Vehicle control apparatus

摘要

A vehicle control apparatus includes: a first braking force generating section configured to actuate, by a hydraulic pressure, wheel cylinders; a second braking force generating section configured to be mechanically regulated to provide the braking force to the one of the wheels; a braking force control switching section configured to automatically switch the second braking force generating section from a non-actuation state to an actuation state when a predetermined condition is satisfied in an actuation state of the first braking force generating section and in the non-actuation state of the second braking force generating section, and to switch the first braking force generating section to the non-actuation state; and a braking force characteristic control section configured to control a braking force characteristic generated by the first braking force generating section, and relating to the switching operation of the braking force control switching section.

1. A vehicle control apparatus comprising:
a first braking force generating section configured to actuate, by hydraulic pressure, wheel cylinders which are mounted on a vehicle, which are connected through hydraulic pipes with a master cylinder, and which are provided, respectively, to a plurality of wheels, and thereby to generate a braking force to the wheels; a second braking force generating section which is provided to one of the plurality of the wheels, and which is configured to be mechanically regulated to provide the braking force to the one of the plurality of wheels; a braking force control switching section configured to automatically switch the second braking force generating section from a non-actuation state to an actuation state when a predetermined condition is satisfied in an actuation state of the first braking force generating section and in the non-actuation state of the second braking force generating section, to decrease the hydraulic pressure of the first braking force generating section, and thereby to switch the first braking force generating section to the non-actuation state; and a braking force characteristic control section configured to control a braking force characteristic which is generated by the first braking force generating section, and is associated with switching of the braking force control switching section, wherein the braking force characteristic control section is configured to limit decrease gradients of hydraulic pressures of wheel cylinders provided to others of the plurality of the wheels to a value equal to or smaller than a predetermined gradient.
