At present, electric automobile Regenerative Braking Technology increasingly comes into one's own, but going deep into along with research, technical staff finds
Some technical problem is eager to need to solve, the problem such as optimization in terms of control strategy and the coupling of parameter.And solve above-mentioned asking
The effective ways of topic are exactly the method using simulation test, by the simulation test in product design and advanced development, by automobile
The shortcomings and deficiencies exposure of braking ability processes, then by improving and solving the shortcomings and deficiencies exposing and finding, thus improve
The braking ability of vehicle.Thus, a kind of simple in construction, reasonable in design and processing and fabricating need to be designed and use easy and simple to handle, use
Effective simulated dual motor driven electric car regenerative braking performance test stand, can effective simulated dual motor driven electric car
Regenerative braking operating mode, for improve vehicle braking performances provide reliable basis.
