TLDR
In this article, the starting condition of the control of distribution of the braking force is divided on the basis of the brake pedal depressing amount and speed or the like, and the judgement of a spike is set when the change is more than a specified value and a specified time has passed.Abstract:
PROBLEM TO BE SOLVED: To optimize the start of control of the distribution of the braking force by changing a threshold value on the basis of the depressing degree of a brake when the control of distribution of the braking force is started by controlling an inlet valve and an outlet valve of a rear wheel when the braking pedal is depressed and the estimated car deceleration or wheel deceleration is over the threshold value SOLUTION: The starting condition of the control of distribution of the braking force is divided on the basis of the brake pedal depressing amount and speed or the like (the change of estimated car deceleration or wheel deceleration), and the judgement of a spike (S21) A control start flag is set (S26) when the change is more than a specified value and a specified time has passed (the deressing is strong), and when the estimated deceleration is more than a specified value α1 as the result of the judgement whether the estimated deceleration is more than the specified value α or not (S22), and a slip ratio of a rear wheel is more than a specific value β1 (S23) The distribution control is started (S26) when the depressing is weak, the estimated deceleration is more than a specified value α2 as the result of the judgement whether the estimated deceleration is more than the specific value α2 (α2>α1) or not, and the slip ratio of the rear wheel to the front wheel is more than a specific value β2 (β2>β1) (S25) Whereby the starting time of the control of distribution of the braking force can be properly optimizedread more

Vehicle brake fluid pressure controller
TL;DR: In this article, a vehicle brake fluid pressure controller is described, which includes a normally open proportional solenoid valve provided in a hydraulic passage extending from a hydraulic pressure source to a wheel brake; a normally closed solenoids valve provided by the wheel brake and an antilock brake control module configured to suppress the locking of a wheel by performing a pressure increase control and a pressure decrease control.
