  • Publication number: 20240123968
    Abstract: A control device is provided for operating a road-coupled hybrid vehicle, which is equipped with an electronic control unit, a first drive unit paired with a primary axle, and a second drive unit paired with a secondary axle. The control unit is designed to receive input variables including a specified sum target creep torque and a command to switch over from the single-axle operation to the two-axle operation with a specified all-wheel factor. The control unit sets a specified target torque for an internal combustion engine of the primary axle according to the all-wheel factor and detects the resulting actual coupling torque of the automatic transmission. If the functional module of the control unit ascertains a difference between the actual coupling torque and the sum target creep torque, the functional module specifies a corresponding target torque for an electric drive motor of the secondary axle to compensate for the difference.

  • Publication number: 20240079975
    Abstract: A control device for operating a roadbound all-wheel vehicle having a first electric drive motor assigned to a primary axle and a second electric drive motor assigned to a secondary axle, including a control unit configured such that, when a defined dynamic driving mode of the driver is identified based on the driver request gradient during a operating mode with the first motor activated and the second motor deactivated for a predefined time window, an overall setpoint moment characteristic predefined by a new driver request is ascertained. This is set, in accordance with an axle distribution factor that is likewise predefined, by reducing the setpoint moment of the primary motor and by activating and increasing the setpoint moment of the secondary motor, even when the predefined overall setpoint moment characteristic lies below a maximum possible moment of the primary motor.

  • Publication number: 20240059159
    Abstract: A drive control system for a motor vehicle able to be operated by an electric motor and having a drive stage selector, an electronic accelerator pedal, a brake pedal, and an electronic control unit that is configured such that a creep function is deactivated when a first alternative automatic drive stage is selected, and that a creep function is activated when a second alternative automatic drive stage is selected. The control unit furthermore contains an appropriately programmed function module by way of which, when the creep function is activated and based on creep pilot control, the creep moment predefined thereby, in the form of a drive moment, is reduced based on a braking request from the driver, wherein a frictional braking moment is activated by the conventional wheel brake system only when the minimum possible creep moment is reached.

  • Patent number: 11358597
    Abstract: A drive control system for a motor vehicle operated by electric motor has a drive position selector device and an electronic control unit which is connected to the drive position selector. The drive control system is configured in such a way that when a first alternative automatic drive position is selected a comparatively high, not freely selectable recuperation level can be predefined and crawl mode is deactivated, and when a second alternative automatic drive position is selected at least one constant recuperation level or a sailing mode can be predefined and crawl mode is activated.

  • Publication number: 20220080942
    Abstract: A control unit for a motor vehicle which includes at least one electric machine for driving one or more wheels of the vehicle and at least one friction brake is provided. The control unit is configured to determine that a one-pedal feel function is to be provided via an acceleration pedal of the vehicle and/or a creep function is to be provided via a brake pedal of the vehicle. Additionally, the control unit is configured to operate the electric machine at least temporarily in combination with the friction brake in order to provide the one-pedal feel function and/or the creep function.

  • 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.
