Parktronic (PTS) system

PTS guarantees the driver with information on removal of the car to a barrier. At the movement of a forward leg only sensors of peredka are activated.

At Rückwärtsfahren become as behind, and a zone hall controllable.

The system is automatically enlisted at key poworatschiwanii in the ignition lock in situation 2 and remains active until the speed of the movement of the car does not pass value into 15 km for an hour, - shutdown of system automatically is also made.

Repeated activization of PTS happens at immersion of speed of the movement of the car below than border in 15 km for an hour.
The possibility of compulsory shutdown of PTS exists with the help definitely on vertical section of the console of the switch (watch administrative bodies and the equipment of salon left).

Serviceability of functioning of the Parktronic system depends on extent of pollution defined on forward poles and back buffers of sensors of ultrasound in a considerable size. Violations can bring ultrasound sources (inclusive squeal of pneumatic brakes of trucks).

The forward zone will be from 6 sensors of ultrasound which are constructed in an overlay of the forward buffer (2 in the middle and on 2 after corners), behind controls - 4 sensors in the back buffer. Width of action of sensors forms 100 cm for the central forward sensors, 60 cm for forward sensors of a corner, 120 cm for the central back sensors and 80 cm for external back sensors.

The minimum admissible removal between a sensor and a barrier forms 15 cm for sensors of a corner and 20 cm for central, the sensitivity threshold is broken further. They follow purity of a surface of buffers.

Light PTS indicators


1 — the indicator on the panel of devices 2 — the indicator in installation of a back lamp 3 — a frame 4 — segments

To a barrier during the parking of the driver the 3-every second acoustic signal notifies on dangerous rapprochement, besides, special light indicators are provided on the panel of devices and in installation for lamp salonnogo. Indicators in 6 turns yellow also to 2 red segments divided which abundance corresponds to activization of removal to the following barrier.

At connection of the electric leading adherent's device to the plug farkopa (at the corresponding complete set of the car) the system is automatically switched off.

In case of violation of serviceability of functioning of PTS red segments of all light indicators of system are activated and the 3-every second acoustic signal is issued, - you check purity of surfaces of buffers. As a last resort you banish the car on Mercedes Benz service station for execution of necessary repair of system recovery.
