The invention discloses an elevator car driving control system, and belongs to the technical field of elevators. The driving control system comprises a driving motor rotating speed detector used for detecting the rotating speed of a driving motor of the elevator equipment, and a driving motor current detector used for detecting the current of the driving motor. The driving motor current controller is used for generating expected torque of the driving motor according to a difference value between a current instruction value and a current detection value of the driving motor; the driving motor speed controller is used for generating a current instruction value of the driving motor according to a difference value between a speed instruction value and a speed detection value of the driving motor; and the driving motor speed instruction generation unit is used for generating a speed instruction value of the driving motor according to an externally input lift car speed instruction, a rotation detection value of the driving motor and a speed detection value of the elevator lift car. The technical scheme has the beneficial effects that the deformation quantity of the flexible connector is included in the driving control cycle, and the driving control performance is improved.
