Description

In calibrating ECUs, control behavior is modified for different vehicle models or variants. This is not done by making changes to the program code, but instead by changing the ECU's

parameterization In mathematics, and more specifically in geometry, parametrization (or parameterization; also parameterisation, parametrisation) is the process of finding parametric equations of a curve, a surface, or, more generally, a manifold or a variety, d ...

. This involves the use of measurement and calibration systems such as CANape in the laboratory, on test benches or in vehicles during test trials. To evaluate the effects of changes to parameters, development engineers access the relevant process variables with conventional measurement technology at sensors and actuators and read out the data from the ECU. Measured data internal to the ECU, e.g. intermediate results of a computational function, can be accessed via ASAM standard protocols XCP or CCP and the ECU's standard interfaces ( CAN, FlexRay,

/ BroadR-Reach). 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.

Features

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 on FlexRay.

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.

Versions

Version 1.0 was released in 1996. Up to Version 6.0 the product was known as CANape Graph. In January 2017, CANape version 15.0Version History CANape

Supported Standards

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.
