  • Patent number: 11059387
    Abstract: In a method for cooling a traction battery of an electrically drivable vehicle, a refrigerant is used as cooling medium, and in a mass flow of specified magnitude is led along the traction battery through at least one channel. The at least one channel is in heat-conducting connection with the traction battery. It is proposed that an available cooling power (PV) for cooling the traction battery is determined, wherein as a function of the available cooling power (PV), the magnitude of the mass flow of the refrigerant is regulated in such a way that either no cooling power (Pactual) is delivered to the traction battery, or the delivered cooling power (Pactual) in each case assumes one of multiple cooling power stages (I, II) as a function of the available cooling power (PV).

  • Patent number: 11052874
    Abstract: The invention relates to a method for authenticating a vehicle user. In the method, movement data of a sensor identification circuit are detected by sensors. The detected movement data are supplied to a self-learning system. The self-learning system ascertains a movement profile based on the supplied movement data and assigns this to a vehicle user. Upon approach of the vehicle by a vehicle user, it is checked whether movement data detected at the point in time of the approach corresponds to a movement profile, which is assigned to a vehicle user authorized to use the vehicle. In the event of a match, the vehicle user approaching the vehicle is authorized to use the vehicle.

  • Patent number: 11052873
    Abstract: The invention relates to a method for operating an anti-theft system of a motor vehicle, comprising a communication system for near field communication and a storage device within a transmission and reception zone of the communication system. The mobile terminal is deposited in a control area in the interior compartment of the motor vehicle, the control area being located outside the transmission and reception zone. The deposited mobile terminal is connected to the communication system by a connecting device, which may, e.g., take the form of a cable, and a wired data communication connection is established. A control unit detects whether the data communication connection has been established with the mobile terminal by the connecting device and detects whether the mobile terminal is authorised to operate the anti-theft system, and depending on whether the authorisation has been detected, activates and/or deactivates a function of the anti-theft system.

  • Publication number: 20210189941
    Abstract: The invention relates to a diagnostic method for checking the functionality of a component for the exhaust-gas aftertreatment of an internal combustion engine. For this purpose, in an internal combustion engine, a secondary air supply is provided by means of which an excess of oxygen can be generated in the exhaust gas channel essentially independently of the operating conditions of the internal combustion engine, and wherein said excess of oxygen is utilized for the measurement of an oxygen storage capacity of the component or of a signal change at the component. It is provided that the component is subsequently subjected to a substoichiometric exhaust gas in order that the oxygen release capacity or the signal change upon a change from superstoichiometric exhaust gas to a substoichiometric exhaust gas is also taken into consideration in the diagnosis.
