BUP44 - BEV-FIT

The components of mechanical drive systems for electromobility are less complex than the mechanical systems of conventional drives and therefore in principle less susceptible to faults. At the same time, the challenge lies in the relatively limited experience in dealing with faults in the electric drivetrain and their impact on driving dynamics compared to conventional drives.

Aim

The components of mechanical drive systems for electromobility are less complex than the mechanical systems of conventional drives and therefore in principle less susceptible to faults. At the same time, the challenge lies in the relatively limited experience in dealing with faults in the electric drivetrain and their impact on driving dynamics compared to conventional drives.

Approach

• Use of fast simulation software specially designed for high-frequency processes in electrical systems to analyze the operating behavior of electrical and electronic components such as inverters and motors
• Coupling this high-frequency real-time simulation software for electrical systems with vehicle dynamics simulation software
• Injection of the real-time simulated fault cases into the demonstrator vehicle on the real test bench

Benefit

• Verified vehicle model of the demonstrator vehicle in the implemented simulation environment
• Possibility of investigating faults in the electric drivetrain on the real vehicle
• Verification of fault detection algorithms from previous ICM projects
• Early detection and reduction of safety risks that may arise due to the influence of faults on the vehicle's driving dynamics or controllability
