The active safety features are predominantly the features that work to prevent or lower the risk of a collision occurring. They are so named because they are always active, and working to try and prevent an accident. Whereas passive Safety Features are systems that are passive up until called into action. They only become active during the accident and aim to help minimize the damage from the collision
Generally, active safety systems can keep working and resetting themselves over and over again, whereas once the passive safety features have deployed, they are no longer functioning and would need to be replaced.
To understand and develop active safety systems you need to consider, the available sensors and technological systems that can be fitted to a vehicle in order to allow it to actively avoid, or minimize the risk of a collision occurring.
These active safety features are often referred to as ADAS – Advanced Driver Assistance Systems.
Advanced Simtech can provide your organization with support and services to help either understand the influence of an existing active safety feature or to develop a new capability.
We have been working with ADAS and active safety systems for over 8 years, providing support and assistance to our customers, helping them to develop and validate their products.
Our unique position within this sector allows us to assist with both Virtual testing for development as well as transferring real-world test data back into the virtual world to fine-tune and improve the performance of your chosen system.
2) Driver Warning – The ability to alert the driver of any hazards (Head up display, driver drowsiness, parking sensors)
3) Collision Avoidance – by understanding its position relative to others cars and road users it can avoid any potential collisions. (, Braking Assist, Front and surround sensors such as radars and lidars)
4) Collision Mitigation – If the crash is going to happen, it can help to minimise the energy or level of impact.( automatic emergency braking, steering away, electic seatbelt retractors pull in the webbing to restrain occupants)
5) Injury Mitigation – standard passive safety features operate in the event of a collision (airbags, pretensioners, seatbelts as the vehicles crash structure is loaded and crumples under impact)
6) Post Crash – information automatically transmitted to the emergency services or the interior occupants. (providing the vehicles location and number of occupants, along with crash severity and impact direction. Fire suppression systems and high voltage circuit breakers to disconnect the battery in an electric vehicle).
The Society of Automotive Engineering (SAE) has developed a guideline on Autonomous driving, dividing the technology into 5 clear levels.
Driven by the vision of accident-free and autonomous driving, ADAS and highly automated driving functions offer great potential for innovation in the automotive industry (and beyond).
However, while the systems become increasingly complex, the development and validation efforts have to stay manageable.
In order to develop a robust solution to any automotive problem, engineers have to combine the fields of virtual development and testing together with physical validation. Advanced Simtech is in a unique position to assist customers in their development of ADAS and autonomy functionality through their partnership with leading industry experts and products.
We are the distributors of the Simcenter Prescan software in the UK and Ireland with dedicated support and presales to help your organization.
We are also the UK and Ireland distributor for IBEO Automotive, proving sales and support for their unique range of vehicle lidar products together with their innovative software toolsets.
The future of Occupant Safety
The trend towards higher levels of fully and highly-autonomous driving also has the potential to allow new degrees of freedom for vehicle users performing non-driving functions, such as conversing with other occupants in newly configured, more convenient seating positions. This, of course, presents a whole new paradigm shift for the problem of occupant safety which today is based stringently on regulations for occupants in (fixed and defined) seating positions.
The major part of the validation and verification (V&V) of such AV systems cannot be achieved through semi-virtual or real-world physical validation alone. Therefore, frontloaded virtual V&V at MiL (Model in the Loop) and SiL (Software in the Loop) stages will have to play a much bigger role in any development process.
The development of AV systems requires efficient and fully automated simulation orchestration to help engineers in developing their ADAS systems. Hence this is why Advanced Simtech works together with our key partners to provide an efficient and cost-effective workflow and proven toolset.
Linking Virtual testing with real-world driving is essential to develop robust and reliable AV systems.
