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 the ECU’s standard interfaces (CAN, FlexRay, LIN, Ethernet) via proprietary hardware interfaces. 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, calibrating, administering, evaluating, 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[7] by enabling access to models at runtime in Simulink, functional bypassing, optical verification of object detection algorithms in developing driver assistance systems, visualization of a vehicle’s GPS position and an ASAM MCD3 interface.

Versions

Version 1.0 was released in 1996.[8] Up to Version 6.0 the product was known as CANape Graph. The latest version of CANape is 13.0[9] (revision level: August 2014).

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,[10] status as of April 2010:

  • AE MCD-1 XCP
  • XCP on CAN Interface Reference
  • XCP on Ethernet Interface Reference
  • XCP on FlexRay Interface Reference
  • XCP on SxI Interface Reference
  • XCP on USB Interface Reference
  • AE MCD-1 CCP
  • AE MCD-2MC ASAP2/A2L
  • AE MCD-2D ODX
  • AE MCD-2 FIBEX
  • AE MCD-3
  • COM/DCOM Interface Reference
  • ASAP3 (Automation/Optimization Interface)
  • MDF

Other supported standards:

  • KWP2000 on K-Line
  • ISO 14230 (KWP2000 on CAN) and ISO 14229 (UDS)
  • CAN with DBC description format
  • FlexRay Communications System Specification
  • LIN
  • MOST

If a development task requires a high measurement data throughput of up to 5MByte/s, Vector’s VX1000 System[3] can be used to access data over microcontroller-specific data trace and debug interfaces.
