Benefits of technology

The patent describes a vehicle control system that can maintain the vehicle in a stationary position, even after it is stopped. This is done by suppressing acceleration in response to deceleration requests, even when the vehicle is stopped. The system can easily stabilize the vehicle when it is stopped and can use various signals, such as a speed sensor or an electric parking brake, to further enhance brake hold control. Overall, this system allows for safe and stable vehicle control even when the vehicle is stopped.

Problems solved by technology

However, a technique allowing a vehicle platform to appropriately perform vehicle control in response to a command received from such an autonomous driving system has not yet been established, and there remains room for improvement.

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 ...
