Automatic engine start and stop intelligent trigger method and system based on driving road condition

Abstract

The invention discloses an automatic engine start and stop intelligent trigger method and system based on the driving road condition. Whether the current driving road condition is the red light waiting condition or the congestion condition is distinguished by intelligently recognizing the driving road condition, the red light waiting and staying time is recognized, and unnecessary automatic engine start and stop are avoided. Image reorganization and the automatic start and stop technology on automobiles are combined, the intelligent and automatic start and stop functions can be achieved when the automobiles are in the traffic light waiting state and the congestion state, the automatic start and stop function of the automobiles can be more timely and accurate, fuel is saved to the maximum extent, and emission is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to an intelligent trigger system for automatically starting and stopping an engine based on driving road conditions. Background technique [0002] my country is short of oil resources and highly dependent on foreign countries. At present, oil imports are growing at double-digit percentages every year, while the ratio of motor vehicle oil consumption to domestic oil demand continues to rise. Oil resources are about to enter a state of stretching. With the increasing popularity of automobiles and the increasing number of urban automobiles, the traffic congestion rate has risen sharply, causing problems such as vehicle vibration, noise, and idling fuel waste. Energy saving and emission reduction is imperative. Under the general trend of energy saving and emission reduction, we should first start with the improvement of the driving conditions of motor vehicles. [0003] In order to ...

AI Technical Summary

Problems solved by technology

However, the existing start-stop system is too mechanized, only considering the driving state of the vehicle, not the road conditions of the vehicle, especially in the stop-and-go road section, where the engine starts and stops frequently, which not only fails to achieve the purpose of saving fuel , On the contrary, it causes a waste of fuel, reduces the stability and comfort of the vehicle, and also increases the wear and tear of the engine to some extent.

When waiting for red lights and traffic jams, the self-start-stop system cannot meet the flexibility requirements of car owners

Therefore, in many cases, car owners can only be forced to turn off the automatic start-stop function, which makes this advanced energy-saving and emission-reduction technology a tasteless
