Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] A flow chart of the first embodiment of a method for judging bad driving behavior of a vehicle turning right sharply according to the present invention, see figure 1 , the method includes:
[0024] 101: Obtain the angular velocity of the vehicle in the z-axis direction, where the z-axis direction is an upward direction perpendicular to the horizontal plane where the vehicle is located. The angular velocity of the vehicle in the z-axis direction is obtained through a six-axis sensor.
[0025] 102: Determine whether the z-axis angular velocity of the vehicle is less than the z-axis angular velocity threshold, and whether the z-axis angular velocity change value of the vehicle within the first preset time is less than the z-axis a...

Disclosed are a method and device for judging bad driving behaviour for a sharp right turn of a vehicle, which belong to the technical field of safe driving of vehicles. The method comprises: acquiring an angular velocity of a vehicle in the z-axis direction, the z-axis direction being a direction which is perpendicular to a horizontal plane, where the vehicle is located, and is upward; judging whether the angular velocity of the vehicle in the z-axis direction is less than an angular velocity threshold in the z-axis direction and whether a change value of the angular velocity of the vehicle in the z-axis direction within a first pre-set time is less than a change value threshold of the angular velocity in the z-axis direction; and if the angular velocity of the vehicle in the z-axis direction is less than the angular velocity threshold in the z-axis direction and the change value of the angular velocity of the vehicle in the z-axis direction within the first pre-set time is less than the change value threshold of the angular velocity in the z-axis direction, determining that the vehicle generates a sharp right turn. By means of the method and device for judging bad driving behaviour for a sharp right turn of a vehicle, the present invention realizes intelligently judging whether the driving behaviour of a driver is bad driving behaviour for a sharp right turn.
Description
technical field [0001] The invention relates to the technical field of safe driving of vehicles, in particular to a method and a device for judging bad driving behaviors of sudden right turns of vehicles. Background technique [0002] Vehicle posture monitoring is one of the important contents of active safety management of public transport vehicles. For public transport vehicles, especially buses and taxis, if the driver frequently performs dangerous driving behaviors such as rapid acceleration, rapid deceleration or sharp turns during driving, it will not only easily disturb the traffic order and cause traffic accidents, but also make passengers It feels so uncomfortable that it creates fear. Therefore, the use of advanced technology to realize the active monitoring of vehicle driving posture has important practical significance for regulating driving behavior, improving the quality of bus service, and reducing traffic accidents. [0003] At present, the research on vehi...
