Driving force control system for hybrid vehicle

A driving force control system for a hybrid vehicle having a prime mover including an engine and a motor that generates a system torque to achieve a required driving force to propel the hybrid vehicle, comprising:

• a controller that controls torques of the engine and the motor,
• wherein the controller comprises
• a first acceleration controller that is configured to increase the torque of the engine to a predetermined torque with an increase in the system torque,
• a second acceleration controller that is configured to restrict the torque of the engine which has been increased to the predetermined torque to the predetermined torque or less within a predetermined period of time, and
• a third acceleration controller that is configured to increase the torque of the engine which has been restricted by the second acceleration controller to achieve the system torque.
