<p>PROBLEM TO BE SOLVED: To improve accuracy of detecting a relative speed.SOLUTION: A travel control device for controlling traveling of a movable body on the basis of a relative speed to a preceding vehicle includes: a relative-speed arithmetic processing unit calculating a first relative speed by differentiating an inter-vehicle distance to the preceding vehicle detected by a sensor; a low-pass filter performing a low-pass filter process on the first relative speed; and a high-pass filter performing a high-pass filter process on a second relative speed to the preceding vehicle detected by the sensor; and a convolution arithmetic processing unit performing a convolution arithmetic process between the first relative speed subjected to the low-pass filter process by the low-pass filter and the second relative speed subjected to the high-pass filter process by the high-pass filter. A movable body travel control is executed on the basis of an arithmetic result of the convolution arithmetic processing unit.</p> |
