Energy distribution methods for hybrid buses

Abstract

The invention discloses energy distribution methods for hybrid buses. By monitoring the quantity information of the buses on the same route within the fixed-length road section ahead in real time, judging whether a traffic jam occurs or not according to the quantity information of the buses, and setting the different energy distribution methods for an engine and a power source, the optimal energy conservation and emission reduction control method is achieved for both roads with heavy traffic and roads with light traffic.

Description

Technical field [0001] The invention relates to an energy distribution method for buses, in particular to an energy distribution method for a hybrid bus for congested road sections. Background technique [0002] With the demonstration operation of hybrid buses in large and medium-sized cities in China, their remarkable energy saving and emission reduction effects have been unanimously recognized. Hybrid buses have also been used more widely. However, as urban traffic becomes more and more congested Especially in areas with high passenger flow, because buses have fixed routes, they cannot bypass congested roads. This makes the energy-saving and emission reduction effects of hybrid buses more obvious. However, hybrid buses are in congested roads and unblocked. If the control strategy of the road section is the same, it will inevitably lead to the non-optimal fuel economy. Therefore, the control strategy for different congestion conditions is of positive significance for improving t...

[0002] With the demonstration operation of hybrid electric buses in large and medium-sized cities in China, its remarkable energy-saving and emission reduction effects have been unanimously recognized by people, and hybrid electric buses have also been more widely used. However, as urban traffic becomes more and more congested , especially in areas with a large passenger flow, because buses have fixed routes and cannot bypass congested roads, this makes the energy-saving and emission-reducing effect of hybrid buses more obvious. If the control strategy of the road section is the same, it will inevitably lead to the suboptimal fuel economy. Therefore, the control strategy for different congestion situations is of positive significance for improving the energy saving and emission reduction effect of hybrid buses.

[0003] Some existing control strategies for congested roads are generally driven by electricity when congested. Although reducing the low-efficiency operation of the engine in congested roads is indeed helpful for energy saving and emission reduction, for hybrid buses, the existing Generally, the power will not be fully stored. Without a deliberate reserve in advance, this is often not enough for driving on congested roads. If the power supply is insufficient, the engine will specifically generate power for the power supply. At this time, the operating efficiency of the engine is very low. It will even increase the overall fuel consumption and emissions. Therefore, it is necessary to predict the congestion information in advance and store more electricity for driving according to the congestion situation.
