Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD)
The automotive industry is in the midst of a revolutionary change that is fundamentally modifying our understanding of driving. The players in this transformation are Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD). These technologies are designed to increase safety, optimize traffic flow and ultimately usher in a new era of driving.
Advanced Driver Assistance Systems (ADAS)
ADAS encompasses a variety of technologies that have been developed to make vehicles smarter and safer. These systems support the driver in everyday road traffic. These systems include:
Adaptive Cruise Control (ACC):
This technology automatically adjusts the speed of a vehicle to the traffic ahead. This not only increases driving comfort, but also reduces the risk of accidents. The vehicle decelerates according to the speed of the vehicle in front and accelerates automatically when the traffic speed increases. Speed limits are also recognized and the speed is automatically adjusted.
Lane-Keep Assistant:
The driver is warned if the vehicle unintentionally leaves the lane. Lane-keep assistant intervenes in the steering if the driver does not correct the lane shift. This helps to prevent accidents caused by distraction or fatigue.
Emergency Brake Assist:
Impending collisions are detected and automatic braking is initiated if the driver does not react in time. This prevents or at least mitigates serious accidents.
Autonomous Driving (AD)
Fully autonomous vehicles that can drive without human intervention are the pinnacle of development in the field of vehicle automation. A distinction is made between different levels of autonomy from AD Level 0 (no automation) to AD Level 5 (full automation).
Level 1 and 2 (partial automation):
Vehicles can partially take over certain tasks such as steering and braking, but still require the driver's attention and intervention.
Level 3 (conditional automation):
The vehicle can drive autonomously in certain situations, but the driver can take control in most cases.
Level 4 (high automation):
The car can perform most driving maneuvers autonomously, but there are certain situations where human intervention is required.
Level 5 (full automation):
The car can drive autonomously in any situation, without human intervention.
Requirements and Challenges for Measurement Systems
Although Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD) represent huge advances in automotive technology, there are still some challenges to overcome associated with the development and deployment of ADAS & AD.
Measurement technology plays a crucial role in the development, validation and implementation of Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD) as it helps to ensure the reliability and safety of these systems.
