How the Japanese Car Anti-Collision Feature Works for Hundreds of Million Prices


Passenger cars over IDR 500 million are equipped with many cutting-edge features which of course provide benefits to their owners. These features are presented not just as complements, but also active safety supporting features.

It is called active safety because it is able to anticipate potential accidents. One of them is an active safety feature on the Pajero Sport Dakar 4X4 8 speed automatic transmission.

The SUV, which is assembled in Deltamas, Cikarang, West Java, is equipped with three advanced features, namely the forward collision mitigation system (FCM), ultrasonic mis-acceleration mitigation system (UMS) and adaptive cruise control (ACC).


The FCM is a radar-based automatic braking sensor that detects objects ahead. The goal is to prevent collisions with vehicles in front that are detected by radar.

For information, this FCM feature can be set from far, medium, close , and inactive. This feature can be activated by pressing the button on the dashboard to the right of the driver. Far FCM mode is active at a distance of 10 meters with the vehicle in front of it.

Both UMS, a feature that is able to hold the car still for five seconds. A sophisticated technology to operate the brake system to avoid collisions due to driver negligence.


When tested on the freeway, this feature proved to be very swift to restrain the vehicle's speed so that there was no collision with the car in front. But before the five second count is over, the driver's foot should press the brake pedal.

Comwhen testing it deliberately did not press the brake pedal within five seconds, instead the car moved forward. This is because the module gets a command for brake release. This means that behind the sophistication of the UMS feature, the rider's feet are also needed. You don't want the system to release the brakes by itself without the driver anticipating it.

Indeed, before the computer automatically orders to release the brake system, the driver will hear a warning sound to immediately press the brake pedal. The sound is accompanied by a 'brake' indicator light on the meter panel in front of the driver.


The third is ACC, a feature similar to cruise control. Before discussing further about ACC, you should understand the work of cruise control.

Cruise control is a technology that gives drivers the freedom to drive a car without having to press the gas pedal. While ACC is a sophisticated technology for future cars whose sophistication exceeds cruise control . It's no exaggeration to call it a semi-autopilot feature.

The benefits of ACC can be enjoyed after the driver activates this feature on the Pajero Sport. Initially press the settings button to determine the speed like other cruise control features.


In general, the cruise control feature is only able to maintain a constant speed, but the advantage of ACC is that it is able to adjust the speed of a vehicle about 100 meters ahead, based on a test conducted by CNNIndonesia.com on a freeway.

The ACC feature really makes the driver free to drive without stepping on the gas and brake pedals. A car equipped with this feature is able to tail the vehicle in front of it without fear of a collision.

When the feature works to read the vehicle in front, the computer will give orders to hold the vehicle speed. Then ACC will give orders to increase speed if the car in front is moving even faster.


The minimum speed limit for activating ACC is 40 km per hour. In other words, ACC is not suitable for use in big cities with heavy traffic.
