Definitions
- the invention relates to a motor vehicle, in particular electric or hybrid vehicle, with an electric power source and a control unit associated therewith.
- a hybrid vehicle is a vehicle that has the combination of different drive principles or different energy sources for a drive application within an application.
- different hybridization systems for example micro-hybrid.
- a stop / start operation is possible.
- the system works with the existing electrical system.
- the combustion engine can be switched off when the vehicle is at a standstill, for example at a traffic light or in a traffic jam, and restarted automatically without a noticeable time delay when restarting. With an everyday urban stop-and-go traffic, significant fuel savings are possible.
- a variant of the hybrid vehicle is designed as a combination of an internal combustion engine with one or more electric motors.
- the internal combustion engine can be operated in hybrid drive in a very low efficiency range. Any surplus energy is used by a generator for the electrical charging of the battery.
- the combustion engine and the electric motor work together. sam. For the same acceleration achieved so a smaller internal combustion engine can be provided.
- the reduction of the internal combustion engine compensates in part for the additional weight of the hybrid units.
- a hybrid vehicle has at least one energy store or a battery.
- the energy from this energy store can be used to start the internal combustion engine for the electrical consumers in the vehicle and for acceleration processes.
- recuperation part of the braking energy is fed back into the battery, called recuperation. Especially in city traffic and when driving downhill, recovery helps reduce fuel consumption. If no drive power is required, the internal combustion engine is switched off. This is the case during overrun, standstill or fully charged battery. Another advantage of this design is that it can be relied on a conventional starter, since the electric motor can take over this function.
- An internal combustion engine delivers usable torque only in a specific speed range.
- the electric motor on the other hand, already provides the maximum torque during start-up and allows the torque to decrease at higher speeds. By combining the two engines, each of the better torque can be used and accelerate the vehicle by about 10% to 20% faster.
- Hybrid vehicles typically provide a lower maximum speed due to a lower-power combustion engine, which, unlike conventional vehicles, no longer has to be dimensioned for all driving conditions.
- This driving condition for example when driving fast on the highway, is the only situation which typically requires a high engine power over a longer period of time, which is only required by the Internal combustion engine can be provided.
- the hybrid mechanisms have only limited effect. The acceleration behavior for which both engines are responsible is not affected.
- the hybrid vehicle has a gasoline and an electric motor, which are coupled via a planetary gear to the drive axle.
- the gasoline engine drives the vehicle while the battery is being charged by the gasoline engine via the generator. At heavier load, the vehicle is driven jointly by both engines. In engine braking mode, energy can be recuperated.
- the energy saving compared to gasoline-powered vehicles of the same vehicle class is around 30% according to the current state of the art.
- the drive of the hybrid vehicle in addition to the gasoline engine comprises two electric motors, one on the front and on the rear axle.
- Another design of the drive system provides that the electric motor is not sitting on an axle, but is coupled to a drive train between the engine and transmission.
- considerable saving is made on the technique to be kept, which in turn leads to a lower power requirement and to lower production costs.
- a technical advantage of combining an internal combustion engine with one or more electric motors as a drive is faster intervention in the driving situation stabilization over an ABS / ESP system with conventional hydraulic power unit when the electric motors are coupled with an ESP system, thus in an increased driving safety.
- the invention has for its object to provide a motor vehicle of the type mentioned above, which improves the efficiency and increases the life of the electric power source in such a vehicle.
- control unit is designed to send control signals generated from characteristics characteristic of the previous operating sequence to the electrical energy source.
- the invention is based on the consideration that, according to experience, a motor vehicle is driven in different operating states and with different demands on the power to be provided.
- a motor vehicle is usually designed for a wide range of services, which takes into account both a defensive and a dynamic driving style and the intermediate ranges and the respective corresponding power requirements.
- the power for the electric motor is provided by an electric power source.
- a defensive driving style requires a relatively low power output from the electrical power source, and power is also dissipated over a period of time. In contrast, arise at a dynamic Driving power peaks that are to be done by the electrical energy source.
- an evaluation unit is expediently provided in the motor vehicle, which is connected to the control unit via appropriately designed data lines.
- the characteristic data characteristic of the previous operating procedure can be permanently stored and that newly acquired data can be converted, taking into account previously acquired data, into characteristic data necessary for the demand-oriented power output, it is advantageous to way provided with the controller connected storage unit.
- the advantages achieved by the invention are in particular that the adaptation of the power output of the electrical energy source to a defensive driving style to increase the life of the electrical energy source and the adaptation to an aggressive, aggressive driving style to a higher driving dynamics and thus to a wider Acceptance of the hybrid drive on the target market.
- FIG. 1 a motor vehicle with an electric power source in section
- FIG. 2 shows a schematic representation of the control of an electrical energy source.
- FIG. 1 shows a motor vehicle 1, in particular electric or hybrid vehicle, which has an electrical energy source 2 intended to ensure the energy supply of the motor vehicle 1 in electric mode.
- This electrical energy source 2 is associated with a control unit 4 which controls the power output of the electrical energy source 2 to the associated, not shown here electric motor which drives the motor vehicle 1, controls.
- FIG. 2 schematically shows the sequence of the control of the power output as a function of the parameters influencing the power output.
- the control unit 4 is connected on the data input side to a communication unit 6 which determines the data characterizing the driving behavior and influencing the power output of the electrical energy source 2 during driving operation of the motor vehicle 1.
- the data area includes various characteristics characterizing the driving behavior, which may include, for example, load conditions, speed, accelerator pedal position, shift points and steering movements.
- Control unit 4 transmitted and stored in the memory unit 8 and / or already assigned characteristic data assigned.
- the control unit 4 requests a power output of the electrical energy source 2 on the basis of the stored characteristics for this type of driving operation, which runs in a graphical representation in a flat curve.
- a power request and -delivery takes place a preservation of the electrical energy source 2 and thus an increase in the life.
- the power output of the electrical energy source 2 for a dynamic driving operation of the motor vehicle 1 takes place in a much steeper curve, since the same or a higher power to drive the electric motor 10 of the motor vehicle 1 should be available in a shorter time than in a defensive driving operation. This allows for a more dynamic driving style with higher power peaks, but puts more strain on the electric power source 2, which in turn can result in shorter life compared to use in defensive driving.
- the control unit 4 is further connected to an evaluation unit 12.
- the evaluation unit 12 the recorded, the previous operation characterizing data are evaluated, possibly already existing identification and operating data, which are stored in the memory unit 8, assigned and modified if necessary, and the current characteristics and the modified load data of the electrical energy source 2 via the control unit 4 stored in the storage unit 8.
- the power output of the electrical energy source 2 to the electric motor 10 takes place on the one hand as required by being adapted to the driving behavior and the power requirements of the respective user and to the respective driving operation, on the other hand taking into account the history and the load data of the electrical energy source 2 stored in the storage unit 8. These data and the resulting values for the power output are reported by the control unit 4 to the electrical energy source 2.
- the electric motor 10 drives either a drive axle 14 of the motor vehicle 1 directly or is preceded by a gear 16, which directs the force as needed on an axis or distributed over several axes.
- a gear 16 which directs the force as needed on an axis or distributed over several axes.
