AUTOCRUISE CONTROL METHOD FOR HEV AND EV

摘要

The present invention relates to an auto cruise control method for an eco-friendly vehicle. More specifically, the auto cruise control method for an eco-friendly vehicle enables auto cruise torque to be varied in accordance with a gradient and the vehicle speed to achieve a consistent deceleration when an eco-friendly vehicle such as a hybrid vehicle and an electric vehicle drives on a downhill road. Therefore, the present invention provides the auto cruise method for an eco-friendly vehicle enables auto cruise driving point torque to be used until a maximum charging torque area of a motor to enable auto cruise of the eco-friendly vehicle. When a speed difference is generated between the current speed and the target speed in a steel plate furnace, a minimum line of an auto cruise available driving point torque range is varied in accordance with conditions of the gradient and the vehicle speed of the steel plate furnace in order to enable the deceleration to be constantly maintained when the current speed is gathered to the target speed in accordance with an auto cruise driving point.
