1. A drive force system for facilitating a more efficient operation of a vehicle using pulsing and gliding of the vehicle, the drive force system comprising:

  • an engine configured to provide power to move the vehicle;

    a transmission operatively coupled to the engine;

    an accelerator sensor configured to detect an accelerator input; and

    a controller connected to the accelerator sensor and the engine,wherein the controller is configured to accept the accelerator input and control the engine to provide limited or no power to the transmission in a glide state when the accelerator input is within a first range of values and automatically control the engine to provide a substantially constant power to the transmission in a pulse state or a constant power state when the accelerator input is within a second range of values that is greater than the first range of values, andwherein the controller is configured to transition between the glide state and the pulse state or the constant power state based on the accelerator input for improving energy efficiency of the vehicle.
