Title:
SPEED CALCULATION DEVICE, CONTROL METHOD, PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2017/094065
Kind Code:
A1
Abstract:
According to the present invention, when it has been determined that a lidar-based vehicle body speed VL can be calculated, a control unit 15 calculates the lidar-based vehicle body speed VL as an estimated vehicle body speed VE and performs calibration processing on a transformation coefficient K, a sensitivity coefficient A, and an offset coefficient B. When it has been determined that the lidar-based vehicle body speed VL cannot be calculated, the control unit 15 uses the newest calibrated transformation coefficient K, sensitivity coefficient A, and offset coefficient B to calculate each of an axle-pulse-based vehicle body speed VP and an acceleration-based vehicle body speed Vα and calculates the estimated vehicle body speed VE by performing weighting that corresponds to the reliability of said calculated values.
