自動運転向け高分解能GMRホイール速度および距離センサIC

A19360

A19360は、GMR技術、革新的なアルゴリズム、柔軟な出力プロトコルを活用することで高精度の信頼性が高いパフォーマンスを実現し、自動運転用途向けに高解像度の速度および距離データを提供します。

Enhances vehicle system information on wheel movement
Designed for SAE J3016^TM Levels of Driving Automation^TM 3, 4, and 5
Provides distance measurement capability with 5mm resolution (based on a typical 2m tire circumference and 48-pole pair encoder)
Patent-pending algorithms generate the high-resolution events with robustness
The four-event per magnetic cycle mode doubles the number of outputs per magnetic cycle (compared to a normal wheel speed sensor), enabling the use of ring magnets with half the number of poles for potential system cost reduction and increased air gap capability
The eight-event per magnetic cycle mode uses a special protocol that's compatible with AK protocol ECU hardware, paving the way for next-gen ADAS vehicle control
