The invention provides a vehicle control method, a vehicle controller and a vehicle system. The method comprises the following steps: acquiring a plurality of first parameters; performing various filtering processing on the plurality of first parameters to obtain a plurality of groups of second parameters; calculating the sum of a plurality of correlation coefficients corresponding to each group of second parameters to obtain a correlation coefficient sum; calculating the sum of a plurality of variances corresponding to each group of second parameters to obtain a variance sum; determining a filtering constant corresponding to a maximum value in the plurality of correlation coefficient sums and a minimum value in the plurality of variance sums as a target filtering constant; performing filtering processing on the plurality of first parameters by adopting a target filtering constant to obtain a plurality of target parameters, and calculating a target load capacity of the vehicle according to the target parameters; according to the target load capacity, working parameters of the vehicle are adjusted, and the working parameters at least comprise power and the working period of a thermal management system of the vehicle. The method solves the problem that the accurate control of the vehicle cannot be realized due to the inaccurate estimation of the load capacity of the vehicle.
