Abstract

An apparatus comprises a cruise control section to control an engine output according to an acceleration/deceleration demand set according to an acceleration/deceleration demand from a driver or a cruise control demand set to match an actual vehicle speed to a preset vehicle speed or to match a vehicle distance relative to a forward-going vehicle to a preset value, whichever demand is greater, a speed shift control section to shift gears and to control the engine output, and a switch control section to switch the cruise control section and speed shift control section according to their priority order. The speed shift control section, upon being switched by the switching control section to the cruise control section after the completion of the shift changing, returns the engine output back to that previous switching state based on the cruise control section.

Claims

1. An engine output control apparatus comprising:

a cruise control section configured to control an engine output according to an acceleration/deceleration demand set according to an acceleration/deceleration demand from a driver or a cruise control demand set to match an actual vehicle speed to a preset vehicle speed or to match a vehicle distance relative to a forward-going vehicle to the preset vehicle speed, whichever demand is greater;

a speed shift control section configured to shift gears and to control the engine output according to the actual vehicle speed; and

a switching control section configured to switch the cruise control section and speed shift control section according to a priority order, wherein

the speed shift control section, upon being switched to the cruise control section by the switching control section after the completion of the shift, controls the engine output based on the next cruse control section.

2. An engine output control device according to claim 1, wherein the priority order of the speed shift control means is higher than that of the cruise control means.

3. An engine output control apparatus comprising:

a speed restriction control section configured to control an engine output according to an acceleration/deceleration demand set according to an acceleration/deceleration demand from a driver or a speed restriction demand set never to allow the actual vehicle speed to reach a predetermined vehicle speed, whichever is smaller;

a speed shift control section configured to shift gears and to control the engine speed according to the actual vehicle speed; and

a switching control section configured to switch the speed restriction control section and speed shift control section according to a priority-order, wherein

the speed shift control section, upon being switched next by the switching control section to the speed restriction control section after the completion of the shift, controls the engine output based on the speed restriction.

4. An engine output control apparatus according to claim 3, wherein the priority order of the speed shift control section is higher than that of the speed restriction control section.
