Title:
TRAVEL CONTROL DEVICE, TRAVEL CONTROL METHOD, AND TRAVEL CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/074640
Kind Code:
A1
Abstract:
Provided is a travel control device that executes a coasting process, a cruising process, a gradient information acquisition process (S72, S72a), a deviation variable acquisition process (S74, S74a, S86), and a switching process (S62). The coasting process causes a vehicle to coast. The cruising process keeps the speed of the vehicle at a set speed while giving priority to meeting a certain condition. The certain condition defines that when a preceding vehicle exists within a prescribed range in front of the vehicle, the distance to the preceding vehicle is maintained within a predetermined range. The gradient information acquisition process acquires gradient information about the road surface on which the vehicle is traveling. The deviation variable acquisition process acquires a deviation variable, independently of the gradient information, that specifies the acceleration that is generated on the vehicle when the vehicle travels through the coasting process on a downhill slope having a predetermined gradient. The switching process inputs the gradient information and the deviation variable and includes: a process for switching to the coasting process when the vehicle travels on a downhill slope while the cruising process is being executed; and a process for switching to the coasting process when the magnitude of the gradient is different according to the value of the deviation variable.
