Musk lays out designs, he tries to always utilize “first principles thinking.” Tesla design goes back to the basics at the beginning, starting from scratch. It is good to keep in mind during this discussion that when Mr.
(Note: Displays do have their own processor to put the images on the screen.) Then there are the secondary functions that are not vital for life safety - power windows, door locks, environmental controls, and displays showing vehicle status, navigation, entertainment, and so on. A few vital operations are a) keeping the battery pack happy, b) starting, steering and stopping, and c) operating the lights, wipers, turn signals, horn, etc. The computer simply cannot freeze up at 60 miles per hour! To help explain how this works, this is a multi-segment discussion of the “solid state” devices, including the central controlling CPU(s) and the supporting Firmware (instructions embedded in the CPU) and Software (instructions written to the computer that can be changed when desired) that make an EV possible.Īll of this central control is necessary and operates through commands and feedback from all the other solid-state devices to perform an EV’s operational functions.
Discrete transistor computer how to#
The EV computer (controlling the entire vehicle in the case of Tesla), the central processing unit (CPU) and the associated software/firmware that tells an EV’s solid-state devices how to operate, has to keep the EV running without fail. How do you restart a stalled electric vehicle (EV) using Microsoft software? You close and open the windows of course!īut this joke makes a point. The first step is to tell the mandatory joke about computer-controlled cars.
