Problems solved by technology

[0004] However, the existing HAD vehicles neither adjust nor plan the driving speed of the vehicle (e.g. slow down or speed up) until the state of the traffic light changes, which may lead to emergency braking or inefficient driving behavior
In addition, the sudden stop of the vehicle not only affects the driving comfort, but also may cause traffic accidents

Embodiment Construction

[0069] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0070] figure 1 A car 10 , a traffic light 20 , and a stop line 30 corresponding to the traffic light 20 and the car 10 are illustrated. An image recording device 11 such as a camera and a video camera is mounted on the car 10 and configured to sense and record image data of the environment of the car 10 .

[0071] The traffic light comprises a light part 21 which indicates different traffic states by showing instructions in different colors as well as arrow shapes. For example, a red ligh...

Abstract

A method for determining driving strategy of a vehicle comprises: obtaining (101) localization information of the vehicle; obtaining (102) a driving route of the vehicle; obtaining (103) a current driving velocity of the vehicle; detecting and interpreting (104) a current status of a traffic light; recognizing (105) a duration of the current status of the traffic light; detecting (106) a relevantstop line; obtaining (107) a distance between the stop line and the vehicle; and determining (108) whether to change the current driving velocity according to the current status of the traffic light,the duration of the current status of the traffic light, the distance between the traffic stop line and the vehicle, and the current driving velocity. A data processing device for determining drivingstrategy of a vehicle is also provided.

Description

technical field [0001] The present invention generally relates to the field of vehicles or robots, and more particularly to a method and device for determining a driving strategy of a vehicle. Background technique [0002] Autonomous driving technologies have been studied for many years, and many of the proposed benefits have been demonstrated in a wide variety of applications. Traffic lights control road use by displaying lights in standard colours. A green light means a pass time slot, while a red light indicates a block time slot for the corresponding road / intersection. Also, in many countries, such as China and Canada, traffic lights may have count information to tell how much time is left for the current light state. For example, a display placed next to a traffic light shows countdown information indicating how many seconds the current state of the traffic light remains. [0003] Traffic light detection is part of a driver assistance system (DAS), which is an applic...
