  • Publication number: 20250136076
    Abstract: A control arrangement and a method for deactivating an adaptive cruise control system. The method comprises, in response to a determination of risk of loss of functionality of the adaptive cruise control system while the host vehicle is decelerated by the adaptive cruise control system, determining whether the host vehicle may be braked by the service brake system; and, if so, activating a first failure mode during which the adaptive cruise control system is maintained active to decelerate the host vehicle until a deceleration demand is below a predetermined threshold. The method further comprises, when the deceleration demand is below the predetermined threshold, either ramping down the braking demanded by the adaptive cruise control system over a predetermined period of time and thereafter deactivating the adaptive cruise control system, or directly deactivating the adaptive cruise control system.

  • Publication number: 20240308512
    Abstract: A method is provided for controlling a speed of a vehicle, using a Pulse and Glide (PnG) operation, whereby the speed of the vehicle is controlled about a reference speed. The PnG operation comprises a pulse-phase during which the speed of the vehicle is increased to a first speed, higher than the reference speed, followed by a glide-phase during which the speed of the vehicle is allowed to decrease to a second speed, lower than the reference speed. The method is performed when the PnG operation is to be carried out and when a speed increase to an increased speed, higher than the reference speed, is to be commenced during the PnG operation. The method comprises adjusting the PnG operation such that the speed increase to the increased speed, is carried out by accelerating the vehicle immediately following a speed decrease in the glide-phase to at least the second speed.

  • Publication number: 20240269365
    Abstract: An extracorporeal blood treatment apparatus, comprises: at least a pressure sensor (24, 25) located in a respective measurement site on an extracorporeal blood circuit (6, 7); an electronic control unit (23) operatively connected at least to the pressure sensor (24, 25). The electronic control unit (23) is configured to perform at least the following procedure: receiving from the pressure sensor (24, 25) a signal correlated to a measured blood pressure (P1measured, P2measured) in the measurement site; correcting the blood measured pressure (P1measured, P2measured) through a mathematical correction model to obtain a blood actual pressure (Pinlet, Poutlet) in a reference site other than the measurement site. Between the reference site and the measurement site, a circuit section and, optionally, at least one additional device (18, 27, 28) is/are positioned. The mathematical correction model is a model of a pressure drop in the circuit section and, optionally, in the additional device (18, 27, 28).

  • Publication number: 20240270219
    Abstract: A control device and a method for controlling traveling speed of a vehicle for the purpose of maintaining a vehicle speed equal to or lower than a pre-set downhill speed (vdh-set). The method comprises simulating a vehicle speed profile for an upcoming road section if braking at a pre-identified power level (P1, P2, P3) would currently be requested, thereby obtaining a predicted maximum vehicle speed (vP1,max, vP2,max, vP3,max) and a predicted time until a vehicle speed equal to or within a pre-selected interval (Idh) of the pre-set downhill speed is reached. The method further comprises, if the predicted maximum vehicle speed is equal to or below the pre-set downhill speed (vdh-set) and the predicted time is below a preselected threshold time limit, requesting braking at the pre-identified power level or at an adjusted power level.

  • Patent number: 9360558
    Abstract: A GNSS receiver design is tested, which design includes software for generating position/time related data (DPT) based on raw digital data (dRAW) when the software is executed in a processing unit of the receiver. GNSS signals (SRF) are received via a radio frequency input device while moving the radio frequency input device along a route trajectory. The received GNSS signals (SRF) are fed to a radio-frequency front end of a Representative example of a receiver unit built according to the design to be tested. The radio-frequency front end produces raw digital data (dRAW) representing the received GNSS signals (SRF), and the raw digital data (dRAW) are stored in a primary data storage as a source file (Fsc). The source file (Fsc) is read from the primary data storage, and the source file (Fsc) is processed by means of the software to generate at least one set of position/time related data (DPT).

  • Publication number: 20150220891
    Abstract: A disclosed method is implemented by a voucher server for distributing digital vouchers. The voucher server stores a plurality of encrypted digital vouchers, each being encrypted with a respective one of a plurality of encryption keys and each having an associated identifier. The voucher server receives, from a computing device, a request for a digital voucher, the request including an identifier. The voucher server determines if the received identifier matches an identifier of any of the plurality of encrypted digital vouchers. If the received identifier matches an identifier for a given one of the encrypted digital vouchers, the voucher server transmits the given encrypted digital voucher to the computing device. The voucher server does not have access to the encryption key used to encrypt the given encrypted digital voucher.
