Abstract

The invention relates to a non-railbound vehicle in which at least one wheel (9) is coupled for driving purposes to an electric motor (8) to which electric power is supplied via power electronics (3, 4, 7) controlled by an electronic system (GST, FST, MST) in accordance with the power requirement set by the driver via a control pedal, in which the power is produced by a generator (2) driven by an internal combustion engine (1), in which the power for running the generator (2) is provided in the medium-voltage range (especially in the range from 100 to 1500 V) and in which there is an on-board system in the low-voltage range (especially below 60 V) which provides the power for subsidiary electrical consumers (10), is fitted with a vehicle battery (6) and is supplied with power which is obtained from part of the mechanical energy generated by the internal combustion engine (1), and in which the generator (2) can be operated as an electric motor to start the internal combustion engine (1).

Description

Non-trackbound vehicle with an electric motor

The invention relates to a non-track-bound vehicle according to the preamble of claim 1.

Rus the publication "Transmissions in vehicles today and tomorrow" (VDI Reports B7ß, 1991, pages 611-622) is a flntriebssystem for non-track-bound vehicles are known, which are equipped with an internal combustion engine whose RbtriebswelLe is coupled to an electric generator. The drive wheels of the vehicle are connected to electric traction motors, which obtain their Rntriebsenergie from the generator. Because of the relatively high performance for the

Vehicle driving (for example, at 650 volts) of the generator operates in the medium voltage range. For the on-vehicle electrical

designated small electric generator ensured, which is driven by the internal combustion engine. The generator also provides the necessary current to charge the vehicle battery. The latter is then available to power the electric auxiliary equipment available if th e ch Li tMachine no (St ill state of the internal combustion engine), or enough electricity ni cht (low speed, many consumers

activated) provides. To start the internal combustion engine, an electric motor (starter motor) is used, which is fed from the vehicle battery and a strong translation (eg 1: 15) to the slower drives the internal combustion engine.

In the publication VDI Reports 878 has already been mentioned that the function of the alternator and the starter can be taken over by the generator that produces the electricity for the electric drive motors with. Additional information about these are not made.

The starter of an internal combustion engine is a special electric motor, which is designed for relatively low speeds and high torque. He must be able to rotate the crankshaft of the engine over the top dead center in the individual cylinders out. The start of the engine usually takes place at speeds in the range

100 to 300 min -1 instead. The starter is designed only for a short-term operation and is tailored in terms of its power supply on connection to a normal vehicle battery of usually 12 or 24 volts.

The coupled with the crankshaft generator of a generic vehicle with all-electric power transmission in the drive train is completely contrast interpreted differently. It must be suitable for continuous use and works normally at much higher speeds of the internal combustion engine (eg, 750 to 5,500 min -1). Also be

In addition to consumer accomplished, can be used. It is noted here that is not only that the applied voltage is not alone

EMF (electromotive force) of the generator at the starting speed has to overcome (eg, 10 volts at 100 min -1), but also the operating voltage of the elements assigned to the generator power electronics (electrical valves). A 12-volt battery is too weak regularly under these conditions. Also, a 24 volt battery is, in many cases, especially when the engine is cold, insufficient.

The object of the invention is to improve a generic vehicle with as little effort to the effect that a start

The internal combustion engine is possible even in the cold state using the generator as a starter motor, if only the normal vehicle battery is available (low voltage below 60 volts) as the power source.

This object is achieved according to the invention with the characterizing features of claim 1. Advantageous developments of the invention are characterized in greater detail in the dependent claims 2 to S.

The invention provides that the time required for starting the internal combustion engine electric power for the generator to

Engine operation must be supplied from an electrical

Buffer is removed, which in turn from the

Vehicle battery is fed. As a buffer in this sense, a tipped with capacitors DC voltage intermediate circuit is used, which is connected downstream of the generator and from which the

according to the electronic control remove the driving energy for driving the power electronics of the vehicle electric drive motors. The tension of this

DC intermediate circuit is in normal operation

preferably in the medium voltage range up to about 650 volts. In some cases it may be useful, even beyond this value still to go. To charge the capacitors, is from the electronic control a line connection from the vehicle battery to

DC voltage intermediate circuit connected. The capacitors are able to provide relatively large currents and thus correspondingly high electrical power is available. Approximately one third of the maximum current is normally already generates a sufficient torque for a safe start. Therefore, a 24 volt battery can be enough under the circumstances. It is more advantageous to equip the vehicle with a voltage converter (such as electronic DC / DC converter), which brings the low voltage Fahrzeugbatterfe to a higher level and therefore allows a higher charge of the capacitors. For extreme cases, such as for the start at very low temperatures, mechanical in combustion engines to large

Resistors carry (tough motor oil, "freezing" of the motor), the invention also provides for a possibility that still allows safe starting even with exceptionally high torque required. This consists in that the crankshaft is firstly not continuously rotated by the motor operated as a generator but is put in swinging movements. The electronic control system then ensures that the back and by the crankshaft herschwingenden

driving the generator at the right point in time, more and more rotational energy is fed successively to the thus self-reinforcing in a vibration beyond the top dead center

The internal combustion engine to get over (pendulum tempering). Thus, a higher starting torque can ultimately be achieved than is possible in itself from the generator under the given conditions of the power supply. This pendulum starting is easily carried out by the controller because it even under normal operation of the generator, which is designed as a multi-pole permanent-magnet direct-current machine with electronic commutation, continuously has highly accurate information of the angular position of the rotor relative to the stator and the rotor to the crankshaft is mechanically rigidly coupled.

The invention makes it avoids having to provide a separate battery with higher voltage only for engine start, which not only causes extra weight, but in addition also claimed substantial volume. As in a conventional vehicle with a conventional starter motor reaches a normal car battery as an electric energy storage. A little construction effort-requiring voltage transformer allows safe starting even under difficult conditions. Based on the shown in the single figure as a block diagram

Embodiment, the invention is explained in more detail below. The block diagram is essentially the drive train of a

non-track-bound vehicle is.

An internal combustion engine 1 is coupled to its crankshaft to a generator 2 which is formed as a multi-pole permanent-magnet direct-current machine with electronic commutation. The generator 2 generates an alternating voltage which is fed, after rectification in a rectifier 3 into a DC voltage intermediate circuit. 4 From the

DC voltage intermediate circuit 4 is removed from the drive energy for the operation of the electric motors 8 which are each coupled to a wheel 9 of the vehicle, not shown. The electric motors 8 as the generator 2 preferably as a multi-pole permanent-magnet

DC motors with electronic commutation (block 7)

educated. The electric current is supplied to the electric motors B as a pulsed direct current (block 7). The electronic controller that controls the generator 2 and the electric motor B, is in the

Blocks GST, FST and MST shown. The overall driving control FST is the motor controls MST, of which only one is shown as an example, and the generator control GST superimposed. Unlike the POWERFUL Luss is the signal indicated by dashed arrows. The operating voltage in the DC voltage intermediate circuit 4 is in the medium voltage range, preferably at about 650 volts. In addition to the electric motors B still have electrical in the vehicle

In addition to load 10 (for example, fans, window heaters, etc.) are supplied with power. For this purpose, a low-voltage network, for example 12 or 24 volt power is provided a

Vehicle battery 6 includes. In order to charge the battery 6 and / or to supply in normal operation the auxiliary equipment 10; the required current is drawn from the DC voltage intermediate circuit. 4 Since the voltage level of the DC voltage intermediate circuit 4 is much too high, the voltage is lowered in an electronic converter 5 up to the range of the vehicle electrical system voltage. To start the engine 1, the generator 2 which is coupled without any intermediate translation to the internal combustion engine 1 is operated as a starter motor. The electronic control FST caused in this connection that the required electric power, which allows such a high current in the winding of the generator 2, the generator 2 a for rotating the

Internal combustion engine 1 emits sufficient starting torque, from the

Capacitors of the DC voltage intermediate circuit is removed. 4 The 12-volt vehicle battery 6 could not make immediately available to this current, as their voltage is too low. unless the

Capacitors of the DC voltage intermediate circuit 4 is not anyway still have sufficient charge from a previous drive operation phase, the electronic control FST first performs a charging of the capacitors of the DC voltage intermediate circuit. 4 This can be done with comparatively low power by the 12 volt battery. 6 In order to achieve a higher charge of the capacitors and thus to make a higher power for the 5tartvorgang available, the means for voltage conversion 5 is advantageously provided that a conversion of the battery current for this purpose to a much higher voltage level (for example 200 or 300 volts) causes , not only the aforementioned 5pannungsverminderung during normal

performs generator operation of power feeding into the low-voltage network. For both tasks separate DC / DC allied could be provided. Once a sufficient capacitor charge is present, the electronic controller can cause the actual process

initiate. The cached electrical energy can flow with relatively high power from the capacitors and produced in the generator 2, a sufficiently high starting torque for the

Internal combustion engine 1. Particularly it is as a generator 2 fitted with a plurality of permanent magnets made of a FeNdB alloy to use electronically commutated electrical machine is appropriate. 6erade at low temperatures have such permanent magnets a particularly high magnetic flux. This results in, for example, -25 ° C to a room temperature over about 3 times as high torque. Even under difficult conditions a pendulum tempering is usually not

required. As a starting process takes only a few seconds, the power electronics is not damaged despite the sometimes very high currents.

The invention is characterized in that with extremely low

Additional costs by taking advantage of already planned for a generic vehicle units a safe start

the internal combustion engine is possible, with a conventional starter motor as a conventional alternator can also be eliminated without replacement. This weight reduction is achieved, which makes itself ultimately in a reduction in specific fuel consumption positive effect.
