Abstract

The invention relates to an external intervention system of vehicle rollover and an intervention method. The system comprises a rollover detection subsystem, a working area monitoring subsystem, a rollover active intervention subsystem and a system controller, wherein the rollover detection subsystem comprises a tilt angle sensor, a lateral acceleration sensor and a rollover diagnostic device, theworking area monitoring subsystem comprises visual detectors arranged on the two sides of a vehicle, the rollover active intervention subsystem comprises a plurality of actuators installed on the twosides of the vehicle; the structures of the actuators are the same, and the actuators comprise connecting shells, separation guide shells, air bag set bases, air bag sets and cutting cables. According to the system, active intervention can be performed at the initial stage of rollover, so that the vehicle is stressed by the righting moment brought by the contact between the intervention air bagsand the ground, the vehicle can returned to a stable state from an instability state, and the vehicle is prevented from occurring complete rollover.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an external airbag type vehicle rollover intervention system and an intervention method. Background technique [0002] Traffic safety and traffic accidents have become a major social problem faced by the world today. For China, which is undergoing rapid development, the situation is even more severe. According to investigations, many traffic accidents that cause heavy personal and property losses are caused by vehicle rollovers, because vehicle rollovers always occur in a very short time, so that the driver has no time to feel the state of the car and take preventive measures. Relevant data show that if the on-board system and the driver can be effectively alerted 1 second before the potential traffic accident, 90% of the traffic accidents can be avoided, and if the driver can take corresponding measures 2 seconds before the traffic accident, almost All traffic acciden...
