How many times have we heard of a car accident wherein the driver lost control upon suddenly braking? Such accidents happen because during sudden breaks, the wheels stop rotating and the car starts to skid. This becomes even more dangerous on slippery surfaces as the car would only stop when it rams into a bigger object. You might ask: “these accidents have been happening for a very long time. Haven’t car manufacturers developed something to prevent this?”
Stop right there!
Ever heard of an anti-lock brake (ALB)? The anti-lock brake is a safety feature installed on motor vehicles that basically help prevent the vehicle from skidding upon sudden brake. At the same time, it allows the driver to still have control of the vehicle on sudden break scenarios. The brakes are timed to lock the wheels on short intervals instead of one full long break, thereby allowing the wheel to keep on spinning and, at the same time, slowing it down. This safety feature is very helpful especially on slippery and loose surfaces such as rocky roads on mountain trips.
Sounds great right? There’s more.
More advanced anti-lock brakes can even determine if your tires have deflated to the point that they need to be inflated again. What this system would do is to look at the spinning rate of the wheel during brakes. When one of the wheels is spinning faster than the others, then that could be a sign that one of the tires is already flat. Flat wheels have a higher average spin rate than inflated wheels. Now, you have two safety features on check with one anti-lock brake system: the brake and the tire inflation level.
