Technology Spotlight: Collision Mitigation Braking SystemTM (CMBSTM)
AcuraWatch is an advanced array of safety and driver-assist technologies available on Acura vehicles. It includes:
• Adaptive Cruise Control (ACC)
• Lane Keeping Assist System (LKAS)
• Road Departure Mitigation (RDM) System
• Collision Mitigation Braking System™ (CMBS™) w/pedestrian-sensing capability
• Forward Collision Warning (FCW) System
• Lane Departure Warning (LDW) System
Collision Mitigation Braking System (CMBS)
Acura’s newest version of its Collision Mitigation Braking System (CMBS) is one of the most sophisticated driver-assist technologies available. It…
• Continually scans traffic conditions ahead of the vehicle
• Alerts the driver when it determines there is potential for a collision
• Takes emergency autonomous braking action to help reduce the severity of a collision if the driver doesn’t take corrective action.
Here’s how it works:
• A Millimeter Wave Radar unit located behind the front grille and a Monocular Camera mounted at the upper portion of the windshield are used to detect vehicles, pedestrians, and other objects.
• The radar unit and camera work simultaneously and cooperatively to control the Vehicle Stability Assist™ (VSA®) modulator, which initiates any required braking. (This “sensor fusion” of radar and camera allows the system to more quickly determine a potential collision, significantly increasing the likelihood of slowing the car and avoiding impact.)
• When CMBS detects a potential collision, visual, audible, and tactile (driver seatbelt e-pretensioning) alerts prompt the driver to take corrective actions. The visual alerts appear on the Multi-Information Display (MID).
• If the system determines that a collision is imminent, full braking force is applied to help reduce vehicle speed and potential collision forces.
• Due to the effectiveness of its sensing capabilities, CMBS can recognize shapes and differentiate between a vehicle and a pedestrian, warning the driver in each case.
• Note: CMBS cannot detect all objects ahead, nor is it intended to replace the driver’s assessment of traffic conditions and control of the vehicle.
o The driver must intervene in certain situations and must always be attentive when using the system.
o Although in certain cases CMBS can stop the car, it is not designed to prevent collisions.
o Based on the conditions, the system also may not perform all visual-, audible- and tactile-alert stages, and may instead automatically engage the brakes if the system deems it necessary.
• CMBS alerts the driver of a potential collision and then takes emergency autonomous braking action to help reduce the severity of a collision if the driver doesn’t take corrective action.
• Note: The driver remains responsible for safely operating the vehicle and avoiding collisions.
Presenting/Demonstrating the CMBS
• During your walkaround presentation, point out the locations of the Millimeter Wave Radar unit behind the front grille and the Monocular Camera mounted at the upper portion of the windshield. Explain how the system works.
CMBS cannot detect all objects ahead, nor is it intended to replace the driver’s assessment of traffic conditions and control of the vehicle.
CMBS cannot detect all objects ahead and may not detect a given object; accuracy will vary based on weather, speed, and other factors. System operation is affected by extreme interior heat. CMBS is designed to mitigate crash forces. The driver remains responsible for safely operating vehicle and avoiding collisions.
