Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
In a first aspect, embodiment of the disclosure provides a kind of overspeed protection method, the method is mainly used in vehicle
Controller side, as shown in Figure 1, the method includes：
101, when the current rotating speed of driving motor be more than hypervelocity error protection threshold value when, judge current state whether meet to
The condition of battery system charging.
Currently, most of electric vehicles all include this several portion of entire car controller, electric system, battery system and brake system
Point.Wherein, entire car controller is vehicle " brain ", can control each controller of vehicle；Electric system includes driving motor
And electric machine controller, the torque demand for responding entire car controller；Battery system includes battery pack and battery management system, is
Vehicle provides electric energy；Brake system includes brake disc, can realize vehicle by controlling the frictional force between brake disc and wheel
Braking.
In vehicle travel process, electric machine controller can acquire driving motor current rotating speed in real time, and judge current rotating speed
Whether it is more than hypervelocity error protection threshold value, if more than the hypervelocity error protection threshold value, then entire car controller is notified to enter hypervelocity and protect
Shield pattern.When entire car controller knows that current rotating speed is more than hypervelocity error protection threshold value, motor control when in order to ensure energy feedback
Device processed is not burned, and can first judge whether current state meets the condition to charge to battery system, so as to true according to judging result
Determine the mode of energy feedback.
