Drive force control for vehicle
First Claim
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.

Abstract
Systems, methods and controllers for facilitating or providing a more efficient operation of a vehicle are disclosed. An accelerator input is detected from an accelerator sensor and it is determined whether the accelerator input is within a first range of values or within a second range of values. If it is determined that the accelerator input is within the first range of values, an engine is controlled to provide limited or no power to a transmission. If it is determined that the accelerator input is within the second range of values, the engine is controlled to provide a substantially constant power to the transmission.

10. A method of providing a more efficient operation of a vehicle using pulsing and gliding of the vehicle, the method comprising:
-
detecting an accelerator input from an accelerator sensor; determining whether the accelerator input is within a first range of values or within a second range of values that is greater than the first range of values; controlling an engine to provide limited or no power to a transmission in a glide state when it is determined that the accelerator input is within the first range of values and automatically controlling the engine to provide a substantially constant power to the transmission in a pulse state or a constant power state when it is determined that the accelerator input is within the second range of values; and transitioning 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A controller for providing a more efficient operation of a vehicle using pulsing and gliding of the vehicle, the controller comprising:
-
a computer-readable memory configured to store computer-executable process steps; and a processor configured to execute the computer-executable process steps stored in the memory, wherein the process steps include computer-executable process steps to; accept an accelerator input from an accelerator sensor; determine whether the accelerator input is within a first range of values or within a second range of values that is greater than the first range of values; and control an engine to provide limited or no power to a transmission in a glide state when it is determined that the accelerator input is within the 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 it is determined that the accelerator input is within the second range of values wherein 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. - View Dependent Claims (20)
