In the recent past braking quickly to avoid an accident was a very risky maneuver that sent many drivers off the road. In a nightmare scenario where a child runs out onto the road between a pair of parked cars or an animal seems to come out of nowhere, it’s necessary to brake hard. This was known as threshold braking; hard braking was difficult to achieve without locking up the wheels and losing control. It was also necessary to use cadence braking on slippery road surfaces where you would pump the brakes to maintain grip and control. The introduction of ABS changed all this, and we now have cars that are easier to control, let’s take a closer look at what ABS is and how it works.
What is ABS?
ABS is an acronym for Anti-lock Braking System. This is a system that was introduced in the 90s, and it continues to evolve. The purpose of ABS is to avoid wheels from locking up when the driver needs to perform hard braking in an emergency stop. If the wheels don’t lock up the car is easier to control, and it’s far less likely to go into a slide or spin that could make the situation even worse.
How Does ABS Work?
The Nissan Navara, like any modern vehicle, is fitted with an ABS as standard equipment. The system is continuously monitoring each wheel thanks to a tone ring and magnetic speed sensor that’s attached to each wheel. An electronic control unit receives this data and this, in turn, runs the ABS via a pump and distribution block that control the individual brake calipers on each wheel. When hard braking occurs, the electronic control unit will immediately detect if a wheel has become locked because the speed will have dropped to zero, and the wheel will have stopped spinning. Then the ABS starts to rapidly turn the brake calipers on and off to free up the wheel and get it in sync with the other wheels. The driver will notice a pulsing or shuddering sensation from the brake pedal as the ABS applies and the releases brake pressure faster than a human ever could. When ABS is activated, the driver should be able to brake hard without worrying about losing control of the car. Some people confuse ABS with ABE or Autonomous Emergency Braking, but they are very different. In order for ABS to work there has to be some input from the driver, the ABS cannot trigger on its own, and the driver has to initiate a panic stop or hard braking for the system to activate.
The Future of ABS
It may come as a surprise, but ABS like technology has been around since 1908, but the first modern incarnation was fitted to a Jensen FF back in 1966. The technology really came into its own in the late 80s and early 80s, and now every new car has to have an ABS fitted. Despite the proliferation of crash avoidance and automatic safety systems, it’s likely that ABS will be around for quite some time as a last resort braking system that makes our cars much safer.
