Definitions
- the invention relates to a non-track-bound vehicle according to the preamble of claim 1.
- the vehicle drive operates the generator in the medium voltage range (e.g. at 650 volts).
- the generator for the electrical in the vehicle
- Ancillary consumers such as interior and exterior lighting, fan motors, window heating, seat heating, electric windows etc. is usually one (also for safety reasons)
- Low-voltage supply (for example 12 or 24 volts) is provided, which is realized by a corresponding on-board network with a vehicle battery.
- a vehicle can also be equipped with a memory for storing drive energy, for example with a Short-term storage in the form of a flywheel storage coupled to an electrical generator or with a long-term storage in the form of an accumulator.
- the alternator also provides the electricity necessary to charge the vehicle battery. The latter is then available for the power supply of the electrical auxiliary consumers if the generator does not have enough (the combustion engine is at a standstill) or does not have enough power (low speed, many consumers)
- the medium voltage generated by the generator must first be reduced (above 60 volts) for the current fed in
- the aim is to make the internal combustion engine as small as possible. This tends to mean a reduction in
- Sunroof, seat adjustment, mirror adjustment, automatic climate control, etc. can be realized electrically. This has already resulted in a reinforced alternator or even two alternators being operated in conventional vehicles. Not only is the disadvantage of the high weight of these units to be seen, but you also have to accept a relatively poor efficiency in energy conversion. For example, to generate an electrical power of 1.5 KW, depending on the speed, a mechanical drive power in the order of 3-5 KW is required. For an internal combustion engine with 50 KW output, this is up to 10% of the theoretically available drive power. Especially from
- the object of the invention is to change a generic vehicle with the least possible effort so that its more specific
- the invention is applicable regardless of which machine type is used as a generator (e.g. with permanent or field excitation, with or without electronic commutation) or as an electric drive motor (e.g. synchronous, asynchronous, DC motor).
- a generator e.g. with permanent or field excitation, with or without electronic commutation
- an electric drive motor e.g. synchronous, asynchronous, DC motor.
- Voltage converter required to convert the 5-current required for the electrical auxiliary consumers and for charging the vehicle battery from the originally generated medium voltage (preferably in the range of 60 - 1500 volts, in particular in the range up to 650 volts) to the low voltage of the vehicle electrical system (e.g. 12 or 24 volts).
- the electronic control of the vehicle which is present anyway, and which, depending on the drive power requested by the driver, the operation of the internal combustion engine, the generator and the
- Electric motors for the vehicle drive is influenced, expanded to the extent that in operating phases with a particularly high, i.e. at or close to, the theoretical maximum power requirement (e.g.
- the supply to the low-voltage on-board network can take place directly (via the voltage converter) from the generator.
- the invention can be carried out particularly advantageously in such a way that the voltage converter for supplying the low-voltage on-board electrical system supplies the current from one
- FIGS. 1 and 2 show exemplary embodiments of the invention.
- the invention is explained in more detail below on the basis of the exemplary embodiments shown in FIGS. 1 and 2 as a block diagram.
- the two block diagrams each essentially represent the drive train of a non-track-bound vehicle.
- an internal combustion engine 1 is coupled with its crankshaft to a generator 2 which, for example, is permanently excited
- the DC machine is designed with electronic commutation.
- the generator 2 generates an AC voltage which, after rectification in the rectifier 3, is fed into a DC voltage intermediate circuit 4.
- the drive energy for the operation of the electric motors 8 is taken from the DC voltage intermediate circuit 4, which e.g. are each coupled to a wheel 9 of the vehicle, not shown.
- electric motors 8 are preferably designed as permanently excited direct current machines with electronic commutation (block 7).
- the electric current is supplied to the electric motors 8 e.g. supplied as alternating current (block 7).
- the electronic control that controls the generator 2 is labeled G5T, while the electronic controls of the electric motors 8 are labeled MST; however, only one of them is shown as an example.
- the controls for the electric motors 8 and the generator 2 are superordinate
- the operating voltage in the DC link 4 is in the medium voltage range, preferably around 650 volts.
- electric vehicles must also be in the vehicle
- Ancillary consumers 10 e.g. fans, disc heaters, etc.
- a low-voltage on-board network of, for example, 12 or 24 volt voltage is provided, the one
- Vehicle battery 6 includes. In order to charge the battery 6 and / or to feed the auxiliary consumers 10 during normal driving, the required current is taken from the DC link 4. Since the voltage level of the DC link 4 is significantly too high, the voltage in an electronic converter 5 is reduced down to the range of the vehicle electrical system voltage. In operating phases in which the highest possible power for the vehicle drive is to be made available, the electronic control FST provides that the connection between the DC link 4 and the
- Voltage converter 5 is temporarily interrupted by a switching device (breaker 11), so that the entire current generated by the generator 2 can be supplied to the electric motors 8. During these phases, the supply to the secondary consumers 10 is without
- DC voltage intermediate circuit 4 and the voltage converter 5 are restored by the electronic control so that the battery 6 can be recharged and / or the auxiliary loads 10 are supplied directly from the DC voltage intermediate circuit 4.
- Feeding power into the low-voltage electrical system is equipped with a special device (e.g. special low-voltage winding or circuit) so that there is no need to lower the voltage (blocks 5 or 12). In this case, too, an interruption of the feed into the low-voltage electrical system
- the principle according to the invention can also be applied without difficulty when using alternating current generators and motors. Then, of course, rectification must be carried out before being fed into the vehicle electrical system.
- the advantages of being able to make the full power of the combustion engine available as drive energy at all times without sacrificing comfort when a separate alternator is not required remain the same.
