A DEVICE AND A METHOD FOR VALIDATING AT LEAST ONE DIGITAL INPUT TO A MICRO- CONTROLLER IN AN ELECTRONIC CONTROL UNIT (ECU)

摘要

The invention discloses a device 100 and a method for validating at least one digital input to a micro-controller in an Electronic Control Unit (ECU 10), in accordance with an embodiment of the invention. The method involves generating a pulse voltage 17 by a semiconductor electronic circuit such as transistor 16 in an ECU 10 at step S1. The pulse voltage 17 is supplied through one or more switches 14 to the microcontroller 12 at step S2. At step S3, logical state of the pulse voltage 17 received at the micro-controller 12 through the one or more switches 14 is monitored to validate the digital inputs 13.
