Problems solved by technology

[0004] Due to limited driving skills, novice drivers are prone to stepping on the accelerator or brake pedal too heavily during the start and stop of the vehicle, resulting in rapid changes in vehicle speed in a short period of time. In addition, the steering wheel cannot be smoothly manipulated during the turning process of the vehicle, and repeated corrections are required In order to successfully complete the vehicle turning

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 1 As shown, the present invention divides the driver into two categories, one class is the driver who does not have driving experience and poor driving skills, i.e. the research object of the present invention: novice driver; another kind is the common driver.

[0044] A method for automatic identification and safety warning of a vehicle novice driver, comprising the following steps:

[0045] 1) Obtain massive data of novice drivers and ordinary drivers driving cars in the urban road environment, and construct the driving behavior of novice drivers according to the stability of novice drivers' own dri...

Abstract

The invention discloses an automatic identification and security early warning method for a vehicle novice driver. The method comprises the following steps: firstly, analyzing operating characteristics of the vehicle novice driver on a vehicle steering wheel, an accelerator pedal and a brake pedal on the basis of mass data regarding to the condition that the novice driver operates a car at the urban road environment, and building a novice driver driving behavior ethogram; and acquiring information of the vehicle steering wheel rotation angle, the accelerator pedal stroke and the brake pedal stroke by using a vehicle-mounted CAN bus, judging whether the current vehicle driver is a novice driver through analyzing the operating characteristics of the current vehicle driver on the steering wheel rotation and the accelerator / brake pedal on the basis of the comparison between the driving data of the vehicle driver and features of the novice driver driving behavior ethogram by adopting the dynamic time warping algorithm, and setting a more reasonable safe distance and early warning time on a vehicle safety assistant system for the novice driver.

Description

technical field [0001] The invention relates to the field of vehicle safety auxiliary driving, in particular to an automatic identification and safety warning method for a novice vehicle driver. Background technique [0002] According to statistics, in 2013, the number of deaths caused by traffic accidents caused by drivers with less than one year of driving experience in the country accounted for 15.4% of the total number of deaths caused by motor vehicle drivers, and among the accidents caused by speeding, drunk driving, etc. The driver accident rate is significantly higher. Novice drivers have a high accident rate due to poor driving skills, lack of driving experience, insufficient risk prediction ability, and prone to nervous and anxious driving emotions. At present, for the development of safety assisted driving equipment, no special safety warning measures have been set for the above-mentioned characteristics of novice drivers. Therefore, intelligently and accurately...
