Abstract:
1. A method for recovering energy in a braking process of a hybrid vehicle having an internal combustion engine, an electric drive, and one of a hydraulic braking system or a pneumatic braking system, the method comprising: detecting a driver's braking command representing an overall deceleration desired by the driver; ascertaining a deceleration value which is able to be effected by the electric drive; and reducing a braking pressure exerted at at least one wheel brake by an amount depending on the overall deceleration desired by the driver and the deceleration value which is able to be effected by the electric drive; wherein the braking pressure exerted at at least one wheel brake is reduced using a valve situated in a brake line and the valve is activated in a clocked manner.
