Our view:

Vehicle Complexity will

continue to grow.

In turn it will drive Display

complexities

Are the current Test Systems

and processes equipped to

handle the implications?


Key Considerations for Validation Strategy

1/21/2014 10

How to define optimum Validation Strategy ? Test Iterations – How much is too much?

Choice of Systems - Would we need test iterations on a high cost fully closed loop Test setup or a semi-

automated open loop system or both?

Regression - How to safeguard against fluid specifications?

Validation Strategy Quality of

Testing

Cost Regression

Environment

Manual Testing (Minimal Indirect)

Manual Direct Testing (Subsystem)

Semi Automated Bench (Open Loop)

Fully Automated (Closed Lop)

Would a test system that is configurable to suit your test iteration needs yet

frugal enough to virtually be deployed at each developer bench work for you?

K-Vision,

Solution to automate in-vehicle display validation


Introducing K-Vision

1/21/2014 12

Display Under Test (This can be any in-vehicle or industrial display)

Host

Camera

Fully Integrated

Configurable to cover various test needs

Provides a closed loop regression environments

Frugality through Reuse of existing

software assets/tools

Scalable to cover various display types

K-Vision increases test coverage, efficiency and reduces total cost of ownership

Business benefits

Very low cost of ownership

Easy installation and operation

High productivity



Summary

1/21/2014 14

Cost

Coverage Complexity

Complexities in a vehicle result in multifold

complexities in displays.

These Complexities have implications on

Validation Strategy to achieve a balance of Cost,

Coverage and Quality

K-Vision provides a optimum framework for

Validation Managers to achieve the balance.
