A control system for an engine is provided. The control system includes an accelerator opening acquiring module for acquiring an opening of an accelerator, a target acceleration setting module for setting a target acceleration of a vehicle based on the accelerator opening acquired by the accelerator opening acquiring module, and an engine control module for adjusting an engine torque to achieve the target acceleration set by the target acceleration setting module. Within a predetermined range of the accelerator opening, the target acceleration setting module sets the target acceleration corresponding to the accelerator opening acquired by the accelerator opening acquiring module, to cause a change of the target acceleration with respect to a change of the accelerator opening to be substantially constant regardless of an operating state of the vehicle, the predetermined range including a value of the accelerator opening at which the target acceleration becomes zero.

Control device for engine

A control system for an engine adjusts an engine torque based on an operation of an organ-type accelerator pedal for pivoting about a supporting point. The control system includes an accelerator opening acquiring module for acquiring an accelerator opening, a target acceleration setting module for setting a target acceleration of a vehicle based on the acquired acceleration opening, and an engine control module for adjusting the engine torque to achieve the set target acceleration. The target acceleration setting module sets the target acceleration corresponding to the acquired accelerator opening by using a predetermined range of the accelerator opening including a value at which the target acceleration becomes zero. The predetermined range is set such that a pedal reaction force F (N) applied from a predetermined position of the accelerator pedal when the accelerator opening is within the predetermined range is within a range of 2.5&#x2266;F&#x2266;26.

A control system for an engine is provided, which includes an accelerator opening acquiring module for acquiring an accelerator opening, a target acceleration setting module for setting a target acceleration of a vehicle based on the acquired accelerator opening, and an engine control module for adjusting an engine torque to achieve the set target acceleration. By utilizing first to third ranges defined for the accelerator opening and first to third acceleration characteristic maps, the target acceleration setting module selects one of the first to third acceleration characteristic maps according to a range under which the acquired accelerator opening falls among the first to third ranges, and the target acceleration setting module sets the target acceleration corresponding to the acquired accelerator opening based on the selected map.
