    摘要： The electric brake device includes an electric motor (4), a brake rotor, a friction pad, a conversion mechanism (6), a braking force command section (18a), a braking force estimation section (24), a controller (2), and a power supply device (30). The controller (2) includes: a power determination section (28) to determine whether an amount of remaining power that can be supplied from a power supply device (3) to the electric motor (4) has become equal to or less than a determined value; and a residual pressure cancellation section (29) to cancel a residual pressure of a braking force by driving the electric motor (4) in a direction opposite to a brake pressing direction such that an estimated value of the braking force obtained by the braking force estimation section (24) becomes equal to or less than a set value, when the power determination section (28) determines that the amount of remaining power has become equal to or less than the determined value.

    摘要： Since a speed reducer includes: a brake disk that is fixed to a rotationl shaft of a vehicle; permanent magnets that are disposed not only oppositely relative to a principal surface of the brake disk but also circumferentially in such a manner that each magnet is magnetized in reverse polarity to adjacent ones; a rotational member that retains the permanent magnets, has a switch brake disk, and is rotatably supported by the rotational shaft; a switch brake caliper that has brake pads sandwiching the switch brake disk therebetween, and is fixed to an irrotaional portion of the vehicle; and an electric linear actuator of a planetary roller mechanism that causes the brake pads to be linearly driven by converting rotational motion of the electric motor into linear motion, the speed reducer can realize a reduction in size, and thus can be installed even in a small- to mid-size vehicle not especially equipped with a compressed air tank or the like.

    摘要： An electric linear motion actuator is provided comprising a housing (1), an outer ring member (5), a rotary shaft (10) driven by an electric motor (11), a carrier (14) supported on the rotary shaft (10) and planetary rollers (21) mounted between the rotary shaft (10) and the outer ring member (5). The outer ring member (5) has a helical rib (6) formed on the radially inner surface of the outer ring member (5) and in engagement with circumferential grooves (24) formed on a radially outer surface of each of the planetary rollers (21). When the rotary shaft (10) rotates, the planetary rollers (21) are configured to rotate due to a frictional contact between the rotary shaft (10) of the planetary rollers (21), thereby moving the outer ring member (5) in an axial direction. The electric linear motion actuator further comprises a friction coupling means which is configured to frictionally fixedly couple the carrier (14) to the rotary shaft (10) while an axial load applied to the outer ring member (5) in a push-in direction is small, and to uncouple the carrier (14) from the rotary shaft (10) under the axial load when the axial load is large.

    摘要： A highly reliable vehicle brake system that includes an electric brake and achieves redundancy at low cost is provided.
    A vehicle brake system (1) includes electric brakes (16a to 16d) that include at least one unit of motors (80 and 81), and first and second control devices (10 and 11) that include a master controller (30) and a first sub-controller (40) that are connected to one another. The master controller (30) includes a driver control unit (301) that can control drivers (61 and 63), and a braking force calculation unit that calculates braking force of the electric brakes (16a to 16d). The first sub-controller (40) includes a driver control unit that controls a driver (60), and a braking force calculation unit that calculates braking force of the electric brakes (16a to 16d). The master controller (30) and the first sub-controller (40) include a determination unit that compares braking force calculation results of other controllers to determine braking force.
