Collision Mitigation Braking System™ (CMBS™)

What’s the Benefit?

CMBS™8 is designed to assist drivers in avoiding a frontal collision—or reducing its effects if unavoidable.


The Feature:

The Clarity Plug-In Hybrid’s standard Collision Mitigation Braking System (CMBS™)8 is one of the most sophisticated safety systems available.

  • It incorporates the features of the Forward Collision Warning (FCW)9 system.
  • A part of the Honda Sensing® suite of technologies, CMBS™8 is designed to alert drivers of a potential collision via visual and audible alerts and help the driver take corrective actions.
  • The system can even apply the brakes to help reduce the forces of a collision if the system determines one to be unavoidable.
  • The system is designed to perform in three stages:
    • STAGE ONE: If the system determines there is a risk of collision with a vehicle or pedestrian detected ahead, it will issue visual and audible alerts to the driver.
    • STAGE TWO: If the risk of a collision increases and the driver takes no action, the system will continue the visual and audible alerts, and begin to apply light braking.
    • STAGE THREE: If the system determines that a collision is unavoidable, it will continue the visual and audible alerts, and apply strong braking to help mitigate the forces of the collision.

Important Note: The CMBS™8 system on the Clarity Plug-In Hybrid will not be able to apply enough braking force to prevent all collisions. CMBS™8 also cannot detect all objects ahead; the driver must intervene in certain situations, and must always be attentive when using the system. Also, CMBS™8 may not go through all three stages, and may automatically engage the final stage if the system deems it necessary.
