Abstract
PURPOSE: To realize the reasonable saving of fuel by neutral travelling obtained from controllably changing over a transmission position to the neutral state in the detection of coasting requirement of an automobile, while releasing the transmission position from the neutral state in the detection of braking.
CONSTITUTION: A microcomputer 14 for implementing digital computational processes according to a control program including a predetermined neutral control program is provided to generate a control command for the neutral travel and other control commands. Namely, when the respective signals from an acceleration sensor 9, brake switch 10, neutral switch 11, release switch 12 and descent sensor 13 in the neutral travel control are used for detecting the coasting condition of an automobile, a neutral valve 7 provided in a transmission mechanism 4 is driven to forcibly change over said mechanism 4 to the neutral state. Also, said neutral state is controllably released in the detection of braking.
