Abstract

A method for starting a vehicle engine includes determining a throttle angle command output based on a throttle adjustment parameter. The throttle angle command output may be further adjusted based on a learned compensation adder and may be based on a number of vehicle engine starts. A throttle angle corresponding to the throttle angle command output is provided.

Description

technical field [0001] The invention relates to a method of controlling engine starting in a vehicle. Background technique [0002] A hybrid electric vehicle (HEV) utilizes a combination of an internal combustion engine and an electric motor to provide the power needed to propel the vehicle. This arrangement provides improved fuel economy over vehicles with only an internal combustion engine. One way to improve fuel economy in HEVs is to shut off the engine when it is running inefficiently and when it is not needed to propel the vehicle. In these cases, electric motors are used to provide all the power needed to propel the vehicle. When the driver's power demand increases such that the electric motor can no longer provide enough power to meet demand, or if the battery state of charge drops below a certain level, the engine must start quickly and smoothly in a manner that is obvious to the driver . [0003] Engine starting in an HEV may occur while the vehicle is operatin...
