Vehicle brake pedal interlock for heavy vehicle neutral to engaged gear shift

摘要

A heavy vehicle transmission is provided with an interlock that prevents movement from neutral into an engaged speed ratio if the vehicle is under start from stop conditions. The interlock ensures that the operator does desire to engage a gear prior to effecting the engagement. The method is also incorporated into a control for the transmission. The method and control are most preferably incorporated into a type of automatic transmission which has an automatic clutch that does not require any operator input.
