ABSTRACT:
During gear shift, the fuel control for the engine is switched from the gas pedal to a regulator which regulates it such that the speed of the engine is changed from the speed corresponding to the then-present gear to the speed for the next subsequent gear at a predetermined rate of change of speed with respect to time. A different rate of change of speed may be provided for upshift and downshift operations. A comparator compares the engine speed to the output speed of the gearing and furnishes a shift terminate signal signifying synchronism between the two speeds when the two speeds have a predetermined relationship. A first and second offset signal may be applied to the comparator to allow the engine speed to be somewhat less than the output speed of the gear, and vice a versa, during downshift and upshift respectively.
