Specific embodiment
With reference to the accompanying drawings and examples this utility model is further described, but is not intended as to this utility model
The foundation of restriction.
The system that a kind of pure electric automobile adjusts steering wheel weight according to speed, as shown in figure 1, including DC/AC inverters
1st, car load CAN network 2, oil pump 3, entire car controller CAN4, battery management system 6, charger 7, electric machine controller 8 and instrument 5；
The oil pump 3 and car load CAN network 2 are connected with DC/AC inverters 1 respectively, and DC/AC inverters 1 are by wheel half
Footpath, gear ratios, back axle total reduction speed are than calculating speed plus rotating speed of automobile engine；
