Idling control system for an automatic transmission providing smooth starting off action

摘要: An automatic transmission has a gear mechanism with forward clutch which is engaged when the to speed stage, one way in cooperation provides first stage by rotation prevention, and brake which, engaged, prevents power output shaft of from rotating direction allow reverse motion vehicle. idling control system for includes engaging selectively either maximum amount or an intermediate amount; second means brake; third controlling mechanism. When driving mode, vehicle substantially stationary, engine idling, braking applied, engages brake. Thereafter, if application terminated, it continues brake, or, ceases be condition, disengages Thereby, rolling backwards down hill while waiting stopped condition positively prevented, mild traffic creep also provided.
