SUSCEPTIBILITY OF ELECTRONIC SYSTEMS FITTED TO VEHICLES FOR DISABLED PEOPLE

The paper describes a series of tests to examine the reliability and immunity to radio interference of several types of electronic control fitted to vehicles for disabled drivers. It provides some simple guidelines for good practice for electronic design to minimise problems from lack of electromagnetic compatibility (EMC). The generic European EMC Directive 89/336/EEC, effective from 1 January 1996, requires all electrical and electronic apparatus to comply with it, unless covered by a product-specific EMC Directive. The Automotive EMC Directive 95/54/EEC specifies a range of test methods that can be performed on whole vehicles or sub-assemblies. It will provide harmonised EMC protection requirements for vehicles and devices intended to be fitted to vehicles. The Transport Research Laboratory (TRL) has conducted tests on several vehicles including cars and camper vans, and especially on: (1) electronic brake and accelerator systems; and (2) electronic steering, brake, and accelerator systems. EMC aspects of any design must be considered early, and form part of the basic design. It is difficult and inefficient to attempt to correct EMC problems in a completed design. Twelve important standard techniques for improving EMC are summarised.
