Wheel collider and joystick

Hi all you great minds.

I am trying to connect my mobile joystick to my car, so that I can make a small racing game on my mobile phone.

I am having an issue with connecting the virtual joystick to my car. I got the car rolling by using my arrows, but I can't make the connection between the joystick input and the car itself.

This code moves the car:

 for (int i = 0; i < 2; i++)
     {
        wheelColliders[i].motorTorque = accelerate * maxTorgue;
        
     }

This code shows me the coordinates for the position of the joystick:

   public virtual void OnDrag(PointerEventData ped)
 {
     Vector2 pos = Vector2.zero;
     if (RectTransformUtility.ScreenPointToLocalPointInRectangle(bgImg.rectTransform, ped.position, ped.pressEventCamera, out pos))
     {
         pos.x = (pos.x / bgImg.rectTransform.sizeDelta.x);
         pos.y = (pos.y / bgImg.rectTransform.sizeDelta.y);

         float x = (bgImg.rectTransform.pivot.x == 1) ? pos.x * 2 + 1 : pos.x * 2 - 1;
         float y = (bgImg.rectTransform.pivot.x == 1) ? pos.y * 2 + 1 : pos.y * 2 - 1;

         inputVector = new Vector3(x, 0, y);
         inputVector = (inputVector.magnitude > 1) ? inputVector.normalized : inputVector;

         //MoveJoystic image
         joystickImg.rectTransform.anchoredPosition = new Vector3(inputVector.x * (bgImg.rectTransform.sizeDelta.x/3), 
                                                                   inputVector.z * (bgImg.rectTransform.sizeDelta.y/3));
         Debug.Log(pos);
     }
 }

I thought that the solution could be in this code, but I cant find it:

if (moveJoystick.inputVector != Vector3.zero) { movement = moveJoystick.inputVector;

     }

Does anyone of you guys have any experience with this type of work?
