Method and system for intelligent triggering of engine automatic start and stop based on driving road conditions

Abstract

The invention discloses a method and system for intelligent triggering of automatic start and stop of an engine based on driving road conditions. Through intelligent identification of driving road conditions, it is possible to distinguish whether the current driving road conditions are waiting for a red light or in a congested state, and identify the waiting time for a red light , to avoid unnecessary automatic engine start and stop. The invention combines the image recognition with the automatic start-stop technology of the car, which can realize the intelligent automatic start-stop function of the car when the car is waiting at the traffic light or in the congestion situation, so that the automatic start-stop function of the car is more real-time and accurate, and saves fuel to the greatest extent , to reduce emissions.

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
