Cornering Brake Control or CBC is an automotive safety system developed by BMW. It is a further development and expansion of the anti-lock braking system, designed to distribute braking force during emergency braking whilst cornering. CBC interacts with ABS to counteract oversteer and guarantees optimum distribution of brake power in corners, keeping the vehicle heading in the intended direction even if the brakes are applied suddenly.
How it works
Using the revolutions of the wheel, CBC regulates the pressure in the different wheel brake cylinders so that wheels operate separately and brake optimally. In this way the system intervenes early and the driver is unaware of it. In addition, the physically-dependent over-steering while braking on curves is compensated. CBC counteracts these tendencies by modulating brake action at individual wheels in a precise way; for instance, it can cause brake pressure at the outside front wheel to build up more rapidly than at the other wheels. The result is significantly safer and gentler braking. The vehicle remains safe on track at all times. Even during abrupt braking maneuvers, the vehicle remains stable.
