Abstract

The invention provides an automatic driving system which not only can realize the automatic driving of a single vehicle, but also can control the running of other vehicles. The automatic driving system comprises a main vehicle system arranged on a main vehicle, and a following vehicle system arranged on a following vehicle, wherein induction units, control units, execution units and information transmission units are arranged in both the main vehicle system and the following vehicle system, the induction unit comprises a vehicle speed sensor, a corner sensor and an external environment sensor, and the execution unit comprises an auxiliary steering mechanism, a throttle control device, a gear control device and an auxiliary brake body. The main vehicle control unit obtains the road information by the external environment sensor and realizes the automatic driving by controlling the execution unit, and the following vehicle utilizes the information of the main vehicle to control the running state thereof, so both of the main vehicle and the following vehicle do not need drivers. The automatic driving system is particularly suitable for the long-distance running of motorcades for combined self-driving tour and the like, relieves the fatigue strength of the driver of the following vehicle, and improves the safety and the comfort of running.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automatic driving system of an automobile. Background technique [0002] In order to adapt to the rapid development of the economy, the construction of expressways is getting faster and faster. The wide use of expressways has improved the convenience of life, but long-distance expressway driving will make drivers feel tired and boring, which will lead to fatigue driving. The number of security incidents is gradually increasing. Therefore, if the automatic driving of vehicles can be realized, especially if multiple vehicles in the group self-driving tour can realize automatic driving at the same time, the driving safety and driving comfort of the expressway will be significantly improved. [0003] Existing autopilot systems still require manual intervention, and can only be applied to a single vehicle. The actual effect is limited, especially for m...
