Abstract

As vehicle collision avoidance systems are improving at a rapid rate, vehicles are gaining the ability to provide data to drivers about the state of the road around them. Traditionally, information has been conveyed to drivers through either aural cues (series of tones, synthesized voice, etc.) or visual displays. This extra information can be distracting to drivers, however, or may take the driver's attention away from the road; i.e. in order to glance at the instrument panel. Audio is not necessarily any better as an abstract series of tones may not be intuitive to the driver, voice may be competing with other noises in the vehicle, or may be ignored by the driver altogether. Proposed is a haptics-enhanced steering wheel and pedal system to provide the driver with feedback on potential road hazards and dangerous manoeuvres. This enhanced control system provides the driver feedback in a number of ways: mild directional vibration in the steering wheel; i.e. if the vibration is on the left-centre of the wheel, there is a vehicle in a driver's left blind-spot; gentle counter-force to the driver's motion of the wheel. This is calibrated to allow the driver to overdrive the force easily, but is noticeable enough to alert the driver that they may be making an error in judgement; and, brake and gas pedals with variable resistance. These pedals do not operate any differently than standard pedals; the same distance travelled by the pedal brakes or accelerates the same amount, however the feel of the pedal will immediately inform the driver of road conditions or alert them to the actions of other drivers. As these actions are all part of the mechanics of driving a vehicle, these feedback systems do not require attention to be diverted elsewhere, and allow for the driver to immediately interpret their current driving conditions and surroundings. This system is enhanced with vehicle-to-vehicle communications which allow for shared information between drivers, such as estimations of driver actions, and also allows for distancing and location between vehicles to be shared. Therefore, vehicles can detect each other and communicate their relative locations and operating characteristics to warn each other about potentially dangerous driver actions (such as beginning to change lanes while a vehicle is in their blind spot).
