Problems solved by technology

However, the existing methods for characterizing the driving state cannot directly and effectively characterize the energy storage and utilization of brain cells and sympathetic nerve cells
Therefore, the existing methods for characterizing the driving state generally have the problems of excessive time lag and low accuracy when performing early warning of the driving state

Embodiment Construction

[0065] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0066] Such as figure 1 As shown, the present invention is provided with an input module 1, an operation module 2, a logic judgment module 3 and an output module 4. Among them, the input module 1 mainly receives peripheral input signals such as the fingertip temperature x detected by the temperature sensor and the grip force c of the steering wheel detected by the pressure sensor, and provides the received input signal to the calculation module 2, and provides the logic judgment module 3 with The early warning range of blood sugar concentration is used as a benchmark for comparison. The calculation module 2 mainly reads the grip force c of the steering wheel and the fingertip temperature x in the input module 1, and substitutes them into the measurement model established by the genetic programming method to calculate the driver's blo...

Abstract

The invention discloses a method and system for assisting driving, belonging to the technical field of driving safety, which includes an input module: input driving state value warning range, driver's fingertip temperature x and the driver's grip force of the palm holding the steering wheel measured by the fingertip c; calculation module: read the steering wheel grip c and fingertip temperature x in the input module, and substitute them into the mathematical model established by the genetic programming method to calculate the driving state value y; logic judgment module: receive the calculation result of the calculation module, and judge the driving Whether the state value y is within the early warning range of the driving state value; if it is not within the early warning range of the driving state value, send control information; output module: receive the control information from the logic judgment module and send out a driving signal. The present invention adopts the measurement method with the infinite norm as the optimization target to obtain a measurement model of the driving safety fitness value related to the driver's palm temperature and grip strength, and obtains an optimal estimated value through the calculation of the measurement model, the value These two abilities of the driver can be reflected in real time, and then the driving state can be monitored to avoid the occurrence of dangerous driving states.

Description

[0001] This patent application claims the priority of the Chinese invention patent application with application number "201610438695.0", titled "A Control Method and System for Assisting Driving of Diabetics", and application date "2016.06.20". technical field [0002] The invention belongs to the technical field of driving safety, and in particular relates to a driving assistance method and system. Background technique [0003] During the driving process, the driver will experience dangerous driving states such as blurred vision, fatigue, and unresponsiveness to varying degrees. In the prior art, it is one of the important methods to reduce the occurrence of traffic accidents to characterize the driving state in a specific way and to accurately and quickly identify the dangerous driving state. [0004] At present, there are four main methods to characterize the driving state: (1) Characterize the driving state based on the driver's behavior characteristics (such as: head mo...
