L0

Driver Only

There are 6 levels of autonomous driving, between no automation (L0) up to full control by system (L5)

L1 L4 L5 L2 L3 Humans always monitor driving functions Humans do not always monitor driving functions

Driving Assistance High Automation System Only Partial Automation Conditioned Automation

Role of driver Role of system None Driver always with full control Some automation by electronics Driver always in charge of monitoring Driving assis- tance in specific and limited situations Driver needs to be ready to regain control Perform driving functions and recognize limits Driver only needs to act in specific driving conditions Full control in defined driving conditions No driver needed Full control Eyes + hands on Eyes on + hands temporary off Eyes + hands temporary off Eyes + hands off Eyes + hands + mind off

All of today‘s potential sensor solutions for ADAS have specific strengths and weaknesses; hence all are needed to guarantee full functionality

LIDAR Camera Radar

Surround view Surround view Environment Mapping Environment Mapping Environment Mapping Environment Mapping Environment Mapping Surround view Traffic Sign recognition Lane departure warning Emergengy braking Pedestrian detection Collision avoidance Environment mapping

Value propositions of different technologies (selection) Camera Color vision and ability to recognise signs Radar Speed detection and ability to function in unfavorable weather conditions / darkness LiDAR 3D capability and ability to function in unfavorable weather conditions / darkness

  • The vehicles ability to ‚see‘ (= sense its environment)

strongly depends on the environmental conditions, such as day time or weather

  • Full functionality at any environmental condition therefore

requires different and redundant sensors

  • In addition, redundancy is being generated using intelligent

algorithms (sensor fusion)

Cross traffic alert Blind spot detection Rear collision warning

  • Only the combination of all three systems will provide all technical capabilities needed for autonomous driving

LiDAR will be required for autonomous driving; 6 or more LiDAR modules for L4/L5

  • Co-existence of LIDAR, RADAR and

camera sensors in Autonomous Driving (L3 upwards)

  • LIDAR crucial for long-range detection

in AD, no different substitute technology available, specifically for object identification

  • Six or more LiDAR modules expected

for L4/L5 LiDAR will play a key role in autonomous driving (especially L3 upwards)

MaaS - Mobility as a Service path (e.g. waymo)

Two different approaches to autonomous driving: Mobility providers starting with L5 short term, traditional OEMs evolve from L1 to L5

L3 L5

  • Two completely different approaches to

autonomous driving with different dynamics driven by two distinct groups of players – mobility-as-a-Service providers (MaaS) and traditional car manufacturers

  • MaaS providers pushing for early

introduction of fully autonomous vehicles today in significant numbers

  • Traditional car manufacturers

moving to L3; introduction of fully autonomous cars expected for 2024+

  • However, in the long run there will likely be a

convergence of the two approaches ILLUSTRATIVE

LiDAR uses reflected light to measure distance to objects; it can be used for short-range up to a distance of ~300m

Detection principle: A very short laser pulse travels from the LiDAR sensor to an object and

  • back. The sensor measures the

travelling time of the laser pulse and determines the distance and relative velocity of the object. 100 m distance  0,6 ms LiDAR (Light Detection and Ranging) – a Time of Flight measurement

the field of view and the signal captured by the detector

  • The signal is then processed by the

ASIC1 and forwarded to the processing unit

There are two basic LiDAR technical implementations – flash and scanning LiDAR

Scanning LiDAR Flash LiDAR

  • The whole FOV is illuminated at once using a

wide-angle beam

  • No moving parts in the LiDAR module
  • Scanning, narrow emitter beam which is being moved

across the FOV over time

  • Mechanical solution or micro-mirrors used for beam steering

EMITTER EMITTER

  • High to very high

power needed to illuminate the whole scene with one laser beam

  • In the future, laser

bars (edge emitting laser) with high power for longer distances or potential use of VCSEL for SRL

  • Highly directional

beam with high power needed

  • Good thermal

performance for high repetition rate

  • Today and in

future edge emitting lasers

  • perating at

905nm expected to dominate

Laser technology VCSEL Comparison of basic laser technology and wavelength Fit to LiDAR requirements

  • Light emitted from surface
  • f laser die

Component cost

  • Temp. stability1)

Conclusion Output power Efficiency Potential use for short range LiDAR Eye safety Technology too expensive Best overall fit to requirements

  • In most cases, edge

emitting laser @905nm expected to be the winning technology

  • 1550nm with better eye

safety, but otherwise lagging behind and too expensive for customer requirements

  • VCSEL potentially

useful for short range LiDAR, but yet to be automotive qualified Edge emitting laser

  • Light emitted from a small area in the side of the laser die

<1000nm2) Emitting area >1000nm typically <1000nm

  • Strong position in

emitter lasers

  • Evaluating portfolio

fit of detectors

  • Signal processing

OSRAM is well positioned to participate in the LiDAR market

Next to our strong position in emitter lasers for LiDAR systems, we are evaluating to extend our portfolio in the area of detector components and smart modules, concentrating on the essentials of data fusion:

  • working closely together with LeddarTech in order to assess the industrialization of LiDAR modules for the automotive mass market.

Specific focus is on affordable long-range LiDAR modules

  • acquired a strategic stake in the LiDAR start-up company Blickfeld. Its particular strengths lie in beam steering technology, which

permits a full scanning of the surrounding environment

  • smaller, purely financial investment in the start-up company Tetravue, which uses a unique approach for high-resolution depth images
  • Optics and beam

control

  • High resolution

depth images

  • Additional

application fields beyond automotive
