The invention discloses a straddle type monorail vehicle transverse stability control method based on multi-objective optimization. The method comprises the steps that target parameters influencing the transverse stability of a vehicle are determined; constructing a vehicle transverse stability optimization control model by taking a yaw angular acceleration root mean square, a transverse acceleration root mean square and an overturning coefficient as optimization targets and taking target parameters as design parameters; all parameter values in the vehicle transverse stability optimization control model are adjusted, so that the vehicle transverse stability optimization control model obtains the minimum value, design parameters set when the vehicle transverse stability optimization control model obtains the minimum value serve as optimization control parameters, and the optimization control parameters are used for controlling the vehicle transverse stability. According to the method, different optimization targets can be measured on the same dimension, and the transverse stability of operation of the vehicle under variable working conditions is improved.
