Motor Controller logic block diagram
Role of subsystem in vehicle
This block implements some of the logical control functions of the motor’s controller (a.k.a. inverter). It prevents the controller from requesting more current than it can handle, and shuts the motor off if the vehicle is not moving or if the gearbox is in the process of changing gears.
Description of modeling approach
To enforce the motor/controller’s current limit, the maximum requested power is computed as the product of the maximum current, mc_max_crrnt, and the bus voltage at the previous time step. This product is the limiting absolute value that the power request will take on: the motor/controller will ask to take no more power from nor give more power to the bus.
Boolean logic enforces the required off conditions.
