  • Publication number: 20160325738
    Abstract: A vehicle configured to suppress a variation in a deceleration during braking. When a regeneration braking force is generated by a hybrid ECU to brake a hybrid vehicle, and an abnormality occurs to communication between the ECU and a brake ECU, the ECU gradually decreases a magnitude of a target regeneration braking force as the time elapses. On the other hand, the ECU gradually increases a magnitude of a target friction braking force up to a magnitude of a target total braking force as the time elapses. Further, when the vehicle is braked, and power supply to the ECU is shut off to result in an abnormality in the communication between the ECU and the ECU, the ECU finishes the regeneration operation of an electric motor, and the ECU rapidly increases the magnitude of the target friction braking force to the magnitude of the target total braking force.

  • Publication number: 20160319323
    Abstract: A method for detecting a site which can be modified with an N-linked glycan chain and to which an N-linked glycan chain is actually linked in a glycoprotein; and a method for determining the state of an N-linked glycan chain addition at the site are provided. A glycoprotein having an N-linked glycan chain linked thereto is subjected to an N-linked glycan chain removal treatment with a peptide N-glycanase, subsequently a site capable of being modified with an N-linked glycan chain, in which an Asn residue has been changed to an Asp residue by the action of the peptide N-glycanase, is treated with an endo-type peptidase capable of recognizing an Asp residue to thereby produce peptide fragments, and subsequently the mass of the fragments is detected. In this manner, a site which can be modified with an N-linked glycan chain and to which an N-linked glycan chain is actually linked can be detected.

  • Patent number: 9073525
    Abstract: 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.

  • Patent number: 8931856
    Abstract: 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).

  • Patent number: 8894159
    Abstract: 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.
