Abstract(s)
The main intension of the project is to develop and implement a standard test
setup and automatic testing scripts to test the Bluetooth module’s audio of the
0KM/Field claimed products of Bosch Car Multimedia Portugal, S.A.
0KM/Field claimed products are the products claimed by the automobile
companies as malfunctioning before going to the final customers. The work
developed in the QMM-FA (Quality Management & Methods – Failure
Analysis) department will be used for testing the characteristics of the Bluetooth
module’s audio to enabling answering the customer’s queries as quickly as
possible and in a standard way.
Currently testing of Bluetooth modules is achieved by using the mobile phones
in the customer mode. Customer mode means that this test is simulates a typical
customer scenario and does not follow any internal testing specifications of
Bosch. Tests strongly depends on external sources (Mobile phones).
Basically, two types of tests are required to evaluate the quality of the CM
products: one is testing and measurement of the characteristics of the products
and another one is functional tests. The functional tests are carried out by using
mobile phones and QMM-FA is already performing a functional test.
The proposed testing setup is framed by using R&S Audio Analyzer – UPL,
R&S Signal Generator, R&S Programmable Power Supply and Bosch
BLAUBOX and BLAUKIT. This setup is mainly used to test the audio
streaming and other characteristic of the BT module’s audio.
Bosch having a diverse variety of CM products maximum of the products are
having a Bluetooth module. The developed test plan was implemented in the
“NISSAN A IVI SCOPE_1” product. Test script was developed using blk
programming codes in BLAUKIT (Bosch’s internal platform). All the used equipment are connected through GPIB connector to configure & acquire
remotely.
Notion of this proposed test plan will be the same for all the other 0KM/Field
claimed products, only the testing variables and the way of communication with
the product’s modules are different depends on the product’s specification.
Bosch standards and specifications are framed according to the customer
specification of each product. For “NISSAN A IVI SCOPE_1” product, Bosch
Groups already having a set of requirements from the NISSAN Group of
companies. In Bosch manufacturing plant, manufactured products should
accomplish the customer requirements.
This test setup is framed to test the BT module’s audio according to the Bosch
testing standards and specifications to ensure the quality and functionality of the
Bluetooth audio of “NISSAN A IVI SCOPE_1” product. By using the proposed
test plan it enables the claimed product test and analysis the characteristics of
the Bluetooth Audio in the stipulated time with automatic testing.
