Adaptive regenerative braking method and system

1. A braking method, comprising:

when an accelerator pedal and a brake pedal of an electrified vehicle are not depressed, permitting a first amount of regenerative braking in the electrified vehicle if an upcoming deceleration is detected; and

when the accelerator pedal and the brake pedal of the vehicle are not depressed, permitting a second amount of regenerative braking if the upcoming deceleration is not detected, the second amount less than the first amount, wherein the second amount is no regenerative braking.

2. The braking method of claim 1 , further comprising monitoring to detect the upcoming deceleration, wherein the monitoring is based at least in part on information provided by an object detection system.

3. The braking method of claim 2 , wherein the monitoring is based at least in part on the object detection system providing an indication of an object in a predicted path of the electrified vehicle.

4. The braking method of claim 2 , wherein the monitoring is based at least in part on the object detection system providing an indication of a traffic signal signifying a required deceleration of the electrified vehicle, a stop sign, or some combination of these.

5. An electrified vehicle assembly, comprising:

a monitoring assembly; and

a controller that controls regenerative braking by permitting a first amount of regenerative braking when the accelerator pedal and the brake pedal are both not depressed or a second amount of regenerative braking less than the first amount when the accelerator pedal and the brake pedal are both not depressed, the controller permitting the first amount of regenerative braking when the monitoring assembly detects an upcoming deceleration, the controller permitting the second amount of regenerative braking when the monitoring assembly does not detect the upcoming deceleration, wherein the second amount of regenerative braking is no regenerative braking.

6. The electrified vehicle of claim 5 , wherein the controller is configured to vary the first amount of regenerative braking, the second amount of regenerative braking, or both.

7. A braking method, comprising:

moving a pedal of a vehicle from a first pedal position to a second pedal position;

if an upcoming deceleration is detected, permitting a first amount of regenerative braking in the electrified vehicle when the pedal is in the second pedal position; and

if the upcoming deceleration is not detected, permitting a second amount of regenerative braking when the pedal is in the second pedal position, the second amount of regenerative braking less than the first amount of regenerative braking, wherein the second amount of regenerative braking is no regenerative braking.

8. The braking method of claim 7 , wherein the pedal is an accelerator pedal of the vehicle, wherein the accelerator pedal in the first pedal position is depressed more than the accelerator pedal in the second pedal position.

9. The braking method of claim 7 , wherein the pedal is a brake pedal, wherein the brake pedal is not depressed when in the first pedal position and depressed in the second pedal position.

10. The braking method of claim 1 , wherein the first and second amounts of regenerative braking are amounts of regenerative braking torque.
