Abstract: A method of controlling fuel injection in an engine of a vehicle having an all wheel drive or 4×4 system comprises restricting deactivation of the fuel injection during some deceleration conditions when the vehicle is in an all wheel drive, or 4×4, low gear. According to another aspect, a method comprises restricting deactivation of fuel injection during deceleration operations under all wheel drive, or 4×4 low gear operation; and disabling the fuel injection during at least some deceleration operation under other conditions. Disabling deactivation in an all wheel drive or 4×4 low gear allows a more controlled drivability at a time when any torque disturbance may be magnified and more easily felt by the vehicle driver.

Abstract: A method of controlling fuel injection in an engine of a vehicle having an anti-lock braking system comprises under conditions of degraded operation of an anti-lock braking system, restricting deactivation of the fuel injection during deceleration vehicle operating conditions. According to another aspect, the method comprises under conditions where the anti-lock braking system is functioning, disabling fuel injection during at least some deceleration operations; and under conditions of degraded operation of the anti-lock braking system, restricting deactivation of the fuel injection during deceleration vehicle operating conditions. By considering the functioning of an ABS, it is possible to deactivate fuel injection during some deceleration operations during one condition to realize fuel economy gains and disable the deactivation of fuel injection at another condition to reduce engine stalls. Thus, the deceleration fuel shut off strategy may be used aggressively for improved fuel economy.

Abstract: A method of controlling fuel injection in an engine of a vehicle comprises reactivating fuel injectors based on release or decrease of driver braking during deceleration fuel shut off operation. According to another aspect, a method of controlling fuel injection in an engine of a vehicle comprises reactivating fuel injectors based on release or decrease of driver braking during deceleration fuel shut off; and increasing air flow to a cylinder before reactivation of fuel injectors in response to said release or decrease of driver braking to enhance torque response. The methods allow an engine to exit DFSO earlier by making use the brake input and effort, which provides time to reactivate the fuel injection and stabilize torque control prior to tip-in.

Abstract: An automatic transmission ratio shift control system and method for a powertrain having an engine and multiple-ratio gearing controlled by friction elements actuated by hydraulic pressure, an electronic controller for establishing torque transitions among the friction elements as the gear ratio changes, the engine speed being controlled by an electronic throttle control. The strategy employs an electronic throttle and closed loop engine speed control and uses fuel and air as an energy source to increase engine speed during a power-off downshift. The engine speed is boosted to a level close to the synchronous speed in conjunction with release of the off-going friction element. The on-coming friction element is then applied as the engine speed approaches a desired speed. The engine speed increase is timed to lead an increase in torque converter speed.
