AI Technical Summary

Technical Problem

Existing systems prematurely shut down motor functions due to fixed voltage limits, leading to reduced availability and inability to meet torque demands, especially in energy-efficient vehicles.

Method used

Determine the maximum possible torque output of the motor and use it to assess availability, adjusting current control to meet desired torque requirements without changing supply voltage, and predict future torque capabilities using a characteristic map.

Benefits of technology

Enhances motor availability by preventing premature shutdowns and ensuring functions are only deactivated when necessary, optimizing energy use and maintaining functionality.
