Alarms parking
The system alarm parking (PDC) with ultrasonic sensor determines the distance behind the car to the nearest obstacle. For this purpose, the rear bumper are four sensor (Fig. 1.69). The sensors feed signals begin with decreasing distance to the secure facility. At a distance of about 1.2 m from the facility (area A in Figure Fig. 1.69) starts to sound an intermittent signal. The smaller the distance to the object, the longer signals. When the distance is already less than about 30 cm (area B in figure Fig. 1.69), the signal begins to sound continuously. A further approach to the obstacle leading to the cessation of identification obstacles.
Inclusion The system is activated when reverse gear is engaged, which is confirmed by sound signal. If no audio signal, so the system does not function. The system should be checked in the service enterprise a Volkswagen.
Shutdown When you turn off the reverse gear.
ATTENTION Alarms parking does not relieve the driver from the need to control the movement of the vehicle. The entire responsibility for the consequences of inconsiderate parking rests with the driver. For sensors exist a dead zone where no people or objects are not recognized. Pay parking focus on young children and animals, as the sensors do not always recognize them. Such obstacles as drawbar trailers, lacquered small diameter rods, fences and barriers, under certain conditions is not sensed by sensors that can inattentive when maneuvering damage the car. |
At a speed of about 15 km / h, the system begins to make mistakes, and to judge the actual distance to the obstacle becomes impossible. For reliable operation of the sensors must be free of dirt and ice. When cleaning the sensor with a steam jet is to be done quickly and at a distance no closer than 10 cm. On cars with a standard trailer hitch with a trailer alarm system when reversing is not included.
