Embodiment Construction

[0019] This patent applies ultrasonic detection technology, tactile sensing technology, elastic material technology and information processing technology to the safe driving of unmanned vehicles, realizing the safe driving and precise stop functions of unmanned vehicles, making unmanned vehicles When encountering an obstacle or a collision accident, it can brake or stop in time to realize safe driving. The following are introduced respectively:

[0020] Elastic guardrail is the core of the present invention, and it is the last hand brake of automobile safety, and will be loaded with ultrasonic emitter and tactile sensor again. PP materials are more and more widely used due to their low material cost. Talc powder and rubber are added to PP materials to improve material performance, and modifiers are added, such as zinc oxide, dilauryl thiodipropionate, nano Carbon black or titanium dioxide can improve its aging resistance to meet the long-term rigidity and crash resistance req...

Abstract

The invention relates to a driverless vehicle haptic-stopping method and device utilizing an ultrasonic guardrail. Tactile sensation is achieved by installing an annular guardrail on a vehicle head ofa driverless vehicle, and an ultrasonic wave transmitter is installed on the guardrail to achieve early warning detection before touch. The road condition can be sensed according to ultrasonic wave signals to judge obstacles, and the position of a road pile can also be sensed in advance during stop. When an emergency occurs, for example, inevitable collision, the guardrail plays a protective effect on pedestrians and a vehicle body.

Description

technical field [0001] The invention relates to a tactile parking method and device for an unmanned vehicle related to ultrasonic guardrail calibration. The invention can be used in the fields of obstacle identification, safety protection, pit stop and parking of unmanned vehicles. Background technique [0002] Unmanned vehicles use sensor technology, use information fusion to perceive the state of the vehicle itself and the surrounding environment, and control its own behavior by automatically operating the actuator. Unmanned vehicles with natural environment perception and intelligent behavior decision-making capabilities are intelligent systems integrating sensing technology, automatic control, artificial intelligence, visual computing, programming, integrated navigation, and information fusion. It can complete conventional vehicle functions including acceleration, deceleration, forward, backward, and steering, as well as autonomous behaviors such as positioning, path pla...
