Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] A driver-interactive rollover warning system for commercial vehicles, such as figure 1 As shown, it includes three parts: information collection system 1, rollover warning control unit 2, and rollover warning display unit 3.

[0039]The information collection system 1 is used to collect the CAN signals of various sensors and the whole vehicle, so as to provide the required vehicle status information and road information for the rollover warning control unit 2 (single chip microcomputer). The required sensor signals come from the lateral acceleration sensor 12 installed at the center of mass of the vehicle, the longitudinal acceleration sensor 13 , the yaw rate sensor 14 and the suspension displacement sensor 15 located at the suspension. Vehicle status information can be obtained from the vehicle CAN bus system 11: vehicle speed, steering whee...

Abstract

The invention relates to a driver-interactive type commercial vehicle rollover warning method and system. The driver-interactive type commercial vehicle rollover warning method includes curved-road rollover risk warning and lateral position risk warning; the curved-road rollover risk warning is characterized by judging rollover tendency of a vehicle to run in a curved road by inquiring a MAP table to acquire the critical speed when learning that a road ahead is to enter the curved road from the straight road; the lateral position risk warning is characterized by utilizing critical lateral acceleration acquired by a driver inputting the critical lateral acceleration MAP table into a steering wheel to judge the rollover tendency of the current vehicle. The driver-interactive type commercial vehicle rollover warning system comprises an information acquisition system, a rollover warning control unit and a rollover warning display unit. Rollover risk degree of the vehicle under the future road conditions can be judged through comprehensive consideration of vehicle state information and road information, and the driver can be prompted in advance in a proper and easily understandable mode, so that the driver can take timely measures, safe driving habits of the driver can be cultivated, and driving safety of the vehicle can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety control, and mainly relates to the acquisition and early warning of safety information, in particular to a driver-interactive commercial vehicle rollover early warning method and system. Background technique [0002] The popularity of automobiles has brought great convenience to people and society, but the frequent occurrence of various traffic accidents every year has also caused huge losses. Among them, the number of traffic accidents caused by vehicle rollover is second only to collision accidents, and commercial vehicles due to their own structural characteristics (such as high center of gravity, large height-to-width ratio, large turning radius, etc.), compared with other types of vehicles, Rollover accidents are more likely to occur. At the same time, due to the passenger or freight function of commercial vehicles, once a rollover accident occurs, serious casualties and pro...
