Automotive Electric Auxiliary Drive System and Control Method

Abstract

The invention discloses an electric assisted driving system for an automobile. The electric assisted driving system for the automobile comprises a battery, a control system and a motor, wherein the control system comprises a control switch, a trigger, a synchronizer, an electric controller, a balancer, a speed limiter, a sample detector and a braking feedback device; the control switch is connected with the battery; the battery is connected with the synchronizer and the electric controller; the trigger is connected with the synchronizer; the synchronizer is connected with an accelerator pedal; the electric controller is respectively connected with the synchronizer, the balancer, the speed limiter, the braking feedback device and the motor; and the sample detector is connected with the balancer. According to the invention, an engine and and the motor are simultaneously used for driving and both bear 50% of energy consumption; therefore, 50% fuel is saved by using 50% electricity, the electric assisted driving system is energy-saving and environment-friendly, environment pollution caused by tail gas is reduced, and technical problems, such as instable performance, heavy battery, high cost and the like, caused by pure electric driving are solved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an electric auxiliary driving system and a control method of an automobile. Background technique [0002] At present, due to the increasing shortage of petroleum resources and the increasingly serious pollution of fuel vehicles, more and more people are investing in the research of alternative products for fuel vehicles. Electric vehicles have the performance of zero emissions and do not use petroleum resources. Electric vehicles The appearance of the electric vehicle solves the problem of energy scarcity very well, so there are electric vehicles of various structures: [0003] 1. Patent No. 201310458830.4 discloses an electric vehicle, including a motor controller, a lithium-ion battery pack, a battery manager, and a motor. The motor controller is connected to the lithium-ion battery pack, and the lithium-ion battery pack is A battery manager is provided, and an...

AI Technical Summary

Problems solved by technology

[0005] Although the above electric vehicles have solved the serious pollution and shortage of resources caused by the original fuel vehicles, they have brought some new technical problems as follows: the performance of electric vehicles is unstable, the battery is heavy, the cost is high, and the capacity is small. Unable to support the long-term driving of electric vehicles, it is not suitable for long-distance driving, and there is waste battery pollution, charging is inconvenient, charging takes a long time, wastes time, etc., so that the application of electric vehicles is subject to certain restrictions

For electric vehicles with better performance on the market, the cost is very high, requiring more than one million units, while for electric vehicles with low cost on the market, their performance is not good, and the speed is limited
