The SCB system incorporates high performance stability control and brake actuation within a 12-volt system architecture and is an integral part of the hybrid Tahoe’s regenerative braking system.
Regenerative braking allows a vehicle to recapture and store part of the kinetic energy that would otherwise be lost to heat when braking. This energy is used to recharge the electric batteries and save on fuel in a hybrid architecture.
The SCB system replaces traditional boosters, master cylinders and vacuum pumps with an electro-hydraulic control unit (EHCU) and brake pedal simulator unit with a twin master cylinder to supply brake pressure. This offers several advantages: ease of installation with fewer components to fit; improved packaging in the front dash area versus traditional vacuum boosters; a decoupled brake pedal that is ideal for integration into autonomous or emergency braking systems; and claimed best-in-class NVH characteristics.
