Embodiment Construction

[0027] The control method of the plug-in hybrid electric passenger car that the present invention proposes, its flow chart is as follows figure 1 shown, including the following steps:

[0028] (1) Obtain the traffic speed-time historical statistical information of the bus line from the urban traffic management center, and classify the status of vehicles passing through the road congestion section according to the obtained information: the vehicle passing through the congested road section during the congestion time is the first level, and the vehicle passing through the non- Congested road sections are grade 2, vehicles passing through congested road sections during non-congestion time are grade 3, and vehicles passing non-congested road sections during non-congestion time are grade 4;

[0029] (2) For each of the above congestion levels, set the real-time energy allocation method of vehicles:

[0030] In the first level of congestion, the vehicle is driven by pure electricity,...

Abstract

The invention relates to a control method of a plug-in hybrid power bus, belonging to the technical field of the control of hybrid power buses. The method comprises the following steps of: obtaining present vehicle position information by using a GPS (Global Position System) navigation device and a digital map stored in a vehicle-mounted information unit, judging road congestion levels at the temporal position by combining vehicle speed-time history counting information of an urban fixed line stored in the vehicle-mounted information unit; and carrying out real-time optimization and adjustment for the energy distribution of the vehicle according to the information including different congestion levels, the present vehicle position, and power battery electric quantity and the like. The method disclosed by the invention can effectively and reasonably distribute the energy of the plug-in hybrid power bus running on fixed lines, so that the fuel oil consumption and the pollutant emission are reduced and the fuel oil economy is enhanced.

Description

technical field [0001] The invention relates to a control method for a plug-in hybrid electric bus, in particular to a multi-energy coordinated optimization control method for a plug-in hybrid electric bus based on GPS navigation and traffic speed-time historical statistical information, which belongs to the hybrid electric bus control technology field. Background technique [0002] With the demonstration operation of hybrid electric buses in various large, medium and small cities in China, its remarkable energy-saving and emission-reducing effects have been unanimously recognized by people. There is still a lot of room for performance improvement. As an upgraded version of conventional hybrid electric buses, plug-in hybrid electric buses can realize the full utilization of cheaper and clean energy by connecting the power battery to the grid for charging during the low power consumption period at night. In the form of self-sufficiency in the battery power of the bus, the p...
