22 Strategy Development Lab Answers Final speed is ~ 13 MPH. The interface uses physical units like C, MPH, Pascals. The brake_pedal, average_torque, and throttle_characteristics models are actual algorithms and are not S-functions. spark = base_spark spark_corr fuel_pulse_width = base_fuel_pulse * fuel_trim_factor Changing the shifter logic via the saturation block forced the simulation to always be in 1 st gear.

Virtualization has accuracy, visibility, controllability and repeatability. HIL simulation is hard real-time and a practical verification method. Full simulation is required and critical to today s designs. Simulation provides more efficient and controlled testing and verification. These technologies greatly reduce development effort and costs. These technologies offer better reliability with more confidence. These technologies are available now. Renesas pulls all of these technologies together with our partners into Velocity Lab. 37
