Automatic transmission-based emergency running mode control method

Abstract

The invention relates to an automatic transmission-based emergency running mode control method, which has high safety and reliability, is particularly suitable for special drivers such as old people and women with relatively slow response, and solves the technical problems that the driving mode in the prior art has poor safety and low reliability, the special drivers such as old people and women cause major safety accidents due to unexpected conditions in the driving process, the drivers and riders is endangered directly if the major safety accidents are serious, and the like. The method comprises the following steps of: setting n different reference stress values on a control unit to form n+1 reference stress value comparison sections; comparing a stress value G detected by a force sensor on a steering wheel with each stress value comparison section to determine the comparison section to which the stress value G belongs; and selectively executing enforced stop or downshift operation or current state maintenance by using the control unit according to the current shift.

Description

technical field [0001] The invention relates to a control method of an automobile driving mode, in particular to a control method of an emergency driving mode based on an automatic transmission with good safety and high reliability. Background technique [0002] With the increasing popularity of automobiles, automobile technology has developed rapidly, and the users of automobiles are becoming more and more diverse. In addition to the elderly, there are also elderly people and women. Different users have different requirements for automobiles, such as power performance, Acceleration performance, energy consumption, etc. In addition, people pay more attention to the safety performance of cars, especially for special driving groups such as the elderly and women. When they encounter emergency situations during driving, they often show Tense actions such as holding the steering wheel tightly and being at a loss can easily lead to major safety accidents, and in serious cases dire...

AI Technical Summary

Problems solved by technology

[0004] The present invention mainly provides a control method based on an emergency driving mode of an automatic transmission with good safety and high reliability, which is especially suitable for special driving groups such as the elderly or women who respond relatively slowly, and solves the problems existing in the prior art. The driving mode is poor in safety and low in reliability, especially for special driving groups such as the elderly or women, who are prone to major safety accidents during driving due to unexpected situations, and directly endanger the lives of drivers and passengers in severe cases.
