Abstract
PURPOSE: To make an engine brake actuate accurately by conducting the shift down automatically only when a driver detaches his foot from an acceleration pedal and works a brake pedal.
CONSTITUTION: An electronic control system is linked to a cut-back solenoid 23, a 1-2 shift solenoid 24, a 2-3 shift solenoid 25, a vehicle-speed sensor 26, a throttle- opening sensor 27 and an acceleration pedal 28 and detects the time when they are released. As a means for detecting the idling, an idling switch 29 which turns on when the acceleration pedal 28 is released is constituted in the interrelation with a computer 32, while as a means for detecting the operation of a brake, which is linked to a brake pedla 30 and detects the time of working thereof, a brake switch 31 turning on when the brake pedal 30 is stepped on is constituted in the same way.
