The automotive industry faces a significant challenge in the validation process, wherein engineers must physically visit vehicles to test and simulate faults from previous software iterations. These faults are then replicated in updated software to assess rectifications. The discussed process entails turning on the ignition, cranking the vehicle, performing brake presses, using the shifter for input commands, and scrutinizing Instrument Panel Cluster outputs while observing CAN signals graphically to evaluate Electronic Control Unit (ECU) functionality. This manual approach is time-consuming and often hindered by vehicle availability, necessitating a shift towards bench-level testing. This paper introduces a model that demonstrates vehicle functionality using panel design and CAPL (Communication Access Programming Language) within the CANoe environment. The model encompasses gear engagement and disengagement, vehicle speed variations, and various engine states. By utilizing bench-level testing and simulation techniques, engineers can efficiently evaluate software updates, identify faults, and verify ECU functionality without relying on physical vehicle access. This approach not only streamlines the validation process but also enhances accuracy and control in software modification assessments.

摘要

The automotive industry faces a significant challenge in the validation process, wherein engineers must physically visit vehicles to test and simulate faults from previous software iterations. These faults are then replicated in updated software to assess rectifications. The discussed process entails turning on the ignition, cranking the vehicle, performing brake presses, using the shifter for input commands, and scrutinizing Instrument Panel Cluster outputs while observing CAN signals graphically to evaluate Electronic Control Unit (ECU) functionality. This manual approach is time-consuming and often hindered by vehicle availability, necessitating a shift towards bench-level testing. This paper introduces a model that demonstrates vehicle functionality using panel design and CAPL (Communication Access Programming Language) within the CANoe environment. The model encompasses gear engagement and disengagement, vehicle speed variations, and various engine states. By utilizing bench-level testing and simulation techniques, engineers can efficiently evaluate software updates, identify faults, and verify ECU functionality without relying on physical vehicle access. This approach not only streamlines the validation process but also enhances accuracy and control in software modification assessments.
