CANape is a software tool from Vector Informatik. This development software, widely used by OEMs and ECU suppliers of automotive industries[1] [2] [3] [4] [5] [6] [7] is used to calibrate algorithms in ECUs at runtime.

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. 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, LIN, Ethernet/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

All functions required to modify parameter values are implemented as standard features in CANape: Measuring, analyzing (manually or automated),[7] 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.[2] Options extend the functional features of CANape[8] 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.

Versions

Version 1.0 was released in 1996.[9] Up to Version 6.0 the product was known as CANape Graph. The latest version of CANape is 14.0[10] (revision level: June 2015).

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[1] and XCP on FlexRay.[2]

Supported ASAM standards,[11] status as of June 2015:

Other supported standards:

If a development task requires a high measurement data throughput of up to 30 MByte/s, Vector’s VX1000 System[3] can be used to access data over microcontroller-specific data trace and debug interfaces like JTAG, DAP, LFAST, RTP/DMM, Nexus AUX or AURORA.
