Yes, some semi-trucks are replacing traditional mirrors with camera systems that provide enhanced visibility and safety features. These systems, like Stoneridge's MirrorEye, use digital cameras and monitors to replace mirrors, aiming to reduce blind spots and improve vision in challenging conditions.
Here's a more detailed look:
How it works:
- Camera Placement:
Trucks are fitted with multiple cameras, often including side-view arms with wide and narrow angle lenses, and a camera for the front corner, a common blind spot. - Monitor Display:
Images from these cameras are displayed on monitors inside the cab, typically in the same locations as traditional mirrors, or sometimes in a central location. - Enhanced Visibility:
The systems offer a wider field of view, reduced blind spots, and improved vision in low-light conditions, which can significantly improve safety. - Additional Features:
Some systems include features like distance lines on the monitor to help drivers gauge distances, trailer safe path prediction, and the ability to record footage for review. - Aerodynamic Benefits:
By eliminating the bulky mirrors, these systems can also improve the truck's aerodynamics, potentially leading to slight fuel savings and increased fuel efficiency, according to Stoneridge. - FMCSA Approval:
The Federal Motor Carrier Safety Administration (FMCSA) has granted exemptions allowing the use of camera monitoring systems as an alternative to traditional mirrors on certain trucks.
Benefits:
- Increased Safety:
Reduced blind spots and improved visibility contribute to fewer accidents. - Improved Efficiency:
Enhanced vision can lead to more efficient driving and better lane changes. - Driver Comfort:
Some drivers report reduced stress, fatigue, and anxiety with these systems. - Potential for Older Drivers:
Camera systems might help older drivers extend their careers by offering improved visibility and easier operation.
