Problems solved by technology

[0004] Most of the traditional methods are to set the TTC (Time To Collision, collision time) to a fixed value or to set the reminder based on the safety distance between the vehicle and the vehicle in front. This method is inefficient and has the defect of not reminding the driver in time , there is a risk of collision

Embodiment 1

[0048] figure 1 It is a flowchart of a test method for a driver taking over a vehicle provided in this embodiment, and this embodiment is applicable to testing a driver taking over a vehicle. The method can be carried out by the driver taking over the test device of the vehicle, which device can consist of software and / or hardware and is generally integrated in the electronics.

[0049] Such as figure 1 As shown, the method provided in this embodiment includes the following steps:

[0050] S110. Determine the driver state according to the driver human factors data and the driver state model.

[0051] Among them, the above-mentioned "driver human factors data" refers to the collection of driver's physiological, psychological, cognition, behavior and other information, and can be used as a synchronous analysis of the driver's behavior performance, cognitive load, stress response, emotion, analysis, etc. The data foundation of heart and other states. Eye movement data, physio...

Embodiment 2

[0151] figure 2 It is a flow chart of another test method for a driver to take over a vehicle provided by this embodiment. This embodiment optimizes the step "in response to the completion of the takeover operation, determine the performance evaluation result of the human-machine takeover".

[0152] Such as figure 2 As shown, the method provided in this embodiment includes the following steps:

[0153] S110. Determine the driver state according to the driver human factors data and the driver state model.

[0154] S120. Responding to an emergency event, reminding the driver to take over the vehicle according to the driver's state and the takeover reminder mode associated with the driver's state.

[0155] S131. Determine the driver's takeover capability according to the human factor data of the driver before, when and after taking over the vehicle.

[0156] In this embodiment, the human factor data of the driver are collected before, during and after taking over the vehicle...

Embodiment 3

[0165] image 3 It is a schematic structural diagram of a test device for a driver taking over a vehicle provided by this embodiment, and this embodiment is suitable for testing a driver taking over a vehicle. The means may consist of software and / or hardware, and are generally integrated in electronic equipment. see image 3 , the device consists of:

[0166] The driver state determination module 301 is configured to determine the driver state according to the driver human factor data and the driver state model.

[0167] The driver taking over vehicle reminding module 302 is configured to remind the driver to take over the vehicle according to the driver's state and the takeover reminding mode associated with the driver's state in response to an emergency.

[0168] The man-machine takeover performance evaluation result determination module 303 is configured to determine the man-machine takeover performance evaluation result in response to the completion of the takeover ope...

Abstract

The invention relates to a test method and device for a driver to take over a vehicle, electronic equipment and a medium. The method comprises the following steps: determining a driver state according to driver human factor data and a driver state model; responding to the emergency event, and reminding a driver to take over the vehicle according to the driver state and a take-over reminding mode associated with the driver state; responding to the takeover completion operation, and determining a man-machine takeover performance evaluation result; and optimizing the driver state model and / or the reminding mode according to an evaluation result. According to the method, a driver state is determined based on driver human factor data, a driver is reminded to take over a vehicle in time after an emergency occurs, a man-machine take-over performance evaluation result is further determined after a take-over result is obtained, and a driver state model and / or a reminding mode are / is optimized according to the result. Therefore, the driver state judgment accuracy or the effectiveness of the reminding mode is improved, and the driver is ensured to take over the vehicle stably and effectively.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular, to a test method, device, electronic equipment and medium for a driver to take over a vehicle. Background technique [0002] For self-driving vehicles, when the automatic driving mode is turned on, the driving task can be handed over to the vehicle, and the driver can engage in things that have nothing to do with driving, thereby improving driving comfort. However, affected by various factors such as technology, standards, and laws, the future intelligent networked vehicles will go through a period of human-machine co-driving (including integrated functional automatic driving and automatic driving with driver participation in responses). When the automatic driving mode is turned on, when the vehicle system encounters an emergency that cannot be handled, the driver needs to intervene. [0003] Human-machine co-driving is an important stage in the development of autonomous d...
