Abstract

Hydraulic control units (HCUs) are widely used as precise pressure regulators for the composite brakes in electric vehicles. The braking comfort can be improved by appropriate braking intention classification and identification. A braking intention classification method is developed to improve braking comfort that classifies the braking intention as normal deceleration, emergency braking and a pressure following pattern. The pressure control method is then based on the classification results. The on-line braking intention identification method uses multiple sensors and a neural network. Simulations and tests show that the braking comfort and safety are improved by this method.

Key words
