Abstract

The invention belongs to the technical field of driving safety and discloses a driving assistance method and a driving assistance system. The system comprises an input module, an operation module, a logic judgment module and an output module. The input module is used for inputting a driving state value warning range, a driver's fingertip temperature x and a steering wheel holding force c of a driver's palm with a measured fingertip. The operation module is used for reading the steering wheel holding force c and the fingertip temperature x in the input module, substituting into a mathematical model determined according to a genetic programming method, and calculating a driving state value y. The logic judgment module is used for receiving a calculation result of the operation module, judging whether the driving state value y is in the driving state value warning range or not and sending control information if the driving state value y is not in the driving state value warning range. The output module is used for receiving control information sent by the logic judgment module and sending a driving signal. A measurement method which takes infinite norm as an optimization target is adopted for acquiring a driver's palm temperature and holding force related driving safety adaption value measuring model, and an optimal estimated value is acquired by calculation of the measuring model, the two capabilities of a driver can be reflected in real time according to the value, and accordingly a driving state can be monitored to avoid a dangerous driving state.

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...
