Development tools for electric and hybrid drivetrains
Electric and hybrid drivetrains – Challenges and opportunities
The development of new drivetrain concepts is an important area of innovation for the future of the automobile. They offer the opportunity to gain market shares and develop new markets. Hybrid Electric Vehicle (HEV) and pure electric vehicles play a key role in this. The following challenges play a significantly important role in the development of ECUs in this segment:
Designing New Functions
Electric motors require high-speed control functions because the torque produced follows current directly. This means that time behavior has become more important in development, prototyping, and testing.
The development of new drives takes place in a dynamic environment with constantly changing requirements. This means that additional flexibility and easy extension of the development environment with specialist software of low complexity is growing in importance.
Isolating Measurement Probes
The ETAS isolating measurement probes are used to measure voltages on high voltage electrical systems used in hybrid or electric vehicles. The probes offer a high level of safety due to electrical isolation near the measuring point.
Especially for HEVs, overall systems are becoming far more complex. Many functions are distributed across an ECU network. In addition, there are more and more functions which operate across drive, transmission and brake system components.
Rapid Function Development
New functions for the electric drive train must be developed fast and reliably. This applies to individual components such as the closed-loop controlling of the electric motor, the battery and thermal management, but also for the common drive management of gearbox, electric motor and combustion engine with Start-Stop operation, recuperation and Power-Boost (hybrid management).
