  • Patent number: 10351136
    Abstract: A method for controlling a rolling or a freewheeling mode of a vehicle having a drive-train with an engine, an automatic or automated transmission and controllable means for interrupting force flow in the drive-train. A current vehicle position and a first road stretch, between the current vehicle position and a road stretch section ahead along which a speed limit applies, are determined. While driving with the drive-train engaged, for the road stretch section ahead, a predicted speed variation, if the force flow in the drive-train is interrupted, is calculated and, based this speed variation, a second road stretch is determined which the vehicle, with the force flow interrupted covers, until a value of the predicted speed variation corresponds to a value of the speed limit ahead. With regard to the determined road stretches, a road stretch point for initiating the rolling or freewheeling mode is determined.

  • Patent number: 8979707
    Abstract: A method of operating a drive-train which comprises an automated shift transmission having an unsynchronized main transmission and a synchronized downstream group that is drivingly coupled downstream from the main transmission. An input shaft of the automated transmission is connected, via a clutch, to a drive aggregate and an output shaft of the automated transmission is connected to a drive axle. When the vehicle is driven and the main transmission is in a neutral position, if the drive aggregate malfunctions, to engage a gear, the downstream group is adjusted to stop transmitting power and thereby coast to a stop. A shifting impulse is applied to a shifting cylinder of the main transmission so that shifting elements, of the main transmission, ratchet over one another and eventually mesh thus engaging the main transmission, and once the main transmission is engaged, the downstream group is brought to a power-flow-transmitting position.

  • Patent number: 8939870
    Abstract: A method of controlling a rolling or coasting function of a vehicle with a drive train having a drive motor, an automatic or automated transmission, a controllable shifting means, a brake device and a drive speed control device. The vehicle speed is regulated by the drive speed control device and the braking device is activated, as needed, when driving on a downhill gradient section. To effectively and reliably use the rolling or coasting function in suitable driving situations, taking into account the influence of the driving speed control device, a rolling or a coasting condition for a downhill gradient taper is checked, when driving on the downhill gradient section, and, when the rolling or coasting condition is satisfied, the transmission controls interrupt the flow of power in the drive train before the vehicle entering a flat area, and/or before the driving speed control device generates an engine torque request.

  • Patent number: 8784267
    Abstract: A method of controlling a rolling or a coasting function of a vehicle, such as a commercial vehicle, having a drive train including a drive motor, an automatic or automated transmission that is controllable by transmission controls, a controllable shifting mechanism for interrupting the flow of power in the drive train, and a driving speed control device. The flow of power in the drive train is interrupted in a suitable driving situation. In order for the rolling or the coasting function to be exploited as efficiently as possible, and still be terminated safely and comfortably, the flow of power in the drive train is restored depending on a selectable difference in speed (?v_F_T) between the current vehicle speed (v_F) and a speed limit (v_T) set by the driving speed control device.

  • Patent number: 8700277
    Abstract: A transmission control device (6) for an automatic or automated transmission (2). A shifting strategy of the transmission control device (6) controls and/or regulates the operation of the transmission (2) based on driving condition data such as vehicle mass, driving resistance, vehicle inclination, vehicle velocity, vehicle acceleration, engine rotational speed and/or engine torque, and based on data about the driver's wishes. The transmission control device (6) continuously calculates the driving condition data of the vehicle mass, driving resistance and/or vehicle inclination based on topographic data of a current position of the motor vehicle, and/or the shifting strategy determines a gear change from an actual gear into a target gear based on topographic data of a defined distance ahead of a motor vehicle. The defined distance ahead of the motor vehicle depends on the currently velocity of the vehicle.

  • Patent number: 8666622
    Abstract: A method of determining the size of a gear interval from a currently engaged gear to a target gear in a transmission. The method includes the steps of, for each current gear and for each possible gear interval from the current gear, recording a limit value for an acceleration or a deceleration in the target gear corresponding to the current gear and the respective gear interval used; for the current gear, starting with the smallest gear interval, applying a loop with successive increases of the gear interval to determine, depending on the current driving situation and characteristic parameters of the vehicle, the acceleration or the acceleration theoretically obtainable in the target gear produced by using the gear interval, which is compared with the respective recorded limit value until the acceleration or the deceleration theoretically obtainable no longer contravenes the limit value. The gear interval is then selected for a gearshift.

  • Patent number: 8521379
    Abstract: A method of operating a vehicle in a freewheel mode or a rolling mode, in which the vehicle has a drive train comprising a controllable drive engine, an automatic or automated transmission, and a controllable shifter for interrupting a flow of power in the drive train. To enable fuel-efficient and low-emission, as well as safe and comfortable driving, it is intended that the freewheel mode or the rolling mode is prognostically activated, deactivated or retained by performing a plausibility check of a currently active, automatic driving speed control function or a driving speed and a distance control function and/or other current driving operation or driving state data. The method includes coordinating and adapting relevant marginal conditions of the active driving speed control function or the driving speed and the distance control function, and of the freewheel mode or the rolling mode, according to the driving situation, and initiating control measures by a transmission control.

  • Patent number: 8494737
    Abstract: A method of controlling the driving mode of a motor vehicle, having a largely automated drive-train including a drive motor, a transmission and a separator clutch arranged between the motor and transmission, such that while driving, if certain operating conditions exist and a speed profile calculated with reference to topographical data and vehicle parameters for a road section lying ahead is suitable, the drive-train is disengaged and driving continues in a coasting mode until the occurrence of a termination signal. To enable coasting operation, the calculated speed profile for the case of immediate opening of the drive-train is determined continually at equidistant successive travel points along the driving stretch and is, in each case, evaluated in relation to lower and upper speed limits. Coasting is only enabled if, for a specified minimum number of successive travel points, the evaluation result is in each case positive.

  • Patent number: 8386123
    Abstract: A method for automatically determining a current offset value for the zero-point correction of a vehicle inclination sensor including the steps of while driving in a first driving direction, the current driving resistance is determined repeatedly, without regard to the sensor and stored temporarily, and a current raw signal value of the sensor is noted. Upon a change in the driving direction, the last-noted raw signal value is stored temporarily and while driving in the second driving direction. The current driving resistance is determined repeatedly, without regard to the sensor and stored temporarily. Then, if the difference between the two stored driving resistances agree with a tolerance threshold, the noted raw signal value is stored as the offset value for the zero-point correction of the inclination sensor.
