This study was conducted to determine the feasibility of using on-board defect detection and warning devices to monitor safety- critical system variables of passenger cars, trucks, buses and motorcycles. A literature survey and first hand experience were used to establish the current availability, state of the art and costs of sensors, automotive electronics and displays suitable for use in an on-board monitoring system. As well, literature on the contribution of vehicle defects to accidents, outage rates and criticality of safety related variables was reviewed. It was determined that the following variables can be monitored with moderate reliability although in some cases sensor costs are high: tire pressure, brake, windshield washer and power steering fluid level, power brake booster vacuum, brake pressure ratio (front to rear), pedal travel and lining techness, exterior lamp outage and door, hood, trunk lock or latch. A practical system was designed to monitor these variables using currently available components. Price estimates for a prototype system and cost estimates for a system based on 50,000 units were established. /Author/
