摘要:
A method operates a hybrid drive of a motor vehicle, which hybrid drive has an internal combustion engine and a first electric machine. The method generates, in response to a predefined setpoint torque value, a composite torque which drives the motor vehicle. In a transient operating mode which occurs during a change of the predefined setpoint torque value by a value, the composite torque is generated by summing a drive torque which is generated by the internal combustion engine and a drive torque which is generated by the first electric machine. At least one second electric machine is provided which is switched on during the transient operating mode in order to generate the composite torque of the internal combustion engine and of the first electric machine.
摘要:
A device for operating a drive unit generates setpoint values for controlling the drive unit based on, for example driver-generated input parameters. The device generates a first setpoint value for a front-axle drive and a second setpoint value for a rear-axle drive and includes a load impact damping unit which, in the event of a risk of load impacts, processes the setpoint values so as to damp the load impacts. The load impact damping unit is divided into a first load impact damping filter for processing the first setpoint value for the front axle drive and into a second load impact damping filter for processing the second setpoint value for the rear axle drive, and supplies corresponding filtered setpoint values to these drives.

A vehicle has at least two drive wheels which can be driven in each case by single-wheel drive units which are in particular of structurally identical dimensions and which can be actuated by means of a control device control device determines a target torque which, in a torque distribution unit, can be divided into a first target torque for the first drive unit and a second target torque for the second drive unit. The torque distribution unit is assigned an adjustment unit by means of which the first and/or the second target torque can be corrected with an adjustment factor which can be determined as a function of a torque difference, arising owing to manufacturing and/or component tolerances, between the drive units

The invention relates to a propulsion device for an all-wheel-drive vehicle with a front-axle drive (5, 7) and a rear-axle drive (19; 33, 34), which propulsion device has an electronic control device which defines a drive torque (MSumme) for driving the vehicle based on a driver request. The electronic control device is associated with a torque distribution unit (25), by way of which the drive torque (MSumme) can be variably distributed to the front-axle drive (5, 7) and the rear-axle drive (19; 33, 34) as a function of input parameters generated by a driver-assistance controller (31).

摘要:
For controlling a recuperation behavior in a motor vehicle having a hybrid drive or an electric drive, a basic value of a recuperation torque which is to be used for recuperation is predefined and/or can be set by at least one first operating element, a second operating element is used to set an intermediate value deviating from a basic value for the recuperation torque, after the intermediate value has been set by an operator temporarily, in particular for at least one coasting phase, the intermediate value is used as a recuperation torque, after which switching back to the basic value occurs where a resetting operation is entered.
摘要:
A control device for controlling operation of a motor vehicle having an electric motor in at least three operating states. In a first operating state, the motor vehicle is off; in a second operating state, the motor vehicle is on and the electric motor is not controllable; and in a third operating state, the motor vehicle is on and the electric motor is in operation. The control unit includes a basic control element for turning the motor vehicle on and off, and a gear-shift control element for selecting a gear-shift stage. The motor vehicle can be switched from a first operating state to a second operating state by a signal from the basic control element when the motor vehicle is turned on, and from the second operating state to the third operating state with the gear-shift control element by selecting a gear-shift stage associated with the third operating state.
