摘要: An improved engine torque control method uses existing powertrain sensors and controls to reliably detect and suppress power-hop with minimum degradation of vehicle acceleration. Power-hop is detected by identifying a characteristic wheel jerk magnitude and oscillation frequency based on driven wheel speeds. Once a power-hop condition is detected, the control method computes a desired engine torque output for suppressing the detected power-hop without unnecessarily degrading vehicle performance, based on the wheel jerk magnitude, the engine speed and vehicle acceleration. A combination of engine cylinder fuel cut-off and spark retard is then scheduled for reducing the engine output torque to the desired level for the duration of the power-hop condition. The control method has minimal impact on vehicle cost since it is performed (preferably) by engine or other control software, and has been shown to quickly and effectively suppresses power-hop and its disadvantages without significantly degrading vehicle performance.
