Hey STEEMIANS, if your reading this you probably opened this video so thanks for showing interest in my video. So this will be my first video after my introduction. Ive just messed with the premier pro but didnt do much as well. But for the sake of the video Ive mentioned everything that needs to be known about ABS.
MY FULL SCRIPT HERE:
So as its clear what it does, let’s get to know how does it work? Well there are three major components for any traditional abs to function. The first one would be
Wheel sensors- The only aim of these sensors is to monitor the speed of the individual wheel and send them back to the ECU which is the next thing we will be looking into.
ECU- well, an ECU is an electronic Control unit which is basically a computer chip built with algorithms to understand the data being received from these wheel sensors constantly and under programmed situations ECU unit comes into action by intervening with the user’s input towards the brakes via the pumps and valves to ensure safe braking is accomplished. Generally these ECU’s can predict the odds of wheel locking in a blink of an eye with successive predictions every 1\10th of a second.
Pumps and valves- Pumps and valves are controlled by the ECU when it needs to control the braking pressure. This can be done by closing the valves on and off in a rapid succession in a very short period of time which can prevent the wheels from locking up which is why we use the abs in the first place
Now let’s imagine an ABS equipped motorcycle rider riding at speed of 60kph enters a panic braking situation. He tends to apply full pressure on the brakes including the front and rear. When this happens the weight transfers towards the front of the motorcycle decreasing the traction available for the rear tire which eventually will lock and causes the rider to lose control due to skid which also increases the stopping distances. At this point the wheel sensors observe a steady steep in the speed of the rear wheel which tend to occur within a short span of time which is practically isn’t ideal for a safe braking condition which is where the ECU understand a Wheel has been locked. At this stage the brake fluid from master cylinder is intervened with these electronically controlled valves where they go on and off in a rapid succession as programmed in the algorithm of the ECU for that given scenario which will balance the weight transfer and help in regaining the traction by eliminating the lock up! This is usually done in a very short period of time hence can be effective.
The same mechanism is used for the front wheel as well but with a slight variation on how it is applied. There is an added benefit to the abs which is rear wheel lift off protection or RLP which means the rear wheel won’t be able to lift off due to harsh braking on the front wheel which is an added bonus to the already better abs safety !
Now as we have seen how abs works there are motorcycles which come with single channel abs and dual channel abs as well. Which basically means that in a single channel only the front wheel is the effective one and in a dual channel abs both the wheels are monitored and effective.
This is how a traditional abs works well there are other advanced and complex version of abs which is called cornering ABS. When we are riding a vehicle at straight line the contact between the tire thread and road surface is maximum but when the bike is leaned over to take a corner the contact between the tire and road surface decreases with the increase in angle. At this point even a slight braking mishap can lead to a complete loss of traction which can cause the rear tire to slide out of the line of travel dragging the front of the bike as well. A traditional ABS can make the braking easier without losing traction but as the braking occurs the lean angle tend to be minimized causing the bike to come to a stop out of the actual line of travel. To overcome this Cornering ABS uses different types of sensors like pitch angle, lean angle, roll rate, engine torque, longitude and vertical acceleration all are considered to help the rider entering a corner at high speed maintain the line of travel consistent while braking without losing the traction.
