What does Volvo vcm module do?

Manage and control various functions of the vehicle.

Volvo VCM module is the electronic control unit of the vehicle, which is responsible for managing and controlling various functions of the vehicle. It continuously communicates with the brake control module BCM, the engine control module ECM, the integrated instrument DIM and the safety assistance system module SRS. When there is a risk of collision between the vehicle and the vehicle in front, the camera on the windshield will have real-time image recording. At this time, the control module CVM will receive the message, and the CVM approach speed module will send a message to the BCM brake module, and the brake module will increase the brake pressure in the brake system through the BCM hydraulic pump to start automatic braking. At the same time, SRS module will send warning information request to DIM, so as to display collision warning information. In order to make the necessary response as soon as possible when braking, the closing speed module (CVM) requires the BCM hydraulic pump to be started in advance to make the brake pad close to the brake disc and shorten the braking distance when braking the vehicle.
