Turning radius display and vehicle speed alarm method for wheeled vehicle and device thereof

Abstract

The invention discloses a turning radius display and vehicle speed alarm method for a wheeled vehicle, and is characterized in that a displacement sensor is arranged on a turning oil cylinder on an axle, the displacement sensor is connected with a controller, a rotating speed sensor is arranged on an axle input shaft, the rotating speed sensor is connected with the controller, and the output ends of the controller are respectively connected with an alarm and a display; a displacement and a rotating speed, which are collected by the displacement sensor and the rotating speed sensor, are computed by the controller; a calculated vehicle speed V and a vehicle gravity center turning radius R are displayed on the display at any time, and maximum allowable values of a vehicle overturning moment and a slip force are input into a database, the computed result and the maximum allowable values are compared to make a judgment, when a calculated vehicle turning centrifugal force F is greater than the maximum allowable value of the slip force or a computed overturning moment M is greater than the maximum allowable value of the overturning moment, the controller sends a command to an alarm to give an alarm.

Description

technical field [0001] The invention belongs to the field of wheeled vehicle parameter display and alarm devices. Applied to wheeled chassis, vehicles equipped with hydraulic steering gear and steering cylinder for steering. Background technique [0002] Special vehicles such as snow plows and wheeled construction machinery often work in special working environments or special road conditions. Turning and walking, and even sharp turns are common. If the vehicle speed is low, work efficiency will be affected. If the vehicle speed is high and the turning radius is small, the outward centrifugal force of the vehicle will be relatively large. Coupled with the slippery or soft road surface, it is easy to cause the vehicle to slip outward or to overturn. trend, causing security risks.

AI Technical Summary

Problems solved by technology

If the vehicle speed is low, work efficiency will be affected. If the vehicle speed is high and the turning radius is small, the outward centrifugal force of the vehicle will be relatively large. Coupled with the slippery or soft road surface, it is easy to cause the vehicle to slip outward or to overturn. trend, causing safety hazards

[0003] Two states of poor driving safety: as attached figure 1 , the weight of the whole vehicle has a downward gravity G through the center of gravity. When turning and the speed of the vehicle is high, centrifugal force F will be generated. If F is too large, the car body will slide outward or even tip over.

[0004] At present, there is no warning display for the poor turning safety of vehicles. The safety of all kinds of vehicles is completely guaranteed by the driver's operating experience. When the road surface or construction site conditions are poor, it is easy to cause dangerous situations due to operational errors.
