BLIS with Trailer Tow Monitoring is an advanced driver-assistance system (ADAS) that extends the functionality of standard Blind Spot Information System (BLIS) to include coverage of a trailer being towed behind a vehicle. This crucial safety feature helps drivers maintain awareness of vehicles in their blind spots, even when hauling a trailer, significantly reducing the risk of accidents during lane changes.
Understanding the Core Technology
Standard BLIS relies on sensors, typically radar-based, embedded in the vehicle’s rear bumper to detect vehicles in the driver’s blind spots – those areas to the side and slightly behind the vehicle that are difficult to see using mirrors alone. When a vehicle enters one of these zones, a visual alert, usually a light on the corresponding side mirror, illuminates to warn the driver. An optional audible alert may also sound.
Trailer Tow Monitoring enhances this system by accommodating the increased length and width of the vehicle combination. It allows the driver to input the trailer’s dimensions (length specifically) into the vehicle’s system. Based on this information, the BLIS system adjusts its monitoring range to encompass the blind spots created by the trailer.
This means that the system will now detect vehicles in the blind spots not just of the towing vehicle, but also in the blind spots that extend further back and potentially wider due to the trailer’s presence. This expanded coverage is critical for safe towing, as a standard BLIS system would be virtually useless with a trailer attached, leaving the driver vulnerable to blind-spot collisions.
Key Components and Functionality
The functionality hinges on the following elements:
- Radar Sensors: These detect vehicles in the blind spot areas. The range and sensitivity are crucial for accurate detection, especially considering the trailer’s presence.
- Software Integration: Complex algorithms process the data from the radar sensors and determine whether a vehicle is a potential threat in the blind spot. This software also manages the trailer dimensions input by the driver.
- Driver Interface: The system communicates warnings to the driver through visual and/or audible alerts. Clear and concise alerts are vital for quick driver response.
- Trailer Dimension Input: The system requires the driver to input the trailer’s length to accurately calculate the extended blind spot area. This configuration is generally accessible via the vehicle’s infotainment system.
The Importance of Trailer Tow Monitoring
Towing a trailer significantly alters a vehicle’s handling and blind spots. Without a system like BLIS with Trailer Tow Monitoring, drivers must rely solely on their mirrors and over-the-shoulder checks, which can be difficult and prone to errors, especially in challenging driving conditions. The system offers several key advantages:
- Increased Safety: Reduces the risk of collisions during lane changes while towing.
- Reduced Driver Stress: Provides added peace of mind and reduces the cognitive load on the driver.
- Improved Awareness: Extends the driver’s awareness of their surroundings, especially in blind spot areas affected by the trailer.
- Prevention of Accidents: Helps prevent accidents caused by merging into vehicles in the trailer’s blind spot.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions to provide a more comprehensive understanding of BLIS with Trailer Tow Monitoring:
What vehicles offer BLIS with Trailer Tow Monitoring?
This feature is primarily found on trucks and SUVs designed for towing, particularly those from manufacturers like Ford, GM, and Ram. Specific models and availability can vary by year and trim level. Always check the vehicle’s specifications or consult with a dealer.
How do I set up the trailer dimensions in the system?
The setup process typically involves using the vehicle’s infotainment system. Navigate to the towing settings and enter the length of your trailer. Consult your owner’s manual for detailed instructions specific to your vehicle.
Does the system automatically detect the presence of a trailer?
No, most systems require manual setup. You need to inform the system that you are towing a trailer and enter the trailer’s dimensions. This is crucial for the system to function correctly.
What happens if I don’t enter the trailer dimensions correctly?
If the trailer dimensions are incorrect, the system may not accurately detect vehicles in the blind spots, potentially leading to missed warnings and increased risk of accidents. Always double-check the entered dimensions.
Will BLIS with Trailer Tow Monitoring work with any trailer?
The system is designed to work with a variety of trailers, but there might be limitations based on size or configuration. Consult your vehicle’s owner’s manual for specific limitations.
What type of sensors does BLIS with Trailer Tow Monitoring use?
Most systems utilize radar sensors, typically located in the rear bumper, to detect vehicles in the blind spot areas. Some systems may also incorporate ultrasonic sensors.
Can weather conditions affect the performance of the system?
Heavy rain, snow, or fog can potentially affect the performance of the radar sensors. However, most systems are designed to mitigate these effects. In severe weather, visibility is reduced, and drivers should exercise extra caution regardless of the system’s functionality.
Is BLIS with Trailer Tow Monitoring a substitute for careful driving?
Absolutely not. BLIS with Trailer Tow Monitoring is an aid to driving, not a substitute for attentive driving habits, proper mirror adjustments, and diligent over-the-shoulder checks. It is crucial to maintain situational awareness at all times.
What if I disconnect the trailer while driving?
The system will continue to function with the trailer dimensions inputted until you manually disable the trailer tow monitoring or disconnect the trailer in the system’s settings. Remember to disable it after disconnecting the trailer to revert to standard BLIS functionality.
Does BLIS with Trailer Tow Monitoring work while backing up?
While standard BLIS typically focuses on forward motion and lane changes, some systems may integrate with rear cross-traffic alert, which can assist when backing out of parking spaces. However, the trailer tow monitoring aspect specifically addresses blind spots during forward driving.
Can I adjust the sensitivity of the system?
Some vehicles allow you to adjust the sensitivity or warning distance of the BLIS system. Consult your owner’s manual to see if this feature is available on your vehicle.
What maintenance is required for BLIS with Trailer Tow Monitoring?
Regularly inspect the area around the radar sensors to ensure they are free from obstructions like dirt, mud, or snow. Damage to the sensors can impair the system’s functionality. Consult your owner’s manual for specific maintenance recommendations.
Conclusion
BLIS with Trailer Tow Monitoring represents a significant advancement in towing safety. By extending the coverage of standard BLIS to account for the presence of a trailer, it provides drivers with enhanced awareness and reduces the risk of accidents during lane changes. However, it’s crucial to remember that this technology is an aid, not a replacement for responsible driving habits and constant vigilance. By understanding the system’s capabilities and limitations, and by using it in conjunction with safe driving practices, drivers can significantly improve their safety and the safety of others while towing. Always consult your owner’s manual for detailed information specific to your vehicle’s system.
