Abstract

The invention provides an automatic following driving system. The driving system comprises a vehicle speed acquisition unit, an alarm unit and an alarm control unit, wherein the vehicle speed acquisition unit is used for acquiring the vehicle speed of a current vehicle, and the vehicle speed is acquired by reading CAN bus or LIN bus data; the alarm unit is used for giving an alarm; and the alarm control unit is used for controlling the alarm unit to give an alarm when the vehicle speed acquired by the vehicle speed acquisition unit meets a first preset alarm condition. According to the automatic following driving system, the driver can be reminded in time so that traffic safety accidents caused by the aspect of drivers in charge can be reduced.

Description

technical field [0001] The invention relates to the field of driving assistance systems, in particular to an automatic follow-up driving system. Background technique [0002] At present, when driving on the expressway, there is often a long time to follow the vehicle in front, and after a long period of driving, especially when there is a long period of driving before entering the high speed, the driver will not enter the high speed. When driving on the road, it is often easy to forget to keep the distance between vehicles, which may easily cause traffic safety accidents such as rear-end collisions. Contents of the invention [0003] The invention provides an automatic follow-up driving system, which can remind the driver of the vehicle in time, thereby reducing traffic safety accidents caused by the driver's supervisor. [0004] An automatic follow-up driving system provided by an embodiment of the present invention includes: [0005] The vehicle speed obtaining unit is...
