Embodiment Construction

[0045] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0046] The invention uses the driving simulator to collect the vehicle motion state under the operation of the driver to establish a driving behavior habit model, which is used to identify and analyze the driver’s behavior habit, virtual road line according to the recognized driving behavior habit, and establish an adaptive lane departure alarm Algorithms and devices.

[0047] Such as figure 1 As shown, the driving behaviors related to lane departure warning are usually classified as: driving on the common horizontal straight roads and roads with small curvatures on highways are divided into driving on the left, driving in the center, and driving on the right; large curvatures such as highway entrances and exits When driving on a curve, it is divided into parallel turning and cutting.

[0048] The driving simulator can be used to simulate the driver's manipulatio...

Abstract

The invention provides a vehicle yaw detection device comprising an environment sensing module, a road virtual device, and TLC (Thin Layer Chromatography) calculation device. The environment sensing module comprises a vehicle condition sensing device for obtaining vehicle condition information and a road condition sensing device for obtaining road condition information; the road virtual device is used for calculating a road virtual amount by a travelling type of the current vehicle according to the data obtained by the vehicle condition sensing device and the road condition sensing device; and the TLC calculation device is used for calculating the TLC according to the calculated road virtual amount and the data obtained by the vehicle condition sensing device and the road condition sensing device. With the adoption of the vehicle yaw detection device provided by the invention, a driver has enough time to adopt remedial measures in a corresponding time threshold value when the vehicle is about to yaw, and frequent alarms are not caused to disturb the driver.

Description

Technical field [0001] The present invention relates to a vehicle auxiliary driving device, in particular to a vehicle yaw detection device. Background technique [0002] For a car driving on a highway, the driver is tired of driving for a long time, or is bored with a long straight road, or is inattention caused by illness, calling, or taking care of minors around, causing the car to deviate from the current situation. Driving in the lane, driving into an adjacent lane or rushing out of the road, causing a traffic accident. [0003] When the car is about to deviate from the lane, the sound, light and vibration are used to remind the driver to take correct operation measures, which can effectively reduce and avoid traffic accidents. The lane departure warning system is a safety system based on basic traffic rules. Its main function is to assist drivers who are overly tired or drive monotonously for a long time to keep the vehicle in the lane in high-speed or similar highway enviro...
