Abstract: A vehicle braking control device includes first and second deceleration calculation units, an assist control unit, and a termination determination unit. The first deceleration calculation unit calculates a first estimated vehicle body deceleration using a wheel speed sensor detection signal. The second deceleration calculation unit calculates a second estimated vehicle body deceleration using a vehicle body acceleration sensor detection signal. The assist control unit initiates assist control, which assists increasing a braking force when the first estimated vehicle body deceleration exceeds a first deceleration determination value and the second estimated vehicle body deceleration exceeds a second deceleration determination value. The termination determination unit determines whether or not a termination condition of the assist control is satisfied based on at least one of the first and the second estimated vehicle body decelerations. The assist control unit terminates the assist control when it is determined that the termination condition is satisfied.

Abstract: A brake ECU determines whether or not interference-based vibration components are included in a vehicle body deceleration (DV) (steps S74, S76). Then, in the case of a positive determination (YES in step S74 or step S76), the brake ECU makes a comparison with when the determination is not positive, and revises a first deceleration determination value (DV_st) to be a larger value (step S79). If the vehicle body deceleration value (DV) exceeds the first deceleration determination value (DV_st) and a G sensor value (G) exceeds a second deceleration determination value (G_st) (YES in steps S84 and S89), the brake ECU initiates auxiliary control.

Abstract: A brake-pedal depression force estimation device includes: a first deceleration calculation unit which uses a vehicle-mounted wheel speed sensor to calculate a first estimated vehicle-body deceleration for the vehicle; a second deceleration calculation unit which uses a vehicle-mounted vehicle-body acceleration sensor to calculate a second estimated vehicle-body deceleration for the vehicle; a gradient acquisition unit which acquires the gradient of change for the first estimated vehicle-body deceleration; and a depression force determination unit which determines if the brake-pedal depression force applied by a driver is high or not. The gradient acquisition unit acquires a first gradient of change and a second gradient of change. The depression force determination unit is configured so as to determine the brake-pedal depression force applied by a driver to be high when the second gradient of change is equal to or exceeds the first gradient of change.

Abstract: A brake ECU acquires the vehicle load (WW) (step S142), and sets a higher start-time criterion value (KT2) when the load (WW) is heavy than when the load (WW) is light (step S144). The brake ECU initiates auxiliary control when the period since the deceleration of the vehicle exceeded a first deceleration determination value is less than or equal to the start-time criterion value (KT2) and the G sensor value exceeds a second deceleration determination value.
