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.

Example Embodiment

[0020] Example 1:
[0021] Such as figure 1 As shown, the automatic driving system of this embodiment includes a master car system installed on the master car and a slave car system installed on the slave car. Both the master car system and the slave car system include a sensing unit, a control unit, and an execution unit. Unit and information transmission unit, the sensing unit includes a vehicle speed sensor, a rotation angle sensor and an external environment sensor, the external environment sensor includes an image sensing system and a ranging radar, and the execution unit includes an auxiliary steering mechanism, a throttle control device, A gear control device and an auxiliary brake mechanism, the information transmission unit includes an information receiving module, an information conversion module and an information transmission module, and transmits information through one or more of Wi-Fi, WiMax or Zigbee;
[0022] In the main vehicle system: the control unit receives the road surface information collected by the external environment sensor and the driving state information collected by the vehicle speed sensor and the turning angle sensor, and generates a control signal based on the above information and transmits it to the auxiliary steering mechanism, throttle control device, At least one of the gear control device and the auxiliary braking mechanism to control the acceleration, acceleration, steering, braking and other driving conditions of the main vehicle;
[0023] The control unit of the master vehicle system transmits the driving status information of the master vehicle, road surface information, and control signals generated according to the road surface information and driving status information to the slave vehicle system through the information transmission unit in real time;
[0024] In the slave car system: the control unit learns the distance from the master car through external environment sensors, and combines the received driving state information of the master car system, road information and the master car's control signal to generate and transmit the control signal of the slave car To at least one of the auxiliary steering mechanism, the throttle control device, the gear position control device, and the auxiliary braking mechanism to control the traveling state of the slave vehicle.
[0025] The control units of the master vehicle system and the slave vehicle system are also connected to an on-board multimedia system, so that multimedia data such as video, pictures, and audio can be shared between the master vehicle and the slave vehicle.
[0026] The master vehicle control unit in the above-mentioned automatic driving system uses external environment sensors to obtain road surface information, and realizes automatic driving through the control execution unit, while the slave vehicle uses the master vehicle's information to control its driving state, so both the master vehicle and the slave vehicle There is no need for the driver to intervene; when the road conditions are more complicated, the master car can be controlled by the driver, and the slave car does not require the driver to intervene. The automatic driving system is particularly suitable for long-distance driving in a combined self-driving tour and other fleets, reducing the fatigue of the driver, and improving driving safety and comfort.
