    Abstract: A vehicle control system includes an integration unit that estimates information on a position and a speed of a target existing in an external field and errors of the position and the speed of the target, based on information from a movement sensor that acquires movement information including a vehicle speed and a yaw rate of an own vehicle, and information from an external field sensor that acquires information on the external field of the own vehicle. The integration unit uses not the information from the external field sensor, but the vehicle speed and the yaw rate acquired by the movement sensor, to predict a position and a speed of the target and errors of the position and the speed of the target at a second time after a first time, from a position and a speed of the target and errors of the position and the speed at the first time.

    Abstract: Provided is a control device to be used for a vehicle including: a steering wheel configured to steer the vehicle; a steering member configured to steer steered wheels in accordance with rotation of the steering wheel; and a steering actuator configured to apply a steering force to the steering member, the control device including a control unit configured to output, to the steering actuator, a drive signal for applying the steering force based on steering information on the steering wheel. The control unit is configured to output, to the steering actuator, a drive signal for reducing the steering force until the steering member reaches a stroke end after a rotation angle of the steering wheel reaches a predetermined control start angle and increasing the steering force when the steering member reaches the stroke end and then bounces back.

    Abstract: When a pilot valve is actuated, and an actuating rod to which a valve body is fixed moves in an axial direction, hydraulic liquid of an equivalent amount to a volume of a portion of the actuating rod which enters and retracts from a valve body back-pressure chamber moves between a pilot chamber and the valve body back-pressure chamber through an orifice (volume compensation). At this time, the damping that is generated by the hydraulic liquid passing through the orifice acts on the valve body, which restrains self-induced vibrations (chattering) of the pilot valve.

    Abstract: When it is assumed that a large-scale Deep Neural Network for autonomous driving applied compression, there are problems of a decrease in recognition accuracy of a post-compression Neural Network (NN) model and an increase in a compression design period, due to a large number of harmful or unnecessary training images (invalid training images). A training image selection unit B100 calculates an influence value on an inference, and generates an indexed training image set 1004-1 necessary for an NN compression design, by using the influence value. A neural network compression unit P200 notified of the result via a memory P300 compresses the NN.

    Abstract: In a variable displacement oil pump (VP1) according to the present invention, a coil spring (SP) as an urging member is arranged at a position that does not overlap a first suction port (114), a first discharge port (115) and an inlet (124a) which correspond to a suction portion when viewed from an axial direction along a drive shaft (2). Therefore, in the variable displacement oil pump (VP1), there is no risk that during pump operation, flow of oil introduced into the pump chambers 30 located in a suction region through the first suction port (114), the first discharge port (115) and the inlet (124a) corresponding to the suction portion will be interrupted by the coil spring (SP). With this, in the variable displacement oil pump (VP1), a suction resistance during the pump operation is reduced, then a suction performance of the pump can be improved.

    Abstract: A stereo camera apparatus includes a housing, a first camera unit attached to the housing, a second camera unit attached to the housing, a processing device that performs image processing by using captured images acquired by capturing of the first camera unit and the second camera unit, and a circuit board on which the processing device is mounted. In the housing, a base length direction of the first camera unit and the second camera unit is a longitudinal direction, the housing and the circuit board are bonded to each other by an adhesive, and in a region in the housing, onto which the adhesive is applied, a length in the base line length direction is shorter than a length in an orthogonal direction that is a direction perpendicular to the base length direction.

    Abstract: In a variable displacement oil pump (VP1) according to the present invention, a stopper portion (45) that can come into contact with a cam ring contact portion (112e) provided at a pump accommodating portion (110) is provided at a position that does not overlap a first suction port (114), a second suction port (124) and an inlet (124a), which correspond to a suction portion, in a circumferential direction of rotation of a drive shaft (2) on a rotation center (Z). Therefore, there is no risk that flow of oil sucked into pump chambers (30) located in a suction region through the first suction port (114), the second suction port (124) and the inlet (124a) will be interrupted by the stopper portion (45), thereby improving a suction performance of the pump.
