Hello good, I am trying to move the entity of the vehicle, almost everything is ready but it does not move, someone can help me.

You will need to override the travel method. There is a good example of this in the AbstractHorseEntity class.

public void travel(Vector3d travelVector) {
      if (this.isAlive()) {
         if (this.isBeingRidden() && this.canBeSteered() && this.isHorseSaddled()) {
            LivingEntity livingentity = (LivingEntity)this.getControllingPassenger();
            this.rotationYaw = livingentity.rotationYaw;
            this.prevRotationYaw = this.rotationYaw;
            this.rotationPitch = livingentity.rotationPitch * 0.5F;
            this.setRotation(this.rotationYaw, this.rotationPitch);
            this.renderYawOffset = this.rotationYaw;
            this.rotationYawHead = this.renderYawOffset;
            float f = livingentity.moveStrafing * 0.5F;
            float f1 = livingentity.moveForward;
            if (f1 <= 0.0F) {
               f1 *= 0.25F;
               this.gallopTime = 0;
            }

            if (this.onGround && this.jumpPower == 0.0F && this.isRearing() && !this.allowStandSliding) {
               f = 0.0F;
               f1 = 0.0F;
            }

            if (this.jumpPower > 0.0F && !this.isHorseJumping() && this.onGround) {
               double d0 = this.getHorseJumpStrength() * (double)this.jumpPower * (double)this.getJumpFactor();
               double d1;
               if (this.isPotionActive(Effects.JUMP_BOOST)) {
                  d1 = d0 + (double)((float)(this.getActivePotionEffect(Effects.JUMP_BOOST).getAmplifier() + 1) * 0.1F);
               } else {
                  d1 = d0;
               }

               Vector3d vector3d = this.getMotion();
               this.setMotion(vector3d.x, d1, vector3d.z);
               this.setHorseJumping(true);
               this.isAirBorne = true;
               net.minecraftforge.common.ForgeHooks.onLivingJump(this);
               if (f1 > 0.0F) {
                  float f2 = MathHelper.sin(this.rotationYaw * ((float)Math.PI / 180F));
                  float f3 = MathHelper.cos(this.rotationYaw * ((float)Math.PI / 180F));
                  this.setMotion(this.getMotion().add((double)(-0.4F * f2 * this.jumpPower), 0.0D, (double)(0.4F * f3 * this.jumpPower)));
               }

               this.jumpPower = 0.0F;
            }

            this.jumpMovementFactor = this.getAIMoveSpeed() * 0.1F;
            if (this.canPassengerSteer()) {
               this.setAIMoveSpeed((float)this.getAttributeValue(Attributes.MOVEMENT_SPEED));
               super.travel(new Vector3d((double)f, travelVector.y, (double)f1));
            } else if (livingentity instanceof PlayerEntity) {
               this.setMotion(Vector3d.ZERO);
            }

            if (this.onGround) {
               this.jumpPower = 0.0F;
               this.setHorseJumping(false);
            }

            this.func_233629_a_(this, false);
         } else {
            this.jumpMovementFactor = 0.02F;
            super.travel(travelVector);
         }
      }
   }

 

Since your entity doesn't move on it's own and doesn't jump you can remove a good chunk of this but it should get you started. 

Thank you for everything, it has helped me a lot, thank you.
