  • Publication number: 20020069009
    Abstract: A method and a device for setting a gear ratio of the transmission installed in the drive train of a motor vehicle, while a distance and/or vehicle-speed control system (ACC system) is activated. A setpoint variable, as a function of which at least the driving motor of the vehicle is controlled, is input during the activation of the distance and/or vehicle-speed control system. The setpoint variable or a value derived from this setpoint variable is limited in response to the existence of a first operating state, and the gear ratio is then set as a function of the limited variable, or as a function of the limited value. The gear ratio is set as a function of the setpoint variable, or as a function of the value, in response to the existence of a second operating state. The method and device prevent unnecessary and uncomfortable occurrences of downshifting during ACC operation, without losing the option of accelerating sharply, which is required in some instances.

  • Patent number: 6374174
    Abstract: A method for terminating a braking intervention of an adaptive cruise control system of a motor vehicle. The braking intervention is terminated in accordance with a predefined algorithm in response to the driver overriding of the adaptive cruise control system. In this context, the algorithm is formed in such a manner that a jerk-free transition from braking to acceleration of the motor vehicle is ensured, thus increasing the ride comfort. The transition from braking to acceleration preferably takes place in accordance with a linear function. Provision can also be made for stepwise functions. To prevent the braking operation from being terminated prematurely by an inadvertent actuation of the accelerator, provision is made for a threshold value to be adjusted for the accelerator for a desire of the driver to accelerate. This threshold value is dependent on the deceleration during braking.

  • Patent number: 6362729
    Abstract: An apparatus for kinesthetic signaling to a driver of a motor vehicle is described. The apparatus signaling the driver if, in the context of a system for controlling vehicle speed, a deliberate shutdown or one occasioned by a malfunction is imminent or exists; or if, in the context of a system for controlling vehicle speed, a preset maximum deceleration value is not sufficient to prevent a collision between the motor vehicle and a preceding vehicle or an obstacle. The apparatus includes a device that modulates a braking setpoint, or a variable derived from it, in such a way that the motor vehicle experiences a temporally fluctuating deceleration that is perceptible by the driver.

  • Patent number: 6351823
    Abstract: A method and a device for monitoring a computer system which includes at least two processors. A first processor of the at least two processors monitors at least a second processor for correct functioning, by monitoring output signals of the second processor or the variables derived from it, at least with regard to their temporal sequence, their content, or their signal (wave) form. A relay of the output signals of the second processor to further units is blocked when the first processor, separately from the second processor, is placed in an energy-conserving operating mode.

  • Publication number: 20010032048
    Abstract: A method and device for adaptive control of separation distance and/or driving speed of a motor vehicle, at least in a first operational mode an engine of the motor vehicle and in a second operational mode a brake of the motor vehicle being able to be activated as a function of a magnitude, representing an acceleration, the magnitude representing the setpoint acceleration is formed and/or limited at least as a function of at least one base value.

  • Patent number: 6125320
    Abstract: A device includes a first control unit for regulating the speed and/or acceleration of a vehicle and a second control unit for controlling a display with which at least one instantaneous actual speed vFA and a selected desired speed vsetA can be displayed. In order to match the two control units with regard to the prevailing speedometer lead, the second control unit includes an element with which the next higher and next lower selectable desired speeds can be determined. These selectable desired speeds are transmitted to the first control unit.

  • Patent number: 6068574
    Abstract: The invention is directed to a method and an arrangement for controlling an output torque of a drive train of a motor vehicle. A desired value for the output torque is made available by the adjustment of a transmission and by the control of the engine. The desired value is determined on the basis of a driver command signal as well as on the basis of a minimum and/or maximum output torque dependent upon operating variables.

  • Patent number: 5716301
    Abstract: The invention is based on an adaptive transmission control wherein changes in the gear ratio of the automatic transmission are determined in dependence upon the detected position of the accelerator pedal actuated by the driver or variables associated therewith and in dependence upon the vehicle straight-line speed and/or the output rpm of the transmission and/or the motor rpm or variables associated therewith. Also, an adaptive variable is determined which adapts the changes of the transmission gear ratio at least to the driving situation then present. The essence of the invention is that the path data of a navigation system is used to determine the above-mentioned adaptation variable. The navigation system is a known map-supported navigation system. In this way, it is advantageously possible to precisely detect the present as well as future driving and environmental situations to which the vehicle is just then subjected or will be subjected in the near future.
