AUTOMOTIVE ELECTRONICS
emergency braking and collision detection depend on precise, low-latency data processing to assess the vehicle’s surroundings and react within milliseconds. ASICs play a critical role in this process, data to ensure split-second responses. Their role is to process radar and camera inputs, detect obstacles or sudden road changes and relay critical data to the vehicle’s control system, which then determines the necessary braking force to prevent a collision.
Beyond improving vehicle safety, ASICs play particularly in electric and hybrid vehicles where they support power distribution between the battery, motor and auxiliary systems.
By optimising energy transitions and enhancing regenerative braking, ASICs can improve energy capture and conversion lowers operational costs, making EVs and effective.
Advancing safety
As of July 2024, technologies such as advanced driver assistance systems (ADAS) and collision avoidance have been mandated for new motor vehicles sold in the EU and UK to improve safety for drivers and other road users.
ADAS features such as automatic
In BMS, ASICs can monitor individual battery cells’ state of charge, health and temperature, optimising charging cycles and ensuring safe operation. For TPMS, they process sensor data to maintain accurate tyre pressure readings, which enhances safety and reduces rolling resistance, If we look at internal combustion engine (ICE) vehicles, ASICs contribute to engine control units (ECUs) by processing data from exhaust sensors, fuel injectors and combustion systems. They help optimise fuel consumption, reduce emissions and enhance overall engine performance by enabling precise control of fuel injection, ignition timing and exhaust management.
Enabling intelligence
The reality of autonomous vehicles depends on sensor fusion- the ability to combine data from a variety of sensors to create real-time environmental maps for navigation and decision-making. Because ASICs can process vast amounts of sensor data with minimal latency, they generate precise 3D representations. This capability enables autonomous vehicles to accurately detect pedestrians, obstacles and other vehicles, enhancing navigation and safety.
Beyond object detection, ASICs enable real-time path planning, allowing vehicles to predict movement, classify objects and respond instantly to changing road conditions. They also support vehicle-to- everything (V2X) communication, enabling seamless data exchange with other vehicles and infrastructure for improved coordination.
Swindon provides a full turnkey service that optimises ASICs for automotive applications, overseeing every step from design to manufacturing and testing. This approach also ensures compliance with stringent industry standards, including ISO 26262 for functional safety and AEC- Q100 for quality. By tailoring ASICs to the intelligence.
As the automotive industry continues to evolve, ASICs play a crucial role in driving innovation. By enabling real-time data enhancing driver assistance systems, these custom chips are helping shape the future vehicles.
