Abstract

The invention provides an automatic parking device of a large vehicle based on a magnetic nail; and the device comprises a vehicle-mounted sensor, an actuator, a controller and a magnetic nail lane, wherein the vehicle-mounted sensor comprises a magnetic ruler, an inertial navigation module and a speedometer. When the vehicle enters a station, the vehicle is driven on the magnetic nail lane; the controller measures the position of the magnetic nail on the magnetic nail lane corresponding to a vehicle body through the magnetic ruler to judge a transverse vehicle error, and detects the magnetic pole change of the magnetic nail to judge the parking position; the inertia navigation module and the speedometer are used for combining the information of the magnetic nail to fuse data; the controller calculates the longitudinal driving distance and the transverse error of the vehicle; and the vehicle navigation control is realized through controlling the steering system and a braking system to achieve the purpose of high-precision station parking. The device is suitable for such various places needing high-precision parking of large vehicles as BRT bus rapid transits, industrial factory buildings and wharfs, can effectively reduce manmade wrong operations, improves the success rate and the efficiency, and has such advantages as low cost and high reliability.

Description

technical field [0001] The invention relates to the technical field of unmanned public transportation, in particular to a large-scale vehicle automatic parking device based on magnetic nails. Background technique [0002] In recent years, unmanned driving technology has developed rapidly. The development of various sensor technologies such as GPS, radar, lidar, and camera provides many ways for unmanned vehicles to perceive the environment. Various electronically controlled actuators (such as power steering systems, EPS systems, etc.) have already been widely used in automobiles. These electronically controlled actuators provide strong support for future unmanned vehicles to replace human driving. Due to the complexity of the actual driving environment and the perfection of traffic regulations, unmanned vehicles in the true sense cannot be applied and popularized in the short term. However, unmanned vehicle technology can first be applied to local traffic scenarios with si...
