Method and system for controlling vehicle

Abstract

The invention discloses a method and a system for controlling a vehicle. The method and the system are applied to a vehicle which is at least provided with an acceleration pedal and a deceleration pedal. A signal sensor, a position sensor and a condition sensor are used for sensing a control signal of the acceleration / deceleration pedal, a mechanical position of the acceleration / deceleration pedal and various travelling conditions of the vehicle respectively; a central processing unit is used for analyzing the control signal, the mechanical position and the travelling conditions which are sensed so as to determine various operating conditions of the vehicle; therefore, the central processing unit can be used for correspondingly controlling the vehicle according to the determined various operating conditions when a preset automatic operation condition is established, so that the travelling safety of the vehicle is improved.

Description

technical field [0001] The present invention relates to a vehicle control method and system, in particular to a vehicle control method and system for performing safety control on vehicles by analyzing various vehicle state information. Background technique [0002] As the public pays more and more attention to driving safety, vehicle manufacturers are also investing more and more research and development efforts in various electronic technologies to improve driving safety, such as active detection of vehicles and surrounding obstacles. Electronic distance detection technology, headlight steering technology to increase the driver's night vision range, airbag technology to reduce the impact of the driver in the event of an accident, and electronic braking technology to improve braking efficiency Wait. [0003] What is most closely related to our daily life is various electronic braking technologies to improve braking efficiency, such as Brake Assist System and Antilock Brake ...

AI Technical Summary

Problems solved by technology

[0004] However, even though most of today's vehicles are equipped with various electronic braking technologies to improve braking efficiency, major accidents caused by vehicles not being able to decelerate smoothly or abnormally crashing still continue to occur in our daily life

The reason is that, in addition to the electronic braking technology configured in the vehicle being too complex, causing the driver to fail to perform appropriate operation steps smoothly and easily, the more common reason is that the accelerator pedal and / or deceleration pedal of the vehicle have Sudden mechanical failure, which leads to the inability of the electronic braking system to perform its functions smoothly

For example, if the accelerator pedal of the vehicle fails to rebound smoothly, the driver will often be too nervous to properly operate the electronic braking technology equipped with the vehicle to decelerate, which will lead to accidents, resulting in severe loss of life and property

Furthermore, the existing vehicle control system does not monitor various types of vehicle status information to determine whether the vehicle is in an unexpected state or an abnormal state, so it is impossible to control the safety of the vehicle

On the other hand, due to the different habits of each driver, the abnormal state of the vehicle that occurs is also different. If a fixed (single judgment standard) control method is used, it is difficult to meet the needs of everyone.
