CONTROL METHOD FOR COASTING OF ECO-FRIENDLY VEHICLE
First Claim
1. A coasting control method of an eco-friendly vehicle, the method comprising steps of:
- acquiring, by a controller of the vehicle, deceleration event information and road gradient information in front of a vehicle during driving;
determining, by the controller, target vehicle speed in a deceleration event in consideration of road gradient based on the deceleration event information and the road gradient information;
determining, by the controller, expected vehicle speed while the vehicle is decelerated in a coasting state, based on current vehicle speed;
determining, by the controller, a start location for starting coasting based on target vehicle speed in consideration of current vehicle speed of the vehicle and the road gradient and expected vehicle speed at a target location as a deceleration event location;
operating, by the controller, an information provider for coasting guidance and coasting induction to a driver at a start location; and
controlling, by the controller, a creep torque of a driving motor during coasting of the vehicle in a brake pedal and accelerator pedal off state.

Abstract
A coasting control method of an eco-friendly vehicle includes steps of acquiring deceleration event information and road gradient information in front of a vehicle during driving, by a controller in the vehicle, determining target vehicle speed in a deceleration event in consideration of road gradient based on the deceleration event information and the road gradient information, by the controller, determining expected vehicle speed while the vehicle is decelerated in a coasting state, based on current vehicle speed, by the controller, determining a start location for starting coasting based on target vehicle speed in consideration of current vehicle speed of the vehicle and the road gradient and expected vehicle speed at a target location as a deceleration event location, by the controller, and operating an information provider for coasting guidance and coasting induction to a driver at a start location, by the controller.
