Embodiment Construction

[0015] figure 1 It is a block diagram of a vehicle auxiliary driving system according to an embodiment of the present invention, and the vehicle auxiliary system includes a monitoring platform 110 and a vehicle terminal 120 .

[0016] The vehicle-mounted terminal 120 is a GPS vehicle-mounted terminal, which includes a vehicle information acquisition module 121 , an alarm module 122 and a prompt rest module 123 .

[0017] The vehicle information acquiring module 121 is used to periodically acquire the latitude and longitude information of the vehicle to which the vehicle-mounted terminal 120 belongs from the GPS positioning satellite, and send the latitude and longitude information to the monitoring platform 110 in a wireless manner.

[0018] The alarm module 122 sends out an alarm sound when the monitoring platform 110 issues an early warning command to remind the driver that the driver is fatigued.

[0019] The prompt rest module 123 prompts the driver the address of the nea...

Abstract

The invention relates to vehicle DAS (Driver Assistant System) and method. The system comprises a vehicle-borne terminal and a monitoring platform. The method comprises the following steps of: firstly, periodically acquiring the latitude and longitude information of a vehicle with the vehicle-borne terminal according to the configuration of the monitoring platform and sending the latitude and longitude information of the vehicle to the monitoring platform by the vehicle terminal; then, calculating to acquire the continuous driving time of the vehicle and / or the offset distance of an offset preset line of the vehicle according to the latitude and longitude information of the vehicle by the monitoring platform and / or searching to acquire a parking lot spot for a driver to rest and sending an early warning command to the vehicle-borne terminal when early warning conditions are triggered by the vehicle; and finally, reminding the driver of fatigue driving in a voice or word mode and / or informing the driver of the parking lot address by the vehicle-borne terminal after receiving the early warning command of the monitoring platform. The invention not only can remind the driver of fatigue driving, but also can actively search a parking lot for the driver to rest, therefore the invention can be applied to the field of traffic systems.

Description

technical field [0001] The invention relates to an intelligent traffic system, in particular to a vehicle driving assistance method. Background technique [0002] Along with improving day by day of economic level, the use of automobile is more and more extensive, yet while making things convenient for people to travel, the traffic accident that produces is also more and more, wherein a large part is caused by fatigue driving. [0003] Fatigue driving has always been the killer of human roads. When the driver is tired, he will have blurred vision, dull movements, swollen hands and feet, lack of concentration, and slow response. If he still drives reluctantly at this time, it is likely to lead to traffic accidents. [0004] According to the survey, the current traffic accidents due to fatigue driving account for about 20% of the total traffic accidents, and account for 40% of the serious traffic accidents. Traffic accidents will not only cause a lot of property damage, but als...
