Energy-saving driving system for new energy automobile

Abstract

The invention provides an energy-saving driving system for a new energy automobile. The energy-saving driving system for the new energy automobile comprises a CAN bus, a battery unit, a driving motor, a differential mechanism driving shaft and an anti-skid brake system (ABS) control system. The battery unit is connected with an inverter, a brake, a power steering pump and a direct current / direct current (DC / DC) converter. The inverter is connected with a power converter which is connected with the driving motor. The driving motor is connected with a speed changer which is connected with the differential mechanism driving shaft. The CAN bus penetrates through the whole driving system. The driving system is high in energy conversion efficiency, good in energy-saving effect, small in occupied space, high in stability, safety and integration degree and high in reliability in the information transmission process, so that the using performance of the whole automobile is improved, the service life is prolonged, and the cost of the automobile is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an energy-saving drive system for new energy vehicles. Background technique [0002] The problem of energy depletion and environmental pollution has become an urgent problem to be solved in today's society, and it is also a major challenge facing the world and the crux of the problem that restricts the sustainable development of the automobile industry. In order to alleviate this situation, people are actively exploring and researching green renewable energy and new vehicle driving methods, thus new energy vehicles were born. In new energy vehicles, through the comprehensive utilization of machinery, computers, power electronics, intelligent control, new energy and other technologies, the power system is controlled to flexibly adjust according to the actual operating conditions of the vehicle, so as to improve the fuel economy of the vehicle , reduce emissions and re...

AI Technical Summary

Problems solved by technology

The DC-DC converter and the driver in the motor system are mainly composed of power switching devices, such as IGBT (Insulated Gate Bipolar Transistor). If these devices are used more in the system, the cost is high, the volume and weight are large, and the DC-DC conversion Efficiency may become lower, increasing energy consumption

In addition, new energy vehicles have relatively strict requirements on space and volume, and each controller is independently distributed and arranged, which not only occupies a large space, but the technology is scattered and controlled by different manufacturers, which also brings certain difficulties to the troubleshooting of the whole vehicle
