Two-wheeled motor vehicle brake control method and brake control system
First Claim
1. A two-wheeled motor vehicle brake control method for a two-wheeled motor vehicle having an electronic control unit, said method comprising:
- using the electronic control unit to execute a program for detecting rear wheel lifting,reducing a pressure increase gradient of a wheel cylinder pressure of a front wheel when rear wheel lifting is no longer being detected,wherein reducing a pressure increase gradient does not start until after rear wheel lifting is no longer being detected and after landing of the rear wheel.

Abstract
To reliably prevent re-lifting of a rear wheel immediately after landing of the rear wheel.
When it is determined that output of a detection signal corresponding to detection of lifting of a rear wheel has ended (S102), brake pressure—and specifically a pressure increase gradient of a wheel cylinder pressure of a front wheel—is reduced, and the pressure increase gradient that has been reduced is maintained until it is determined that vehicle body deceleration has fallen below a predetermined value K1 (S108, S110), whereby re-lifting of the rear wheel caused by an increase in brake pressure at a high pressure increase gradient after landing of the rear wheel can be reliably prevented.

3. A two-wheeled motor vehicle brake control system configured to be capable of transmitting oil pressure arising in a front brake master cylinder in response to operation of a first brake operator to a front wheel cylinder via an oil pressure system, capable of transmitting oil pressure arising in a rear brake master cylinder in response to operation of a second brake operator to a rear wheel cylinder via an oil pressure system, and capable of discharging brake fluid of the front wheel cylinder to a front reservoir as desired,
wherein the brake control system is configured to determine whether or not output of a detection signal that is generated by detection of lifting of a rear wheel has ended and, when it is determined that output of the detection signal has ended, reduce a pressure increase gradient of a wheel cylinder pressure of a front wheel, wherein the brake control system is configured such that reducing a pressure increase gradient does not start until after rear wheel lifting is no longer being detected and after landing of the rear wheel.
