CANape

CANape（キャナピー）はベクター・インフォマティックのソフトウェアツール。この開発ソフトウェアは、自動車業界のOEMおよびECUサプライヤーによって広く使用されており、動作中にECUのアルゴリズムを調整するために使用される。 ECUのキャリブレーションでは、さまざまな車両モデルやバリエーションの制御動作が変更される。プログラムコードを変更することなく、ECUのパラメータ設定を変更することによってこれを行う。このために、実験室、テストベンチ、または車両でのテスト試行でCANapeなどの測定・キャリブレーションシステムを利用することがある。パラメーターの変更の影響を評価するために、開発エンジニアはセンサとアクチュエータで従来の測定技術を使用して関連するプロセス変数にアクセスし、ECUからデータを読み取る。ECU内部の測定データ（例：計算関数の中間結果）は、ASAM標準プロトコルXCP（英語版）またはCCPおよびECUの標準インターフェース（(CAN、FlexRay、LIN（英語版）、Ethernet / BroadR-Reach（英語版））を介してアクセスできる。 For a high-performance ECU access, data from microcontroller-specific interfaces (for example JTAG, DAP, AURORA) can be converted via an external hardware (like Vector’s VX1000 system) in XCP on Ethernet. A typical use case for calibration with CANape is online calibration. This involves modifying parameters directly in the ECU. The resulting control characteristic can be measured and checked directly. Using this approach, measured data from the ECU or physical measurement variables on or in the vehicle can be precisely analyzed to determine the effects of each individual change. Functions required to modify parameter values are implemented as standard features in CANape: Measuring, analyzing (manually or automated), calibrating, calibration data management, and flashing. CANape also enables symbolic access to data and functions accessible via the diagnostic protocol, and it supports calibration over XCP（英語版） on FlexRay. Options extend the functional features of CANape by enabling access to models at runtime in Simulink, functional bypassing, optical verification of object detection algorithms in developing driver assistance systems (ADAS), and an ASAM MCD3 interface. CANape uses its own scripting language, hereinafter referred to as CASL (Calculation and Scripting Language). CASL, is a signal-oriented language. CANape contains a function editor for writing cross-device functions and scripts. The CASL scripting language used for this is similar to the C programming language. For easier use, CANape provides an IntelliSense input, code blocks, and various built-in function groups. Functions and scripts can be used to solve a variety of different tasks from simple calculations, e.g., adding signals, to automation of CANape. Version 1.0 was released in 1996. Up to Version 6.0 the product was known as CANape Graph. In January 2017, CANape version 15.0 was current. In October 2019, the current version was 17.0. Internal ECU parameters are accessed via standardized measurement and calibration protocols such as CCP (CAN Calibration Protocol) and XCP (Universal Measurement and Calibration Protocol). CANape was the first measurement and calibration tool to enable access over XCP on CAN and XCP on FlexRay.
