Embodiment 1

[0019] figure 1 It is a flow chart of the energy-saving control method for the unmanned vehicle system provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the unmanned vehicle is driving on the road, and the method can be executed by the control terminal integrated on the unmanned vehicle , including the following steps:

[0020] Step 101, determine whether the unmanned vehicle is in the parking waiting state through the sensing device and the high-precision map.

[0021] During the driving process, the unmanned vehicle can sense the road conditions and the driving conditions of other surrounding vehicles through the on-board sensing equipment. Exemplarily, the sensing device includes radar, sonar, high-definition camera, laser and so on. Among them, in addition to the precise positioning of the unmanned vehicle, the radar can also measure the driving speed of the vehicles in front and behind the unmanned vehicle. Preferabl...

Embodiment 2

[0029] figure 2 It is a flow chart of the energy-saving control method of the unmanned vehicle system provided by the second embodiment of the present invention. On the basis of the first embodiment, this embodiment provides a specific unmanned vehicle system when the unmanned vehicle is in the parking state. Energy-saving control methods, including:

[0030] Step 201, determine whether the unmanned vehicle is in a traffic jam waiting state through the radar module and the high-precision map in the unmanned vehicle.

[0031] During the actual driving process, unmanned vehicles often encounter traffic jams due to the complexity of road conditions. This situation may be caused by unexpected situations such as road construction or traffic accidents. When unmanned vehicles are in traffic jams, they will be parked for a long time If the unmanned vehicle system is still in full operation, it will obviously cause a lot of unnecessary losses. In this step, use the radar module and ...

Embodiment 3

[0037] image 3 The flow chart of the energy-saving control method for the unmanned vehicle system provided by Embodiment 3 of the present invention. This implementation is based on the above-mentioned embodiments, and a specific unmanned vehicle system is given when the unmanned vehicle is in a parking state. Energy-saving control methods, including:

[0038] Step 301, determine whether the unmanned vehicle is in the traffic light waiting state through the video module and high-precision map in the unmanned vehicle.

[0039] During the actual driving process, when the unmanned vehicle travels to a road intersection or a crosswalk, it will recognize the traffic lights on the road to determine whether it can pass through normally. For example, when the recognized traffic lights are red lights, no People and vehicles need to brake and wait; when the recognized traffic light is green, they can pass normally; if the recognized traffic light is yellow and continues to flash, they ...

Abstract

The invention discloses an energy-saving control method and device for an unmanned vehicle system. The method includes: determining whether the unmanned vehicle is in a parking waiting state through a sensing device and a high-precision map; if the unmanned vehicle is in a parking waiting state, control The unmanned vehicle system is on standby. This solution reduces the loss of the unmanned vehicle system, improves the battery life of the unmanned vehicle, and makes the design of the unmanned vehicle more environmentally friendly.

Description

technical field [0001] Embodiments of the present invention relate to intelligent control technology, and in particular to an energy-saving control method and device for an unmanned vehicle system. Background technique [0002] With the development of science and technology, there are more and more technical researches on unmanned vehicles, also known as unmanned vehicles, and they are becoming more and more mature. Since the 1970s, developed countries such as the United States, the United Kingdom, and Germany have begun research on unmanned vehicles, and have made breakthroughs in feasibility and practical application. China began research on unmanned vehicles in the 1980s, and the National University of Defense Technology successfully developed China's first truly unmanned vehicle in 1992. [0003] The driverless car controls the steering and speed of the vehicle based on the information obtained from the perception of the road, vehicle position and obstacles, so that the...
