TLDR
In this article, the tentative target hydraulic braking torque is determined based on the total required braking torque and the actual regenerative braking torque by S18-S22, the sharing gradient from the regenerative brake to the hydraulic brake is acquired based on deceleration or the like of a vehicle body by S24, and the control delay correction is performed to determine the target hydraulic brake torque.Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular braking system capable of suppressing fluctuation of the total braking torque when the braking torque applied to a wheel by a regenerative brake is shared by a hydraulic brake. SOLUTION: In a vehicular braking system to brake a vehicle through the cooperative control of a regenerative brake with a hydraulic brake, the tentative target hydraulic braking torque is determined based on the total required braking torque and the actual regenerative braking torque by S18-S22, the sharing gradient from the regenerative brake to the hydraulic brake is acquired based on the deceleration or the like of a vehicle body by S24, and the control delay correction is performed to the tentative target hydraulic braking torque by S26-S36 to determine the target hydraulic braking torque. In S38, the braking torque of the hydraulic brake is increased in a leading manner, and the hydraulic pressure follow-up regenerative control is performed, in which the regenerative braking torque is reduced while the total required braking torque is excessive thereby.

Brake system of a rail vehicle with compensation of fluctuations of the friction conditions
TL;DR: In this paper, a sensor device is used to measure the time profile of at least one variable, representing fluctuations in the friction conditions between the wheel or wheel set assigned to the brake actuator and the rail and/or between the brake disk assigned to a brake disk and the brake lining, and to output a signal dependent on the measured variable to a control device which adapts the braking force generated by the Brake actuator as a function of the deviation of the time profiles of the variable from a predefined or expected time profile.
