Motor vehicle curve driving assistance system and operation type

Abstract

The invention mainly relates to a motor vehicle curve driving assistance system and an operation type. The motor vehicle curve driving assistance system mainly comprises a frontend camera device, an image and data processor, a GPS (global positioning system) positioning device, a vehicle speed detection device, a wheel steering angle detection device, a vehicle-mounted multimedia display device and a system control processor, and is based on an image processing technique. The image and data processor of the system is used for determining whether a motor vehicle enters a curve or not through judging whether a complete obstacle background type exists in the driving road image of the motor vehicle or not, and analyzing and computing to obtain the site curvature radius data K. The motor vehicle curve driving assistance system has the advantage that when the motor vehicle approaches and drives through the curve, the related curve data and driving suggestions are accurately prompted to the driver through the multimedia display device, the driver, especially the primary driver, is assisted to safely and smoothly pass through the curve road, and the possibility of traffic accidents at curve is decreased.

Description

technical field [0001] The invention relates to a motor vehicle driving assistance system and its operation mode, in particular to a motor vehicle curve driving assistance system and its operation mode for monitoring curves based on image processing technology. Background technique [0002] Curve driving technology is an important driving technology for drivers. Whether an ordinary motor vehicle is stable when passing a curve is related to many factors, such as the curvature of the curve, vehicle speed, inclination angle of the curve, road friction coefficient and The weight and size of the vehicle itself. Although there are usually warning signs for sharp bends, or marked with speed limits, drivers sometimes do not pay attention to these warning signs or follow the marked speed limits and keep passing at high speeds, which may cause discomfort to vehicle passengers at least, and at worst in some In this case, the vehicle will lose control and a serious traffic accident wil...

Problems solved by technology

Although there are usually warning signs for sharp bends, or marked with speed limits, drivers sometimes do not pay attention to these warning signs or follow the marked speed limits and keep passing at high speeds, which may cause discomfort to vehicle passengers at least, and at worst in some In this case, the vehicle will lose control and a serious traffic accident will occur.

In view of this, some of the current motor vehicle auxiliary control systems also include some corresponding curve monitoring technologies, including using GPS signals, map databases, vehicle speed, vehicle yaw rate and steering angle to prompt the vehicle when the distance from the curve is different. The appropriate vehicle speed should be used in the position, but one of the problems with the above technology is that the accuracy of the calculation of the curvature data of the curve is not high, and the actual application cannot meet the needs of the driver.
