Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that the existing driving mode switching scheme cannot guarantee that the unmanned vehicle can quickly and effectively switch to the automatic driving mode, especially when the automatic driving mode is abnormal. Remote takeover mode, and for the problem that the remote control signal may be unstable due to network abnormalities, there is no effective countermeasure, which reduces the safety of driverless cars

Abstract

The embodiment of the invention discloses a remote takeover method, device and equipment of driverless car, and a storage medium. The method comprises the following steps: acquiring driving state reference information according to the currently located automatic driving mode of the driverless car; if determining that the driverless car is in an abnormal driving state, generating alarm informationand sending to a remote control side; exiting the automatic driving mode according to a returned remote control request and entering a remote takeover mode; sending the remote control reference information to the remote control side; receiving and judging whether the external control instruction satisfies an instruction stabilization condition; if the external control instruction dissatisfies theinstruction stabilization condition, controlling the driverless car to decelerate to stop. Through the remote takeover method disclosed by the embodiment of the invention, the driverless car can be quickly and effectively switched to the remote takeover mode when the automatic driving mode is in abnormity; the driverless car can be controlled when the problem that the external control instructionis lost, wrong to continue or large in delay occurs, and the security of the driverless car is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of unmanned driving technology, and in particular to a remote takeover method, device, device and storage medium for unmanned vehicles. Background technique [0002] With the development of science and technology, unmanned driving technology is in a critical period of vigorous development. During the landing process of unmanned driving, how to help the unmanned vehicle solve the extreme and special road conditions that it cannot handle without a safety officer in the driving position is an important technical problem that needs to be solved urgently. Remote takeover is such an unmanned driving assistance technology that allows security personnel to operate the vehicle without being in the vehicle. It is a crucial link in the landing and operation of unmanned driving. [0003] In the process of realizing the present invention, the inventor found that the existing driving mode switching scheme can...
