Technology in the Vehicle


▌ Simple Equation

▌ the more sensors are integrated …

▌ the more assistance features will be available ….

▌ the more complex the systems will become*.

05-02-2015

▌ * Up to an certain level of sensors and ecu-power the innovation will mostly be driven by software.


Perspective

Technological Evolution

05-02-2015

▌ OEM and Tier One suppliers continually improve their systems, especially in relation to

repair and maintenance.

▌ Examples:

▌ 2nd generation radar sensors with much less sensibility due to the assembly

processes

▌ Auto-calibration, e.g. bi-ocular systems in premium models

▌ Autonomous sensor technology (MEMS)

*MEMS: Micro-Electro-Mechanical-Systems


Perspective

KNOWLEDGE

05-02-2015

▌ Active knowledge management

▌ Cost-effective training structures

▌ Marked by training in the company work process (reduces

the training period),

▌ Combination of training and ‘training on the job‘

▌ More expert knowledge


Perspective

Tools

05-02-2015

▌ Simplification of Tools and Processes = Mastering the Technology


Perspective

Networking / Big Data

05-02-2015

▌ Technological evolution

▌ Tools and processes

▌ Knowledge in the repair shop and experts

▌ Collecting, analyzing, combining and providing knowledge

right in time, right in place

‘cloud’ networking


▌ Why is calibration necessary?

▌ When is a calibration necessary ?

▌ What happens during a calibration ?

▌ How to do a calibration ?

Calibration

Example: Front Camera

05-02-2015


▌ The consequences of incorrect calibration demonstrated on an adaptive light system

Why is calibration necessary?


Calibration - correct Calibration – incorrect (glare)

05-02-2015


▌ After windshield replacement

▌ After accident damages

▌ After changes to suspension / suspension control / wheel alignments

▌ Wheel alignment during which toe/camber on rear axle were altered

▌ Modifications to the suspension affecting body height

▌ Re-initialization of height sensors in vehicles with Electronic Damper Control

▌ After replacement of the camera sensors, their carriers, or involved ECUs

▌ After changes at the chassis

▌ After relevant trouble code occurs

▌ e.g. „basic setting/adaption missing or incorrect“

▌ LIABILITY: Always according to manufacturer specifications!

When is calibration necessary?


05-02-2015


▌ Adaptation of the coordinate systems and scaling of sensor/arithmetical unit and

current vehicle geometry to the coordinate system of the environment .

What happens during calibration?

Front Camera Calibration

HGS process in 5 steps

▌ 5 steps easy-to-use camera calibration procedure

1. Adjust the distance

2. Centric & parallel

3. Adjust the panel

4. measure

5. start calibration


Summary


05-02-2015

▌ ADAS are essential !

▌ Trend: Number and functionalities are hugh increasing/improving

▌ Next big milestone: Autonomous driving !

▌ Biggest challenge: Master the complexity.

▌ Possible Solutions

▌ Technological Evolution

▌ Simplification of tools and processes = Mastering the technology

▌ Knowledge and Education

▌ Networking and Big Data

▌ … and suitable tools are available !

Thank you for

your attention.
