Therefore, the map A is selected as the map of the T-N characteristic in the normal driving state, and this map A is used for the output of the torque command.
- map B is selected (S 2 2). This state is when the user desires low fuel consumption driving when the vehicle travels. At this time, it is not necessary to consider braking. Therefore, for map B, a map that limits the upper limit of the torque is selected rather than the T-N characteristic in the normal traveling state, and for torque command output, map B that has performed this torque limitation is selected. Used. When the sign of the required torque 46 is negative, the map C is selected regardless of whether the eco switch 48 is on or off (S 24). This state is when the vehicle is braked. Since Ecositch 4 8 is not related to whether it is on or off, the TN characteristic map for normal braking can be used.
- the T-1N characteristic map in the case of normal braking is obtained by inverting the sign of torque from the map A, which is the T-1N characteristic map in the case of normal braking.
- FIG. 3 is a diagram for explaining the contents of Map A, Map 3, and Map C.
- the horizontal axis in FIG. 3 is the rotational speed N of the motor Z generator 22, the vertical axis is the output torque of the motor / generator 22 2, and the signs are positive and negative.
- Figure 3 shows three T-N characteristics.
- the first T-N characteristic 60 is shown in the positive part of the vertical axis and corresponds to map A.
- the second T-N characteristic 70 is shown in the positive part of the vertical axis, but the maximum torque is limited compared to the T-N characteristic 60 of map A, and the torque is smaller as a whole. .
- the T-N characteristic 60 of map A is a T-N characteristic with a torque limit applied, and this corresponds to the T-N characteristic of map B.
- the third T-N characteristic 80 is shown as an inverted version of the T-N characteristic 60 of map A with respect to the horizontal axis because the vertical axis is shown in the negative part. This corresponds to the TN characteristic of map C.
- Map A's T_N characteristic 60 is the T-N characteristic of a normal carousel.
- the constant torque 6 2 is set due to the current limitation, and in the region where the rotation speed N is large, the maximum rotation speed 64 is set due to the limitation of the maximum vehicle speed.
- the T-N characteristic 70 of map B is the maximum torque compared to the TN characteristic 60 of map A in order to reduce fuel consumption when the eco-switch 4 8 is turned on in the coasting state as described above.
- the torque is limited and the torque is limited. Therefore, Ekosi
- the torque value is lowered to the value of the T-N characteristic 70 of Map B, and the torque value is low.
- the torque value is output to the drive unit 20 as a torque command.
- the torque value at point Y is used as the torque command value.
- the T-N characteristic 70 of map B is limited on the maximum torque than the T-N characteristic 6 0 of map A, which is used for normal power.
- the maximum torque is limited to the torque value, which achieves low fuel consumption.
- the T-N characteristic 80 of map C is obtained by inverting the TN characteristic 60 of map A with respect to the horizontal axis as described above. The same T-N characteristic 80 of map C is used when eco-switch 48 is off and on.
- FIG. 4 is a diagram showing an example in which the TN characteristic of map B is realized by changing the step-up ratio of voltage converter 30.
- the step-up ratio of the voltage converter 30 is normal, and the T characteristics N 1 in the normal running state and the low voltage T 1 when the step-up ratio of the voltage converter 30 is arbitrarily reduced.
- N characteristic 7 2 and voltage converter 30 step-up ratio 1, that is, no voltage is boosted at all, and the voltage of power storage device 26 is directly applied to inverter / generator circuit 2 through inverter circuit 3 6
- No-boosting TN characteristics 7 4 in the case of supply to Even in this case, the TN characteristic 80 of map C is not changed in the same way as described in FIG.
- the regenerative power is effective during regeneration. The maximum recovery can be achieved.
- the required torque is indicated by the Z point.
- the maximum torque is limited by the T-N characteristic 6 0 of map A, so the torque value at point Z is not limited, and the value of required torque 4 6 is the torque as it is. Output as command value.
- the eco switch 48 is turned on, the step-up ratio of the voltage converter 30 is changed so that the TN characteristic 72 passing through the point Z is obtained.
- the drive part 20 act operates with the pressure increase ratio. Therefore, by changing the step-up ratio, the maximum torque is limited more than the T-N characteristic 60 of map A when the vehicle is running normally, thereby realizing low fuel consumption.
- the T-N characteristic 72 passing through the point Z can be obtained by searching from the TN characteristic stored in the storage device 44 using the torque value and the rotation speed at the point Z as search keys.
