The micro-electromechanical system (MEMS) based sensor delivers improved performance, system integration, and total cost optimisation and has been designed for various automotive applications, including autonomous driving (AD), advanced driver-assistance systems (ADAS), inertial navigation, vehicle stability control, and camera or headlight alignment.
With the increasing push for vehicle autonomy and safety, there is a growing demand for extremely accurate sensors with comprehensive built-in safety features and a high level of integration.
Likewise, complying with technical regulations like the UNECE’s headlight levelling regulation requires accurate and cost-optimised solutions.
The SCH1633-D01 is a single-package solution optimised for zonal architecture where all required subsystems, like GNSS integration, chassis control, and vehicle attitude sensing (camera and headlight alignment) can utilise its measurements. It is targeted for deployment in the central vehicle inertia measuring unit (IMU) providing a high-quality signal for all subsystems within the vehicle even in the toughest environments. This integration helps to reduce system complexity and provides a much-needed opportunity for cost optimisation.
The SCH1633-D01 is packaged in a 24-pin SOIC housing and uses the SafeSPI 2.0 interface with an up to 20-bit data frame for a smooth and high-resolution output. The component supports various system-level time synchronization features, ensuring that the SCH1633-D01’s output can be easily harnessed across the entire vehicle. Furthermore, the extensive self-diagnostics features utilize over 200 monitoring signals to ensure the output is always trustworthy.
The SCH1633-D01 is designed to provide a high-quality output, even in harsh temperature conditions. It features AEC-Q100 grade 1 qualification to guarantee reliable use throughout the whole component lifetime and is ISO26262 compliant with ASIL-B+ rating (up to ASIL-D via system integration) for exceptional built-in safety.
Preliminary samples are available now. Mass production of this new solution is planned for early 2025.
