Most bus, truck and off-highway vehicle automatic transmissions today have hydraulic controls similar to the type used on automobile transmissions. Because the number of transmission applications is increasing rapidly and customer demands for improved vehicle performance, greater durability and better reliability are growing, present hydraulic controls are being pushed to their capacity. Overall transmission performance can be improved by replacing hydraulic controls with electrohydraulic controls which incorporate microcomputer-based electronics for intelligence, but continue to employ hydraulics for power to apply the clutches in the transmission.
Important benefits available with a microcomputer-based controls system include: shift point optimization, improved shift point accuracy, transmission-application customization, mechanical linkage elimination, improved fuel economy, and overall powertrain optimization.
