Claim 9:
10. A method for controlling a powertrain of an autonomous vehicle, the method comprising:
a step of determining whether the vehicle satisfies a pulse and glide (P&G) driving condition during autonomous driving;
a step of performing pulse driving, when the vehicle satisfies the P&G driving condition;
a step of performing coasting with a transmission in neutral, when the vehicle satisfies a condition for ending the pulse driving; and
a step of returning to the step of performing the pulse driving, when the vehicle satisfies a condition for ending the coasting,
wherein the step of performing the coasting includes
a step of engaging the clutch when vehicle speed falls within a predetermined range from minimum speed in a P&G driving speed range during the coasting, and
a step of requesting engine torque control to the engine controller when the vehicle speed reaches the minimum speed.
