Torque Correcting Strategy in Driving Control of New Energy Vehicle

Because the problems of energy and environment become more and more seriously, Li-Ion power battery turns more popular by the new energy vehicles. However, if it cannot be used correctly, the power battery can be over charged and over discharged, and the safe hidden trouble will cause environment pollution. This thesis takes the pure electronic vehicles as an example, points out that a kind of torque correcting strategy in the driving control based on the max charge and discharge power, deducts and identifies the parameters to the Power battery equivalent circuit model based on RC network. The result shows that: we can get the max charge and discharge power based on this model and makes the work of correcting torque at optimal work points. This strategy not only can make sure the driving functions of the vehicles, but also can prevent the errors of using power batteries, then avoids the environment pollution.
