Early warning device for rollover of car

Abstract

The invention discloses an early warning device for rollover of a car. The early warning device comprises a horizontal acceleration early warning device, rollover detecting devices, a control device and a warning device, wherein a spring is respectively arranged between the two ends of a sliding block and a polished rod; when the two springs are in a balanced state, the sliding block is positionedat the middle part of the length direction of the polished rod; moving induction contacts in two groups of induction contacts are symmetrical by the central section in the width direction of a frame;the rollover detecting device comprises a supporting frame arranged at the lower side of the frame, rolling wheels and sliding rods; lower induction contacts are arranged at the lower sides of upperinduction contacts in sliding grooves; when the sliding rod slides in the sliding grooves, the upper induction contacts and the lower induction contacts are in contact and non-contact states. The early warning device for rollover of car disclosed by the invention carries out in-time early warning on different conditions of the car by double rollover detecting devices and is especially suitable forbeing installed on trucks so as to adapt to the operating states of the car under no load and full load.

Description

technical field [0001] The invention relates to a car rollover warning device. Background technique [0002] Car rollover is often due to the following reasons: 1. The lateral acceleration of the car is greater when turning, and this is also related to the turning radius of the car and the instantaneous speed of the car. When the turning radius is smaller, the moment the car rolls over The lower the speed; 2. The center of gravity of the car is higher. This situation is mainly for trucks. The position of the center of gravity of the truck is different when it is fully loaded and unloaded. The position of the center of gravity is low when it is unloaded. When the truck walks on a relatively complicated road condition, the overall shaking of the truck will cause the center of gravity of the truck to shift to the middle, and when the shift of the center of gravity reaches a certain level, the truck is prone to rollover danger. However, the current car rollover warning system o...

However, the current car rollover warning system often only analyzes the rollover risk by obtaining the lateral acceleration of the car when turning to give an early warning to the driver. The limitations of the vehicle rollover warning system cannot adjust the parameter comparison value of the lateral acceleration when the vehicle center of gravity changes
