  • Publication number: 20200088527
    Abstract: An information processing device is provided capable of preventing tightening on a communication bandwidth due to an increase in communication amount. In the information processing device , a sensor data cache unit acquires a detection result from a sensor, and a position derivation unit and an object detection unit acquire host vehicle position/posture reliability information and object reliability information, respectively. The object detection unit next generates difference information on the basis of a high accuracy map and the object reliability information, and a transmission unit transmits the difference information. Then a confidence level generation unit generates a confidence level from the host vehicle position/posture reliability information and the object reliability information, and a data utilization determination unit determines whether or not to upload the difference information on the basis of the confidence level.

  • Publication number: 20180253105
    Abstract: Provided is an estimation device capable of estimating a current position with a high degree of accuracy. A driving support system includes: a vehicle mounted device 1 that is mounted on a vehicle and performs a control concerning vehicle driving support; a LIDAR 2; a gyroscope sensor 3; and a vehicle speed sensor 4. The vehicle mounted device 1 acquires, from the LIDAR 2, a measurement value ztk indicating a positional relationship between a reference landmark Lk of an index k and the own vehicle. The vehicle mounted device 1 calculates a post estimated value x?t by correcting a prior estimated value x t estimated, on the basis of the measurement value ztk and a position vector mk of the reference landmark Lk included in a map DB 10, from a moving speed measured by the vehicle speed sensor 4 and an angular rate measured by the gyroscope sensor 3.

  • Patent number: 8284223
    Abstract: A thermal printing mechanism includes a head unit having a heating element; an energizing unit that energizes the heating element; and an energizing control unit that controls the energizing unit to energize the heating element for a total energization time set according to a color density of a pixel so that the higher the color density is, the longer the total energization time becomes. The energizing control unit divides the total time period into energization time units, based on printing speed; specifies energization time units for energization so that a sum thereof is equivalent to the total energization time; and performs control so that if the printing speed is lower than a first printing speed, the energization time units appear continuous, and if the printing speed is equal to or higher than the first printing speed, the energization time units do not appear continuous.

  • Patent number: 8026938
    Abstract: When printing is performed by dividing a thermal printer head into segmented blocks, the number of dots to be printed in one line is changed, depending on the case, high-speed printing with a small division number of the segmented blocks, or low-speed printing with a large division number of the segmented blocks. When the division number of the segmented blocks is large and printing is performed at a low speed, paper feeding within one line is performed by multiple pitches to prevent the paper sheet from halting in one line, and energization is performed for each pitch to prevent occurrence of gaps between dots and between lines, by increasing the number of dots to be printed in one line. In the multiple pitches in one line, the ratio of energization amount to be fed in each pitch is changed to reduce a difference in density among pitches in one line.
