Abstract: A system and a method for communicating over a Bluetooth Low Energy (BLE) connection in a vehicle. The method includes the steps of: establishing a Bluetooth Low Energy (BLE) connection between a mobile device and a BLE system in the vehicle, wherein the establishing step includes receiving first credentials of the mobile device at the BLE system; providing second credentials to the mobile device from the vehicle, wherein the second credentials are different than the first credentials; and receiving a message from the mobile device that is encrypted using the first and second credentials.

Abstract: A mobile communication system that includes a vehicle and a mobile device is provided. The method pertains to revoking communication control privileges of the mobile device previously authorized to control the vehicle. The method includes the steps of receiving a revocation request at the vehicle via a user interface device, the revocation request including a request to revoke the communication control privileges of the previously authorized mobile device, wherein the control privileges includes a capacity to remotely command at least one of a plurality of vehicle functions; and based on the revocation request, revoking at the vehicle the communication control privileges of the previously authorized mobile device.

Abstract: An oil-lubricated automotive volumetric vacuum pump includes a circumferential pump room wall surrounding a pump room. A rotor comprises a rotor body with an oil receiving cavity and a guiding slot. The rotor body is adjacent to the pump room wall. The rotor rotates inside the pump room. A vane with a vane body and a vane end portion shifts in the guiding slot. The rotor body, the vane, and the circumferential pump room wall define at least two pump chambers. An oil discharge channel with a flow opening in a plane is arranged at the vane end portion of the vane and/or at the guiding slot. The flow opening opens so that oil can flow from a pump chamber through the oil discharge channel to the oil receiving cavity only in a retracted position of the vane end portion during a final compression phase of the respective pump chamber.
