Beschreibung
Zusammenfassung:	A braking system for an electromobile includes a relief valve VR2 for restricting a braking pressure to front wheel cylinders WC3, WC4, a bypass valve V5 connected in parallel to the relief valve VR2, a solenoid valve V1 interposed between the relief valve VR2 and booster HB and a solenoid valve V4 interposed between a pressure line 13 from the booster HB to the front wheel cylinders WC3, WC4 and a pressure line 12 from the booster HB to rear wheel cylinders WC1, WC2. During a regenerative braking by the use of an electric motor for driving front wheels WFL, WFR, a braking pressure is applied through the solenoid valve V1 and the relief valve VR2 to the wheel cylinders WC3, WC4. When the regenerative braking is interrupted, the solenoid valve V1 is closed and the bypass valve V5 and the solenoid valve V4 are opened.
