Braking force control apparatus

A braking force control apparatus controlling a regenerative generator in a vehicle in which a negative force with a traveling direction of the vehicle set to be positive is generated by at least a stepped automatic transmission and the regenerative generator,

• wherein the braking force control apparatus:
• predicts a time from a present time until a next start of a gear shift operation occurs in the stepped automatic transmission based on a speed of the vehicle;
• acquires a state of a battery charged by the regenerative power generation of the regenerative generator;
• and
• stops the regenerative power generation by the regenerative generator before the gear shift of the stepped automatic transmission is started, when it is determined, during the regenerative power generation by the regenerative generator, that the regenerative power generation by the regenerative power generator may be stopped due to the state of the battery during the gear shift operation of the stepped automatic transmission, based on the predicted time and the state of the battery,
• wherein predicting the time from the present time until the next stop of the regenerative power generation by the regenerative generator occurs due to the state of the battery based on a power storage rate or a charge current integrated value as the state of the battery, and determining that the regenerative power generation by the regenerative generator may be stopped due to the state of the battery during the gear shift operation of the stepped automatic transmission, when the predicted time is not less than the time until the gear shift operation is started in the stepped automatic transmission, and when the predicted time is not more than a time obtained by adding a predetermined period of the gear shift operation to the time until the gear shift operation is started.
