Adaptive Cruise Control – always at a safe distance.

Adaptive Cruise Control – always at a safe distance.

Volkswagen Adaptive Cruise Control represents an extension of the familiar cruise control system with the addition of a radar sensor. The activated system maintains a preset distance to the vehicle ahead and adjusts driving speed automatically. In this way, Adaptive Cruise Control makes the driver’s task considerably easier and more convenient.

The heart of the Adaptive Cruise Control system is a radar sensor with a mapping range of up to 200 metres and a horizontal opening angle of 12 degrees. The radar sensor and the control unit form a unit and are located, on the new Passat for example, behind the Volkswagen brand emblem in the radiator grille. The advantage of radar technology is that it functions reliably in all weather and road conditions.

Based on the radar sensor’s signals, the control unit calculates not only the distance to the vehicle ahead, but also the relative speed of both vehicles and – if there is more than one lane – the laterally offset position of the vehicle ahead. If there are several vehicles simultaneously in the sensor’s range, the vehicle that is to serve as the basis for the system’s calculations is selected from this information. Stationary objects, e.g. the end of a traffic jam or crash barriers, however, cannot be perceived by the radar sensor.

When approaching a vehicle ahead that is moving more slowly or cutting in, the Adaptive Cruise Control system intervenes in the engine management and, if necessary, in the brake system. If the necessary deceleration exceeds 30 percent of the maximum deceleration, visual and acoustic warning signals instruct the driver to operate the brakes.

Reduced stopping distance – for a faster reaction

Reduced stopping distance – for a faster reaction

On the new Passat, the special function “reduced stopping distance” enhances driving safety. If the distance to the vehicle ahead drops below a critical value, the brakes are prepared for an emergency stop. In practice, this means that the brake pads are applied gently to the brake discs without the vehicle being decelerated. In addition, the response threshold of the brake assist is made more sensitive. This means that if the driver then steps on the brake, full braking power is immediately available. The braking distance can thus be reduced.

The advantages in detail:

The advantages in detail:

  • High convenience for the driver on long journeys. Studies confirm that Adaptive Cruise Control alleviates stress noticeably when driving.
  • Significant increase in safety thanks to the fact that the safety distance is maintained.
  • Automatic and safe acceleration and deceleration on motorways and major roads.
  • Vehicle speed can be set to a speed limit.
  • Makes the driver’s task considerably easier, enabling him to concentrate fully on the road.
