Embodiment Construction

[0028] figure 1 A schematic diagram of a hybrid vehicle 1 is shown. The hybrid vehicle has a hybrid drive train 2 , of whose components only an internal combustion engine 3 , an electric machine 4 and a transmission 5 are shown here. The electric machine 4 can also operate as a generator for regeneration, it is used here at a voltage level of 48 V and is connected to a corresponding on-board power supply 6 in which a rechargeable electrical storage unit is also provided. Energy device 7, here is the battery.

[0029] The actuators 9 assigned to the individual wheels 8 are also connected to the vehicle electrical system 6 , wherein the actuators 9 can also operate as generators. The actuator 9 can be a stabilizer, a shock absorber, etc., which can in particular itself have an actuator motor. The actuator 9 can be actuated in the resulting active electromechanical chassis system to adapt the height of the body to the wheels 8 , eg to compensate for vibrations or the like. Fo...

Abstract

The invention relates to a method for operating an onboard network (6) of a hybrid motor vehicle (1). The onboard network (6) is connected to an energy storage unit (7) especially a battery, an electric motor (4) of a hybrid drive train (2), and actuators (9) of an electromechanical chassis system that can be operated as generators. The hybrid drive train also includes an internal combustion engine (3). In order to supply at least part of the electrical energy generated by the actuators (9) into the onboard network (6), at least one storage volume (20) of the energy store unit (7) is kept free. At least one piece of driving style information describing a driving style of a driver of the hybrid vehicle and / or at least one piece of condition information describing a current and / or future operation of the hybrid vehicle (1) dynamically match the vacant storage volume (201).

Description

technical field [0001] The invention relates to a method for operating an onboard electrical system of a hybrid vehicle, to which an energy store, in particular a battery, an electric machine of a hybrid drive train, an energy generator of an electromechanical chassis system, is connected. The hybrid drive train also includes an internal combustion engine, and at least one storage capacity of the energy accumulator is kept empty in order to feed at least a portion of the electrical energy generated by the actuator into the vehicle electrical system. The invention also relates to a hybrid vehicle. Background technique [0002] A hybrid vehicle has both an electric machine and an internal combustion engine in its hybrid powertrain. In this case, in particular a hybrid vehicle is provided in which the electric machine has a relatively low power so that it can be operated in a medium-voltage, for example 48V, on-board electrical system. Such a hybrid vehicle can also include a...
