  "textContent": "A brake system for a motor vehicle, comprising a friction brake (2) adapted to mechanically apply a braking force to the vehicle, a regenerative brake (4) adapted to apply a braking force to the vehicle, a brake pedal (6) adapted to be moved by a driver of the vehicle through a pedal range from not depressed (Pp 0 ) to fully depressed (Pp max ). The brake system further comprises a control unit (8) which comprises a working memory (10) with control instructions that refer inter alia to a brake pedal characteristic that incorporates inter alia a relationship between pedal depression and braking force BF, which control unit is adapted to activate the friction brake and the regenerative brake depending on pedal depression in accordance with said brake pedal characteristic. The pedal range comprises at least two pedal positions, Pp 1 and Pp 2 which are chosen such that Ppo< Pp 1 < Pp 2 < Pp max and which define three range segments A, B and C, where A is bounded by Pp 0 and Pp 1 , B by Pp 1 and Pp 2 . and C by Pp 2 and Pp max , the control unit being adapted to control the brakes so that in segment A, only the regenerative brake is activated to deliver an increasing braking force BF A in response to increasing pedal depression; in segment B, only the regenerative brake is activated to deliver a substantially constant braking force BF B in response to increasing pedal depression, and in segment C, the friction brake is activated so that an increasing total braking force BF C is applied to the vehicle in response to increasing pedal depression.",
