Benefits of technology

[0009]The first command may continue to request a constant deceleration value during a period from when the second command requests to maintain stationary until the second signal indicates standstill. Further, the constant deceleration value may be −0.4 m/s2. According to the above configuration, a state of the vehicle when the vehicle is stopped is easily stabilized by simple control.
[0010]In the above vehicle, the autonomous driving system may further obtain a third signal indicating a moving direc

Abstract

A vehicle comprises an autonomous driving system and a vehicle platform that controls the vehicle in response to a command received from the autonomous driving system. In the present vehicle, when the autonomous driving system issues a first command to request the vehicle platform to provide deceleration to stop the vehicle and a first signal indicates 0 km/h or a prescribed velocity or less, the autonomous driving system issues a second command to request the vehicle platform to maintain stationary. And after brake hold control is finished, a second signal indicates standstill. Until the second signal indicates standstill, the first command continues to request the vehicle platform to provide deceleration.

Description

[0001]This nonprovisional application is based on Japanese Patent Application No. 2020-015719 filed with the Japan Patent Office on Jan. 31, 2020, the entire contents of which are hereby incorporated by reference.BACKGROUNDField[0002]The present disclosure relates to a vehicle and an autonomous driving system, and more specifically to a technology used to autonomously drive a vehicle.Description of the Background Art[0003]Japanese Patent Laid-Open No. 2018-132015 discloses a technology used to autonomously drive a vehicle. In the technology described in Japanese Patent Laid-Open No. 2018-132015, an autonomous driving ECU having a function to sense a vicinity of a vehicle is provided to the vehicle separately from an engine ECU, and the autonomous driving ECU issues an instruction to the engine ECU via an in-vehicle network. The ECU for managing the power of the vehicle and the ECU for autonomous driving that are independent from each other allow an autonomous driving function to be ...
