Automatic shift technology of hybrid power engineering vehicle

Abstract

To improve the power performance and reduce energy consumption and environmental pollution, a parallel hybrid loader is taken as a sample to research the automatic shift technology of hybrid power engineering vehicles. The influence of the operating load on the optimal gear was taken into account. The throttle, speed and operating load factor were considered as the control parameters for the new automatic shift control scheme. Energy saving schedule, power shift schedule and comprehensive shift schedule were proposed. Results show under the premise of meeting the normal requirements, the proposed shift schedule is accurate and effective, the gear change and load change have good consistency. The power performance is improved and the energy consumption is reduced.
