Optionally, a rotating shaft 21 is inserted into one end of the rotating swing arm 20, two ends of the rotating shaft 21 are connected to the base 10, and the rotating swing arm 20 rotates relative to the base 10 through the rotation of the rotating shaft 21.

One end of the pedal 41 is rotatably connected to the base 10. The pedal 41 has a substantially plate shape, and one end thereof is rotatably connected to the base 10 without limitation, and for example, the rotatable connection may be achieved by a hinge connection. The pedal 41 includes opposite upper and lower surfaces, the upper surface being adapted to be stepped by a user so that the pedal 41 rotates relative to the base 10.

The size of the rotation angle of the rotating swing arm 20 is related to the size of the throttle.

Referring to fig. 1 and 4, in the driving process of the vehicle 1000, the distance sensor 110 on the vehicle 1000 detects the distance of the obstacle and sends a distance signal to the vehicle controller 120, and the vehicle controller 120 can determine whether the vehicle 1000 is dangerous according to the distance signal and determine whether to send a danger signal to the accelerator pedal assembly 100. Specifically, when it is determined that the vehicle 1000 has a danger, a danger signal is transmitted to the accelerator pedal assembly 100, and when it is determined that there is no danger, the danger signal is not transmitted to the accelerator pedal assembly 100.

When the included angle between the rotary swing arm 20 and the initial position is 0 degree, the opening degree of the accelerator is 0, and oil can not be supplied. When the rotary swing arm 20 is angularly varied with respect to the initial position, the angular variation can be modulated to various possible control signals to control the size of the throttle. For example, the angle change is modulated to a voltage, and the device for modulating may be the safety controller 30, the vehicle control unit 120, or other additional devices, without limitation. After the angle is modulated to be the voltage, the voltage signal is input into a device for controlling the opening degree of the accelerator, for example, the oil pump is input, the oil pump controls the opening degree of the accelerator according to the voltage, namely, the voltage is positively correlated with the opening degree of the accelerator. Thus, the larger the included angle of the rotary swing arm 20 relative to the initial position is, the larger the voltage is, the larger the accelerator opening degree is, the smaller the included angle is, and the smaller the voltage is, the smaller the accelerator opening degree is. In summary, normal driving operation is achieved.
