Filed: 2019-11-29
Abstract: To provide a travel controller capable of improving the accuracy in estimating a self position of a mobile body.SOLUTION: A position estimation part 11 estimates a self-position of a mobile body 2 based on results of detection by a laser sensor 3 and previously acquired map data. Consequently, the position estimation part 11 can compare objects detected by the laser sensor 3 and objects registered in the map data to each other to thereby estimate the self-position of the mobile body 2. Here, an object not registered in the map data may be included in the objects detected by the laser sensor 3. On the contrary, the position estimation part 11 specifies an obstacle not required for estimating the self-position among the objects and estimates the self-position based on the results of the detection excluding positional relation with the obstacle. Consequently, the position estimation part 11 can estimate the self-position of the mobile body 2 while avoiding erroneous recognition that the obstacle not required for estimating the self-position is an object registered in the map data.SELECTED DRAWING: Figure 1
