System and method for controlling coasting of hybrid vehicle equipped with automated manual transmission
First Claim
1. A method for controlling coasting of a hybrid vehicle equipped with an Automated Manual Transmission (AMT), comprising:
- varying, by a controller, an amount of regenerative braking based on a degree of manipulation of an accelerator pedal within a predetermined control range of a total degree of manipulation of the accelerator pedal from when the accelerator pedal is not being manipulated; and
decreasing, by the controller, the amount of regenerative braking as the degree of manipulation of the accelerator pedal increases.

Abstract
A technique for controlling coasting of a hybrid vehicle equipped with an Automated Manual Transmission (AMT) is disclosed herein. First, the amount of regenerative braking is varied based on the degree of manipulation of an accelerator pedal within the predetermined control range of a total degree of manipulation of the accelerator pedal from when the accelerator pedal is not being manipulated. The amount of regenerative braking decreases as the degree of manipulation of the accelerator pedal increases. The control range is used to perform control in such a way as to vary the amount of regenerative braking according to the amount of manipulation of the accelerator pedal. Further, the control range is set to within a range of initial 5 to 20% of the total degree of manipulation of the accelerator pedal.

5. A method for controlling coasting of a hybrid vehicle equipped with AMT, comprising:
determining whether a degree of manipulation of an accelerator pedal falls within a predetermined control range when a vehicle speed is 0; in response to determining that the degree of manipulation of the accelerator pedal falls within the control range, calculating a deceleration request conversion index corresponding to a current degree of manipulation of the accelerator pedal based on a conversion map including a deceleration request conversion index of the degree of manipulation of the accelerator pedal within the control range; calculating a converted-deceleration request torque using a percentage by multiplying a deceleration request torque determined according to a vehicle speed by the calculated deceleration request conversion index; and performing regenerative braking based on the calculated converted deceleration request torque. - View Dependent Claims (6, 7)
