Abstract: A control system for a vehicle calculates a desired driving force required by the vehicle in response to operating conditions of the vehicle including an amount of operation of an accelerator pedal of the vehicle, and controls the driving force of the vehicle, based on the calculated desired driving force. The desired driving force is corrected depending on whether the vehicle is in a particular operating condition. For example, when the vehicle is in a standing condition while traveling on a road congested with traffic when the desired driving force is corrected in the decreasing direction, the correction amount of the desired driving force in the decreasing direction is corrected to a value closer to zero. The desired driving force is also corrected according to a time period over which the particular operating condition continues.

When the mode is switched between the driving and manual modes, the throttle control section performs switching between the two control modes if the degree of depression of the accelerator is minimum or maximum.

Abstract: A torque shock alleviating device in a hybrid vehicle utilizing both an engine and an electric motor as drive sources, whereby a torque shock is not generated when the rich-spiking of the air-fuel mixture is carried out in order to restore the adsorbing ability of an NOx adsorbing device in the hybrid vehicle. When an engine is operated in a lean burn manner, NOx in an exhaust gas is adsorbed to an NOx adsorbing device provided in an exhaust passage. When the adsorbing ability of the NOx adsorbing device reaches a saturated level, a rich-spiking for temporarily enrichening the air-fuel mixture of the engine is carried out to restore the adsorbing ability of the NOx adsorbing device. When the output torque from the engine is increased by the rich-spiking, a regenerative braking force is generated in a motor, thereby moderating the increase in output torque from the engine by such regenerative braking force to alleviate the torque shock.

Abstract: A control system for an internal combustion engine for a vehicle operable during gear shifting of the automatic transmission effected when the accelerator pedal of the vehicle has been depressed, for changing the output torque of the engine to reduce a shock generated during the gear shifting. Required output torque of the engine for performing the gear shifting is calculated based on a gear shifting duration from the time the gear shifting is started to the time hydraulic pressure for operating a clutch of a lower-speed position of the clutches to be selected by the gear shifting rises. A torque correction amount is calculated based on the difference between the calculated required output torque of the engine and the actual output torque of the engine assumed during the gear shifting. When the gear shifting is started, the output torque of the engine is increased based on the calculated torque correction amount.
