System and method for monitoring and automatic undertaking of automobile hand-released driving

Abstract

The invention provides a system and method for monitoring and automatic undertaking of automobile hand-released driving. The system comprises a steering wheel torque sensor, a processor, a reminding unit and a control unit, wherein the steering wheel torque sensor is used to monitor a steering wheel torque value of a vehicle; the processor is used to receive torque value information monitored by the steering wheel torque sensor, judge whether corresponding hand-released driving conditions are satisfied according to the torque value information and send out a corresponding control signal according to the judgment result; the reminding unit is used to receive the control signal and send out corresponding reminding information; and the control unit is used to receive the reminding information, judge whether corresponding automatic undertaking conditions are satisfied according to the reminding information and start an automatic undertaking mode according to the judgment result. The system and method have the advantages that a driver can be reminded after the hand-released driving; the system will automatically undertake the vehicle if reminding fails and a danger alarm lamp can be turned on automatically; braking and parking can be achieved safely according to traffic situations, and a function of initiative vehicle parking can be achieved.

Description

Technical field [0001] The present invention relates to the field of automobile technology, and in particular to a system and method for monitoring and automatic takeover of an automobile off-hand driving. Background technique [0002] In daily life, the driver often encounters situations such as long-term fatigue driving, drowsiness, the driver answering the phone, replying to text messages, the driver’s central control, the driver’s lack of concentration, etc. The vehicle will often be in the driver’s hands-off state at high speeds. Driving without hands on roads is very dangerous and can easily cause accidents. However, current prevention management facilities have many limitations. [0003] At present, the existing schemes of major automobile OEMs at home and abroad are mainly based on the prediction of vehicle trajectory, analyzing and judging whether the driver is in a state of fatigue, or judging whether the driver is fatigued according to the degree of closed eyes and clos...

Problems solved by technology

[0004] For example: some systems use GPS to monitor vehicles, but most of them are used in vehicle entry and exit management systems, and they do not really monitor vehicles driving on the road, and the cost is expensive; some systems use facial expression recognition systems to judge the driver's spirit The disadvantage is that the system is complicated and the cost is high; some sys...
