Embodiment Construction

[0037]The present application discloses a speed control system and method for an automatic driving vehicle. The on-board electronic equipment on the self-driving vehicle can obtain the status data of the surrounding objects, judge whether the target object may constitute an obstacle to the self-driving vehicle during driving, and the type of obstruction that may constitute, and then treat the said object accordingly. The planned driving speed of the self-driving vehicle is adjusted so that it can avoid the obstacle or reduce the impact of the obstacle in the future driving process. The above system and method can also be applied to policy decisions of other autonomous driving devices. For example, the above-mentioned system and method can be used for the decision-making of driving strategies of aerial vehicles, surface ships, underwater ships and other equipment.

[0038] In the following detailed description, specific details of the invention are set forth by way of example ...

Abstract

The invention provides a speed control method and device for an automatic driving vehicle, a computer system and a readable storage medium. The method comprises the following steps: vehicle-mounted electronic equipment of the automatic driving vehicle can obtain the current state of the automatic driving vehicle at the current moment and space-time prediction data of a target object; for each target object, the vehicle-mounted electronic equipment can determine the conflict time and space between the vehicle-mounted electronic equipment and the automatic driving vehicle, and determine a planned driving track of the automatic driving vehicle according to the conflict time and space; and the vehicle-mounted electronic equipment further determines a target driving track from the planned driving tracks corresponding to the target objects, and sends a control instruction to the control equipment of the automatic driving vehicle according to the target driving track.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular, to a speed control system and method for an automatic driving vehicle. Background technique [0002] Self-driving cars are products of the new era and the development trend of future cars. Since autonomous vehicles determine their own driving strategies in real time during driving and participate in complex traffic environments that include many third-party vehicles (such as human-driven vehicles), the safety of their decision-making becomes the primary consideration. In addition, the speed and comfort of the self-driving vehicle traveling according to the driving strategy are also factors that need to be considered. Accurately predicting the dynamic changes of surrounding obstacles in complex traffic environments can help self-driving vehicles adjust their driving strategies in a timely manner. However, in different scenarios, the dynamic change trends of sur...
