Engine warmup on pedal-start vehicle

Abstract:

A method for cold engine starting in a pedal-start vehicle that comprises determining an ICE temperature value of an internal combustion engine of the vehicle upon starting the engine via depression of an accelerator, then comparing the ICE temperature value to a predetermined ICE temperature threshold value. Thereafter, when the ICE temperature value is below a predetermined ICE threshold value, controlling operation of the engine such that an RPM of the internal combustion engine remains within a predetermined idle RPM range for a predetermined amount of time, regardless of throttle control commands from the accelerator pedal of the vehicle, or when the ICE temperature value is equal to or greater than the predetermined ICE threshold value, or controlling operation of the internal combustion engine in accordance with the throttle control commands from the accelerator pedal.
