Problems solved by technology

However, due to various driving conditions, especially the driver's driving tendency, the correlation between regenerative torque and mileage cannot be accurately determined according to various driving conditions
[0006] In particular, when driving torque and regenerative torque are continuously switched based on a specific diving style (ie, driving tendency), unnecessary energy recirculation may be frequently generated and vehicle mileage may be reduced, thereby cause poor fuel efficiency

Abstract

Disclosed is an apparatus and method of controlling motor torque of a vehicle capable of increasing vehicle mileage and improving fuel efficiency by adjusting regenerative torque of a motor according to a driving tendency of a driver when a vehicle is in a coasting mode by detecting a driving tendency of a driver by analyzing the number of brake pedal operations and engaging depth of a brake pedal for a predetermined period.

Description

technical field [0001] The present invention relates to an electric motor torque control device for an environmentally friendly vehicle, and more particularly to an apparatus and method for controlling electric motor torque for an environmentally friendly vehicle, which can be adjusted by adjusting the The regenerative torque of the electric motor is used to increase vehicle range and improve fuel efficiency. Background technique [0002] Demand for environmentally friendly vehicles has increased in accordance with the need for improvement in fuel efficiency for vehicles and exhaust regulations. Environmentally friendly vehicles include fuel cell vehicles, electric vehicles, plug-in electric vehicles, hybrid vehicles, etc., and include one or more electric motors (motor) and engine (engine), and battery pack (battery), inverter, Hybrid starter generator (HSG: hybrid starter generator), and engine clutch, in which the battery pack stores high-voltage power for driving the mo...
