Title:
BRAKE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/031106
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable stable braking without being affected by age-related deterioration of a brake device or the like. The brake ECU 30 of a vehicle 1 has a brake device 11 capable of adjusting the braking force according to supplied hydraulic pressure. The vehicle 1 is provided with a master pressure sensor 17 for measuring the hydraulic pressure supplied to the brake device 11, and a G sensor 44 and wheel speed sensor 12 for measuring acceleration information whereby the acceleration of the vehicle 1 can be detected. The brake ECU 30 is configured so as to comprise a pressure command value calculation section 36 that determines, on the basis of a preset coefficient, the hydraulic pressure to be supplied to the brake device 11 at the time of deceleration of the vehicle 1 and supplies the determined hydraulic pressure to the brake device 11, and a brake torque coefficient calculation section 31 that, on the basis of the relationship between the hydraulic pressure and acceleration, learns a candidate coefficient serving as a candidate in changing the coefficient and changes the coefficient to the candidate coefficient.
