Method for controlling coasting drive of environmentally friendly vehicle
First Claim
1. A method for controlling a coasting drive of an environmentally friendly vehicle, the method comprising:
- calculating, by a control unit, a coasting velocity of the environmentally friendly vehicle at a deceleration event point based on a target coasting distance up to the deceleration event point and a gradient at the deceleration event point;
calculating, by the control unit, a control target velocity of the environmentally friendly vehicle based on a target velocity of the environmentally friendly vehicle at the deceleration event point and the calculated coasting velocity; and
determining, by the control unit, control torque to adjust a velocity of the environmentally friendly vehicle to the target velocity to be output to a powertrain of the environmentally friendly vehicle based on the calculated control target velocity.

Abstract
A method for controlling a coasting drive of an environmentally friendly vehicle includes: calculating a coasting velocity of the environmentally friendly vehicle at a deceleration event point based on a target coasting distance up to the deceleration event point and a gradient at the deceleration event point; calculating a control target velocity of the environmentally friendly vehicle based on a target velocity of the environmentally friendly vehicle at the deceleration event point and the calculated coasting velocity; and determining control torque to adjust a velocity of the environmentally friendly vehicle to the target velocity to be output to a powertrain of the environmentally friendly vehicle based on the calculated control target velocity.

10. A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
-
program instructions that calculate a coasting velocity of an environmentally friendly vehicle at a deceleration event point based on a target coasting distance up to the deceleration event point and a gradient at the deceleration event point; program instructions that calculate a control target velocity of the environmentally friendly vehicle based on a target velocity of the environmentally friendly vehicle at the deceleration event point and the calculated coasting velocity; and program instructions that determine control torque to adjust a velocity of the environmentally friendly vehicle to the target velocity to be output to a powertrain of the environmentally friendly vehicle based on the calculated control target velocity.
