Regenerative Brake System

Brakeand recover energy at the same time – Regenerative Brake System

Apedal feel simulator with a pedal angle sensor supplements the actuation unit.When depressing the brake pedal the simulator provides optimum pedal feel, thedeceleration, however, is realised through the generator. The braking energy isconverted into electric power, which is used to charge the vehicle battery.

Onlyif the required deceleration is not sufficient, then the conventional brakesystem is activated. This generates the remaining braking effect based on thedriving state determined by sensors for wheel speed, yaw rate, lateralacceleration, etc.

Theuse of a conventional ESC unit enables the Regenerative Brake System to performall known braking interventions and stability functions (e.g., ABS, EBV, TCS,ESC, HBA, ACC, etc.)

Benefits:

-Full use of the energy recovery potential

  (serial recuperation concept)

-Optimal for hybrid vehicles as well as electric and

  fuel cell vehicles

-The basic concept and the proven components of the

  conventional brake are mostly retained

-Optimum pedal feel selectable by the vehicle

  manufacturer

-Low noise, almost no pedal vibrations in ABS mode

-Improved crash behavior

-Networking adaptability to further vehicle control

  Systems

TheSBA (Simulator Brake Actuation) simulator conveys optimum pedal feel to thedriver at all times.

Thesystem is ideal for all hybrid vehicles as well as electric and fuel cellvehicles.
