Driving control method for hybrid vehicle

摘要

A driving control method for a hybrid vehicle has state of charge (SOC) ranges including a high SOC range, an intermediate SOC range and a low SOC range, and a plurality of power distribution strategies corresponding to the respective SOC ranges. The driving control method controls the hybrid vehicle using a power distribution strategy corresponding to an SOC range to which a current SOC of the hybrid vehicle belongs. When a speed of the hybrid vehicle is high or low and is outside a predetermined range, boundary values of the intermediate SOC range and the low SOC range among the SOC ranges are increased.

1. A driving control method for a hybrid vehicle having state of charge (SOC) ranges and a plurality of power distribution strategies, the driving control method comprising:
controlling, by a controller which controls power distribution of the hybrid vehicle and charge and discharge of a battery, the hybrid vehicle using a power distribution strategy corresponding to an SOC range to which a current SOC of the battery belongs, wherein the SOC ranges include a high SOC range, an intermediate SOC range, a low SOC range, each of which includes an upper limit and a lower limit, and the plurality of power distribution strategies correspond to the respective SOC ranges, wherein when a speed of the hybrid vehicle is outside a reference speed threshold, the upper and lower limits of the intermediate SOC range and the low SOC range are increased, and wherein a plurality of driving modes are provided, and upper and lower limits of each of the high SOC range, the intermediate SOC range, and the low SOC range are set in each of the driving modes.
