As high-efficiency engines fail to produce enough vacuum pressure to generate the ideal amount of stopping power, German supplier ZF has introduced its answer. The 2019 Chevrolet Silverado and 2019 GMC Sierra are some of the first vehicles to benefit.
It’s called Integrated Brake Control (IBC) and it replaces the vacuum booster and associated cables, sensors, switches, electronic controllers and vacuum pumps. According to a Wards Auto report last Thursday, the system works with a pedal simulator. Fluid in the master cylinder is displaced to an accumulator and the system measures pedal travel. A motor with a ball screw then pushes a plunger to deliver hydraulic fluid to the wheels.
According to ZF, the motor can do all of this and generate brake pressure measuring 1 g in just 150 milliseconds. Automatic emergency braking is also quicker with IBC; the system can deploy full stopping force in a quarter of the time compared to a traditional braking setup.
Another benefit of the system is the ability to incorporate the electronic stability control in the one module. Thus, the 2019 Silverado and 2019 Sierra feature one package for the braking and stability control system. It also saves 11 pounds over traditional components.
ZF added it has contracts in place to provide the IBC system to eight vehicle platforms between multiple companies by 2020. Several more automakers plan to tap ZF for the technology, and there’s a very good chance we’ll see IBC also make its way to the next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade. The SUVs will share the new full-size pickups’ T1 platform.
