I have a very limited knowledge on Automobiles. Now, Imagine a ICE car on a straight road at constant speed. Suppose the engine rpm is 1000. Suddenly the car has to climb a steep hill. Now the driver does not change the accelerator or the gear. The vehicle speed and engine rpm naturally lowers and inorder to increase speed one has to increase throttle.
Let's put this on an electric car. Do you have to hit accelerator to increase speed? Or the closed loop control of the motor automatically adjusts the motor rpm?
