CMBS Control

The CMBS is operated by the ACC unit. The CMBS has these functions:

Obstacle determination function 

The system determines the potential for collision by the distance from the vehicle ahead and the relative speed based on the millimeter wave radar unit and the predictable course calculated by the driving conditions (wheel speed and yaw rate).

Warning function 

When there is a high risk of collision, the system sends warning directions to the gauge control module and warns by both audible and visual means.

Brake control function 

When there is a high risk of collision, the system sends brake directions to the VSA modulator-control unit and controls braking action.
