Monitoring method for vehicle and vehicle

Abstract

The invention relates to a monitoring method for a vehicle and a vehicle so that a problem that the state of operating the steering wheel by the hands of the driver can not be determined accurately based on the existing monitoring scheme can be solved. The monitoring method comprises: acquiring a real-time torque value of a steering wheel of a vehicle; acquiring a real-time angular velocity valueof the steering wheel of the vehicle; and determining a driver confidence level of the vehicle based on the real-time torque value and the real-time angular velocity value and thus determining whetherthe drive is in a hand-off driving state based on the driver confidence level. According to the invention, the driver confidence level can be determined comprehensively based on the real-time torquevalue and the real-time angular velocity value; and thus the acting force on the steering wheel by the drive is used as a determination base and the angular velocity parameter capable of reflecting the rotating state of the steering wheel is also combined for determination. Therefore, whether the drive is in a hand-off driving state is determined accurately; and the effectiveness of monitoring isimproved and the error rate of monitoring is reduced.

Description

technical field [0001] The invention belongs to the field of vehicle technology, and in particular relates to a monitoring method for a vehicle and the vehicle. Background technique [0002] During the driving process of the driver, it is usually necessary to monitor the driving state of the driver in real time. For example, since the intelligent assisted driving technology has not yet reached the level of fully automatic driving, the main body of the vehicle is still the driver. Real-time monitoring of the driver's driving status can enable the driver to take over the driving work in time when the vehicle's assisted driving fails. Or when the driver is driving the vehicle for a long time or is not paying attention, real-time monitoring of the driver's driving status can remind the driver of unsafe behaviors and improve the safety factor of driving. Currently, judging whether the driver's hands are on the steering wheel can be used as a way to judge the driver's driving sta...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that it is difficult to accurately judge whether the driver's hand is out of the steering wheel in the existing detection scheme, the present invention provides a monitoring method for vehicles, and the monitoring method includes: Obtaining a real-time torque value of the steering wheel of the vehicle; obtaining a real-time angular velocity value of the steering wheel of the vehicle; based on the real-time torque value and the real-time angular velocity value, judging the driver's confidence of the vehicle, so that according to the Judging whether the driver is in the state of hands-off driving based on the driver's confidence
