Problems solved by technology

However, when driving resistance increases, such as when a large amount of driving power is required due to an ascending slope, high-speed driving due to increased air resistance, overload or traction, etc., HEVs that are performed while driving under normal driving conditions / EV mode transition control may not be suitable for
For example, when the vehicle is driven under high load conditions, the system efficiency may decrease due to frequent mode switching

Abstract

The present invention provides a drive control device and method for a hybrid vehicle. The apparatus includes a vehicle speed calculator configured to detect the travel speed of the vehicle and output information about the detected travel speed; an inclination sensor configured to detect the inclination of the road on which the vehicle is traveling and output information about the detected travel speed information on the inclination; and a mode switching controller configured to determine a driving load of the vehicle based on the traveling speed and the inclination and execute a driving mode of the vehicle based on the magnitude of the driving load.

Description

technical field [0001] The present invention relates to a hybrid vehicle, and more particularly, to a drive control device and method for a hybrid vehicle, wherein the drive control device and method prohibit hybrid electric Vehicle (HEV: hybrid electric vehicle) mode and electric vehicle (EV: electric vehicle) mode switching between to improve fuel efficiency. Background technique [0002] A hybrid vehicle is a type of vehicle that is driven by combining at least two different power sources, and consists of an engine that obtains torque by burning fuel (for example, fossil fuel such as gasoline) and an engine that obtains torque by battery power Electric motor drive. A hybrid vehicle is an environmentally friendly vehicle that uses an engine and an electric motor as an auxiliary power source to reduce exhaust gas and improve fuel efficiency. Research on hybrid vehicles has been actively conducted to meet current demands for improving fuel efficiency and developing environ...
