Could I inherit from a custom module in odoo?

Question

I have custom module in my odoo called "x_vehicles"

Could be possible to inherit from this module to overwrite the create method??

I've this code

class extend_vehicle(models.Model):
    _inherit = 'x_vehicle'

    @api.model
    def create(self, vals):

        # Do something...

        return super(extend_vehicle, self).write(vals)

But I get this error

I don't know if I need to extend from other model or do something special...

Please, Could anyone help me??

EDIT: Maybe with the name "custom module" I've made a mistake... It's a module built inside odoo, not as an external module. I don't have the code of the module. It was built with the tool that odoo provides.

I can't extract the structure because it's a little bit complicated extract all the functionality, so, I need to try to inherit from that module

I'll hope that this could be more specific

EDIT 2: I think that here is the problem... If I try to install the module that inherit the functionality, in the tab "Technical data" I can see that the model is Unknown... but I don't know why...

Also, this is my actual openerp.py file

{
    ...
    'category': 'Automation',
    'version': '1',
    # any module necessary for this one to work correctly
    'depends': ['base','x_vehicle'],
    # always loaded
    'data': [

    ]
}

Yes it is possible.

Open __openerp__.py file and update with following key

"depends" : [
    'base', 'list_of_core_module', 'your_custom_module_name'
],

Where

list_of_core_module like sale, purchase, account etc...,

your_custom_module_name where you have declared x_vehicles class

Restart your server and upgrade current module as you work on.
