Embodiment Construction

[0022] Below, refer to Figure 1 ~ Figure 9B Embodiments of the present invention will be described. A travel control device according to an embodiment of the present invention is applied to a vehicle having an automatic driving function (autonomous driving vehicle). figure 1 It is a diagram showing a schematic configuration of a travel system of an autonomous vehicle 101 (which may be called an own vehicle to distinguish it from other vehicles) to which the travel control device of the present embodiment is applied. The vehicle 101 can travel not only in an automatic driving mode that does not require a driver's driving operation, but also in a manual driving mode that does not require a driver's driving operation.

[0023] Such as figure 1 As shown, a vehicle 101 has an engine 1 and a transmission 2 . The engine 1 is an internal combustion engine (such as a gasoline engine) that generates rotational power by mixing intake air supplied through a throttle valve 11 and fuel...

Abstract

A travel control apparatus (110) of a self-driving vehicle comprises an action plan generation part (45), which generates an action plan so as to utilize a vehicle detection part (31) to detect another vehicle as a target vehicle and make the self-driving vehicle follow the target vehicle; and a driving control part (46), which controls a driving action facility (1,2) that helps the self-driving vehicle according to the generated action plan. The action plan generation part (45) comprises a vehicle size recognition part (451), which recognizes the size of another vehicle detected by the vehicle detection part (31); a vehicle size determining part (452), which determines whether the difference between the size of the self-driving vehicle and the size of the recognized vehicle is greater than a predetermined value or not; and a target vehicle setting part (453), which determines the vehicles as the target vehicles if the difference between the vehicle sizes is lower than the predetermined value.

Description

technical field [0001] The invention relates to a driving control device of an automatic driving vehicle. Background technique [0002] A conventionally known device is a device for driving an autonomous driving vehicle to follow the vehicle ahead so that the inter-vehicle distance to the vehicle ahead is maintained at a set inter-vehicle distance. Such a device is described in Patent Document 1, for example. [0003] However, if the vehicle specifications of the own vehicle and the following vehicle are different, for example, the own vehicle may not be able to easily avoid an obstacle that the preceding vehicle can easily avoid, thereby hindering the following travel. [0004] prior art literature [0005] Patent Document 1: JP-A-2017-92678 (JP2017-092678A). Contents of the invention [0006] A technical solution of the present invention is a driving control device for an autonomous vehicle, which has: a vehicle detection unit that detects other vehicles around the ve...
