The invention discloses an intelligent networked passenger car torque gradient self-adaptive adjustment control method and system, and relates to the technical field of intelligent networked vehicles, and the method comprises the steps: obtaining state data in a vehicle driving process in real time; according to the acquired data, determining a motor driving torque required at the current moment, and further determining a motor expected torque at the current moment; the driving state of the vehicle at the current moment is determined, and the lifting torque state and the expected torque gradient at the current moment are determined in combination with the expected torque of the motor; based on the expected torque gradient at the current moment and the actual torque gradient at the previous moment, torque gradient self-adaptive adjustment based on set scale progressive increase or progressive decrease is carried out, and the actual torque gradient at the current moment is obtained; and adding and subtracting the actual torque of the motor based on the actual torque gradient at the current moment, calculating to obtain a final target request torque, and sending the final target request torque to a motor controller for torque smooth control. Smooth control over the torque can be achieved, the driving comfort is improved, and the service life of the vehicle is prolonged.
