Capacitive sensors for automotive safety

In late July, the Automotive Safety Summit Shanghai focused on safety technologies for smart, autonomous and electric mobility of the future. With innovative sensor solutions ‘Made in Germany’, ASC is leading the way.

Safely into the future

Since 2014, the Automotive Safety Summit Shanghai – organized by knowledge transfer and training specialist Carhs – attracts more than 300 automotive safety experts annually from China and beyond to discuss the latest requirements and innovations in active and passive safety. Accompanied by a comprehensive trade exhibition with global vendors of development technologies and services, the summit is a leading event for everyone involved in automotive safety.

The 2023 event focused on automotive safety in the context of current megatrends: new electronic vehicles (NEV), advanced driver assistance systems (ADAS) and autonomous driving systems (ADS). ASC was represented at the summit by the General Manager of its China sales office, Jason Ji. He introduced the company’s long-standing expertise in designing customized sensor solutions, its range of high-precision accelerometers and sample applications in automotive safety.

Real time data processing

In fatigue strength tests and test drives, for instance, ASC’s MEMS based accelerometers ensure the precise, reliable, interference-free data collection with no signal loss. Their excellent temperature resistance and long-term stability allow for the reproducibility of results during long testing periods even under varying environmental conditions.

Uniaxial and triaxial gyroscopes from ASC are frequently used in Advanced Driver Assistance Systems. Their excellent response behavior leads to minimal latency, which means they can process vehicle data and driving situations in real time. This allows for generating immediate feedback to the driver or the direct intervention in the vehicle’s operation in case of emergency.

Sensors for e-mobility

ASC’s modular IMU concept offers hundreds of configuration options to support e-vehicle and component manufacturers in testing and optimizing their products. In this, flexible yet highly robust and accurate sensor solutions are essential as electric vehicles differ materially from combustion engine operate ones; not least in their weight, center of gravity, acceleration and deceleration behaviors, all of which have a significant impact on driving dynamics and drive comfort.

In e-mobility, ASC sensors further play an instrumental role in the safety testing to certify high-voltage batteries. As prior to a new battery’s installation, it has to meet rigorous national and international norms. For example, the range of shock resistance may vary between 20-120 ms and 2-40 g depending on country and registration authority involved; likewise, an e-vehicle battery must be able to resist vibrations from 7-50 Hz and 2-10 m/s2. To meet the various standards paired with the complex needs of a diverse range of car and battery manufacturers and their suppliers, while precisely capturing all relevant technical parameters, sensors of broad operating range are required.

Quality ’Made in Germany‘

These are but a few of the ASC sensor applications introduced by Jason Ji at the Automotive Safety Summit Shanghai end of July. “Our industry experts value quality ‘Made in Germany’’,” he reports. “In the minds of most Chinese, this translates to high precision, high quality and long-term stability.”

“At ASC we’re working hard to match high-quality customized solutions with competitive pricing.” So that more and more clients may benefit from ASC’s proverbial German quality.
