Abstract
A controlling device for an automatic speed change mechanism is capable of preventing a sudden acceleration of an automobile against the intention of the driver. The device includes a shift position detector for emitting electric signals indicating the selection state of a manual shift device; a braking detector for emitting electric signals corresponding to the actuation/non-actuation of a braking device; and an electronic controlling device which monitors the electric signals emitted by said shift position detector and said braking detector, controls the said shifting device corresponding to the selection state of a manual shifting device to switch over the connection mode of the speed change mechanism, and during the non-actuation of the braking device, if the manual shifting device commands a switch-over from the non-connection mode to a connection mode, establishes a connection mode having a relatively small reduction ratio compared with the case of brake actuation.
