Patent number: 9073525Abstract: In a brake apparatus, an activation current for opening a simulator cut valve from a closed state is applied, whereupon a steady-state current is applied continuously to maintain the open state. A brake control apparatus and a brake control method are employed to perform control in which a valve opening current, which is higher than the steady-state current, is applied to the simulator cut valve every time a brake pedal is depressed. Thus, in a brake apparatus including a switch valve that is driven steadily by applying the steady-state current thereto, favorable control responsiveness can be maintained in the switch valve at all times while achieving a reduction in power consumption.Type: GrantFiled: July 18, 2008Date of Patent: July 7, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tsukasa Fukasawa, Takahiro Okano, Daisuke Nakata, Eiji Nakamura

Patent number: 8894159Abstract: In a brake controlling device (20), a separating valve (60) is provided in a main flow path (45) for interconnecting a first liquid pressure circuit and a second liquid pressure circuit. When an abnormality detecting section detects an abnormality relating to brake fluid pressure, a controlling section sets the separating valve (60) to a closed state. A leakage suppressing section performs leakage suppressing processing for suppressing entry of a brake fluid, which is in the first liquid pressure circuit, into the second liquid pressure circuit after the separating valve (60) is set to the closed state. A leakage suppressing section sets a master cut valve (64) to a closed state to perform the leakage suppressing processing.Type: GrantFiled: March 25, 2009Date of Patent: November 25, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Daisuke Nakata, Tsukasa Fukasawa, Eiji Nakamura, Takahiro Okano

Patent number: 8303046Abstract: There is provide a brake control technology according to which a target hydraulic pressure is reliably achieved when a hydraulic pressure is decreased during hydraulic control and brake drag does not occur even when the target hydraulic pressure is zero. In a brake apparatus, a dead-band region is set for the target hydraulic pressure that is used in the hydraulic control.
