Problems solved by technology

However, this method of installing gyro sensors is relatively expensive, and at the same time, it cannot obtain information on whether the wheels are off the ground in time, which is not very accurate and has poor universality.
At the same time, someone proposed a method to calcul

Abstract

The invention provides a vehicular anti-rollover dynamic monitoring, early warning and active intervention control method and a control system. The control system comprises a capacitive sensor, an anti-rollover early warning controller ECU (electronic control unit), an alarming device, a fault detection device and a CAN (controller area network) bus. The capacitive sensor is mounted at the center of a plate spring of an axle and used for dynamically measuring load capacity of each wheel in real time; the controller ECU acquires values from the sensor and is used for monitoring the load capacity of each tire. Whether a vehicle has risks of unbalance loading and rollover or not in a running process is calculated according to an algorithm to realize alarming, active intervention is carried out according to rollover degrees of the vehicle, and an active intervention control valve in an active intervention control is connected with a brake chamber through an electromagnetic regulating valve to realize decelerating braking so as to reduce rollover risks. By the method and the system, serious and catastrophic accidents can be avoided, mass death and casualty can be avoided accordingly, immeasurable economic loss can be avoided for our country and people, and life safety of drivers and pedestrians and unblocked roads are guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle chassis stability control, in particular to a control system for vehicle rollover prevention. Background technique [0002] With the rapid development of e-commerce and logistics in recent years, as well as the increase in the number of vehicles and the increasing power performance, the accident rate is also rising at a high speed. Road safety issues have attracted great attention in today's society. According to statistics, 70% of road safety accidents are caused by overloading and unbalanced loading of vehicles, and 50% of serious road traffic accidents with mass fatalities and injuries are directly related to overloading and unbalanced loading. Vehicle overloading and unbalanced transportation have caused huge losses to people's lives and property, and its indirect economic losses are even more difficult to estimate. [0003] At present, most of the patents on the vehicle anti-rollover warning system u...
