ABS brakes require some additional dynamics in order to make them effective towards maintaining vehicle stability. The steering angle, speed and suspension levels all require being monitored closely to ensure the vehicle does not spin out of control while driving. Since this could be difficult for a driver to judge within a matter of seconds where collision is eminent, it would be too late. Therefore, Electronic stability control systems are the answer to this problem.
Several sensors are mounted to different parts of the vehicle to monitor the speed, pressure and levels of the vehicle. They are relayed back to an on-board computer (ECU). With the computer, the data has been entered in advance and the calculations made to determine the danger levels that could hypothetically result in the vehicle losing control. The sensors record and send the data to the computer at an astonishing speed. ECUs have been made quite powerful these days to manage and monitor the large data inputs. There are presets as well, presets of possible pressures, speed and level calculations that are loaded on to the computer by engineers after vigorous testing to determine the safety thresholds.
If the vehicle begins to over steer, the sensor on the suspension and the yaw sensor, which records speed, send the data to the on-board computer. The computer then initiates the ESC emergency sequence that helps return the vehicle to control and stability. This takes place with a number of electronic stability control procedures occurring simultaneously in a matter of split seconds.
it monitors and takes charge of the vehicle without waiting for the drivers input. Those few split seconds gained, can be the difference between life or death.
Unlike the ABS brakes, which waits for the drivers input, the electronic stability control takes the required counter measures on its own without the drivers input. It is linked to the throttle and brakes, and begins by cutting off the throttle to reduce thrust. At the same time, the senses on the suspension indicate which wheels are under the highest stress, thus commanding the opposite wheels to break and keep the vehicle stable.
Since ABS brakes only have sensors to determine the thrust of a vehicle and speed of the wheels, they require the driver to press the brake to begin working. For today’s standards, it is not very effective at preventing the loss of control. The electronic stability control in this case works wonders since it monitors and takes charge of the vehicle without waiting for the drivers input. Those few split seconds gained, can be the difference between life or death.
