The invention discloses the system and method for operation for improving motor vehicle driven by mixed power.In one example, it is provided that a kind of method of conversion between power train braking and wheel drag.A kind of method of car braking includes providing power train braking moment to vehicle, and friction braking torque is not put on vehicle；And reduce power train braking moment in response to the state of charge of energy storing device and increase the friction braking torque of described vehicle simultaneously, the amount that described friction braking torque increases is identical with the amount of described power train braking moment reduction.The method can improve vehicle drive performance and fuel economy. |
