CANape 10.0 - Option Bypassing

Bypassing Computation with Deterministic Time Behavior

A complete bypassing solution is available to you by interlinking CANape, VN8900 and the VX1000 measurement and calibration hardware. The VN8900 network interface serves as the computational platform here, and the VX1000 System assures a high-performance measurement and calibration connection to the ECU. In CANape, the overall solution is configured, and the signals and parameters are visualized.

Overview of Advantages

• Deterministic time behavior in computing the bypass function
• VN8900 network interface with integrated real-time computer serves as an execution platform for the bypass algorithm
• Seamless configuration of the bypass for VN8900
• CANape offers visualization of the bypass model and the ECU model with access to measurement data and parameters

Functions

In the Simulink model, you define your function and place CANape I/O function blocks at the model's inputs and outputs. After code generation, compiling and linking, a DLL is available in CANape for integration.
In CANape, the model's inputs and outputs are linked to the real signals from the ECU. The bypassing algorithm is automatically transferred from CANape to the VN8900 by a configuration change that is easy to execute. This transfer loads all relevant data and configurations into the VN8900. At model runtime on the VN8900, you acquire the necessary input data from the ECU via the VX1000 hardware. This enables measurement data rates that are over one hundred times faster than with CAN. In turn, the algorithm results are sent to the ECU over XCP on Ethernet and the VX1000 hardware. Using CANape, you can then measure and calibrate the bypass algorithm on the VN8900 and the code in the ECU.
