  • Patent number: 11104233
    Abstract: Method for determining predicted acceleration information which describes a future acceleration potential of an electric vehicle having an electric motor as the drive device, which is supplied with electric power from a battery in the electric vehicle, this method including the following steps: —Supplying power predictive information of the electric motor, which describes the predicted available acceleration power of the electric motor for at least one future period of time, —Determining the acceleration information from the power predictive information by using a vehicle model which supplies the prevailing operating state of the electric vehicle, at least one vehicle parameter describing the acceleration possible on the basis of the acceleration power and/or using predictive path data supplied in particular by a navigation system for the period of time.
    Type: Grant

  • Patent number: 10668810
    Abstract: A method and system are provided for vehicle stabilization of a hybrid vehicle in an event of brake slip of the drive wheels or an increased risk thereof. The method presupposes that the hybrid vehicle includes, between the internal combustion engine and the electric motor, a clutch by which the torque of the internal combustion engine can be decoupled from the drive wheels. With the clutch engaged, the resulting torque on the electric motor is produced by the torque of the internal combustion engine and the torque of the electric motor. The presence of a specific vehicle condition indicative of brake slip of the drive wheels or a risk thereof is recognized. If such a vehicle condition is recognized, the clutch between the internal combustion engine and the electric motor is released and the torque of the electric motor is increased.
