ABSTRACT:
An electronic control system suitable for monitoring operation of an automatic automotive gearbox and for verifying actuation thereof in a correct manner. The control system includes stages corresponding to different gear positions, the stages being switchable between set and reset conditions. A control unit is operable to set a particular stage only when the next adjacent stage already is in a set condition. Electrical signals indicating the existing gearbox position are compared with signals defining which stage of the control system is set and operation of the control unit is inhibited if the compared signals do not correspond.
