VEHICLE BRAKE HYDRAULIC PRESSURE CONTROL APPARATUS

摘要

A vehicle brake hydraulic pressure control apparatus includes a wheel speed acquiring section, a vehicle body deceleration calculator, and a switch section. The wheel speed acquiring section is configured to acquire a wheel speed from a wheel speed sensor. The vehicle body deceleration calculator is configured to calculate a vehicle body deceleration. The switch section is configured to switch control from the regenerative cooperation control to the hydraulic pressure control, based on (i) a wheel deceleration which is determined based on the wheel speed and (ii) the vehicle body deceleration. The vehicle body deceleration calculator is configured to calculate the vehicle body deceleration based on a required deceleration which corresponds to a driver's operation of a braking pedal.
