The present invention relates to a driving force control device for a hybrid drive vehicle that changes the output of an electric motor to reduce a shift shock of a transmission. 2. Description of the Related Art An automatic transmission generally includes a well-known planetary gear mechanism group, a friction engagement device for fixing or releasing each element of the planetary gear mechanism group, and a hydraulic control device for selectively operating the friction engagement device. And an electronic control unit for controlling the hydraulic control unit. Then, the electronic control unit determines the shift speed according to various running states and controls the hydraulic control device, thereby fixing or releasing each element of the planetary gear mechanism group for selectively operating the friction engagement device. Shift control is performed automatically. Further, a torque converter is connected between the engine and the automatic transmission, and a lock-up clutch is provided therein. The power of the engine is transmitted directly to the transmission when the lock-up clutch is engaged, and is transmitted to the transmission via the torque converter when the lock-up clutch is released. Normally, the engagement and disengagement are controlled based on a shift pattern assumed for each section of the gear position. However, if the shift control is performed in a locked-up state during automatic shift traveling, a large shift shock occurs. There are cases. Various proposals have been made to eliminate such shift shocks. The present applicant has also separately proposed a method of eliminating a shift shock by determining a shift period and controlling a lock-up clutch (Japanese Patent Application No. 61-154332). This method detects the input rotation speed and the output rotation speed of the transmission, finds the ratio, and determines the shift start and shift end by judging this and the gear ratio before and after the shift. Disengage the up clutch, standby, sweep,
Alternatively, it is controlled to a slip state or the like. As described above, conventionally, in order to reduce shift shock of an automatic transmission, the engagement hydraulic pressure of a friction engagement element such as a clutch or a brake, which is a component of the automatic transmission or the like, is gradually increased or supplied or supplied with hydraulic pressure. This was done by properly adjusting the timing of the discharge speed. [Problems to be Solved by the Invention] By the way, the automatic transmission has a complicated control and structure because it performs shift control according to various traveling conditions. Furthermore, if it is attempted to reduce the shift shock by controlling the friction engagement device of the automatic transmission and the lock-up clutch as described above, the hydraulic control device becomes more and more complicated.
Refinement, higher cost, and lower reliability. An object of the present invention is to provide a driving force control device for a hybrid drive vehicle capable of reducing a torque fluctuation (shift shock) generated during a shift period of an automatic transmission. [Means for Solving the Problems] For this purpose, the present invention detects the driving force of an engine in a hybrid drive vehicle that uses an engine and an electric motor as drive sources equipped with an automatic transmission that performs shift control according to running conditions. Driving force detecting means, a driving force detecting means for detecting the driving force of the electric motor, and a vehicle driving force obtained from the driving force of each of the driving force detecting means during the gear shifting period by determining a shift period of the automatic transmission is constant. And a control means for controlling the output torque of the electric motor. [Operation and Effect] In the driving force control device for a hybrid drive vehicle of the present invention,
The driving force of the engine and the electric motor is detected and fed back to the electric motor such that the vehicle driving force obtained from each of the driving force detecting means during the shift period is constant, and the output of the electric motor is changed to change the driving force of the entire vehicle. Is controlled so as not to change, so that the shift shock can be reduced. Embodiment An embodiment will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of a driving force control device for a hybrid drive vehicle according to an embodiment of the present invention, and FIG. 2 is a diagram showing another configuration of a drive force control device for a hybrid drive vehicle according to the present invention. FIG. 3 is a diagram showing a configuration example of a control device, and FIG. 4 is a diagram for explaining a flow of processing by the control device. In the figure, 1 and 13 are automatic transmissions, 2 and 8 are transmission mechanisms, 3
And 12 are transmission solenoids, 4, 10 and 15 to 18 are torque sensors, 5 and 11 are differential mechanisms, 6 and 14 are control devices, 7, 20 and 21
Denotes a motor, and 9, 19 and 22 denote transmissions. In FIG. 1, a front wheel is an automatic transmission 1
, And the rear wheels are driven by a motor 7 by a transmission 9.
(Or a speed reducer). Torque sensor 4
Is mounted between the transmission mechanism 2 and the differential mechanism 5 of the automatic transmission 1 on the front wheel drive side and detects torque on the front wheel side. The torque sensor 10 is provided with a transmission 9 on the rear wheel drive side. Is mounted between the speed change mechanism 8 and the differential mechanism 11 to detect the torque on the rear wheel side. The control device 6 controls the shift solenoid 3 of the automatic transmission 1 by judging the shift speed according to the running conditions, and controls the output of the motor 7 by inputting the detected torque of the front and rear wheels from the torque sensors 4 and 10. The shift start is determined from the control signal of the shift solenoid 3 and the shift period is determined. During the shift period,
The output of the motor 7 is controlled so that the total value of the detected torques of the front and rear wheels becomes the same as before the shift. That is, when the shift solenoid 3 is controlled by a signal from the control device 6 and the automatic transmission 1 starts shifting, the torque changes on the front wheels with the engagement and disengagement of the friction engagement device, thereby driving the entire vehicle. When the output of the motor 7 is controlled by the control device 6 so that the front wheel side torque fluctuation is absorbed by the rear wheel side, the driving force of the entire vehicle becomes constant. Shift shock can be reduced. FIG. 2 shows another embodiment of the driving force control apparatus for a hybrid vehicle according to the present invention. In the example shown in FIG. 2, the torque sensors 15 to 18 are attached to the axles of the front and rear wheels, and the rear wheels are independently driven by two motors 20 and 21 via transmissions (or reduction gears) 19 and 21 respectively. It is configured to be driven. FIG. 3 shows an example in which a control device corresponding to the above embodiment is configured by a plurality of blocks, and FIG. 3A corresponds to the control device 6 in FIG. FIG. 2B corresponds to the control device 14 shown in FIG.
If the rear wheel (right) control device 34 and the rear wheel (left) control device 35 are configured separately as in the latter case, the left and right torques are set separately according to the driving conditions, and the left and right rear wheels are controlled by two motors. Can be independently controlled. By doing so, it is possible to control so as to absorb not only the torque of the front wheel driven by the engine but also the fluctuation of the other torque of the rear wheel, and for example, the slip of the inner wheel during turning can be prevented. In other words, when turning, the centrifugal force reduces the ground contact load on the inner wheel side, making it easier to slip.However, by detecting the change in torque at this time, the torque on the outer wheel side can be used as a shoulder to prevent slip and prevent cornering during cornering. Acceleration can also be improved. Next, the flow of processing by the control device will be described with reference to FIG. First, the front wheel torque and the rear wheel torque are read, and the driving force is set based on the accelerator opening to control the output of the motor. The sum of the front wheel torque and the rear wheel torque at this time is defined as the pre-shift torque, and the shift signal (signal of the shift solenoid) is checked to determine whether or not the shift has started. If NO, the above processing is repeated. However, in the case of YES, the front wheel torque is read, and the difference between the pre-shift torque and the front wheel torque is set as the target value of the rear wheel torque to control the output of the motor. This process is performed until the shift is completed. In this case, the end of the shift is determined based on whether a predetermined time has elapsed from the start of the shift. It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, the start of the shift is determined by the shift signal, and the end of the shift is determined by the lapse of time after the start of the shift, but whether the torque on the engine drive side or the change amount (differential amount) is within a certain value. The determination may be made based on the above. Further, although the configuration in which the front wheels are driven by the engine is shown, the configuration may be such that the front wheels are driven by a motor, or the front wheels or the rear wheels that are the driving wheels of the two-wheel drive vehicle are hybrid-driven by the engine and the electric motor. It may be configured as follows. Further, the motor driving force detecting means may be substituted by detecting a motor driving command value such as a driving current, or detecting a change in the engine driving force from a change in the engine speed, and detecting the driving force of the motor. May be configured to calculate the correction value. As is clear from the above description, according to the present invention, a hybrid configuration in which one of the front wheels or the rear wheels is driven by the engine and the other is independently driven by the electric motor, and the fluctuation of the engine drive side torque during the gear shift period. Is compensated for on the motor drive side, so that the shift shock can be reduced by controlling the output of the motor without considering reduction of the shift shock in the automatic transmission on the engine drive side. Moreover, since the torque on the motor drive side is controlled, the configuration of the control device can be simplified without controlling the hydraulic circuit and the friction engagement device, and the burden on the automatic transmission can be reduced, and the automatic transmission can be reduced. Cost and reliability can be improved.
