Abstract:
1. A driving method for an electric vehicle, comprising: using an angle sensing unit to sense a tilting angle of the electric vehicle on a road; adjusting a control signal according to a change of the tilting angle; using a power driving unit to receive the control signal to generate a driving current; and using an electric motor to receive the driving current and drive the electric vehicle so as to increase a torque force of the electric motor when the electric vehicle is on an uphill road; wherein adjusting the control signal according to the change of the tilting angle comprises: increasing the driving current of the electric motor to increase the torque force of the electric motor when the tilting angle remains greater than a predetermined uphill angle for a predetermined time, and determining whether the tilting angle is in a first angle range or a second angle range when the tilting angle is greater than the predetermined uphill angle; increasing the driving current of the electric motor to a first current magnification by the control signal when the tilting angle remains in the first angle range for the predetermined time; and increasing the driving current of the electric motor to a second current magnification by the control signal when the tilting angle remains in the second angle range for the predetermined time, wherein the first current magnification is less than the second current magnification.
