In a method for operating a hybrid drive device of a motor vehicle, which has at least two different drive assemblies, especially an electric machine and an internal combustion engine, that are able to be connected to at least two drive trains of the motor vehicle, during the reconnecting of one of the drive assemblies, particularly from a first to a second of the drive trains, or from the second to the first drive train, and/or during a synchronization, a replacement torque substantially corresponding to the torque produced by the one drive assembly is able to be provided by an additional one of the drive assemblies by the at least partial closing of a clutch.

Method for operating a hybrid drive device of a motor vehicle and hybrid drive device and electronic control unit

A method and a control unit for operating a hybrid vehicle, in which at least two units, of which at least one is an internal combustion engine, supply torque for a hybrid vehicle drive. It is provided that an overall required reserve torque be ascertained, and boundary values of currently available reserve torque of each individual unit be determined.

Method for operating a hybrid vehicle and control unit for implementing the method

In a method for operating a hybrid drive of a vehicle having at least one internal combustion engine and at least one first electric machine as drive machines of a first drive train of the vehicle, and an associated first transmission, the total torque of the drive machines is adapted in a shifting operation of the transmission in order to reduce the load at the transmission and/or in order to modify rotational speeds according to the new transmission ratio, and/or the torque gradient of the drive machines is restricted to a specifiable, maximum torque gradient of the resulting total torque of the drive machines of the first drive train in a transition between acceleration operation and trailing throttle operation.

Method for operating a hybrid drive of a motor vehicle

A method and a device for operating a drive unit which enable better torque coordination for a speed controller. A load-reversal damping component is provided, which filters a first setpoint value for an output variable of the drive unit to damp a load reversal. A speed controller is provided, which specifies a second setpoint value for the output variable of the drive unit in order to adjust an actual value for an engine speed of the drive unit to a setpoint value for the engine speed. A first component of the second setpoint value for the output variable specified by the speed controller is taken into account in the formation of the first setpoint value. A remaining second component of the second setpoint value for the output variable specified by the speed controller, together with the filtered first setpoint value, is taken into account only when forming a resulting third setpoint value for the output variable, the first component of the second setpoint value for the output variable specified by the speed controller being formed as a function of at least one characteristic of the load-reversal damping component, in such a way that it is not or only negligibly affected by the filtering.

Method and device for operating a drive unit

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.

Method and arrangement for the speed control of a motor vehicle and operator-controlled element

A method for operating a drive unit, in which, given the use of a vehicle-speed controller, the actual speed is prevented from exceeding the setpoint speed too significantly. In the method, a setpoint value for an output variable of the drive unit is predetermined. An overrun fuel cutoff of the drive unit is enabled as soon as the setpoint value for the output variable falls below a characteristic value for the overrun fuel cutoff.

Method for operating a drive unit

A method and a device for operating a vehicle provide a convenient and flexible function for limiting a performance quantity, in particular the speed or the engine speed of the vehicle. At least one limiting value is predefined for the performance quantity. The at least one limiting value is predefined at an input unit as a function of at least one criterion. A check is made to determine whether the at least one criterion is satisfied. The at least one limiting value is activated if the at least one criterion is satisfied.

Method and device for operating a vehicle

A method is directed to the control of the speed of a vehicle wherein the actual speed is caused to track the desired speed. For reducing the actual speed, a transmission () of the vehicle () is driven to downshift and thereby the brake system is protected with respect to wear and overheating.

Method for controlling the speed of a vehicle

A method and an arrangement for monitoring a deceleration function of a control unit of a motor vehicle affect as little as possible the operability of the control unit in the case of a fault. The deceleration function of a control unit () of a motor vehicle inputs a vehicle deceleration independently of the actuation of a vehicle brake operator-controlled element. The input is transmitted via a deceleration interface () to a brake system () of the vehicle to realize the input. A check is made as to whether a brake intervention of the brake system (), which is initiated by the deceleration function, is permissible and, at first, only the deceleration function is deactivated when the brake intervention is impermissible.

Method and arrangement for monitoring a deceleration function of a control unit of a motor vehicle

A method and a device for controlling the drive unit of a vehicle make possible an effective kinesthetic signaling of an event. Based on a detection of the event, an output variable of the drive unit is changed in a stepwise manner, as a function of whether the vehicle is in an overrun state or an acceleration state.

Method and device for controlling the drive unit of a vehicle

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 (), 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 ().

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.
