Definitions
- Control device for operating a road-coupled hybrid vehicle
- the invention relates to a control device for operating a road-coupled hybrid vehicle with at least one electronic control unit, with a first drive unit assigned to a primary axle (rear axle or front axle) and with a second drive unit assigned to a secondary axle (front axle or rear axle), the drive unit of the primary axle being at least has an internal combustion engine and a transmission and the drive unit of the secondary axle has at least one electric drive motor.
- the German patent application 102012211 920 is based on a so-called road-coupled hybrid vehicle with at least one primary motor (e.g. electric motor), which acts as a drive motor on a first axle of the hybrid vehicle, and with a secondary motor (e.g. internal combustion engine), which acts as a drive motor on a second Axis of the hybrid vehicle acts from.
- a primary motor e.g. electric motor
- a secondary motor e.g. internal combustion engine
- Such road-coupled hybrid vehicles are also referred to as “axle split” or axle hybrid vehicles.
- German patent applications 102012211 920 and 102013208965 deal with methods for switching on the secondary motor.
- the published application DE 102008035451 A1 describes a method for optimizing a hybrid vehicle by controlling the power output of the electric motor in such a way that a power output of the internal combustion engine is controlled to a load point that is optimal for its operating state.
- the overall performance of the hybrid vehicle remains constant.
- the overall performance of the vehicle can be increased by using the electric motor as a generator to charge the electric storage devices of the hybrid vehicle.
- the load point of the combustion engine is controlled in such a way that it can be operated with as little fuel consumption as possible.
- the control device for operating a road-coupled hybrid vehicle is equipped with at least one electronic control unit, with a first drive unit assigned to a primary axle and with a second drive unit assigned to a secondary axle.
- the drive unit of the primary axle e.g. hybrid axle, which, in addition to the combustion engine, 3
- Can have an electric motor) has at least one internal combustion engine and an automated transmission.
- the drive unit of the secondary axle e.g. purely electric axle
- the control unit is configured in particular by a corresponding functional module (computer program product) to receive a specified total target creep torque and a command to switch from single-axle operation to two-axle operation with a specified four-wheel drive factor as input variables.
- the control unit sets a specified target torque for the internal combustion engine of the primary axle in accordance with the all-wheel drive factor.
- the control unit records the resulting actual clutch torque of the transmission, which can be transmitted by the transmission control unit. If the function module of the control unit determines a difference between the actual clutch torque and the total setpoint creep torque, it specifies a corresponding setpoint torque for the electric drive motor of the secondary axle to compensate for this difference.
- the invention is based on the following considerations:
- the invention is intended to realize all-wheel drive crawling with road-coupled axles without a longitudinal transfer case. Here, a clutch-based torque transfer should take place.
- road-coupled hybrid vehicles as described above should be able to creep at least under predetermined conditions in two-axle operation (all-wheel drive), in order to avoid slip, for example.
- hybrid axles or axles with a starting clutch can be controlled in such a way that they only generate part of the torque 4 of the desired drive and transfer it to the other axis through appropriate software programming.
- the creep torque is specified in particular by the transmission control unit and has always been implemented 100% by the coupled transmission axle (primary axle or hybrid axle).
- the transmission control unit itself sends to the electronic control unit, which is provided for the central control of the torques of the drive units, a total target creep torque and an actual torque that the clutch currently issues.
- This total target creep torque is distributed by the electronic control unit as individual target torques to the hybrid and e-axles.
- the transmission control unit attempts to control the clutch(es) in such a way that the "all-wheel" distributed target clutch torque is achieved from the total target creep torque. However, if a difference remains, the E-axis is controlled to compensate for this difference between the total setpoint creep torque and the actual clutch torque.
- the transmission control unit in particular sends the electronic control unit (as the central drive unit or as a hybrid master) a total target creep torque, which is divided between the two axles and sent back to the transmission as a proportionate target torque.
- the gearbox reports a currently transmitted clutch torque.
- the hybrid master coordinates the difference between the total target creep torque and the clutch torque on the second axle. 5
- the transmission control unit could not independently implement the complete total target creep torque due to a fixed all-wheel drive ratio or an all-wheel drive ratio (“AWD factor”) communicated by another system; then the clutch torque is less than the total target creep torque and the E-axle (electric machine of the secondary axle) takes over the difference that is required for creeping in all-wheel drive or two-axle operation.
- ATD factor all-wheel drive ratio
- the drive concept according to the invention is a road-coupled parallel drive (“axle split”). Characteristic of this is a coupling between the electric machine on a first axle (electric axle) and a combustion engine (with an optional second, usually smaller electric machine) on another axle (hybrid axle) exclusively via the road (no mechanical or electrical coupling).
- an exemplary embodiment is considered as an example in which the internal combustion engine is located on the rear axle as the primary axle and the (first) electric machine is located on the front axle as the secondary axle.
- the internal combustion engine can also be located on the front axle as the primary axle and the electric machine on the rear axle as the secondary axle.
- Fig. 1 is a schematic representation of a road-coupled hybrid vehicle with the essential for the control device according to the invention components and
- Fig. 1 is a so-called road-coupled hybrid vehicle F with a first electric drive motor 1 as a drive unit of the front axle VA (defined here as a secondary axle) and with an internal combustion engine 3 as a drive unit of the rear axle HA (defined here as the primary axle).
- the drive unit of the rear axle HA can contain a second electric motor 2 in addition to the internal combustion engine 3 .
- an automatic transmission 4 (in particular a DCT transmission without a torque converter) with at least one controllable clutch 6 can be connected to the internal combustion engine 3 on the input side.
- the invention can also be used analogously for a different sequence of components 2, 3 and 4; e.g. also for an arrangement in which the electric motor 2 is arranged between the internal combustion engine 3 and the automatic transmission 4.
- the front axle VA could also be driven by an internal combustion engine and the rear axle by an electric motor.
- the hybrid vehicle has an electrical energy store 7 which can be charged, in particular, when the electric drive motors 1 and/or 2 are operated as a generator.
- a transmission control unit 8 is assigned to the transmission 4 and communicates with the drive control unit 5 according to the invention.
- the method for controlling the operation of the hybrid vehicle is carried out by the electronic control unit 5, which has a correspondingly programmed function module 10 and connections to the necessary sensors and actuators.
- the function module 10 is implemented, for example, in the form of a software program part (computer program product), the design and functioning of which is explained in more detail by the description of FIG. 7
- Fig. 2 shows the relationships between the parameters that are processed by the control unit 5 according to the invention:
- the total setpoint creep torque M_soll_K_ges is specified, for example by the transmission control unit 8. If the clutch torque M_actual_G in the transmission 4 is exceeded by the setpoint torque M_soll_1 of the primary drive 3 (and possibly 2) cannot be regulated to achieve the total target creep torque M_soll_K_ges, the target torque M_soll_2 of the secondary drive 1 compensates the difference D of the actual clutch torque M_act_G to the total target creep torque M_soll_K_ges.
- the total setpoint creep torque M_soll_K_ges is preferably specified by the transmission control unit 8 if the electronic control unit 5 itself or externally generates a command to change from the four-wheel drive factor of 100% - i.e. from single-axle operation with the primary axle HA - to two-axle or all-wheel drive (e.g. 50%) received.
- a control device for operating a road-coupled hybrid vehicle with at least one electronic control unit 5, with a first drive unit 2 (and possibly 3) assigned to a primary axle HA, and with a second drive unit 1 assigned to a secondary axle VA
- the drive unit of the primary axle HA has at least one internal combustion engine 3 and an automatic transmission 4 with an automatically controllable clutch 6
- the drive unit of the secondary axle VA has at least one electric drive motor 1 .
- the control unit 5 is designed to receive a specified total target creep torque M_soll_K_ges and a command to switch from single-axle operation to two-axle operation with a specified all-wheel drive factor (AWD) as an input variable.
- ATD all-wheel drive factor
- the control unit 5 uses a correspondingly programmed function module 10 to set a specified torque M_soll_1 for the internal combustion engine 3 in accordance with the all-wheel drive factor AWD 8 of the primary axis HA. Furthermore, the control unit 5 detects the resulting actual clutch torque M_act_G of the transmission 4 , which is transmitted by the transmission control unit 8 . If function module 10 determines a difference D between actual clutch torque M_act_G and total setpoint creep torque M_soll_K_ges, it specifies a corresponding torque M_soll_2 for electric drive motor 1 of secondary axle VA to compensate for this difference D.
- the total target creep torque M_soll_K_ges is preferably specified by the transmission control unit 8 when the accelerator pedal FP is not actuated and a selector switch 9 connected to the transmission control unit 8 is in a driving position “D” or “R”.
- the command to switch from single-axle operation to two-axle operation with a predefined four-wheel drive factor AWD is generated when slip occurs at a standstill.
