Embodiment 1

[0049] Reference Figure 1 , the present embodiment provides an electric vehicle start control system, comprising a throttle knob 12, a speed detection module 13, a road surface detection module 17, a first body attitude detection module 14, a second body attitude detection module 15, a speed detection module and a controller module 11. Throttle knob 12, vehicle speed detection module 13, road surface detection module 17, the first body attitude detection module 14, the second body attitude detection module 15, speed detection module are connected to the controller module 11.

[0050] Throttle rever 12 is used to output the throttle signal;

[0051] Vehicle speed detection module 13 adopts Hall sensor, mounted on the front wheel, for outputting a vehicle speed signal representing the speed of the vehicle, the controller module 11 can calculate the actual speed of the electric vehicle S0 according to the speed signal.

[0052] The speed detection module adopts Hall sensor, which is ...

Embodiment 2

[0063] Reference Figure 2 , on the basis of example one, the present embodiment further provides a electric vehicle starting control method, comprising:

[0064] A01, Detection of throttle signal, vehicle speed signal, speed signal, first attitude signal and second attitude signal.

[0065] A02, according to the speed signal, speed signal to determine whether the rear wheel of the electric vehicle is slippery, if so, reduce the power of the hub motor;

[0066] Specifically, S0 is set to the actual speed of the electric vehicle, S1 is the measured speed of the electric vehicle, N is the speed of the hub motor, and S1 = F (N); Y1 = S1-S0; when the value of Y1 is greater than 0, the controller module 11 determines that the rear wheel of the electric vehicle is in a sliding state; when the value of Y1 is greater than 1 and less than the first threshold, the controller module 11 reduces the power of the hub motor to %M1 of the expected power corresponding to the throttle signal; when t...

Embodiment 3

[0070] On the basis of example 1, the present embodiment also provides an electric vehicle starting control system, which is mainly designed for the fork structure of the electric vehicle, to a certain extent can limit the sliding of electric vehicles, as follows:

[0071] Reference Figure 3 The fork of the electric vehicle includes a fork 5 and a column set on the fork 5, the fork 5 is used to install the front wheel, brakes and other components; the column can be rotated to the sleeve 2 at the front of the frame 6, and the top of the column is used to install the front of the car head and other components.

[0072] Reference Figure 4 The column comprises an upper column 3 and a lower column 4, the upper column 3 is connected to the sleeve shaft 2; the bottom end of the upper column 3 is opened with a containment slot 31, the containment slot 31 is installed with a first drive motor 71, the first drive motor 71 is fixed by a bolt penetrating radially along the upper column 3, and...
