ENGINE CONTROL SYSTEMS AND METHODS FOR ACCELERATOR PEDAL TIP-OUT |
| 摘要 |
A difference module determines a difference between an engine speed and a transmission input shaft speed. A state control module sets a signal to a first state when a driver releases an accelerator pedal and selectively transitions the signal from the first state to a second state when the difference is less than zero. An immediate torque request module decreases an engine torque request when the signal is in the first state and selectively increases the engine torque request when the signal is in the second state. At least one of: a spark control module that selectively adjusts spark timing based on the engine torque request; and a fuel control module that selectively adjusts fueling based on the engine torque request. |

1. An engine control system of a vehicle, comprising:
a difference module that determines a difference between an engine speed and a transmission input shaft speed; a state control module that sets a signal to a first state when a driver releases an accelerator pedal and that selectively transitions the signal from the first state to a second state when the difference is less than zero; an immediate torque request module that decreases an engine torque request when the signal is in the first state and that selectively increases the engine torque request when the signal is in the second state; and at least one of:
a spark control module that selectively adjusts spark timing based on the engine torque request; anda fuel control module that selectively adjusts fueling based on the engine torque request. |
