Over the past few years the number of driver assistance systems explosively increased. Some have even become mandatory in new cars, others are still options. What’s more, you must choose yourself, and what are their advantages and disadvantages?

Thanks to the electronics can a driver be assisted in avoiding accidents or trapping stuurfouten. Since the 1990s, many systems have surfaced, but especially in the past decade, their development and dissemination has increased enormously. Governments have several of them even made mandatory. Manufacturers on their part to install anyway a lot of those systems by default. They do that on the one hand, to anticipate future obligations and, on the other hand as high as possible to score in the crash tests of EuroNCAP, taking into account the existing driver assistance systems and whether they are standard or not. Some insurers even give a discount on their premium if a car is equipped with a number of driver assistance systems such as an automatic emergency brake or a spoorassistent.

  • Mandatory driver assistance systems in new cars
  • Optional driver assistance systems

Mandatory driver assistance systems


ABS (anti-lock braking system for the wheels under the brakes) was invented in 1978 and in 2004, become mandatory for all new cars in Europe. That means that today almost the entire fleet (80 percent) it is equipped. It is an efficient substitute of the ‘pompend brakes’ of the past. Because the wheels do not lock when you hard brake, you keep the control over where the car is going, and you’ll reduce the danger that you go straight to an obstacle slip off.


  • Steering ability is retained when e-stop
  • Shorter braking distance on wet road surface
  • Reduced risk of slipping


  • Vibration in brake pedal can surprise
  • Braking distance is slightly longer on a dry road surface
  • Risk of faster brake pad wear


In 1995 invented ESP is linked to the ABS. This electronic stability control is in november 2014, making it mandatory for all new cars, but that it was for all cars from 2011 onwards on the market were launched. The ESP ensures the stability of the vehicle and make sure that the car is the chosen route faithfully follows. In some cars it can be switched off for when a sporty driving style and, in the first generations, in order to be able to leave on a beijzeld road.


  • Fixes slippers
  • To avoid that you of the road goes off
  • Reduced risk of skidding due to hydroplaning


  • Less stuurkunst required
  • Difficult sometimes driving on ice
  • Still no replacement for winter tires


A bandendrukwaarschuwing assigns the driver to the fact that an (or multiple) band(s) loses pressure. The system is compulsory since november 2014. The work either via the ESP/ABS sensors the speed of rotation of the wheels to calculate margin of 20 percent), or with much more precise pressure sensors on the valves (margin of 5 percent). If your tires leave change, you should not forget to bandendrukcontrole to adjust (reset) so that the new tires can ‘learn’.


  • To avoid that you unknowingly with a low tyre pressure drive
  • Detects a slowly deflating tyre
  • Reduces the risk of a blowout


  • Price of a sensor
  • With some brands you should reach the dealer along for a reset
  • False alerts

Automatic call to the emergency services

The eCall will be mandatory on march 31, 2018, and let the car automatically to the emergency services inform thanks to an integrated sim card. If the car detects that he is involved in an accident is getting hit (for example, because the airbags open up), he calls himself a call center and transmits its exact gps-position and certain identification data. The operator can listen in with what the interior is done and try to make contact with the occupant while the emergency services are alerted. eCall can also be manually turned on by the passengers of the vehicle.


  • Possible time in case of emergency
  • Precise positioning of the vehicle (even in a ravine)
  • Integrated sim card


  • System know the potential number of victims is not
  • Privacy risks in hacking
  • Only works with coverage gsm network

Not compulsory driver assistance systems


The noodremhulp is probably about a couple of years is mandatory, and makes it possible to anticipate a collision. If the radars or cameras of the vehicle, an obstacle or the vehicle notice that are stationary or moving slowly, then it will send the car a signal (visual or sound) to the driver. If that is not responding, the car is self braking. If the driver responds, the system will brake force boosting to help to make the braking distance shorter.


  • Shortened response time
  • Shorter braking distance
  • Efficient for whom is derived


  • Does not detect everything, especially in bad weather
  • Brakes sometimes for no reason
  • Danger of reduced vigilance director

Active (or dynamic) variable speed drive

The active speed regulator works together with the noodremhulp and adjusts the driving speed as a function of the other traffic, without a preset speed to be exceeded, and maintaining a safe distance. Some systems can the car even fully stopped, and leave when the file starts to drive.


  • Relieves the driver files
  • Helps to the speed limit to respect
  • Keep a pre-programmed set-up clearance to


  • Difficult to use outside highway
  • Dangerous to feet far from the pedals to rest
  • Standard clearance sometimes unrealistic


A spoorassistent keeps the car in its lane. With the help of a camera detects the system the road to the car in the right lane. If the car deviates, the system will either give a warning (vibration in the steering wheel or a beep), or the steering wheel to correct. The system is often combined with an active speed controller to a semizelfstandige rijfunctie. This system is always turned off.


  • Easy on and off
  • To avoid that you have a white line exceeds
  • Warning useful in the case of drowsiness


  • System makes a mistake sometimes (bad mark)
  • Confusing driving experience by regularly tegenwringen of send
  • Can lead to too much confidence in the car

Active headlamps and grootlichten

Automatic headlights are generally great and also in unit delves more and more. In addition, it is today even possible that also the grootlichten naturally come and go. This transition can be done with the help of cameras and light sensors, or some systems may regulate the whole beam even permanently.


  • No need to put your hand on the stuurstengel to keep for the grootlichten
  • Optimal use of the headlights (better visibility)
  • Better illumination of the low side and traffic signs


  • Does not work for fog
  • Not always effective when street lighting is weak
  • Can other road users by surprise

Rear-view camera,

The rear camera is without a doubt the lievelingsoptie of city dwellers. To the extent that they are the beeps from parking sensors to something old-fashioned. With this camera you can maneuver to see what is behind the car. Nevertheless, you should also always look what there is a further around the car before you start driving.


  • Facilitates manoeuvres in reverse
  • Helps to have a child, animal, or layer object to notice
  • Ideal to put you into a small place to go


  • Learning curve
  • Sometimes poor picture quality at night or in rainy weather
  • Narrow field of view

360 degree cameras

Some models give a panoramic around the car through the images to blend from cameras on the front, the flanks and the rear of the car, so you get a bird’s eye view on the car.


  • Obstacles clearly visible (sidewalks, other vehicles…)
  • Easy perfectly within the lines to park
  • You no longer need to your neck in turns to squeeze


  • Sometimes poor picture quality at night or in rainy weather
  • Panoramic but still limited visibility
  • Screen is sometimes too small

Automatic parking assistant

It is no longer necessary to bend over backwards and your steering wheel several times left and right to hoepelen: the automatic park assist improvises your car moves in the post. The director must sometimes have the gearbox and the speed control. But some models go even further and draw their plan when the driver is already out of the trailer (in for example a narrow garage).


  • Parking without stress
  • Car detects itself, or place large enough
  • Useful in the city


  • Detection of parking space, sometimes a little too slow for traffic
  • Car in park sometimes too far away from the embroidery
  • In practice rarely used

Detection of cross traffic when reversing

A camera or sensors to detect other cars that straddle approach when the car is reversing. Particularly useful to reverse out of a parking lot to drive.


  • Reduced risk of collision in a car park
  • Sensible addition to rear-view camera,


  • Could lead to careless reversing
  • Risk of unnecessary warnings

Blind spot assist

The dead angle is a major cause of accidents when overtaking or on the highway. To this risk, you should be looking over your shoulder. Or rely on you blind spot assist. In the mirrors, or thereabouts appears a warning light when another vehicle is to the left or to the right, diagonally behind you.


  • Makes invisible hazards in the blind spot visible
  • Signal directly on the side mirrors


  • Also active if no direction is indicated
  • Warns sometimes too long (especially on the right)


With the help of a camera and clever software, the car can certain signs to ‘read’. So recognize some of the models have a stop Sign or overtaking prohibition, but most systems focus mainly on the speed limits to the driver informed him or her, if necessary, to warn. It even goes so far that you can ask to your place to slow down as the limit goes down.


  • A reminder of the prevailing speed limit
  • Avoid fines by absent-mindedness


  • System makes a mistake sometimes (reads sign for the other lane)
  • Sometimes intrusive alerts

Head-up display

Just like in a fighter jet shows the head-up display all kinds of useful information like the speed, the operation of the variable speed drive, multimedia, certain notifications and navigation instructions on the windshield or on a small glass plate.


  • You have to look never of the road pick
  • Adjustable


  • Sometimes too brightly lit
  • Can be annoying or distracting to work
