Publication number: 20110285198Abstract: 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. When braking control is switched from the hydraulic control to regenerative control in cooperative braking control, residual pressure reduction control is executed. In the residual pressure reduction control, the target hydraulic pressure is set to a value that is lower than zero to which the hydraulic pressure should be brought.Type: ApplicationFiled: August 8, 2008Publication date: November 24, 2011Applicant: Toyota Jidosha Kabushiki KaishaInventors: Daisuke Nakata, Takahiro Okano, Tsukasa Fukasawa

Publication number: 20100270854Abstract: A brake control apparatus obtains a required braking force using a hydraulic braking force in combination with a regenerative braking force. The brake control apparatus includes a hydraulic brake unit that controls the hydraulic braking force. When the deviation of an actual hydraulic pressure from a target pressure falls outside a permissible range (d), the hydraulic brake unit controls the actual hydraulic pressure in such a manner that the deviation falls within the permissible range. On the other hand, when the deviation is within the permissible range (d), the hydraulic brake unit maintains the actual hydraulic pressure. The hydraulic brake unit includes a control unit that detects timing (Ta) at which usage of the hydraulic braking force needs to be started to compensate for a deficiency from the required braking force, and that raises (r) the target pressure at the detected timing (ta).Type: ApplicationFiled: December 23, 2008Publication date: October 28, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takahiro Okano, Daisuke Nakata

Publication number: 20100219026Abstract: 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: ApplicationFiled: July 18, 2008Publication date: September 2, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tsukasa Fukasawa, Takahiro Okano, Daisuke Nakata, Eiji Nakamura

Publication number: 20100211282Abstract: In a brake control apparatus that controls braking forces which are applied to wheels based on the pressure of the hydraulic fluid, when the pressure detected by a control pressure sensor (73) is equal to or higher than a predetermined value while a partition valve (60) is closed, a master cut valve (64) is closed to suppress an increase in the pressure in a first passage (45) in a first hydraulic circuit (37), to which the control pressure sensor (73) is connected. Alternatively, the control pressure sensor (73) is protected against overpressure by opening the outlet valve (56,57) or the pressure-decreasing valve (67).Type: ApplicationFiled: July 16, 2008Publication date: August 19, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daisuke Nakata, Takahiro Okano
