Definitions

  • the invention relates to a motor vehicle for use on a public road and comprising a user-feedback system for signaling to the vehicle's operator that a pre-determined road speed has been attained.
  • the invention also relates to such a system.
  • Modern motor vehicles designed for use on the public road such as automobiles, trucks and motorcycles, are typically equipped with systems, electronically controlled by an onboard computer, that assist the driver or rider with safely operating the vehicle without unnecessary distraction.
  • systems electronically controlled by an onboard computer, that assist the driver or rider with safely operating the vehicle without unnecessary distraction.
  • Examples of such systems are anti-lock brakes, traction control systems, navigation aids, engine management systems, cruise control systems, etc.
  • Cruise control allows the vehicle to maintain a pre-set speed by means of automatically regulating (i.e., without the driver's intervention) the throttle depending on the actual road speed deviating from the pre-set speed.
  • cruise control Some drivers use cruise control to avoid violating legal speed limits. This type of use is feasible only on a long stretch of a highway, e.g., the German Autobahn, at times when there is hardly any traffic. In densely populated areas or in heavy traffic, cruise control is practically not useable as the vehicle's operator needs to adjust the road speed continually in order to adapt to changing circumstances such as traffic jams, traffic lights, merging traffic, changes in local legal speed limits, etc.
  • Law enforcement officers and road operators are increasingly more alert on catching drivers who violate the local speed limit, even those who exceed the speed limit by only a small amount.
  • the rationale for this is to force drivers to obey the traffic rules and to reduce the probability of a speed-related accident. Higher speeds leave less time for the driver to respond to changing circumstances, thus increasing the chance of getting involved in an accident. Also note that too low a speed can be dangerous as well, e.g., when a vehicle driving with a low speed is not expected by other drivers, or when overtaking traffic on a road with opposing lanes and without a center divider.
  • some cars enable the driver to pre-program one or more pre-determined speeds into the onboard computer.
  • the user-programmed speeds are, for example, representative of frequently occurring legal speed limits.
  • the computer Upon reaching a pre-programmed speed, the computer generates a signal that is made visible or audible to the driver through a suitable user interface such as a flashing dashboard light or a beeping sound. In this manner, the driver is audibly or visually alerted to the speed at which he/she is driving, thus providing a feedback mechanism without the driver needing to constantly keep an eye on the speedometer.
  • some personal navigation devices e.g., a range of products manufactured by TomTom
  • an audible or visible signal for alerting the driver to the current road speed is less then optimal, when the driver's visual and auditory senses are already fully occupied, if not overloaded, with operating the vehicle and navigating the traffic.
  • the visual signal in the form of a flashing light has to compete with other visual information that the driver has to process, e.g., the constantly changing traffic situations or visual directions of the onboard navigation system, the dashboard lights of the turn indicators or of low fuel level, etc.
  • the audible signal has to compete with the sounds of the engine, of the tires on the road surface, of nearby traffic, from the navigational guidance given via the vehicle's loudspeaker, from the car radio or music player, from passengers, wind noise, etc. Accordingly, an audible or visual speed-related signal may be distracting, confusing or may even not be noticed in time at all by the driver.
  • the inventor therefore proposes to use a speed-related warning signal of another modality and, moreover, to have it synergistically combined with the conventional user controls of the motor vehicle.
  • an embodiment of the invention relates to a motor vehicle, e.g., an automobile, a motorcycle, or a truck, for use on a public road.
  • the vehicle comprises a user- feedback system for providing feedback to the user about the current road speed.
  • the system comprises a controller for generating a control signal in dependence on a difference between a magnitude of an actual road speed of the vehicle and a pre-determined magnitude of the road speed.
  • the system further includes an actuator functionally coupled to the controller for, in response to the control signal, introducing a tactile signal in an accelerator device, such as the throttle pedal (“accelerator”) of a car or truck or the twist grip throttle on the handlebar of a motorcycle.
  • an accelerator device is part of the conventional user interface of a motor vehicle for user control of the actual road speed of the vehicle.
  • the functional coupling between the controller and the actuator sees to it that the actuator receives the control signal.
  • This functional coupling can be implemented in a wired manner or in a wireless manner, well within the capabilities of the skilled person.
  • the tactile feedback according to the invention uses a sensory channel of the driver different from the visual and auditory channels, thus avoiding a sensory overload of the latter. Also, the tactile signal is not going to be obscured or drowned by other tactile perceptions relevant for operating the vehicle, if any.
  • the functional integration of the actuator with the accelerator device stimulates the driver exactly at that part of the body that actively controls the vehicle's road speed.
  • the controller is functionally integrated with an onboard computer of the vehicle.
  • the functionality is then implemented by computer code that may be loaded into the onboard computer at the assembly plant of the vehicle, at the importer or at the local dealer, or even by the vehicle's owner via a data network such as the Internet as part of an after-market add-on.

Abstract

L’invention concerne une automobile, un camion ou une motocyclette doté d’un système de rétroaction à l’utilisateur comprenant un contrôleur et un actionneur. Le contrôleur génère un signal de commande en fonction d’une amplitude prédéterminée de la vitesse sur route du véhicule. Sous le contrôle du signal de commande, l’actionneur induit un signal tactile dans la pédale d’accélérateur ou dans la poignée des gaz. Ce signal tactile aide le conducteur ou le pilote à maintenir la vitesse prédéterminée afin de ne pas être en infraction avec une limitation de vitesse réglementaire locale.
