An electrically powered fuel pump in an electronic returnless fuel delivery system for an internal combustion engine is controlled during transient engine operating conditions. A controller senses an operating parameter to infer whether a transient engine operating condition exists. Then, the controller generates an estimate of a fuel pump correction signal based on this inference. The correction signal is generally sufficient to cause the fuel pump to respond to the transient condition, by supplying a generally correct amount of fuel, prior to the engine requiring a change in fuel quantity.

A multiple ratio automatic transmission having a hydrokinetic torque converter in an automotive vehicle driveline wherein the torque converter has a controllable bypass clutch and wherein provision is made for changing the clutch capacity during a ratio change to reduce undesirable torque fluctuations in the driveline, thus improving shift quality while maintaining optimum hydrodynamic torque converter efficiency.

Electronically controlled bypass clutch using target slips based on

An electronically controlled multiply ratio transmission for an automotive vehicle powertrain having a hydrokinetic torque converter with a bypass clutch, solenoid operated shift valves under the control of an electronic microprocessor that receives signals from an output shaft speed sensor, an engine speed sensor, a driver controlled drive range selector position, an engine throttle position sensor, and other powertrain operating variables, the bypass clutch having a controlled slip characteristic.

Control system for controlling engagement of an automatic transmission

A mass airflow based control system for an internal combustion engine is provided which is capable of inferring cylinder air charge during non-steady state periods of operation of the engine. The control system infers cylinder air charge from values of rotational engine speed, air mass flow inducted into the engine, inlet air temperature, engine coolant temperature, and barometric pressure. The control system employs the inferred cylinder air charge value for air/fuel ratio control.

Controlling the speed of an engine used with an automatic transmission to reduce tip in jerk includes determining any difference between transmission gearset speed and engine speed. Engine speed is increased if it is below transmission gearset speed so as to reduce any speed differential between the engine and transmission gearset.
