Memory circuit for electric vehicle controllers is automatically holding electromagnetic circuit connected to engine controller, can pass binary electrical operating parameter to controller

摘要

The memory circuit (3) is connected to the vehicle's engine controller (16) and can pass the binary electrical operating parameter to the controller. The memory circuit is an automatically holding electromagnetic circuit in the form of an electromagnetic relay circuit with a field generating element and a switching element (8) with two states corresponding to the binary states of the operating parameter. Independent claims are also included for the following: a method of storing a binary electrical operating parameter for a vehicle.
