Braking control apparatus for hybrid vehicle

A braking control apparatus for a hybrid vehicle, the hybrid vehicle including a power unit that has an engine and a motor generator, the engine and the motor generator serving as drive sources of the power unit, the braking control apparatus comprising:

• a braking force control unit configured to perform a braking force control by coordinating an engine brake using the engine, a regenerative brake using the motor generator, and a friction brake using a friction engagement member;
• a first abnormality detecting unit configured to detect an abnormality in the regenerative brake;
• a second abnormality detecting unit configured to detect an abnormality in (1) a wheel speed sensor of the hybrid vehicle or (2) a longitudinal acceleration sensor of the hybrid vehicle;
• a regenerative brake stopping unit configured to disconnect the regenerative brake from the braking force control and stop an activation of the regenerative brake, in a case where the abnormality in the regenerative brake is detected by the first abnormality detecting unit;
• and
• a braking force compensating unit configured to perform a braking force compensation that utilizes the friction brake, during a time period from when the abnormality in the regenerative brake is detected by the first abnormality detecting unit to when the regenerative brake is disconnected from the braking force control by the regenerative brake stopping unit,
• wherein the braking force compensating unit is configured to perform the braking force compensation by performing a feedback control based on a deceleration rate at a time when the abnormality in the regenerative brake is detected by the first abnormality detecting unit, and
• wherein the braking force compensating unit is configured to perform the braking force compensation by applying a preset constant brake fluid pressure to the friction brake, in place of performing the feedback control, at least in a case where:
• the abnormality in the regenerative brake is detected by the first abnormality detecting unit;
• and the abnormality in the wheel speed sensor or the longitudinal acceleration sensor is detected by the second abnormality detecting unit.
