Abstract

A driving control device of a vehicle includes a surrounding environment recognizer configured to recognize a surrounding environment of the vehicle, a travel controller configured to control acceleration and deceleration of the vehicle according to a driving mode, a mode setter configured to change the driving mode, and an operation detector configured to detect a brake pedal operation by an occupant. The driving mode includes a start standby mode in which the travel controller starts the vehicle according to the surrounding environment when the vehicle is stopped, and a stop maintenance mode in which the travel controller maintains a stopped state of the vehicle when the vehicle is stopped, and in a case where the driving mode is the start standby mode and the brake pedal operation is detected, the mode setter changes the driving mode from the start standby mode to the stop maintenance mode.

A driving control method, comprising: detecting, by a computer, a surrounding environment of a vehicle; controlling, by the computer, acceleration and deceleration of the vehicle according to a driving mode including a start standby mode in which the vehicle is started according to the surrounding environment when the vehicle is stopped and a stop maintenance mode in which a stopped state of the vehicle is maintained when the vehicle is stopped; and changing, by the computer, the driving mode from the start standby mode to the stop maintenance mode in a case where the driving mode is the start standby mode and a brake pedal operation is detected.
  11. 11 . A non-transitory computer-readable storage medium comprising a control program, wherein the control program, when executed by a computer, executes a driving control method, comprising: detecting, by the computer, a surrounding environment of a vehicle; controlling, by the computer, acceleration and deceleration of the vehicle according to a driving mode including a start standby mode in which the vehicle is started according to the surrounding environment when the vehicle is stopped and a stop maintenance mode in which a stopped state of the vehicle is maintained when the vehicle is stopped; and changing, by the computer, the driving mode from the start standby mode to the stop maintenance mode in a case where the driving mode is the start standby mode and a brake pedal operation is detected.

Description

TECHNICAL FIELD The present invention relates to a driving control device, a driving control method, and a non-transitory computer-readable storage medium. BACKGROUND ART In recent years, there have been increasing efforts to provide sustainable transport systems that take into consideration vulnerable transport participants. To achieve this, research and development of driving assistance technologies is conducted to further improve road safety and convenience. For example, WO2016/181725 and WO2018/159399 disclose a driving control device that enables autonomous driving.
