Abstract
A transmission-controlling system capable of controlling a transmission of a vehicle having both an automatic transmission (AT) and an anti-lock brake system (lBS), without damaging the ABS function is disclosed, in which both a change-speed graph for normal operation and a change-speed graph for acquiring automatic engine brake are incorporated in an AT controller and, when a signal noticing that ABS is in operation is not given from an ABS controller, the AT controller functions to shift gear speed according to the change-speed graph for aquiring automatic engine brake to thereby attain automatic engine brake and, when the signal noticing that ABS is out of operation, the AT controller functions to shift gear speed according to the change-speed graph for normal operation. In the latter case, the automatic engine brake is not acquired, and hence the ABS function is not possibly damaged, and the vehicle does not receive a severe shock.
