Abstract

Aggressive driving causes many fatal accidents every year around the world. There is a great need to control aggressive driving. Additionally vehicle fleet owners, such as transportation trucks and vans, taxi cabs, etc., and operators may have a number of concerns as to how the vehicles are driven in the course of their daily operations. The steering wheel includes a plurality of pressure sensors distributed along its circumference which are able to determine the pressure the vehicle's driver's hands are doing on the steering wheel itself. If the pressure on the steering wheel by the hands remains high that will indicate that the driver continues operating the vehicle in a stressed condition, such as anger. The present invention detects that situation and responds accordingly. The processing unit receives the measurement from each sensor and compares to the threshold established. If the measurement exceeds the pre-established threshold and it is maintained at that level during a certain period of time the processing unit transmits a signal to the external unit. The time period frame is established to be able to consider short time length high pressure as reaction to sudden manoeuvres such as sudden brake or risky manoeuvres to avoid collisions. Certain physical symptoms, in particular the muscular tension at the hands of a vehicle operator can be detected to identify aggressive behaviour while operating a vehicle.

Aggressive driving detection system

Aggressive driving causes many fatal accidents every year around the world. There is a great need to control aggressive driving. Additionally vehicle fleet owners, such as transportation trucks and vans, taxi cabs, etc., and operators may have a number of concerns as to how the vehicles are driven in the course of their daily operations

    The present idea provides a simple indicator of the driver's stress which may cause an aggressive attitude in his driving by measuring the intensity and duration of the pressure of his hands on the steering wheel.

    Muscle tension is typically caused by the physiological effects of stress When the body is stressed, muscles tense up. Muscle tension is almost a reflex reaction to stress. With sudden onset stress, the muscles tense up all at once, and then release their tension when the stress passes. Vehicle drivers may experience this in some situations such as a sudden speed slow down of the vehicle just ahead or an inadequate manoeuvre of a nearby vehicle which may force the driver to step on the break suddenly and his arms and hand muscles tense up producing a higher pressure on the steering wheel surface.

    As the dangerous situation passes by the tension in the hands and arms returns to normal as the stress passes.

    If the pressure of the hands on the steering wheel remains high that will indicate that the driver continues operating the vehicle in a stressed condition, such as anger. The present idea detects that situation and responds accordingly.

    The steering wheel 100 includes a plurality of pressure sensors distributed along its circumference which are able to determine the pressure the vehicle's driver's hands 101 and 102 on the steering wheel itself.

    Pressure sensors are uniquely identified 201a, 201b,etc. and are connected to processing unit 203 by means of a wired or wireless connection.
