Abstract

The invention relates to a control method of a range-extended type electric vehicle by considering minimum use cost, which adopts a power driving system of the range-extended type electric vehicle. The method comprises the following steps of (1) system control, collecting various types of data and the data of last driving, and waiting for a command of a driver; entering the data to obtain the command of the driver, wherein if the data are not entered, running in the range-extended mode, and if the data of the driver are entered, starting the self-selecting mode; (2) controlling in an expected mode; (3) driving in a pure-electrical mode; (4) driving in the range-extended mode. The method has the advantages that by controlling the use of a range extender, on the premise of not damaging a battery pack, the electric energy is furthest utilized for driving, so the running cost is furthest reduced, and the emission is effectively reduced.

Description

technical field [0001] The invention relates to the field of trams using range extenders, in particular to a control method for trams. Background technique [0002] The shortage of energy and the deteriorating environment make the development of vehicle power system using clean energy more and more urgent. Compared with existing energy-saving and new energy vehicles, pure electric vehicles have considerable advantages in terms of energy saving and environmental protection. It has many advantages such as zero emission during use, high efficiency, and diversified energy sources. But there are also quite a few deficiencies. The most important of these is the low energy density and the resulting short driving range. These directly affect the acceptance of consumers, resulting in a relatively narrow market coverage of electric vehicles as passenger vehicles. One solution is to adopt the extended-range power system, that is, the extended-range tram is used as a transition from...
