Embodiment

[0037] Embodiment: a kind of automobile turning anti-rollover system of this embodiment, such as figure 1 As shown, it includes a wheel deflection measuring instrument 1, a force sensor 2, a vehicle speed controller 3, an alarm 4 and an angular velocity measuring instrument 5. The wheel deflection measuring instrument is installed on the left front wheel of the vehicle to measure the deflection angle θ of the left front wheel during the instantaneous turning process of the vehicle 1 The size and angular velocity measuring instrument is installed on the front wheel of the vehicle to measure the instantaneous angular velocity of the front wheel of the vehicle. There are four force sensors, which are respectively installed at the axle centers of the four wheels. The wheel deflection measuring instrument, force sensor and alarm are all connected with the vehicle speed control electrical connection. The alarm includes a sound alarm and / or a light alarm, the sound alarm is installe...

Abstract

An automobile cornering rollover prevention system comprises a speed controller, a wheel deflection measuring instrument mounted on a front wheel of the automobile, force sensors mounted on axis positions of four wheels, and an angular speed measuring instrument and a speed controller mounted on the front wheel of the automobile, and the wheel deflection measuring instrument, the angular speed measuring instrument and the force sensor are all electrically connected to the speed controller. The speed controller is connected to a brake system of the automobile, so that the speed can be intelligently reduced through the brake system. When a driver changes θ1 according to a road condition, the speed controller may calculate a critical radius in real time and then compare the speed and give a command in real time for controlling the speed, so that the speed is maintained in an ideal range.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method and system for preventing rollover when turning and effectively improving safety. Background technique [0002] With the continuous expansion of urbanization, the number of family cars is increasing day by day, resulting in a large area of ​​road coverage, whether it is ordinary lanes or elevated roads, there are all kinds of curves, large and small. As we all know, everyone has a habit when driving a corner. They will first slow down to the ideal state and then turn slowly. When the corner is out, step on the accelerator to accelerate. Little do they know that this habit will more or less increase the fuel consumption of the car, and the brake pads will also increase the wear and tear, which will be a very considerable expense in the long run. In addition, when drivers travel on these roads every day, they will inevitably suffer from visual fatigue, and cannot correctly ...
