initial mass center of a vehicle body. The method comprises the steps that the mass of the whole vehicle is determined, the transverse and longitudinal positions of the mass center of the vehicle body are determined, and the position of the mass center of the vehicle body is adjusted. According to the mass center position measurement and adjustment method, the functions of measuring and adjusting the position of the mass center of the vehicleduring driving are achieved, and the stability and safety of cross-country driving of the emergency rescue vehicle are improved.
