Audi A5 e-hybrid quattro Integrated brake control system iBCS

The integrated brake control system with blending capability (iBRS) ensures pressure-free braking and the best possible energy recovery.

When the brake pedal is depressed during deceleration, the A5 Avant e-hybrid quattro and the A5 Sedan e-hybrid quattro can recover up to 88 kW of power and feed it into the HV battery. When operated as a generator, the electric motor accounts for more than 90 percent of all deceleration processes. The integrated brake control system with blending capability (iBRS) ensures pressure-free braking and the best possible energy recovery. The hydraulic wheel brakes are only used for harder braking maneuvers. This has no effect on the braking feel for the driver, as the brake pedal and brake hydraulics are decoupled.

In addition, automatic recuperation can be preset in the MMI in drive levels D and M. The vehicle varies the recuperation autonomously. The parameters for this are route data stored in the navigation system, such as gradients, curve radii, place-name signs, and speed limits. Another important factor is the traffic ahead. As soon as automatic regenerative braking is selected, predictive signals are fed into the overrun regenerative braking function with the help of Predictive Efficiency Assistant (PEA). The new A5 e-hybrid can also perform automatic regenerative braking without active route guidance.
