One aspect of the invention relates to controlling the ammonia feed rate to an SCR reactor using a NOx sensor cross-sensitive to ammonia. The sensor, positioned downstream of the reactor, is interrogated by introducing a pulse in the ammonia feed rate. A positive response to a positive pulse indicates ammonia slip. A negative response to a positive pulse indicates NOx breakthrough. Another aspect of the invention related to a combination of feed-back and feed-forward control. Upon detecting ammonia slip, the controller enters into an ammonia slip recovery mode in which the ammonia feed rate is reduced for a period to restore the reactor's ammonia or NOx buffering capacity. After the recovery period, feed-forward control is restored, optionally with an updated control objective. A further aspect of the invention relates to a learning probabilistic model for feed-forward control trained according to the occurrence or non-occurrence of NOx breakthrough and ammonia slip.

An SOC target is a control target of a remaining capacity of an accumulation device having a characteristic that the internal loss increases in a low SOC region. The SOC target is set to a first value corresponding to a remaining capacity target upon reaching a predetermined point when the remaining travel distance up to a predetermined point where the accumulation device can be charged from outside has become shorter than a predetermined distance. Thus, the hybrid vehicle can perform EV travel by power consumption of the accumulation device. On the other hand, when the remaining travel distance is not smaller than the predetermined distance Dr, the SOC target is set to a second value in the SOC region where the loss of the accumulation device is smaller than the first value. Thus, it is possible to reduce the power consumption in the hybrid vehicle which performs such a remaining capacity management that the remaining capacity of the accumulation device upon arrival at a predetermined point is a predetermined value.

An error output controller controls the output of the error values detected by the error detector in accordance with the state of the flag information generated by the generator.

This invention relates to a transmission power control method and transmission power control apparatus in a mobile communication system. The reception quality of a signal (31, 32a, 32b, 41, or 42) transmitted from another mobile station (51 or 52) or base station (21 or 22) is compared with a predetermined control target value such as a signal-to-interference ratio. The comparison result is used for transmission power control on a remote station. If a frame error is detected in a transmitted signal, the control target value is increased by SIRinc. If no frame error is detected, the control target value is decreased by SIRdec. As SIRdec, the product of a target value of a frame error rate and SIRinc is set. With this operation, when a propagation environment such as multibus or moving speed changes, the control target value for transmission power control is changed within a short period of time, and channel quality is maintained constant, thus realizing desired channel quality.
