Diesel engine speed control with handling of driveline resonances
A vehicular driveline transfer engine torque to the wheels. Resonances
in the elastic parts of the driveline are important to handle when
control of the engine and the transmission is optimized. Traditional
diesel engine speed control maintains a well-damped engine speed set
by the driver. However, the resonance modes of the driveline are
easily excited by accelerator-position changes or by road
disturbances. A speed-control strategy is proposed that includes the
behavior of the driveline, and reduces driveline resonances and
vehicle shuffle by engine control. Implementation shows significant
reduction, also when facing nonlinear torque limitations from maximum
torque and diesel smoke delimiters.
