Device and system for acquiring parking lot parameters

Abstract

The invention discloses a device and a system for acquiring parking lot parameters, which aim to solve the problem of larger errors of the lengths of parking lots acquired by intelligent parking auxiliary systems under the condition that running tracks formed when vehicles are close to the parking lots are not parallel to boundaries of the parking lots in the prior art. The device comprises a first computing module, a second computing module and a third computing module, wherein the first computing module is used for acquiring the running tracks of the vehicles according to vehicular speeds and turn angles of steering wheels; the second computing module is used for acquiring positions of a series of points on boundaries of obstacles according to the running tracks of the vehicles and a series of distances detected from fixed points on the vehicles in the running process of the vehicles to the obstacles nearby the parking lots; and the third computing module is used for acquiring the lengths of the parting lots according to the positions of a series of points on the boundaries of the obstacles. By using the device and the system, more accurate parking of drivers is facilitated.

Description

technical field [0001] The invention relates to the technical field of driver assistance systems, in particular to a device and system for acquiring parking space parameters. Background technique [0002] As the intelligent equipment of modern automobiles, the driver assistance system has been paid more and more attention to and used by the majority of people. Among them, the reversing radar in the parking process is widely installed and used as a parking aid. However, the ability to recognize obstacles alone cannot help the driver easily park the vehicle into the parking space, especially in a small parking space, so an intelligent parking assistance system has emerged as the times require, and is becoming more and more popular. The more people get noticed. [0003] Known intelligent parking steering systems use ultrasonic sensors to detect parking spaces. The calculation method for parking space detection is mainly to use ultrasonic sensors to detect the gap between vehic...
