Speed based foldback Powermap

The requested motor torque, torque reference, can be scaled back from the available current based on the current motor speed over various speed ranges.

Setup

• The slopes between each Power map Watts setpoint parameters (157-164) value are calculated, along with offsets corresponding to the start of the range
• The current vehicle speed is compared to the speed limit setting as a percentage, which maps between the Power map speed setpoint parameters (165-172).
• Based on which setpoints the current vehicle speed maps between, the corresponding slope and offset calculated initially are utilized to calculate the Foldback.
