The invention relates to the technical field of automobile cruise control, and particularly discloses a heavy truck constant speed cruise torque calculation method based on multi-parameter control, when a driver operates a truck to enter a constant speed cruise state, a cruise torque calculation control unit calculates cruise torque in a multi-parameter control mode, so that a target vehicle speed is quickly reached, and the cruise torque is calculated by a cruise torque calculation control unit in a multi-parameter control mode. The multiple parameters comprise a vehicle speed PI adjusting torque value, an acceleration PI adjusting torque value, a compensation torque value generated by a vehicle weight parameter, a basic torque value and a torque value at the last moment; the cruise torque calculation control unit calculates a torque value required by the current target vehicle speed according to the current vehicle condition information, so that the cruise target vehicle speed can be quickly reached, and the stability of the vehicle is kept; the control method can be autonomously suitable for cruise speed control under various vehicle conditions, PI parameters under special working conditions do not need to be manually calibrated any more, and intelligent and precise control over the vehicle is improved.
