Publication number: 20130151089Abstract: An engine torque compensation method is based on a change in the concentration of ethanol for a Flexible Fuel Vehicle (FFV). In the method, a concentration of ethanol in fuel that is supplied to an engine is acquired. A driver-required torque based on an opening rate of a throttle valve depending on manipulation of an accelerator by a driver is calculated. A torque correction factor depending on the opening rate of the throttle valve and the concentration of the ethanol is calculated. A final driver-required torque is obtained by multiplying the torque correction factor by the driver-required torque.Type: ApplicationFiled: June 26, 2012Publication date: June 13, 2013Applicants: Kia Motors Corporation, Hyundai Motor CompanyInventor: Soon Ki Kim
