Definitions

  • the present invention generally relates to headlights on vehicles. More specifically, the invention relates to cornering lamps on vehicles which allow a driver to see beyond the projection area of the regular headlamps when making a turn.
  • the light beams projected by the modem headlights are directed straight forward to optimise utilisation of the lamps and maximize the visibility of the driver as the driver’s vision is oriented forward most of the time. Turning manoeuvres are therefore critical as the visibility of the driver is limited in the direction where they want to turn.
  • Various safety measures are incorporated in vehicles to avoid causing an accident such as turning indicator lamps and braking indicator lamps in conspicuous places so that drivers in vehicles around the vehicle making the turn are sufficiently warned of the fact.
  • headlamps provided in commercial vehicles come with a low beam as well as a high beam function. While the low beam function can illuminate the immediate path of the vehicle, the high beam function on the other hand provides a comprehensive illumination of the surrounding environment. However, it is at the detriment of other road users, especially the drivers of preceding and oncoming vehicles, who get dazzled.
  • the low beam does not dazzle other road users, but has the obvious disadvantage in illuminating the path of the vehicle being driven.
  • the high beam function can only be used very rarely. Therefore, there is a need to provide headlamp assemblies which provide better illumination than the conventional low beam function, but at the same time do not dazzle other road users like the high beam function.
  • Document US 10023103 discusses and discloses a system and method of controlling and distribution of illumination when a 2-wheeler vehicle is banking in order to control and maintain a pattern of light generally horizontal during the vehicle bank.
  • This system is based on the principle that when yaw axis data is zero, the calculated bank angle can be set to zero. Thus, this is achieved by calculating the roll or pitch of the vehicle when in motion, with the condition that the yaw is not within certain limiting conditions.
  • An apparatus comprising an inertial measurement unit is provided to sample the yaw rate data, and when the predetermined boundary conditions are exceeded.
  • Document US9802529 further discusses and discloses a predictively controlled cornering light in a 4-wheeler vehicle.
  • the headlights are provided with a pivoting means and a monitoring system which monitors the roadway and / or lane in front of the vehicle and generates roadway data to drive the pivoting means for setting the headlights at the appropriate position. Further, a model of the headlamp projection on the roadway is made with the data, and the lamp is further rotated to minimize the deviation between the model and the actual roadway data.
  • Document EP0842817 further discusses and discloses the control and distribution of illumination in an automatically actuated cornering lights system for 2-wheelers.
  • the system measures the leaning of the two-wheeler vehicle while cornering and its impact on the light throw on the road.
  • a light distribution screen is then used to control the intensity of light in order to achieve better visibility in cornering, and at the same time, oncoming traffic is not dazzled by the lights when the vehicle is moving straight.
  • this document doesn’t discuss or disclose any control strategy or how to determine the vehicle turning radius to automatically actuate the cornering lamps.
  • the headlamps being provided are configured to project a beam of light straight forward, as that is the direction in which the driver’s vision would be oriented most of the time while driving.
  • the driver When turning the vehicle, the driver would look toward the direction in which he/she intends to go.
  • the forward projected lights do not turn along the direction of the intended turn, and the dim glow and glimmer from the headlamps that scantily illuminate the driver’s intended path are insufficient for safe driving conditions.
  • modem headlamps come with low and high beam options. While low beams are effective in illuminating the area immediately ahead of the vehicle, high beams are effective in projecting a beam of light straight ahead with the purpose of illuminating an area further ahead of the current position of the vehicle, so that the driver has ample time to react when moving forward. This however, does not solve the problem of headlamps being ineffective when navigating a turn, especially a tight turn where vision is restricted beyond the turn. In an unlit or a dimly lit road, this could result in accidents.
  • Automotive manufacturers try to solve this problem by providing extra lamps, in addition to those already disposed in the headlight assemblies. These lamps are specifically designed as cornering lamps. These lamps are actuated when making a turn, in the direction of the turn, and are not generally otherwise used. While some earlier designs incorporated a manual switch to activate these lamps, they are generally automated. This is generally done by calculating the turning radius of the vehicle, and then directing the light towards the required direction, i.e., the direction of the driver’s vision.

Abstract

La présente invention concerne de manière générale un procédé et un dispositif d'actionnement d'un ou de plusieurs phares de virage sur un véhicule à deux roues (100). Le procédé consiste à déterminer la vitesse de roue (302) et l'angle de direction (202) du véhicule (100), qui sont utilisés pour déterminer un rayon de rotation (Rt) par recherche d'une base de données de rayon de rotation prédéfinie (506) dans la mémoire (505) de l'unité de commande (102) par rapport aux valeurs de vitesse de roue et d'angle de direction ; qui sont triés dans l'une d'une pluralité de plages de limitation prédéterminées (408) du rayon de rotation (Rt). La plage de limitation est ensuite utilisée pour déterminer les paramètres d'actionnement du ou des phares de virage (410). Une base de données de rayon de rotation (506) est stockée dans l'unité de mémoire (505) de l'unité de commande (102), laquelle est accessible par le processeur (504) pour déterminer le rayon de rotation (Rt). Le processeur (504) détermine les paramètres d'actionnement de phare.
