Embodiment 2

[0039] This embodiment provides a rollover warning control system. In addition to the rollover warning function, it can also realize the rollover active intervention function, so as to ensure that the vehicle is actively adjusted to avoid rollover when there is a risk of rollover. . then, if image 3 As shown, in addition to the perception module, central controller and early warning module, the control system also includes an active intervention module to achieve active intervention on the vehicle to avoid rollover. The active intervention module can realize at least one of the functions of vehicle deceleration, active steering body control assistance, and body posture control. Therefore, the active intervention module includes: AEBS, body posture active control suspension system (referred to as active suspension) and body At least one of the stability control systems (that is, the ESP system), of course, the more equipment included, the safer the vehicle will be in the acti...

Abstract

The invention relates to a rollover warning control method and system. The method includes the steps: firstly, acquiring road curvature information of a front set distance and current vehicle speed information, calculating the lateral acceleration of a vehicle after corresponding time according to the vehicle speed information and the road curvature information and taking the lateral accelerationas predicted lateral acceleration; secondly, judging the size relationship between set alarm threshold acceleration and the actual lateral acceleration and the predicted lateral acceleration of the current vehicle, and giving an alarm according to judgment results and corresponding data. The rollover warning control method is a prediction method and has perceptiveness, rollover risks caused by a front road are predicted before the vehicle reaches the front road, and the rollover risks caused by the severe degree of a front working condition is estimated in advance. When existence of the rollover risks is estimated, an alarm is given to remind a driver of corresponding operation, so that potential risks are controlled, the potential rollover risks are further avoided, rollover can be maximally avoided, and safety running of the vehicle is ensured.

Description

technical field [0001] The invention relates to a rollover early warning control method and system. Background technique [0002] Rollover accidents are extremely harmful. How to minimize the probability of rollover accidents is an important direction of automotive technology research. At present, domestic and foreign OEMs generally reduce the vehicle's cornering stress by limiting the height of the center of mass and using stabilizer bars. The roll angle of the vehicle body can suppress the probability of vehicle rollover, but this measure cannot be actively controlled according to the driving of the vehicle, so it cannot reduce the probability of rollover accidents to the greatest extent. [0003] Existing passive suspensions have no additional energy, and cannot maximize rollover safety; existing technologies for rollover safety are mostly a single implementation plan, and there is no systematic and comprehensive active safety control system. For example: the Chinese pat...
