Embodiment 1

[0042] This embodiment provides an integrated cruise system exit reminder method, which can be applied to the advanced driving assistance system of the vehicle, such as figure 1 As shown, it includes the following steps:

[0043] S101: When the integrated cruise system is turned on, obtain the driver's status data; the driver's status data can be the driver's heartbeat, pulse, facial expression, binocular coordinates, etc., select the corresponding sensor or detector in the prior art accomplish.

[0044] S102: If the driver state data indicates that the driver cannot perform a safe driving operation, send out a warning signal for a preset time to remind the driver to drive safely. The preset time can be set to be more than 5 seconds, and the warning signal can be a sound, an image, or a combination of sound and image.

[0045] In the above scheme of this embodiment, when the integrated cruise system is on, the driver status data can be obtained in real time, and it can be ju...

Embodiment 2

[0047] In the integrated cruise system exit reminder method in this embodiment, the driver state data includes a fatigue driving judgment result for determining whether the driver is fatigued driving and / or an emotion judgment result for determining whether the driver has a bad mood, The fatigue driving determination result and / or emotion determination result are obtained according to the driver's facial recognition result, and the facial recognition result can be realized by components such as an infrared camera. The existing infrared camera is equipped with a processing chip inside. When the driver's facial image is detected, it can directly conduct intelligent analysis based on the detection result to obtain whether the driver is tired or in bad mood. The output terminal can directly output the detection result. corresponding signal. According to the driver's facial recognition results, it can be accurately determined whether the driver is driving in fatigue or in bad mood....

Embodiment 3

[0054] In the integrated cruise system exit reminder method in this embodiment, the driver state data includes an attention determination result for determining whether the driver is paying attention, and the attention determination result is obtained according to the driver's binocular coordinate tracking result . According to the tracking result of the driver's binocular coordinates, it can be accurately determined whether the driver's attention is concentrated, and according to this determination result, it can be accurately determined whether the driver can take over the vehicle at any time.

[0055] On the basis of the above scheme, if image 3 As shown, the integrated cruise system exit reminder method may specifically include the following steps:

[0056] S301: Acquiring an attention determination result for determining whether the driver is paying attention when the integrated cruise system is in an on state.

[0057] S302: If the driver state data continues to indic...

Abstract

The invention provides an integrated cruise system exit method and device. The integrated cruise system exit method comprises the following steps: when the integrated cruise system is in an on state,obtaining driver state data; and if the driver state data indicates that the driver is unable to perform a safe driving operation, sending a warning signal for a preset time to remind the driver to drive safely. The above scheme provided by the integrated cruise system exit method can find the dangerous driving behavior of the driver when using the integrated cruise system in time by acquiring thedriver's state data to judge the driver's driving state, such as inattention, emotion and fatigue, thus being able to timely and effectively warn and ensure that the integrated cruise system is usedunder the premise of effective monitoring of the driver.

Description

technical field [0001] The invention relates to the technical field of driving assistance for automobiles, in particular to a method and device for exiting an integrated cruise system. Background technique [0002] As a main part of Advanced Driver Assistance Systems (ADAS: Advanced Driver Assistance Systems), integrated cruise control has been used in more and more vehicle configurations. It is mainly realized by the forward-facing millimeter-wave radar and the megapixel infrared camera as sensors, which can be turned on when the lane lines are clear or there are road conditions guided by the vehicle in front. After the system is turned on, the vehicle will keep in the middle of the lane line and drive according to the preset driving condition parameters. At this time, the system will automatically take over the driving controls such as braking, longitudinal acceleration, lateral steering, and gear shifting. The driver only needs to Put your hands on the steering wheel wit...
