Abstract

The invention provides a rollover prevention system of a vehicle. The rollover prevention system of the vehicle comprises an electronic control unit, and further comprises a motor and an acoustic surface wave transverse acceleration sensor which are connected with the electronic control unit; the acoustic surface wave transverse acceleration sensor is used for detecting transverse acceleration generated due to centrifugal force during vehicle steering, and the direction of the transverse acceleration is the direction of the centrifugal force borne by the vehicle; and during vehicle steering, the acoustic surface wave transverse acceleration sensor detects the transverse acceleration, the electronic control unit judges whether the vehicle has the rollover tendency or not according to the transverse acceleration, and the motor controls a steering wheel of the vehicle according to the rollover tendency.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile rollover prevention system. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles is increasing day by day. As the most used means of transportation, on the one hand, it provides great convenience for people's daily travel, and on the other hand, it also brings a huge threat of traffic accidents to personal safety. Among them, the car is often easily affected by the centrifugal force when turning at high and low speeds. Once the car is turning too fast and over-steering, it is subject to a large centrifugal force, and it is extremely prone to the danger of overturning. If it is understeering, it is extremely easy to rush out of the runway , causing serious traffic accidents. [0003] In the current prior art, the anti-lock braking system (ABS) is more commonly used to prevent the car from rolling over du...
