CBC (Cornering Brake Control): Notes

CBC is a function that is used when the brakes show a tendency to lock. The function operates in combination with EBD and ABS in order to stabilize vehicle lateral and yaw rate movements in situations when the driver corners while braking. Modulation takes place by braking the four wheels individually.

CBC determines if the vehicle is cornering and approaching oversteer by comparing the four wheel speeds. If the vehicle shows a tendency towards oversteer at the same time as the driver depresses the brake pedal, CBC will begin adjustment.

The function is included in TCS and ESP and is activated before ABS modulation. This means that the function only operates with the brake pressure applied by the driver and regulates brake pressure with help from the inlet and outlet valves. The system limits rear braking force and primarily adjusts the front wheel brakes in order to achieve stability.

• CBC includes functions which prevent activation on roads with uneven surfaces.
