Speed (rad/s)
Q3:
Redo Q1 using the UDDS drive profile. Note the considerably lower oper-
ating torque levels.
A3:
The operating points for a UDDS cycle are well inside the MG1 torque-
speed envelope shown for Q1. This is because the UDDS is a moderate drive
schedule in comparison to the US06, an aggressive drive schedule.
Q4:
Redo Q2 using the UDDS drive profile. Again, note the much lower oper-
ating torque levels corresponding to this more benign drive schedule.
A2:
The operating points for a UDDS cycle are well inside the MG2 torque-
speed envelope shown for Q2. For the same reasons as stated in A3.
