Motorbike Traction Control System (TCS)

Few years back, this feature is most popular in four wheelers and now its becoming more popular also in motorbikes. We can able to see this feature mostly in high end models which helps to steer properly & efficiently especially over the slippery surfaces. This system helps in maintaining enough traction & grip to compromise both the stability and speed of the motorbike.

Motorbike Traction Control System (TCS)

In other words, we can say like this system prevents the motorbike from unnecessary drift by controlling the power which is delivered to the rear wheel thus controlling the rotational speed of the rear wheel. Generally, there are two types namely reactive and predictive. In the first type, corrections were made after the spinning of the wheel by various components. In the later one, various sensors feeds the ECM with signals and makes changes before the wheel starts to spin and it also continuously judge the probability and acts fast according to that.

For example, ECM along with different sensors monitors various parameters such as throttle position, gear position, vehicle speed and controls the traction of the vehicle thereby preventing unwanted slippage. Modern day ECUs monitors various different info like lean angle and gravitational force with the help of Inertial Measurement Units (IMU) and those collected data will be processed within a second. The basic idea here is to prevent the spinning of the rear wheel by cutting the engine power sent to the rear wheel.

Wheel Speed Sensor (WSS) in both the wheels always monitors its speed. If one wheel's speed becomes higher than that of the other's, then it'll become easy for us to lose the control of the motorbike. If sensors notices this, it acknowledges the ECM where it cuts the fuel supply to the engine which leads the engine to misfire thereby the power will not be produced by the engine momentarily. There's also another method which is done with the help of ride by wire system. With this system, valve's position in the throttle body is actuated electronically with the help of servo motor. Here, ECM electronically adjusts the throttle position by itself thereby cutting the power sent to the rear wheel. This happens until both the wheel's speed are matched with one another.

This system is very much useful for machines with more power. It plays a vital role in off-roading models. In tracks, each and every second is important for the rider especially at the exit of the corners where this system comes handy and also ensures the safety of the rider.
