Abstract

A car driver driving skill practice guiding an examination scoring device comprises a core plate and an interface baseplate connected with the core plate, wherein the core plate comprises a DSP digital processing unit, an embedded MCU micro-controller, a program storage, a data storage and interface connector plugins; the DSP digital processing unit and the embedded MCU micro-controller are taken as the center namely a hardware platform of the device; the DSP digital processing unit is responsible for processing digital audios and digital video so as to obtain state data required by movement locus of an examination vehicle and other information; the embedded MCU micro-controller provides an operation platform for an operating system; and in addition to the interface connector plugins, interfaces containing corresponding interface circuit devices are also arranged on the interface baseplate. A realization method for car driver driving skill practice guiding an examination scoring, by means of the device, can improve the reliability of measurement data of the actual position of the examination car. Therefore, the integration level of functions of the vehicle-mounted equipment is improved, and the purchase and the maintenance cost for the customer are lowered.

Description

technical field [0001] The invention relates to a driving skill test device for motor vehicle drivers, in particular to a driving skill practice guidance and test scoring device for car drivers and a method for realizing driving skill practice guidance and test scoring for car drivers. Background technique [0002] At present, the vehicle-mounted computer in the computer automatic assessment equipment for motor vehicle drivers' road driving skill test results is an X86 series hardware platform that can run MS Windows XP. Using this software and hardware platform, in fact, it only completes the following corresponding functions: [0003] 1. The GPS system is used to determine the driving trajectory, speed and direction of the test vehicle. [0004] 2. The speed and direction of the test vehicle are determined with the help of on-board sensors. [0005] 3. Through the on-board sensor to collect the switch status information of the test vehicle lights, etc., [0006] 4. C...
