For dialog-based configuration of bypass applications and real-time ECU access.
Highlights:
- Selection of ECU variables from ASAP2 files
- Support of all major ECU interfaces such as CCP, XCP (CAN, Ethernet, FlexRay), on-chip debug ports and DPMEM PODs
- Automatic conversion between physical and hex representation
- Configurable failure checking and data consistency mechanism
Application Areas
For developing ECU functions by means of the external bypass approach, it is usually necessary to configure the bypass interface in the modelling environment and to change the input and output signals of the bypass model without ECU code modifications. The RTI Bypass Blockset provides a generic user interface for this purpose, with the same look and feel no matter what ECU interface is actually used for bypassing. The Blockset allows flexible selection of functions to be bypassed in the ECU code (bypass hooks) and variables to be transferred without changing the ECU code itself. In addition, with ECU testing and hardware-in-the-loop simulation, ECU-internal data are captured in real-time for validation purposes or for controlling test sequences.
Key Benefits
The RTI Bypass Blockset allows you to use dedicated Simulink blocks and user interfaces to set up the bypass application in the modelling environment. ECU-specific information, such as on the bypass interface, the bypass hooks implemented in the ECU code and the available variables, is automatically adopted from the ECU description file (ASAP2 file) and control engineers can fully concentrate on function design. The blockset allows you to select model inputs and outputs flexibly without ECU code modification. A variety of ECU interfaces are supported such as CCP, XCP on CAN, XCP on Ethernet (UDP/IP), XCP on FlexRay, the DCI-GSI1 and DPMEM PODs. When you use the dSPACE calibration and bypassing service or the dSPACE XCP service, dedicated mechinisms are provided to monitor the bypass communication, detect errors and ensure consistent data transmission.
Import of ASAM-MCD 2MC Files
An ASAM-MCD 2MC (ASAP2) variable description file can be easily imported as a database. An intuitive variable browser facilitates the handling of large description files by search options and hierarchical representation of variables. The variable names are mapped to the respective addresses on the ECU. The blockset allows you to access ECU variables via their names and automatically performs conversion between ECU hex and the physical representation on the dSPACE system.
