Electronic devices have been making rapid inroads in automotive products over the past five years. Gains that have been seen in the passenger car segment will naturally extend to the truck and bus markets.

This paper summarizes the market segmentation of this industry, surveys currently available electronic products, and indicates probable direction for future developments. The opportunity is present, the technology is ready, and the challenge is to carry out the application of electronic technology judiciously providing the customer with value for his dollar and making him more competitive in an increasingly competitive business environment.
