Embodiment Construction

[0021] Embodiment of automatic driving control system for sanitation sweeper

[0022] This embodiment provides an automatic driving control system for a sanitation sweeper, which is used for automatic driving control of a sanitation sweeper, and there is no limitation on the applicable sanitation sweeper, which can be a sanitation sweeper with a traditional power source, such as a fuel car, It can also be a pure electric sanitation sweeper, and this embodiment uses a pure electric sanitation sweeper as an example for illustration.

[0023] The invention of the automatic driving control system of the sanitation sweeper lies in the two modules, namely the data acquisition module and the control module, wherein the data acquisition module is used to obtain relevant data information, and the control module is used to combine the internal The loaded control program realizes automatic driving control. Therefore, the inventive point of the present invention lies in the automatic dri...

Abstract

The invention relates to an automatic driving control method and system of a sanitation sweeper. In the automatic driving process, the position and actual speed of the sweeper, the state of an intersection signal light and the time for the signal light to keep the state are collected in real time, and the distance from the position of the sweeper and an intersection is obtained; when the signal light is green, the ratio of the distance to the remaining time of the green light is calculated, and if the ratio is larger than the actual speed of the sweeper, the sweeper is controlled to run at higher speed so that the sweeper can pass through the intersection before the green light is changed; when the signal light is red, the ratio of the distance to the remaining time of the red light is calculated, if the ratio is smaller than the actual speed of the sweeper, the sweeper is controlled to run at lower speed so that the sweeper can pass through the intersection after the red light turns into green. Therefore, the speed of the sweeper is correspondingly adjusted according to the state of the signal light and the state remaining time, it can be ensured that the sweeper can pass throughthe intersection before the green light is turned off or after the red light turns into green, people do not need to wait for the red light frequently, the sweeper is prevented from being started andstopped frequently, the energy consumption is reduced, and the sweeping efficiency is guaranteed.

Description

technical field [0001] The invention relates to an automatic driving control method and a control system of a sanitation sweeping vehicle, and belongs to the technical field of automatic driving of a sanitation sweeping vehicle. Background technique [0002] With the development of urbanization, the continuous improvement of market demand and the guidance of national policies, more and more new energy sanitation cleaning vehicles, that is, pure electric sanitation cleaning vehicles, are used in the market. Compared with traditional sanitation sweepers and manual sweepers, the environmental protection, cleaning efficiency and safety of new energy sanitation sweepers have been significantly improved. Moreover, with the development of cities and the continuous increase of labor costs, more and more attention has been paid to autonomous driving technology. At present, some companies in the world have begun to develop autonomous vehicles, and some autonomous vehicles have develop...
