brose PMRG33375 Peripheral Monitoring Radar Sensor

Product Information

The product is a sensor system designed for vehicle doors. It utilizes radar technology to monitor objects and provide collision  prevention capabilities. The sensor system is sensitive to environmental conditions, vehicle state, and technology-relatedlimitations, which may affect its performance.

Basic Information

Environmental Conditions:

• Snow, ice, heavy rain, or dirt can reduce the sensor’s performance and may lead to system failure.
• To ensure maximum performance, keep the sensors clean and free from obstructions and dirt.
• Occasionally wipe the cover material (door handle or door trim) with a soft, damp cloth to remove any buildup or dirt.
• Avoid using a high-pressure power washer to prevent damage to the vehicle door.

State of the Vehicle:

• The sensor’s full performance is guaranteed only if the vehicle is in its original condition.
• Aftermarket paintwork, foil wrapping, stickers, scratches nearthe sensor, defects in the sensor’s plastic cover, misalignment ofthe sensor, and vehicle attachments can affect the sensor’s performance.

Technology Related Limitations:

• The sensor may be affected by other electrical equipment that generates high-frequency electromagnetic waves.
• The sensor can only monitor objects within its field of view, which may not cover the entire swing area.
• Objects outside the field of view or at the edge may not be monitored.
• Objects with low Radar Cross Section (RCS) or high velocity may not be monitored.
• If an object is moving towards the door, the sensor can stop the door but cannot prevent a collision if the object continues to move towards the door.

Product Usage Instructions

Repair Shop Instructions:

When repairing the vehicle door or replacing the sensor, follow these instructions to ensure proper sensor function and maximumperformance:

• Do not repaint the areas near the sensor.
• If the sensor’s cover is defective or the paint is scratched, replace the component.
• Obtain replacement parts from the OEM to meet material, paint, and paint film thickness requirements.
• If the cover is defective, consider replacing the sensor as well.
• Ensure sensor assembly inside the handle is done according to assembly requirements.

Assembly:

• Handle the sensor by touching only the case without touching the connector pins and foil.
• Use suitable ESD (Electrostatic Discharge) equipment to prevent damage.

Basic Information

General
The Peripheral Monitoring Radar sensor (PMR) is a system element of a vehicle Side door drive Access Module (SAM). PMR will radiate when SAM requests radar to report obstacles that may collide with vehicle door. If the sensor detects obstacles in the swing volume of the door, it will send obstacle information to SAM allowing the control system of SAM to stop the movement and/ or inform the users before colliding with the object and thus assist the users in their care to prevent from collision during the opening movement. However, doors equipped with a sensor are not guaranteed to detect all objects. Object detection is only an aid and cannot replace the vehicle occupant’s attention to the immediate surroundings when opening and closing the doors. The responsibility for safe opening and closing of the doors always lies with the vehicle occupants.

Environmental Conditions
Various environmental influences can negatively affect the reliability of the sensor’s performance:
Snow, ice, heavy rain or dirt may reduce the performance of the sensor up to failure of the system. A message may be displayed if the system limits are reached. To ensure maximum performance of the sensors, keep them clean and free from obstructions and dirt. Occasionally, remove any buildup or dirt by wiping the cover material (door handle or door trim) with a soft, damp cloth. Avoid using ahigh-pressure power washer to prevent damage of vehicle door

State of the Vehicle

Full performance of the sensor can only be guaranteed if the vehicle is in its original condition. This includes but is not limited to:

• Aftermarket paintwork applied incorrectly near the sensor
• Foil wrapping, especially chrome foil, and stickers
• Scratches in the paint near the sensor
• Defects in the plastic covering the sensor
• Misalignment of sensor
• Vehicle attachments (i.e., caravan mirrors)

Technology Related Limitations

The radar technology has the following limitations:

• The sensor may be affected by other electrical equipment, especially devices that generate high-frequency electromagnetic waves.
• The sensor can only monitor objects that are within its field of view. The field of view may not cover the whole swing area.
• An object outside the field of view or at the edge of the field if view may not be monitored.
• An object with low Radar Cross Section (RCS) may not be monitored.
• An object with high velocity may not be monitored.
• If an object is moving towards the door, the door can be stopped but the sensor cannot prevent a collision with the object if it continues to move towards the door. (Example: shopping cart moving towards stopped door)

Repair Shop Instructions

When repairing the vehicle door or replacing the sensor on a vehicle, there are a few points to keep in mind to ensure proper sensor function and maximum performance:

• Do not repaint the areas near the sensor.
• If the cover of the sensor is defective or the paint is scratched, the component must be replaced.
• To ensure that requirements for material, paint and paint film thickness are met, the replacement part must be obtained from the OEM. If the cover is defective, it can be assumed that the sensor has also been damaged and replacement of the sensor should be considered.
• Sensor assembly inside the handle must be in accordance with assembly requirements.

General Handling

• The sensor is an electrostatic discharge (ESD) sensitive component and must be handled accordingly.
• Personnel must use suitable ESD gear and equipment to prevent damage of the electronics.
• Personnel must be trained and follow appropriate ESD practices and procedures.
• Transport ESD sensitive parts only in proper ESD packaging.
• Workstations must be kept clean and organized to prevent damage from contamination of the product.
• Reduce Handling of the device to a minimum to minimize the risk of damage.
• Check and replace gloves regularly to prevent damage from contamination caused by dirty gloves.
• If there is mechanical damage to the housing or the housing is contaminated the sensor can no longer be installed.
• If there is mechanical damage to the foil covering the sensor, the sensor can no longer be installed.
• If there is mechanical damage to the retaining clips, the sensor can no longer be installed.
• Do not use components that have been dropped due to risk of damage or deformation.

Assembly

• Handle the sensor by touching only the case without touching the connector pins and foil. Use suitable ESD equipment.
• Special care must be taken to avoid touching the foil covering the sensor electronics.
• The label must be scanned to ensure the correct hardware and software version is built in the corresponding vehicle.
• Use a suitable tool for positioning and fixing the sensor without mechanical shocks or stresses. Do not apply high mechanical force during mounting process.
• Position the sensor correctly in its mounting location to ensure the proper performance.
• The sensor must be connected to the original wiring harness of the vehicle with a suitable tool.
• Ensure that there are no failure conditions caused by short circuits to ground or battery voltage.
• Ensure successful connection of the connector before powering the sensor.
• Ensure that the sensor cover (door handle, door trim) is positioned correctly and not damaged.
• A special calibration of the sensor function does not need to be performed.

Disassembly

• Remove the ECU with suitable tools.
• Avoid mechanical shocks, stresses, and high mechanical forces to prevent damages during the disassembly procedure.
• Ensure that the retaining clips are not damaged. If they are, the sensor mounting must also be replaced.
• Only disconnect the ECU when it is not powered
