Passenger vehicle, and system and method for anti-rollover control for passenger vehicle

Abstract

The invention discloses a system and a method for anti-rollover control for a passenger vehicle. The system comprises two distance measuring sensors which are mounted on two sides of the bottom of the passenger vehicle body symmetrically and are used for measuring the distances H1 and H2 between of either of the two sides of the passenger vehicle body and the road during steering process, an anti-rollover controller which is connected with the two distance measuring sensors and a brake device of the passenger vehicle and is used for calculating the rollover angle m of the passenger vehicle through calculating the ratio of the absolute value of the difference between H1 and H2 and the distance L between the two distance measuring sensors, and is used for sending rollover control signal to the brake device of the passenger vehicle when the rollover angle m is compared with the preset rollover value M and m is higher than M, and the brake device of the passenger vehicle, which is used for performing brake according to the anti-rollover control signal and reducing the steering speed of the passenger vehicle. According to the invention, the anti-rollover control of the passenger vehicle is performed according to the rollover angle of the passenger vehicle; active brake is performed for the passenger vehicle under condition that the passenger vehicle may roll over, so that the probability of rollover of the passenger vehicle is reduced, and the steering safety of the passenger vehicle is increased.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a passenger car anti-rollover control system and method, and a passenger car using the passenger car anti-rollover control system. Background technique [0002] The rapid development of the contemporary economy has led to the rapid development of the transportation industry, making the relationship between people increasingly close, in which passenger cars have played an inestimable role; the widespread use of passenger cars has made the relationship between people The communication is more frequent and the distance is constantly shortened, which not only improves the quality of life, but also speeds up the pace of life. At present, passenger cars have become an indispensable means of transportation for people to travel. [0003] In recent years, with the continuous innovation of passenger car technology and the rapid development of expressways, the driving speed of passe...
