and a battery running inhibiting portion that inhibits the hybrid vehicle from running in the first running mode when it is determined by the transport state determining portion that the hybrid vehicle is in transport. ## Claims ### Claim 1 A hybrid vehicle running control apparatus that is mounted in a hybrid vehicle that has a high-voltage battery and a low-voltage battery, and is selectively controlled to drive in a first running mode in which an electric motor to which power is supplied from the high-voltage battery is used as a drive source, and a second running mode in which an engine is used as the drive source, the hybrid vehicle running control apparatus comprising: an ECU configured to determine whether the hybrid vehicle is in transport; and inhibit the hybrid vehicle from running in the first running mode when the hybrid vehicle is determined to be in transport. ### Claim 2 (depends on 1) The hybrid vehicle running control apparatus according to claim 1, wherein the ECU is configured to prohibit the hybrid vehicle from running in the first running mode when the hybrid vehicle is determined to be in transport. ### Claim 3 (depends on 1) The hybrid vehicle running control apparatus according to claim 1, wherein the ECU is configured to shift a threshold used to select / deselect the first running mode to a side on which the first running mode is not as easily selected, when the hybrid vehicle is determined to be in transport, compared to when the hybrid vehicle is determined to be not in transport. ### Claim 4 (depends on 1) The hybrid vehicle running control apparatus according to claim 1, wherein the ECU is further configured to charge the low-voltage battery by supplying power to the low-voltage battery from the high-voltage battery, each time a parked time of the hybrid vehicle reaches a predetermined period of time. ### Claim 5 (depends on 4) The hybrid vehicle running control apparatus according to claim 4, wherein the ECU is configured to allow power to be supplied from the high-voltage battery and charge the low-voltage battery when a state-of-charge of the high-voltage battery is equal to or greater than a predetermined value. ### Claim 6 (depends on 1) The hybrid vehicle running control apparatus according to claim 1, wherein the ECU is further configured to make a charging voltage when charging the low-voltage battery higher when the hybrid vehicle is determined to be in transport, than when the hybrid vehicle is not determined to be in transport. ### Claim 7 (depends on 6) The hybrid vehicle running control apparatus according to claim 6, the hybrid vehicle further comprising: a voltage converter that performs a voltage conversion between the high-voltage battery and the low-voltage battery, wherein the ECU is configured to make an output voltage to the low-voltage battery from the voltage converter, as the charging voltage, higher when the hybrid vehicle is determined to be in transport, than when the hybrid vehicle is not determined be in transport. ### Claim 8 (depends on 1) The hybrid vehicle running control apparatus according to claim 1, further comprising: a fuse configured to be removed from a power supply line upon transport of the hybrid vehicle, and is attached to the power supply line after the transport is complete, wherein the ECU is configured to determine that the hybrid vehicle is in transport when a message from each electronic control unit under control of the fuse in the power supply line is not received. ### Claim 9 (depends on 8) The hybrid vehicle running control apparatus according to claim 8, wherein the ECU is configured to determines that the hybrid vehicle is in transport when a message from each of the electronic control units under control of the fuse in the power supply line is not received, and a message from an electronic control unit not under control of the fuse is received.
