  • Patent number: 8131454
    Abstract: A method is described for starting an internal combustion engine having an E-machine coupled to it in a motor vehicle, after the input of a certain torque command at a drive control of the internal combustion engine, the internal combustion engine being accelerated for the start by the E-machine, and the internal combustion engine being set by the drive control, via actuators, to specified characteristics values for the start. To reduce exhaust gas emissions at the start of the internal combustion engine, the internal combustion engine is accelerated by the E-machine, without the injection of fuel, until the engine torque that is able to be implemented by the internal combustion engine, essentially corresponds to the torque command, and the injection of fuel into the internal combustion engine is only then released.

  • Patent number: 7630817
    Abstract: A method for controlling the speed of a vehicle, the method making it possible to maintain a predefined setpoint speed even on downhill grades. In the event that the actual speed of the vehicle exceeds the predefined setpoint speed by more than a first predefined speed difference, a service brake of the vehicle will be activated.

  • Patent number: 7593801
    Abstract: In a method for controlling a speed of a vehicle, when an actual speed of the vehicle exceeds a predefined setpoint speed by more than a first predefined speed difference, a service brake of the vehicle is activated. In the method, the first predefined speed difference has a value greater than zero. Also, when the actual speed exceeds the setpoint speed by a second predefined speed difference, which is smaller than the first predefined speed difference, an idle speed control can be activated and a torque request of activated ancillary components can be reduced. Further, when the actual speed exceeds the setpoint speed by a sixth predefined speed difference, which is smaller than the first predefined speed difference, an ancillary component can be activated.

  • Patent number: 7548812
    Abstract: A method and a device for controlling the speed of a vehicle are described. In the transition from a dynamic to a steady-state operating state, the initially accepted setpoint value is corrected using a correcting value which depends on the system deviation prevailing at the time when the longitudinal acceleration of the vehicle has reached, exceeded, or fallen below a predetermined threshold value.

  • Patent number: 7493981
    Abstract: A method and an arrangement for the speed control of a vehicle as well an operator-controlled element are disclosed which make possible an improved acceleration and/or deceleration input by the driver of the motor vehicle. The speed control takes place in dependence upon a value for an acceleration and/or deceleration of the motor vehicle with this value being pregiven with the aid of an operator-controlled element. The function of the operator-controlled element is different from the function of an accelerator pedal and a brake pedal. With the actuation of the operator-controlled element, one of several different values for the acceleration and/or deceleration is selected and pregiven.

  • Patent number: 7194352
    Abstract: A method and an arrangement for controlling the speed of a vehicle make possible a comfortable adaptation of an incrementation or decrementation of a pregiven desired speed. The desired speed is changed by the actuation of an operator-controlled element (1). The extent of the change of the desired speed is adjusted in dependence upon at least one piece of data as to the instantaneous driving situation of the vehicle.

  • Patent number: 7191041
    Abstract: A method is for making a diagnosis as to signal plausibility in a speed sensor of a motor vehicle. In the method, the speed sensor outputs a pulse sequence to an evaluation circuit in dependence upon the speed of the vehicle and, in a steady-state operating condition of the motor vehicle, a ratio is formed between the determined speed and an engine rpm and the ratio is averaged over a pregiven time. A plausibility is determined only when the formed mean value lies in a value range permissible for the steady-state operating condition.

  • Patent number: 7059999
    Abstract: A method and an arrangement for controlling the drive unit of a vehicle are suggested which prevent a lost motion and a dead path in the interpretation of the position of the accelerator pedal for forming a desired acceleration. An acceleration command is derived from a position of an operator-controlled element (1), especially of an accelerator pedal, and a desired value for an output quantity of the drive unit is formed in dependence upon the acceleration command. A minimum value and/or a maximum value for the acceleration of the vehicle is determined in dependence upon an instantaneous running resistance. The minimum value and/or the maximum value are assigned to respective boundaries of an adjustment range for the position of the operator-controlled element (1).

  • Patent number: 6901325
    Abstract: A method and an arrangement are suggested for limiting the speed of a vehicle to a limit speed with the arrangement not needing an integral component and nonetheless being precise at steady state. A maximum permissible acceleration proportional to the difference between an actual speed and the limit speed is determined. From the maximum permissible acceleration, a limit value for an output quantity of a drive unit of the vehicle is determined by means of a vehicular dynamic operation equation in dependence upon the running resistance. The magnitude of the limit value for limiting the speed of the vehicle to the limit speed may not be exceeded.

  • Publication number: 20040030483
    Abstract: In a method for the control of the speed of a vehicle (1), the desired speed remains stored also after a deactivation of the control for a resumption of the control. For the resumption, the type of the roadway (5, 10, 15) currently driven upon by the vehicle is determined with respect to a maximum permissible speed and the desired speed is limited to this maximum permissible speed with the resumption of the control.
