What is Automotive: Definition and 120 Discussions

The automotive industry comprises a wide range of companies and organizations involved in the design, development, manufacturing, marketing, and selling of motor vehicles. It is one of the world's largest industries by revenue. The automotive industry does not include industries dedicated to the maintenance of automobiles following delivery to the end-user, such as automobile repair shops and motor fuel filling stations.
The word automotive comes from the Greek autos (self), and Latin motivus (of motion), referring to any form of self-powered vehicle. This term, as proposed by Elmer Sperry
(1860-1930), first came into use with reference to automobiles in 1898.

    Automotive Requesting Information on Automotive Diffusers & Downforce

    I’m in a conundrum. I’m trying to reflect the diffuser aspects of a formula one car for a computer game. The game requires that I indicate the x-y-z coordinates which would represent a central location of the force that a diffuser system creates. Now, I’m absolutely not an engineer, so I have...

    Automotive electrical contacts

    Hi, I had auto lights failing and instead of let the mechanics supply me with a brand new switch unit at a great rate, I delved into the switch unit to see what was happening. I noticed a lot of oil and grease in the box containing the switches. The contact plates were covered in the grease...

    Automotive Automotive Physics: Turning Radius & Rear Tire Force

    Hi everyone ^ ^ I was recently looking into the calculation to discover the turning radius of a vehicle and something peaked my interest about the way rear tires turn. I know it is common sense to just take for granted that in most FR cars these days, power is delivered to a differential...

    Solving for Average Acceleration: An Automotive Example

    was wondering which formula I would use to solve this equation... a car traveling in a straight line has a velocity of +5.0m/s at some instant. After 4.0seconds, it velocity is +8.0m/s. What is it average acceleration in this time interval?

    Automotive Automotive suspension systems: Curves

    If you wish to negotiate a curve while traveling at high speed, the largest radius should be followed through the curve in order to minimize the lateral forces acting on the car. However, in practice it doesn't really work this way. I have long noted that the car can actually be more stable...

    Automotive Can sensors on a car measure deceleration for a predictive braking system?

    I've got an idea for a predictive type of braking system. The general theory is great, however I am not a Mechanical Engineer at all ... just an idea incubator :-p Anyway ... my idea requires the use of deceleration of the vehicle. Are there typically sensors already on the car that...
