The brake booster is operated via the driver's foot operation, and the brake
actuation is determined by
means of the brake pedal angle sensor.
Depending on the brak
The regenerative braking makes possible brake energy regeneration. The
electrical machine works
here as an alternator and brakes the gears via automatic transmission -

Regenerative braking with help of the drivetrain only effects the rear axle.
The brake force on the rear
axle must not exceed a specific value in proportion to that on the front axle.
