Around-vehicle detection device for motor vehicle driver road driving skill examination system

Abstract

The invention relates to an around-vehicle detection device for a motor vehicle driver road driving skill examination system. The device comprises a vehicle-mounted signal comprehensive detection module installed on a motor vehicle, and an examination evaluation system connected with the vehicle-mounted signal comprehensive detection module; the device further comprises ultrasonic radar front probes and ultrasonic radar back probes which are arranged at the front vehicle body and rear vehicle body of the motor vehicle in a split manner; the ultrasonic radar front probes and the ultrasonic radar back probes are connected with an ultrasonic radar controller through electrical connection lines; and the ultrasonic radar controller is connected with the vehicle-mounted signal comprehensive detection model through an LIN bus. Novel ultrasonic detection is adopted, and therefore, the stability and applicability of the system can be improved.

Description

technical field [0001] The invention relates to a road driving skill test system for a motor vehicle driver in the intelligent transportation industry, in particular to a detection device for a motor vehicle driver's road driving skill test system that goes around a vehicle. Background technique [0002] In the traditional road driving skills test system for motor vehicle drivers, a switch is installed on the front and rear of the vehicle to detect the movement around the vehicle. The tail switch is not only cumbersome to operate, but often students do not know how to press the switch, resulting in failure of the exam, which often causes dissatisfaction and complaints from students. [0003] In view of the troublesome operation of the traditional switch button, and some students often forget to press it, which leads to disputes and complaints caused by the failure of the exam, etc., there is a non-contact detection around the car on the market, such as using an infrared sens...

Problems solved by technology

[0002] In the traditional road driving skills test system for motor vehicle drivers, a switch is installed on the front and rear of the vehicle to detect the movement around the vehicle. The tail switch is not only troublesome to operate, but often students do not know how to press the switch, resulting in failure of the exam, which often causes dissatisfaction and complaints from students

[0003] In view of the troublesome operation of the traditional switch button, and some students often forget to press it, which leads to disputes and complaints caused by the failure of the exam, etc., there is a non-contact detection around the car on the market, such as using an infrared sensor to detect whether there is a car around One-week action, but because infrared detection is easy to cause misjudgment in high temperature environment and when there are infrared objects around

[0004] To sum up, the existing switch button detection operation is cumbersome, and actual use often brings disputes

Non-contact infrared detection is prone to misjudgment and poor environmental adaptability
