Texas Instruments today introduced a new integrated automotive chip that enables a safer, more immersive driving experience for drivers in vehicles at all price points.The TI AWRL6844 60GHz millimetre-wave radar sensor enables a safer driving environment with a single chip running edge AI algorithms that support occupancy detection for seat belt reminder systems, in-vehicle child detection and intrusion detection. driving environment. High-quality audio experiences are more affordable with TI's next-generation audio DSP cores, AM275x-Q1 MCUs and AM62D-Q1 processors. Combined with TI's new analogue products, including the TAS6754-Q1 Class D audio amplifier, engineers can achieve a complete audio amplification system solution. TI will showcase these devices at the Consumer Electronics Show (CES), January 7-10, 2025, in Las Vegas, Nevada.

‘Whether it's an entry-level or luxury car, fuel or electric, today's drivers expect these vehicles to deliver a better in-vehicle experience,’ said Amichai Ron, senior vice president of TI's Embedded Processing Division. ‘TI continues to deliver innovative technologies designed to drive the development and improvement of the future automotive driving experience. Our edge AI radar sensors help automakers improve vehicle safety and respond quickly to driver actions and needs, while our audio-on-a-chip systems enhance driving enjoyment by providing a more immersive audio experience. Together, they create a whole new in-vehicle experience.’

Three-in-one radar sensor with edge AI support improves detection accuracy

Original equipment manufacturers (OEMs) are increasingly integrating more sensor technologies into vehicle designs to enhance the in-vehicle experience and meet evolving safety standards. With TI's edge AI-enabled AWRL6844 60GHz millimetre-wave radar sensor, engineers are able to integrate three in-vehicle detection functions in lieu of multiple sensor technologies, such as seat weight sensing pads and ultrasonic sensors.

The AWRL6844 integrates four transmitters and four receivers to provide high-resolution detection data at a cost optimised for OEM use. The collected data feeds into application-specific AI-driven algorithms that run on customisable on-chip hardware accelerators and DSPs, enabling more accurate decision-making and faster data processing.The AWRL6844 sensor's Edge Intelligence capabilities help enhance the driving experience, for example:

While in motion, the sensor detects and locates occupants with 98 percent accuracy to support seat belt reminders.

When parked, it uses neural network technology to monitor the car for unattended children and detects small movements in the car in real time with over 90 per cent classification accuracy. This direct detection technology helps OEMs meet the Euro NCAP design requirements for 2025.

When the vehicle is parked, it adapts to different environments through intelligent scanning technology to reduce false alarms caused by body sway and external object movement.

TI's Complete Audio Portfolio for a Better Automotive Audio Experience

As driver expectations for the in-vehicle experience continue to rise across a wide range of vehicle types, OEMs are looking to minimise design complexity and system cost while delivering high-quality audio. the AM275x-Q1 MCU and AM62D-Q1 processor reduce the complexity and cost of designing an in-vehicle audio system by combining TI's vector-based C7x DSP cores, Arm® cores, memories, audio networking, and a hardware security module in a single SoC that meets functional safety requirements. The C7x core, combined with a matrix multiplication accelerator, forms a neural processing unit for processing both traditional audio algorithms and edge AI-based audio algorithms. These automotive audio SoCs are scalable, allowing designers to choose from entry-level to high-end systems based on varying memory and performance requirements, with minimal redesign and no significant investment.

TI's next-generation C7x DSP core delivers more than four times the processing performance of other audio DSPs, enabling audio engineers to simultaneously process more audio functions on a single processor core. the AM275x-Q1 MCU and AM62D-Q1 processor feature spatial audio, active noise cancellation, sound synthesis, and advanced in-vehicle networking capabilities including Ethernet audio-video bridging to enable an immersive audio experience inside the vehicle. immersive audio experience in the car.

To further optimise automotive audio designs, engineers can use TI's TAS6754-Q1 audio amplifiers, which feature innovative 1L modulation for superior audio performance and low power consumption, and require half the inductance compared to existing Class D amplifiers The TAS67xx-Q1 family of devices integrates real-time load diagnostics required by OEMs to help engineers simplify designs, reduce costs and lower costs. The TAS67xx-Q1 series integrates real-time load diagnostics required by OEMs to help engineers simplify their designs, reduce costs and improve efficiency while ensuring that audio quality is not compromised.
