System and method for improving vehicle driving behavior

Abstract

The invention relates to a vehicle driving behavior improving system. The vehicle driving behavior improving system is provided with an environmental perception module, a knowledge base module, a driving behavior algorithm module and a vehicle control system. According to environment information and knowledge information from the environmental perception module, an original brake pedal signal, an original accelerator pedal signal and an original steering wheel angle signal are optimized by the driving behavior algorithm module, optimized signals are obtained and compared with the original signals, an actual brake pedal signal, an actual accelerator pedal signal and an actual steering wheel angle signal are obtained and input into a brake system, a transmission system and a steering system correspondingly. According to brake torque, driving torque and a steering angle which are obtained from the brake system, the transmission system and the steering system correspondingly, a vehicle is controlled by the vehicle control system.

Description

technical field [0001] The present invention relates to vehicle control technology, more specifically to a vehicle driving behavior improvement system and improvement method that can reduce unnecessary fuel consumption and emissions during vehicle driving and help drivers develop good driving habits. Background technique [0002] Bad driving behavior will bring unnecessary fuel consumption and emissions, and even cause certain safety hazards. As a measure to improve bad driving behaviors, in the prior art, the vehicle fuel consumption curve is usually tracked to know whether bad driving behaviors exist. [0003] However, if you only track the fuel consumption curve of the vehicle and give voice prompts when the driver operates these driving behaviors, there will be the following two problems: [0004] (1) The improvement of driving behavior is very subjective. Just tracking the fuel consumption curve of the vehicle cannot essentially reduce unnecessary fuel consumption and ...

AI Technical Summary

Problems solved by technology

[0004] (1) The improvement of driving behavior is very subjective. Just tracking the fuel consumption curve of the vehicle cannot essentially reduce unnecessary fuel consumption and emissions during driving, and can only rely on vehicle prompts to improve driving behavior

[0005] (2) Unable to distinguish the rationality of driving behavior, especially the rationality of driving habits such as frequent parking, rapid acceleration, slamming on the accelerator, frequent lane changes and driving in curves, long-term low-speed driving, sudden braking and frequent speed changes, etc., even interfere with reasonable driving behavior
