Hybrid energy management strategy global optimization system based on large database

Abstract

The invention discloses a hybrid energy management strategy global optimization system based on a large database, and the system comprises a remote database module and a vehicle terminal. The vehicleterminal comprises a data acquisition module, a to-be-processed data storage module, a hybrid vehicle controller, a central processor module, and a personalized data storage module. The data acquisition module includes a GPS module, an accelerator pedal position acquisition module, a brake pedal position acquisition module, a steering torque acquisition module, a transmission gear acquisition module, a six-axis sensor module, an engine operation parameter acquisition module, and a battery charge state acquisition module. The system makes comprehensive use of the IOV (Internet of Vehicles) technology, the sensor technology and the GPS technology, which develop rapidly nowadays. An all-region road condition information large database is built rapidly through the driving information contribution of each vehicle with the system.
