What is the Honda Collision Mitigation Braking System (CMBS)?

The Honda Collision Mitigation Braking System (CMBS) is a core component of the Honda Sensing suite of safety and driver-assistive technologies. Think of it as an extra set of eyes and a quick-thinking foot on the brake, always vigilant for potential frontal collisions.

This intelligent system is designed to help prevent or lessen the impact of a collision with a vehicle or even a pedestrian detected in front of your Honda. It doesn’t replace attentive driving, but it provides crucial support when you might not react fast enough.

How CMBS Works: A Step-by-Step Breakdown

The CMBS operates through a sophisticated interplay of sensors and intelligent software. Here’s a simplified breakdown of its operation:

Detection: Your Honda’s system uses a combination of radar (typically located behind the front grille or bumper) and a camera (mounted at the top of the windshield) to constantly scan the road ahead. It identifies other vehicles, pedestrians, and even some cyclists.
Warning Stage 1 (Visual/Audible Alert): If the system detects a high probability of a collision, it first issues a visual warning (often a “BRAKE” message on your instrument panel or head-up display) and an audible chime. This is your cue to react immediately.
Warning Stage 2 (Light Braking): If you don’t react to the initial warnings and the collision risk increases, the CMBS will apply light braking automatically. You’ll feel a gentle pull, accompanied by stronger visual and audible warnings. This is meant to grab your attention and prompt you to take action.
Mitigation Stage (Strong Braking): Should the system determine that a collision is unavoidable and you still haven’t applied sufficient braking or steering, the CMBS will apply strong, automatic braking. This is the system’s final effort to reduce your speed and, consequently, the severity of the impact.

It’s important to understand that CMBS is designed for mitigation, not complete avoidance in all situations. Its primary goal is to reduce the force of impact, which can significantly lessen injuries and vehicle damage.

Key Components of Your Honda’s CMBS

Understanding the hardware helps you appreciate the system’s complexity:

Radar Sensor: Often located in the front bumper, this sensor emits radar waves to measure the distance and speed of objects ahead.
Camera Sensor: Mounted on the inside of the windshield, this camera “sees” objects and lane markings, helping to identify vehicles and pedestrians.
Vehicle Stability Assist (VSA) Modulator: This unit controls the brake pressure to individual wheels, allowing the CMBS to apply precise braking force.
CMBS Electronic Control Unit (ECU): The brain of the operation, processing data from all sensors and determining when to activate warnings or braking.
Driver Interface: This includes the visual warnings on your dash and the audible chimes that alert you to potential hazards.
