An unmanned driving system with anti-rollover function

Abstract

The invention discloses an unmanned driving system with anti-rollover function, which includes an anti-rollover actuator, a control module, a gas generation module and a sensor unit. The anti-rollover actuator is symmetrically installed on both sides of the vehicle frame and includes an air chamber The casing and the air chamber casing are fixedly installed on the vehicle frame. The sliding box is slidably arranged in the air chamber casing through the horizontal sliding channel. The transmission mechanism moves in translation, and the translation transmission mechanism is also connected to one end of the transfer link and the air injection opening and closing mechanism to drive them to move together with the sliding box. The support injection mechanism is arranged on the air chamber shell, and the gas generating module is arranged in the sliding box. The present invention achieves a better anti-rollover effect than the prior art through continuous execution of multiple anti-rollover actions. At the same time, the actual lateral extension length of the injected support is small, reducing the probability of secondary damage and preventing rollover. The effect is also better.

Description

technical field [0001] The invention belongs to the field of automatic driving systems and relates to an unmanned driving system with rollover prevention function. Background technique [0002] At present, in the field of automatic driving technology, active suspension, differential braking, active steering, chassis integrated control and other methods are mainly used to adjust the roll angle of the vehicle to prevent rollover accidents that may be caused by turning. Among them, it is necessary to detect the lateral acceleration and roll angle and calculate the lateral load transfer rate as the judgment index for starting each anti-rollover actuator. However, when the wheels are laterally hindered by low terrain obstacles during the turning process, the lateral load transfer rate will increase sharply. At this time, an actuator that can quickly apply the righting moment opposite to the rollover direction is required to Respond immediately when the measured roll angle reache...

Problems solved by technology

[0005] The purpose of the present invention is to provide an unmanned driving system with anti-rollover function to solve the lack of unmanned driving systems in the prior art that integrate multiple anti-rollover mechanisms such as air injection, center of gravity adjustment and auxiliary support, resulting in It is difficult to arrange the anti-rollover mechanism, and the auxiliary supporting support in the anti-rollover process is prone to occur when the supporting point is too close to the rollover fulcrum or the lateral extension distance is long, which affects the reliability of the anti-rollover and the safety of the car in the future. question
