Definitions
- the present invention pertains to technology enabling the detection of obstacles in front of an autonomous vehicle, and the control of the vehicle in order to avoid such an obstacle.
- UGV unmanned ground vehicle
- a remote-operated UGV is a vehicle that is controlled by a human operator via a communications link. All measures are decided by the operator based on either direct visual observation or with the use of sensors, such as digital video cameras.
- a remote-operated UGV is a remote-operated toy car.
- An autonomous vehicle herein means a vehicle which is capable of navigating and manoeuvring without human control.
- the vehicle uses sensors to obtain an understanding of the surrounding environment. Sensor data are then used by control algorithms to determine the vehicle's next step with respect to a superior goal for the vehicle, such as to collect and deliver goods at different positions.
- an autonomous vehicle must be able to scan the surrounding environment sufficiently well to be able to carry out the task which it has been allocated, e.g. "move the boulders from place A to place B via the mine gallery C".
- the autonomous vehicle needs to plan and follow a route to the chosen destination while detecting and avoiding obstacles on the way. In addition, the autonomous vehicle must complete its task as quickly as possible without making any mistakes.
- Autonomous vehicles were developed, among other things, for use in hazardous environments, such as the defence and war industry and the mining industry, both above ground and underground. If people or ordinary, manually-controlled vehicles approximate the operating area of the autonomous vehicles, for safety reasons they normally trigger an interruption in the operation. Once the operating area is clear, the autonomous vehicles may be ordered to resume operation.
- the autonomous vehicle uses information relating to the road, the surrounding environment and other aspects that impact the progress in order to automatically regulate throttle, braking and steering.
- a careful assessment and identification of the planned progress is necessary in order to assess whether a road is navigable and is also necessary in order to successfully replace a person's assessment when driving the vehicle.
- Road conditions may be complex, and when driving an ordinary manned vehicle the driver makes hundreds of observations per minute and adjusts the operation of the vehicle based on the perceived road conditions in order to find e.g. a navigable path around an object which may be on the road.
- To replace the human perception ability with an autonomous system entails, among other things, that the ability to perceive objects in an exact manner is required, in order to be able to control the vehicle effectively when steering past these objects.
- the technological methods used to identify an object in connection with the vehicle comprise, among other things, the use of one or several cameras and radar to create pictures of the surrounding environment.
- Laser technology is also used, both scanning lasers and fixed lasers, in order to detect objects and to measure distances. These are often called LIDAR (Light Detection and Ranging) or LADAR (Laser Detection and Ranging).
- LIDAR Light Detection and Ranging
- LADAR Laser Detection and Ranging
- the vehicle is equipped with different sensors, among other things, to detect speed and accelerations in different directions. Positioning systems and other wireless technology may also be used to determine whether the vehicle is e.g. getting close to a junction, a narrowing of the road, and/or other vehicles.
- US-2008189036-A1 describes a system for autonomous vehicles which detects obstacles with a camera.
- the system uses a camera to produce a 3D map of obstades in the area. This map is then sent to a module which uses the map in an algorithm to avoid the detected obstades.
- US-20090088916-A1 describes a system for autonomous vehicles which is able to plan its path automatically, and simultaneously avoiding collision with different types of obstacles.
- the system uses mathematical algorithms to calculate the correct path and how the vehicle should avoid obstades.
- the system uses different types of sensors, among others lasers, in order to gather necessary information and data.
- One objective of the invention is thus to provide a system to defect obstacles in the vehicle's path, and to control the vehicle so that the vehicle avoids driving into the obstacle, at the lowest cost possible, and in particular a system that controls the vehicle, so that the vehicle diverges from a planned trajectory as little as possible, Summary of the invention
- the objective of the invention is achieved through a system for controlling an autonomous vehicle with at least one first pair of wheels, in connection with obstacles according to the first independent claim.
- the system comprises a processor device which is adapted to receive an obstacle signal ⁇ 1 with information about an obstacle in the vehicle's path, the information comprising at least one characteristic of the obstacle and the position of the obstacle.
- an obstacle signal ⁇ 1 with information about an obstacle in the vehicle's path, the information comprising at least one characteristic of the obstacle and the position of the obstacle.
- Straddling means intentionally driving over an obstacle without any of the vehicle's wheels or the underside of the vehicle hitting the obstacle.
- the vehicle does not need to drive around the obstacle, but may instead make a smaller diversion from a current trajectory which the vehicle is following.
- the vehicle's ground clearance means the shortest distance between the ground level and the lowest fixed point of the vehicle. This distance may vary between the wheels, and other items below the vehicle.
- the objective of the invention is achieved with a method to control an autonomous vehicle with at least one pair of wheels in connection with obstacles.
