FIELD OF THE INVENTION

The present disclosure relates to methods and apparatus for controlling an electric motor.

BACKGROUND

Electric motors may be controlled using a vehicle control unit sending instructions to a motor controller. The motor controller may comprise a motor control algorithm to control operation of the electric motor via an inverter coupled to a power supply. The output of the motor controller may be based on the instructions received from the vehicle control unit. In use, current operating conditions may affect how the electric motor responds to these instructions. How the electric motor responds to the instructions may affect how resources are used and/or affect drive feel, and if not managed carefully may lead to damage of the motor, the motor controller and/or the power supply. For example, if the current drawn by the electric motor is too high the electric motor, the motor controller and/or the power supply may be damaged.

SUMMARY

Aspects of the invention are as set out in the independent claims and optional features are set out in the dependent claims. Aspects of the invention may be provided in conjunction with each other and features of one aspect may be applied to other aspects.
