Embodiment 1

[0028] figure 1 The flow chart of a vehicle control method based on automatic driving provided by Embodiment 1 of the present invention is applicable to the situation where the automatic driving level falls back when the control is abnormal during the automatic driving process of the vehicle. The method of this embodiment can be based on automatic driving It can be implemented by a vehicle control device, which can be realized by hardware and / or software, and can generally be integrated into a vehicle navigation control device or a computer device. Such as figure 1 As shown, the method of this embodiment specifically includes:

[0029] S110 , when a control abnormality is identified according to the current vehicle state, a manual intervention prompt is performed.

[0030] Self-driving vehicles plan a space-feasible and time-controllable unmanned road network based on the current vehicle behavior (turning, climbing, meeting, accelerating or decelerating, etc.) and satisfying...

Embodiment 2

[0047] figure 2 A flow chart of a vehicle control method based on automatic driving provided by Embodiment 2 of the present invention is shown, and this embodiment further optimizes each optional implementation manner in the foregoing or following embodiments. Such as figure 2 As shown, the vehicle control method based on automatic driving specifically includes:

[0048] S210 , when a control abnormality is identified according to the current vehicle state, a manual intervention prompt is given.

[0049] S220. Determine that the vehicle is in an automatic driving degraded mode according to the driver's input behavior.

[0050] S230. In the automatic driving degraded mode, if the control abnormality exceeds the capability range of the operation design field, determine the untrusted control functions that have exceeded the capability range of the operation design field, and the trusted control functions that do not exceed the capability range of the operation design field. ...

Embodiment 3

[0063] image 3 A flow chart of a vehicle control method based on automatic driving provided by Embodiment 3 of the present invention is shown, and this embodiment further optimizes each optional implementation manner in the foregoing or following embodiments. Such as image 3 As shown, the vehicle control method based on automatic driving specifically includes:

[0064] S310. When a control abnormality is identified according to the current vehicle state, a manual intervention prompt is performed.

[0065] S320. If the control abnormality is that the automatic driving behavior does not match the scene, control the driving of the vehicle according to the manual control instruction input by the driver.

[0066] For example, the situation where the automatic driving behavior does not match the scene includes at least one of the following: a need to pull over or an emergency stop in a highway scene; a need to pull over or an emergency stop when vehicle communication is interrup...

Abstract

Embodiments of the invention disclose a vehicle control method and device based on automatic driving, equipment and a medium. The method includes the following steps: when control abnormality is recognized according to a current vehicle state, a manual intervention prompt is performed; it is determined that a vehicle performs an automatic driving degradation mode according to an input behavior ofa driver; and in the automatic driving degradation mode, according to the control abnormality, and combining a manual control instruction input by the driver and an automatic control instruction generated by an automatic driving system, driving of the vehicle is controlled. The technical scheme of the embodiments solves the problem that when a self-driving vehicle exits automatic driving, the vehicle directly stops running, the driver lacks of intermediate transition from completely not participating in vehicle control to safely controlling the vehicle, achieves that when a driving level of adriverless vehicle needs to be rolled back, if conditions are possible, rollback of moderate degradation is performed to reduce the burden of the driver, and is beneficial to maintain the safety effect.

Description

technical field [0001] Embodiments of the present invention relate to vehicle driving control technologies, and in particular to a vehicle control method, device, device and medium based on automatic driving. Background technique [0002] In recent years, autonomous driving technology has developed rapidly, and unmanned vehicles have entered people's lives one after another. [0003] In order to adapt to complex road traffic conditions, existing unmanned vehicles will also retain a manual driving mode, which allows the vehicle to switch between automatic driving and manual driving modes. Usually, when a vehicle breaks down, or a key component failure is detected, for example, in a dark environment at night, equipment failure, etc., it is possible to fall back to the level of automatic driving, return the driving right to the driver, and switch to manual driving mode . [0004] However, it is found during the research of the present invention that if the automatic driving m...
