Abstract: The hybrid vehicle commercial vehicle development process based on the traditional chassis is based on the traditional anti-locked branking system (ABS)+electronic stability control (ESC) system commercial vehicle development process, the process of matching traditional fuel engine braking system and matching with the traditional commercial vehicle second-class chassis into hybrid power. The paper describes in detail the hybrid braking system in the traditional fuel brake system to add pure electric mode, matching electronically controlled air compressor, electronically controlled air dryer, ABS+ESC design, reservoir volume, electronically controlled foot brake valve and pipeline matching design. Through the matching calculation and selection, the whole vehicle is carried through various road tests to do a full rang of test verification process and application of braking performance. Through the hybrid tractor braking system braking efficiency verification, braking direction stability and other braking performance test, braking response time, braking deceleration, braking distance, parking braking performance and emergency braking performance to meet the requirements of national regulations.
