  • Publication number: 20240001907
    Abstract: A hybrid electric vehicle includes an engine that includes a filter collecting PM from exhaust gas. A controller for the vehicle executes a driving force switching process, a motoring process, and a setting process. The driving force switching process reduces braking torque, which is generated by a drive system during deceleration of the vehicle, so that when execution of a fuel cut-off process of the engine is prohibited, the braking torque is less than when execution of the fuel cut-off process is permitted. The motoring process burns and removes PM from the filter by rotationally driving the engine using a first rotary electric machine during deceleration of the vehicle. The setting process sets a vehicle speed for permitting execution of the motoring process to be higher when execution of the fuel cut-off process is prohibited than when execution of the fuel cut-off process is permitted.

    Abstract: Systems and methods described herein concern estimating the mass of a vehicle. One embodiment uses a slope estimator to estimate the grade of a roadway on which the vehicle is traveling; inputs state estimates from the slope estimator, an estimated wheel force, and an estimated wheel acceleration to a secondary mass estimator that calculates a first estimated mass of the vehicle; selects, based at least in part on the first estimated mass, a calibration value using a tuning map; inputs the calibration value, the estimated wheel force, the state estimates, and a measurement noise value to a main mass estimator that calculates a second estimated mass of the vehicle that is more accurate than the first estimated mass due, at least in part, to the calibration value; and adjusts automatically one or more operational parameters of the vehicle based, at least in part, on the second estimated mass.

    Abstract: Proposed is a system for obtaining information when an agricultural vehicle malfunctions. The system may include an agricultural vehicle in which a terminal including a processor and a communication module is mounted, and a server communicatively connected to the terminal. The processor of the terminal may generate a malfunction code when malfunction is detected through a sensor included in the agricultural vehicle. When the malfunction code is generated, the processor may operate in at least one of a first mode or a second mode. In the first mode, raw data obtained during the malfunction code being generated is transmitted to the server through the communication module. In the second mode, raw data obtained before the malfunction code is generated and raw data obtained after the malfunction code is generated are transmitted to the server through the communication module.

    Abstract: Methods for testing a control unit of a vehicle. The control unit obtains calculated surrounding-area data of a simulated surround sensor, and obtains calculated motion data of a simulated vehicle. The calculated motion data are transmitted to the control unit via a simulated vehicle data bus. Using a sensor testing unit, the calculated surrounding-area data are transmitted to the control unit via a sensor-data transmission circuit different from the vehicle data bus. To execute a simulated acquisition of surrounding-area data, using the control unit, a command for executing a measurement is transmitted to the sensor testing unit, data for identifying the position of the simulated surround sensor is transmitted to the computer device, positions of points of reflection by simulated objects in the surrounding area of the vehicle are calculated and transmitted to the sensor testing unit, and calculated surrounding-area data are determined and transmitted to the control unit.

    Abstract: A method determines a defect state of a drive train of a vehicle having a drive axle with a drive wheel and a reference axle with a reference wheel. A drive torque generated by a drive is transferrable to an underlying surface by the drive train via the drive wheel and cannot be transferred to the underlying surface via the reference wheel of the reference axle. The method includes: reading-in a drive variable which is dependent on a motor revolution rate of the drive; reading-in a reference variable which is dependent on a reference wheel revolution rate of the reference wheel; determining whether there is a deviation between the read-in drive and the read-in reference variables to determine whether the reference wheel revolution rate is related to the motor revolution rate of the drive. If there is a deviation, a defect state of the drive train is concluded.
