The invention discloses a brake feedback system, a vehicle and a control method of the brake feedback system. A brake pedal (100) of the brake feedback system is connected with a first piston (201), the brake pedal (100) pushes the first piston (201) to move when moving under the action of braking force, brake fluid in a second hydraulic cavity (202) enters a first hydraulic cavity (302), a second piston (301) moves to compress brake fluid in a third hydraulic cavity (303), and the brake fluid in the third hydraulic cavity (303) applies hydraulic force to a first control valve (500); when the hydraulic pressure is larger than or equal to the target hydraulic pressure of the first control valve (500), the first control valve (500) is opened, and the brake fluid enters the oil pot (400). When a driver applies a braking force to a brake pedal (100), a target hydraulic force of a first control valve (500) is adjusted by a controller, thereby adjusting a hydraulic force in a pedal feeling simulator (300), and further adjusting a feedback force fed back to the brake pedal (100).

    公开了一种制动反馈系统、车辆及制动反馈系统的控制方法。制动反馈系统的制动踏板(100)与第一活塞(201)连接,制动踏板(100)在制动力作用下运动时推动第一活塞(201)运动,第二液压腔(202)中的制动液进入第一液压腔(302),第二活塞(301)运动以压缩第三液压腔(303)中的制动液,第三液压腔(303)中的制动液向第一控制阀(500)施加液压力;当液压力大于或等于第一控制阀(500)的目标液压力时,第一控制阀(500)打开,制动液进入油壶(400)。当驾驶员对制动踏板(100)施加制动力时,通过控制器调节第一控制阀(500)的目标液压力,从而调节踏板感觉模拟器(300)中的液压力,进而调节反馈至制动踏板(100)的反馈力。
