Publication number: US20210310452A1
Application number: 17/352,665

Abstract:
In a fuel injection device, a driving unit structure has a magnetic aperture, in which an inner diameter is gradually enlarged toward the mover side, provided in an inner peripheral surface of the magnetic core. It is possible to reduce magnetic delay time upon valve opening from the supply of the electric current to the coil to the rise of magnetic flux and magnetic delay time upon valve closing from the stoppage of the electric current to the coil to reduction of magnetic flux, by providing a magnetic aperture in the inner peripheral surface of the magnetic core. Thus it is possible to improve the dynamic responsiveness upon valve opening and valve closing.

Publication number: US20220001845A1
Application number: 17/283,914

Abstract:
An object of the present invention is to provide a brake control device and a brake system capable of braking with a shortened braking response when shifting from non-braking to braking. A brake control device 10 includes a command value calculation unit 4 that calculates an operation command value required to make a pressing force by which a brake pad 11a is pressed against a brake disc 11b reach a target thrust value. The command value calculation unit 4 includes: a clearance command calculation unit 43 that calculates a command value required for contact between the brake pad 11a and the brake disc 11b; and a thrust command calculation unit 40 that calculates a command value required for reaching the target thrust from a state where the brake pad 11a and the brake disc 11b are in contact with each other. When calculating the operation command value from a state where the brake pad 11a and the brake disc 11b are separated, the command value calculation unit 4 calculates the operation command value by integrating the command value calculated from the clearance command calculation unit 43 and the command value calculated from the thrust command calculation unit 40.

Publication number: US20210394752A1
Application number: 17/279,687

Abstract:
There is provided a traveling control device capable of appropriately performing collision avoidance by using not only a region inside a lane of an own vehicle but also a region outside the lane of the own vehicle. A traveling control device includes an acceleration calculation unit which obtains an acceleration of a target object from information of an outside recognition sensor, a behavior estimation unit which estimates a behavior of the target object from the acceleration, a TTC calculation unit which obtains a time to collision from the information of the outside recognition sensor, a determination unit which determines a risk region based on outputs of the TTC calculation unit and the behavior estimation unit, and a collision avoidance operation control unit which controls a collision avoidance operation for the target object based on a result of the determination unit.
