This braking control device feeds by pressure a braking fluid from a master cylinder to a wheel cylinder, to generate a braking force in a wheel. The braking control device is provided with an input rod; an output rod; first and second electric motors; and first and second racks forming a differential mechanism. When the outputs of the first and second electric motors are controlled, the operation power of the input rod and the displacement of the output rod are controlled independently of each other. Here, in the second rack, the movement, in a backward direction, in response to decrease of a master cylinder fluid pressure is limited within a range of a predetermined displacement by means of two stoppers.

A method of detecting brake fade for a vehicle brake system having wheel brakes susceptible to brake fade, includes the steps of: (a) providing a brake system including wheel brakes; and (b) determining the presence of brake fade within the vehicle system utilizing adaptive references maps, and wherein the adaptive reference maps include storing vehicle deceleration data and brake system fluid volume at different pressure points in a histogram.

An electric brake device installed on a vehicle, including: a rotary body to rotate with a wheel; a friction member to be pushed onto the rotary body; an actuator including an electric motor as a drive source to cause the friction member to be pushed onto the rotary body; and a controller to control a braking force generated by the electric brake device by controlling a supply current supplied to the electric motor, wherein the controller determines, by mutually different methods, a plurality of target supply current components each of which is a component of a target supply current as a target of the supply current, determines the target supply current by adding up the target supply current components, and changes contribution degrees of the respective target supply current components in the determination of the target supply current in accordance with a characteristic of the braking force to be generated.

A main ECU controls a braking force by driving an electric motor of a brake mechanism based on a value detected by a thrust force sensor provided to the brake mechanism. The main ECU calibrates (corrects) the value detected by the thrust force sensor based on a driving force acquired when, while a driving force is applied to left and right front wheels serving as driving wheels with the braking force applied to a rear right wheel or a rear left wheel by the brake mechanism, this driving force exceeds the braking force.

A parking mechanism that includes a wheel disc, a wedge disc, and a drive assembly. An axis of the wheel disc and an axis of the wedge disc both are aligned with an axis of a motor shaft. A wedge groove with an opening facing the wheel disc is formed on a surface of the wedge disc facing the wheel disc, and a movable part in contact with the wheel disc is disposed in the wedge groove. In a direction from a bottom of the wedge groove to the wheel disc, a groove depth at a first end of the wedge groove is greater than a size of the movable part, and a groove depth at a second end of the wedge groove is less than the size of the movable part. The parking mechanism can provide stepless variable parking force.

The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.
