What is Perodua Smart Drive Assist? This is All You Need to Know

Released in 2008, the Volvo XC60 was the first car to constantly monitor and avoid the possibility of a front-to-rear crash by using a laser in the windscreen. This is similar to the Pre-Collision Braking (PCB) under Perodua Smart Drive Assist (PSDA). Every car manufacturer has a different name for their advanced driving assistant, but they all fall under what is known globally as Advanced Driver-Assistance System (ADAS).

The Advanced Driver-Assistance System (ADAS) is a set of advanced driving assistance designed to increase the safety of driving, while improving the driver’s ability to react to dangers on the road and mitigate potential collisions or accidents.

The Perodua Smart Drive Assist (PSDA) is no different than ADAS; it’s a suite of active safety systems to protect the driver and people around. The all-new 2018 Perodua Myvi was the first car from Perodua to include ADAS or in Perodua’s marketing terms – the Advanced Safety Assist (A.S.A), which included Pre-Collision Warning (PCW), Pre-Collision Braking (PCB), Front Departure Alert (FDA), and Pedal Misoperation Control (PMC).

About a year later, the 2019 Perodua Aruz received an updated A.S.A known as the A.S.A 2.0.  In 2021, the Perodua Ativa later received the A.S.A 3.0, followed by the 2022  Perodua Myvi facelift.

Here are the differences between all iterations of A.S.A:

4 – 60 km/h (Pedestrians)

Pre-Collision Braking (PCB) Number of Times Max. 3 times only and engine must be restarted to  reset the system Unlimited times

The top of the range Perodua Myvi and Ativa (AV variant) received the full suite of PSDA which on top of A.S.A 3.0, it includes Lane Keep Control (LKC), Adaptive Cruise Control (ACC), Blind Spot Monitor (BSM) and Rear Cross Traffic Alert (RCTA).

How Do the Features Work?

  • Pre-Collision Warning (PCW) warns the driver via a buzzer and warning lights displayed on the meter upon detecting a risk of frontal collision.
  • Pre-Collision Braking (PCB) controls the brakes to assist in collision avoidance and mitigate collision damage. It will also alert the driver with a buzzer.
  • Front Departure Alert (FDA) alerts the driver when the vehicle in front has moved, usually when the car has stopped at a traffic light or in a traffic jam. FDA notifies the driver to start moving.
  • Pedal Misoperation Control (PMC) suppresses engine output and automatically applies the brakes when the driver accidentally stomps on the accelerator pedal. This also works in a parking lot when the car is facing a wall and the driver wants to reverse but mistakenly shifts the gear into ‘D’.
  • Lane Departure Warning (LDW) warns the driver via a buzzer when it detects unintentional departure from the traveling lane.
  • Lane Departure Prevention (LDP) assists the driver to avoid unintended lane departure. If the driver does not respond to the warning buzzer, the system applies a small corrective force to the steering wheel to assist the driver in keeping within the lane.
  • Adaptive Cruise Control (ACC) allows the car to travel at a constant pre-selected speed and automatically adjusts the vehicle speed to maintain a safe distance from the vehicle ahead.
  • Lane Keep Control (LKC) is a function that supports necessary steering operations to keep your car within a road lane. LKC works together with ACC but itdoes not work when ACC is inactive.
  • Blind Spot Monitor (BSM) addresses blind spots by detecting vehicles that are out of the viewing angle, using indicators on the side-view mirror.
  • Rear Cross Traffic Alert (RCTA) is a support system that detects incoming or approaching vehicles from behind.

How Do You Use PSDA?

  1.   PSDA or A.S.A utilizes two cameras (stereo cameras) mounted in the front of the inside rear view mirror which detects vehicles up to about 70 meters (pedestrians up to 45 meters) ahead.
  2.   In order for the PSDA or A.S.A to operate properly, the windshield view in front of the cameras cannot be obstructed by something (dirt, fog, stickers, etc.).
  3.   The PSDA or A.S.A is turned on automatically upon starting the engine unless the driver turns it off. The A.S.A button is located next to the steering wheel on the right side, below the cupholder.
  4.   Press and hold for more than two seconds to turn on or turnoff the A.S.A function.
  5.   Its operational status is notified by the buzzer and display.
PSDA and A.S.A Functions  Operational Status
Pre-Collision Warning (PCW)
  • When the system determines there’s a risk of collision, it will alert and urge the driver via the buzzer and display to take evasive action.
  • Works at 4 – 120 km/h (vehicles,  motorcycles, or bicycles).
  • Works at 4 – 60 km/h (pedestrians).
Pre-Collision Braking (PCB)
  • When the system recognizes the front obstacles and determines that there is a high collision risk, it will change the buzzer sound and control the brakes.
  • Speed difference between front obstacles is:
      • 4 to 120 km/h (vehicles / motorcycles / bicycles)
      • 4 to 60 km/h (pedestrians)
  • If brake pedal is depressed under the following conditions, PCB will decelerate with more braking force than normal:
      • 30 to 120 km/h (vehicles,  motorcycles, or bicycles)
      • 30 to 60 km/h (pedestrians).
Front Departure Alert (FDA) Warning sound when your vehicle keeps stopping although the vehicle ahead has already moved forward more than three meters away.
Pedal Misoperation Control (PMC) Stereo camera recognizes obstacles  four meters ahead and pressing the wrong pedal while driving slowly approximately 10 km/h or slower.
Lane Departure Warning (LDW)
  • Engine switch is ‘ON’.
  • The car is going at 60 km/h or more.
  • LDW warning OFF indicator is ‘off’.
  • Turn signal indicator is off for four seconds after the turn signal indicator is turned off.
  • Vehicle lane width is approximately three to four meters.
Lane Departure Prevention (LDP)
  • Engine switch is ‘ON’.
  • When the car is going at 60 km/h or more.
  • LDP warning OFF indicator is ‘off’.
  • Turn signal indicator is off for 1 second after the turn signal indicator is turned off.
  • Vehicle lane width is approximately three to four meters.
Adaptive Cruise Control (ACC)
  • ACC consist of two modes:
      • Distance control mode: Detects the presence of vehicles in front and automatically accelerates or decelerates based on the speed change by the vehicle in front.
      • Constant speed control mode: Allows the driver to drive at a constant speed set by the driver.
  • On the seven-inch digital instrument cluster (display in front of steering wheel) there will be a Driving Assist Display located in the center, it will show the traveling lane.
  • To operate, use the operation buttons located at the right side of the steering wheel.
  • To switch on, click on the ACC button with a car and a gauge icon with an arrow, located on the right side of the ‘CANCEL’ button.
  • The Driving Assist Display will show three bars in between the traveling lane, indicating the distance from the vehicle ahead (three bars = 50 meters, two bars = 40 meters, one bar = 20 meters). To set distance, click on the button with a car and the bars, located on the left side of the ‘CANCEL’ button.
  • When the driver has reached its preferred speed, click on the ‘SET’ button to set the speed.
  • To deactivate ACC, click the ‘CANCEL’ button or depress the brake ever so slightly.
Lane Keep Control (LKC)
  • The car is going at 60 km/h or more.
  • ACC is activated.
  • LKC indicator is lit up.
Blind Spot Monitor (BSM) BSM is automatically switched ‘ON’ upon starting the engine.
Rear Cross Traffic Alert (RCTA) RCTA is automatically switched ‘ON’ upon starting the engine.

When Should You Use PSDA? 

PSDA should be switched on at all times as the human’s reaction time to prevent potential collisions is slower than the system. On the other hand, the advanced driving assistant such as Adaptive Cruise Control (ACC) and Lane Keep Control (LKC) should be utilized during a long drive like an outstation trip or during traffic jams. 

Nonetheless, bear in mind that the PSDA only acts as a driver’s assistance instead of an autopilot machine (self-driving vehicle).

How to Maintain System Efficiency?

  • Follow Perodua’s scheduled wheel balancing and alignment.
  • Regular car washing is best as it  prevents dirt sticking on the windshield and radar sensors at the rear.

Advanced Driver-Assistance System (ADAS) Is Merely an Assistant

It is worth noting that ADAS or PSDA is not “magic”, whereby the driver can choose to sleep off when the system is activated – the cameras and radar sensors are not always 100 percent accurate. It is still highly advisable to keep both eyes on the road and always be alert of what is going on around you. Always remember that driving is a privilege, not a right.
