Intelligent vehicle control system and method based on road surface tactile perception

Abstract

The invention provides an intelligent vehicle control system based on road surface tactile perception. The system comprises a strain sensor matrix, a tire, a high-speed slip ring, a data preprocessingunit, a wireless signal transmission unit, a tactile perception unit and a vehicle control unit, the strain sensor matrix is fixed on the inner wall of the tire, and the high-speed slip ring is fixedwith a rim; the strain sensor matrix is electrically connected with the data preprocessing unit, the signal input terminal of the high-speed slip ring is connected with the strain sensor matrix, andthe output terminal of the high-speed slip ring is connected with the data preprocessing unit; when the strain sensor matrix is strained to generate an electric signal, the electric signal is transmitted to the data preprocessing unit through the high-speed slip ring, the data preprocessing unit is connected with the wireless signal transmission unit and then transmits the signal to the tactile perception unit in a wireless mode, and the tactile perception unit is connected with the vehicle control unit. The invention further provides an intelligent vehicle control method, and driving safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of unmanned driving, and in particular relates to an intelligent vehicle control system and method based on road surface tactile perception. Background technique [0002] In recent years, unmanned driving technology has developed rapidly, and its main technical difficulties are concentrated in three aspects: perception, decision-making and control. [0003] Regarding the realization of the perception of unmanned vehicles, cameras and radars are generally used to perceive traffic conditions and surrounding buildings, that is, to obtain the surrounding environment information through visual perception, while the tactile perception of road surface information has yet to be studied. As the only part of the vehicle in contact with the ground, tires are also the medium through which the ground transmits driving force and braking force to the vehicle. The state of the tire can directly affect the driving stability ...
