Embodiment Construction

[0094] As described herein, an autonomous vehicle (referred to as a "vehicle" for simplicity) is capable of operating in automatic, semi-autonomous, or manual modes. In an automatic or semi-autonomous mode of operation, the vehicle's control system can operate the vehicle with no or limited human operator input. For example, the control system may apply the accelerator to accelerate the vehicle, may steer the vehicle, may apply the vehicle's brakes, and may operate auxiliary functions of the vehicle (eg, activate hazard warning lights). In these modes of operation, the control system receives sensor outputs from the sensor array to generate vehicle control signals to operate the vehicle. The sensor array may include light detection and ranging (Light Detection and Ranging (LIDAR)) sensors, one or more cameras, radar sensors, sonar sensors, and the like. The sensors in the sensor array enable the control system to detect obstacles, vehicles, pedestrians, cyclists, etc. on the ...

Abstract

A collision-avoidance system for use with an autonomous-capable vehicle can continuously receive image frames captured of the roadway to determine drivable space in a forward direction of the vehicle.The system can determine, for each image frame, whether individual regions of the image frame depict drivable space. The system can do so using machine-learned image recognition algorithms such as convolutional neural networks generated using extensive training data. Using such techniques, the system can label regions of the image frames as corresponding to drivable space or non-drivable space. By analyzing the labeled image frames, the system can determine whether the vehicle is likely to impact a region of non-drivable space. And, in response to such a determination, the system can generatecontrol signals that override other control systems or human operator input to control the brakes, the steering, or other sub-systems of the vehicle to avoid the collision.

Description

Background technique [0001] Autonomous vehicles / self-driving vehicles are vehicles that utilize intelligence, sensors and other autonomous technologies enabled by sensors and computers to replace human drivers. With existing technology, autonomous vehicles can easily handle traveling with other vehicles on roads such as highways. However, certain environmental and weather conditions may adversely affect the performance of certain sensors and automated driving systems and may pose challenges to autonomous vehicles. Contents of the invention [0002] According to one aspect of the present invention, a self-driving vehicle is provided, comprising: [0003] a plurality of sensors including cameras for capturing image frames in the direction of travel of the self-driving vehicle; [0004] a vehicle control system for controlling the self-driving vehicle, the vehicle control system configured to (i) receive sensor inputs from the plurality of sensors and (ii) generate vehicle co...
