Pacific Automotive Network With the development of vehicle technology, self-driving vehicles have emerged. Self-driving vehicles are in an unmanned state. When the driving environment of the vehicle is relatively harsh, the driver of the manned vehicle can The operating status of the vehicle is controlled based on the observation of the surrounding environment of the vehicle to avoid dangers. However, driverless autonomous vehicles have poor automatic adjustment to deal with dangers.
Autonomous driving vehicles and their counterweight adjustment methods and processes Document serial number: 20878698 Release date: 2020-05-2616: 54 Navigation: X technology gt; latest patent gt; bicycle, non-motor vehicle device manufacturing technology Embodiments of the present invention relate to the field of vehicle technology, and in particular, to an autonomous vehicle and a counterweight adjustment method thereof.
Background technology: With the development of vehicle technology, self-driving vehicles have emerged. Self-driving vehicles are in an unmanned state. When the driving environment of the vehicle is relatively harsh, the driver of the manned vehicle can The operating status of the vehicle is controlled based on the observation of the surrounding environment of the vehicle to avoid dangers. However, driverless autonomous vehicles have poor automatic adjustment to deal with dangers.
Self-driving vehicles are prone to danger in windy weather. When strong winds blow from the front or rear of the vehicle, it will cause the self-driving vehicle to accelerate and decelerate. When strong winds blow from the side of the self-driving vehicle, , it will cause greater danger, ranging from causing the self-driving vehicle to sway left and right, causing the self-driving vehicle to easily rub against surrounding vehicles, to causing the self-driving vehicle to roll over, endangering the safety of the self-driving vehicle and surrounding vehicles.
Technical implementation elements: In view of this, the present invention provides an automatic driving vehicle and its counterweight adjustment method, which greatly reduces the left and right swing of the automatic driving vehicle caused by large lateral wind force and scratches with surrounding vehicles. , and even the probability of rollover, improving the lateral safety of autonomous vehicles in windy weather.
In the first aspect, embodiments of the present invention provide an autonomous vehicle, including a vehicle body, a counterweight adjustment component, a lateral counterweight component and at least one crosswind component provided on the vehicle body. Detection component; the crosswind detection component is used to detect the lateral wind force at the location of the autonomous vehicle; the counterweight adjustment component is communicatively connected with the crosswind detection component and is used to detect the crosswind according to the received crosswind. The detection results adjust the weight distribution of the lateral weight components on the autonomous vehicle.
Optionally, the crosswind detection component includes: a swing component, which is swung by the lateral wind at the location of the autonomous vehicle; and an angle detection component, which is used to detect the sway. The swing angle of the component is used to obtain the lateral wind force at the location of the autonomous vehicle.
Optionally, the crosswind detection component further includes: a rotating shaft, the axial direction of the rotating shaft is parallel to the traveling direction of the autonomous vehicle, and the crosswind swing component is capable of rotating around the The angle detecting component is arranged on one side of the sheet-like component of a rotating shaft that swings along the axial direction of the rotating shaft.
Optionally, the crosswind detection component further includes: a base, the base being used to fix the rotating shaft and the angle detection component.
Optionally, the self-driving vehicle further includes: a steering compensation component for obtaining the steering force of the self-driving vehicle; the counterweight adjustment component is communicatively connected with the steering compensation component, For adjusting the weight distribution of the lateral counterweight component on the autonomous vehicle according to the received crosswind detection result and the steering force of the autonomous vehicle.
