초록 ▼

Described herein is a drive-by-wire vehicle engine output control system. The system permits good-response acceleration by a driver\s simple and reasonable operation, i.e., by operating an accelerator pedal and also a prompt response even when a sudden load change occurs. Further, the system permits precise speed control by simple equipment even when the deviation of a vehicle speed from a target vehicle speed is large. Output changes of an engine can be controlled within a permissible output change range by (a) comparing a target autocruise engine output with an acceleration demanding ending output, choosing the larger engine output and then controlling the engine to give the larger engine output, (b) controlling the engine to achieve a target autocruise engine output obtained from a speed correction torque and a running load torque or (c) limiting an engine control quantity on the basis of a permissible output change value.

대표청구항 ▼

A drive-by-wire vehicle engine output control system for controlling an output of an engine in accordance with a degree of depression of an accelerator pedal by a driver and a mode of operation of a vehicle, comprising: a vehicle speed detection means for detecting a running speed of the vehicle; Engine output adjusting means for adjusting the output of the engine; target engine output setting means for setting, based on the running speed detected by said vehicle speed detection means, a first target value of engine output torque as a target being required to maintain the running speed of the vehicle at a predetermined speed irrespective of depression of said accelerator pedal; acceleration demand engine output setting means for setting a second target value of engine output torque as an acceleration demand engine output torque, said second target value being required to accelerate the vehicle in accordance with the degree of depression of the accelerator pedal when the accelerator pedal is depressed; selector means for comparing the target engine output torque set by said target engine output setting means with the acceleration demand engine output torque set by said acceleration demand engine output setting means obtain a greater engine output torque therefrom, and selecting said greater engine output torque as a target engine output torque; target control quantity setting means for setting a target control quantity for said engine output adjusting means, said target control quantity being required to bring the output torque of the engine close to the target engine output torque selected by said selector means; and control means for controlling said engine output adjusting means in accordance with the target control quantity set by said target quantity setting means.
