Vehicle brake hydraulic pressure control apparatus

摘要

One embodiment provides a vehicle brake hydraulic pressure control apparatus configured to perform a pressure hold control to hold a brake hydraulic pressure in a state in which a vehicle comes to a halt. Further, the pressure hold control is canceled using an initial pressure reduction mode in which the brake hydraulic pressure is reduced at one of a rapid pressure reduction rate of a previously-set given gradient and a normal pressure reduction rate calculated based at least on an accelerator opening, which is higher and a latter pressure reduction mode in which the brake hydraulic pressure is reduced at the normal pressure reduction rate after the brake hydraulic pressure has been reduced to a switching threshold by the initial pressure reduction mode.

1. A vehicle brake hydraulic pressure control apparatus configured to perform a pressure hold control to hold a brake hydraulic pressure in a state in which a vehicle comes to a halt,
wherein the pressure hold control is canceled using:
an initial pressure reduction mode in which the brake hydraulic pressure is reduced at one of a first pressure reduction rate of a previously-set given gradient and a second pressure reduction rate calculated based at least on an accelerator opening, whichever is higher; anda latter pressure reduction mode in which the brake hydraulic pressure is reduced at the second reduction rate after the brake hydraulic pressure has been reduced to a switching threshold by the initial pressure reduction mode, and further comprising comparing the second pressure reduction rate and the first pressure reduction rate to determine which is higher.
