Hyundai Xcent gets ABS, EBD as standard

Spread the love

Hyundai’s Dzire rival that had dual airbags now also gets ABS and EBD as standard safety equipment on all variants.

Hyundai has added additional safety kit to its Xcent compact sedan range. The car now comes with standard ABS and EBD on all trims. The Xcent was already available with standard dual airbags on all variants since April last year when the car received a mid-cycle refresh.

Key rivals to the Xcent like the Dzire and Honda Amaze are available with ABS and dual airbags but miss out on EBD, thus giving the Xcent an advantage as far as safety kit goes.

Another change to the line-up is the omission of the mid-level E+ variant. The Xcent is now available in four variants – E, S, SX and SX (O). Following the additional equipment on offer, the updated prices for the petrol Xcent start at Rs 5.5 lakh and go up to Rs 7.69 lakh, while the diesel variants start at Rs 6.42 lakh and go up to Rs 8.61 lakh (all prices, ex-showroom, Delhi).

ABS … What is it?

ABS is an abbreviation for Anti-lock Braking System. It was designed to help the driver maintain some steering ability and avoid skidding while braking.

ABS was introduced in the mid -1980s and has become “standard” equipment on the majority of vehicles sold in Canada. ABS in cars and most multi-purpose vehicles (MPV’s) and pick-up trucks works on all four wheels. This promotes directional stability and allows steering while maximizing braking.

Control under heavy braking
ABS allows you to maintain control of the vehicle. Since four-wheel ABS prevents all wheels from skidding, it allows you to steer the vehicle and still maintain braking.

How does it work?

ABS uses wheel speed sensors to determine if one or more wheels are trying to lock up during braking. If a wheel tries to lock up, a series of hydraulic valves limit or reduce the braking on that wheel. This prevents skidding and allows you to maintain steering control.

 

Why do I want or need this?

In a recent Canadian Automobile Association survey of some 1700 members, 66% correctly associated ABS with vehicle stability in an emergency, and 53% correctly stated that ABS allows the driver to steer while braking.

Since the ABS will not allow the tire to stop rotating, you can brake and steer at the same time. The braking and steering ability of the vehicle is limited by the amount of traction the tire can generate.

If you demand steering while braking, the 100% of traction that the tire can generate will be divided between both tasks. For example, if you require 50% for steering then there is 50% of available traction left for braking. If you require 10% for steering then there is 90% left for braking. Be aware that 100% traction on a dry road is a great deal more traction than 100% traction on ice! Therefore, your vehicle is unable to steer and brake as well on a slippery surface as it can on a dry road.

What is EBD (Electronic Brake Force Distribution) and How Does It Work?

Most of the cars today come fitted with ABS or Anti-lock Braking system. Coupled along with ABS, there is another electronic marvel called the EBD or electronic brake force distribution. Simply put, EBD is a system wherein the amount of braking force on each wheel of the car can be varied taking factors such as load bearing on each wheel, condition of the road, speed of the vehicle and so on.

How does it work?

The simple idea behind an EBD system is that it need not be necessary to apply the same amount of braking force on each wheel so as to reduce the speed of the car or bring it to a complete stop. An EBD system makes use of three components which make it tick. The speed sensors, brake force modulators and electronic control unit (ECU).

1. Speed Sensor: The speed sensor not only calculates the speed of the car, but the speed of the engine also (RPM). One of the scenarios can be that the speed of the wheel might not be the same as the speed of the car. Such a situation can lead to the wheel(s) skidding. The speed sensors calculate the slip ratio and relay it to ECU.

2. Electronic Control Unit: It is a small chip which collects the data from the speed sensors in each wheel and uses the data to calculate the slip ratio (difference between the speed of the car and the rotation of the tyre). Once the slip ratio is determined, it makes use of the brake force modulators to keep the slip ratio within limits.

3. Brake Force Modulators: It is the job of these modulators to pump brake fluid into the brake lines and activate the brake cylinders. The brake force applied on each wheel can be modulated.

all these three components work in tandem and make the EBD work and save your day, every time you brake hard.
