What is the Honda Collision Mitigation Braking System (CMBS) and How Does It Work?

The Honda Collision Mitigation Braking System (CMBS) is a cornerstone of Honda Sensing, their suite of safety and driver-assist technologies. Think of it as an extra set of eyes and a quick-thinking assistant always scanning the road ahead to help prevent or reduce the severity of a frontal collision. This system uses a combination of radar mounted in the front grille and a camera located at the top of the windshield to detect vehicles and even pedestrians in your path.

So, how to Honda Collision Mitigation Braking System (CMBS) actually function in real-time? It operates in stages:

Stage 1: Visual and Audible Warnings
If CMBS detects a potential frontal collision, it first provides visual warnings on your multi-information display (MID) and an audible chime. It’s like a gentle nudge to get your attention.
Stage 2: Light Braking
If you don’t react to the initial warnings and the system senses the risk is increasing, it will apply light braking. You’ll feel a slight tug as the system tries to slow you down and get your attention even more forcefully.
Stage 3: Strong Braking
In a critical situation, if a collision is deemed imminent and you still haven’t taken action, CMBS will apply strong, automatic braking to significantly reduce your speed and, ideally, prevent the collision entirely or minimize its impact. This can feel quite abrupt, but it’s designed to save you from a worse outcome.

The system’s brain, the Electronic Control Unit (ECU), constantly processes data from the radar and camera. It calculates the closing speed and distance to objects ahead, making split-second decisions faster than any human possibly could. Understanding these stages is key to appreciating the layers of protection CMBS offers.
