The invention discloses a driving energy consumption and comfort optimization control method, system and device and an electric vehicle, and the method comprises the steps: obtaining the driving parameters of the electric vehicle, entering a vehicle weight estimation state when a preset condition is satisfied, and exiting the vehicle weight estimation state after a calibration duration is reached; the actual torque feedback value of the motor in the vehicle weight estimation state is obtained, and the current vehicle weight is calculated by combining the whole vehicle parameters of the electric vehicle; setting a vehicle weight state standard according to the load parameters, and determining the current vehicle weight state of the electric vehicle; determining the current driving condition of the electric vehicle according to the real-time driving parameters of the electric vehicle and a preset driving condition standard; and according to different driving working conditions and accelerator pedal opening degrees under different vehicle weight states, different preset proportions of required torque value calibration are adjusted, and meanwhile energy recovery torque value calibration is adjusted. According to the technical scheme, energy consumption can be reduced, consistent driving expectation and feeling can be brought in different vehicle weight states, and comfort is improved.
