Definitions

  • the present invention relates to a vehicle turn indicator system.
  • Vehicle turn indicator systems include turn indicator levers which are used to activate and deactivate left and right indicator lamps of a vehicle.
  • the indicator levers include a sophisticated mechanical ratchet mechanism which is used to deactivate the indicators as the vehicle steering wheel is turned back towards a centre position after a turn has been completed.
  • the mechanical ratchet mechanism also includes a latching mechanism which physically locks the lever in a turn position to ensure the left or right indicators remain on whilst a turn is completed.
  • a vehicle turn indicator system including: a turn indicator switch; left and right turn indicators; a steering angle sensor; and signal processing means responsive to the state of said switch for activating said indicators, and responsive to said steering angle sensor for deactivating said indicators.
  • Figure 1 is a block diagram of a vehicle turn indicator system.
  • a turn indicator system 2 as shown in Figure 1 , includes a turn indicator lever switch
  • the indicator lever 4, the steering column module 6 and the steering angle sensor 10 are mounted in the vehicle's steering wheel assembly.
  • the turn indicator lever 4 is connected to the steering column module 6 and both the steering column module 6 and the steering wheel sensor 10 are connected to body electronics module 8 by a multiplexed serial bus which forms a local area network (LAN) in the vehicle
  • the body electronics module 8 is able to receive signals from other parts of the vehicle, such as a vehicle speed sensor 16 and a brake sensor 18, and transmit activation signals to parts of the vehicle, such as the left and right indicator lamps 12 and 14, using the LAN or dedicated wires forming part of wiring looms of the vehicle
  • the turn indicator lever 4 is a self-centring lever with four similarly spaced switching positions LI , L2, Rl and R2 where two each are disposed on opposite sides of a centre position 20 of the lever 4
  • One side is tor Rl and R2 for the right indicator 14 and the other side is for LI and L2 for the left indicator 12, as shown in Figure 1
  • Mild actuating pressure moves the lever 4 to the first positions Rl and LI , whilst stronger pressure will move the lever to the second positions R2 and L2
  • a detent action at the first position Rl or LI provides tactile feedback to a driver that the first position Rl or LI has been reached
  • the lever 4 does not include a mechanical ratchet or a latching mechanism, as is the case tor normal indicator levers, and on releasing the lever 4 it will return immediately to the centre position 20
  • the lever 4 includes switches which are activated for each of the positions LI , L2, Rl and R2, and the switches can be implemented using moulded silicon conductive pads Alternatively the switches may be implemented
  • the steering column module 6 encodes the state of the switches, which represents whether the lever 4 has been placed in one of the positions LI , L2, Rl or Rl , together with the state of other switches on the steering wheel column, into serial bit stream tor transmission to the body electronics module (BEM) 8 Upon a serial bit stream request from the BEM 8.
  • BEM body electronics module
  • the steering control module 6 transmits the state of all switches to the BEM 8 Alternatively the steering control module 6 may transmit only the status of the switch that has changed state, along with a switch identifier
  • the steering angle sensor 10 converts the physical angle of the steering wheel from a predetermined position into a number that is transmitted to the BEM 8
  • the steering angle sensor 10 may already be provided as part of a vehicle dynamic control system which is used to effect brake control during turning as an extension of an ABS system This system is 5 included in Mercedes Benz vehicles and is described in a Society of Automotive Engineering (SAE) Technical Paper, No 950759, Advancements in ABS/TCS and Brake Technology SP-1075
  • the sensor 10 may consist of a plastic moulded annular disk magnet with a number, such as 30, of radially arranged north-south pole transitions Two magnetic sensors, such as solid state hall effect sensors, can be offset from each other by an appropriate
  • the senor 10 amount to generate a two-bit grey coded quadrature signal which can be ted to the steering column module 6 to determine both the direction and magnitude of rotation of the vehicle steering wheel This data can then be transmitted serially to the BEM 8 to allow the calculation of the absolute steering wheel angle
  • the sensor 10 may include an optical chopper disk with alternating radially transmissive and opaque sections
  • the body electronics module 8 controls activation and deactivation of the indicators
  • the BEM 8 may also use data from other vehicle sensors 16 and 18 When the
  • BEM 8 receives data that the lever 4 has been moved from the centre position 20 to the LI or Rl position, the BEM 8 causes the following the occur
  • 25 or right indicator 12 or 14 will flash tor as long as the lever 4 is held in the LI or Rl position It the lever is held in the LI or Rl position for less than one flash period, the left or right indicator 12 or 14 will produce one full flash
  • the BEM 8 determines the steering wheel angle which then needs to be traversed before the left or right indicators 12 or 14 can be subsequently deactivated
  • the BEM 8 uses the angle data provided by the steering angle sensor 10 to determine the current angle, when the lever 4 has been moved to L2 or R2, and the deactivation angle Therefore the left or right indicator 12 or 14 will be held in an activated state until the BEM 8 receives data from the steering angle sensor 10 indicating that the deactivation angle has been reached
  • the angle information provided may be provided by the steering column module 6 Alternatively the BEM 8 may use current and historical values of vehicle speed from the speed sensor 16, brake pedal activation information from the brake sensor 18 and steering wheel angle to determine when the indicators 12 or 14 should be deactivated
  • the vehicle turn indicator system 2 described above is particularly advantageous as it does not require use of the complex and relatively expensive mechanical ratchet and latching mechanism used in existing turn indicator levers
  • a simpler self-centring turn indicator lever 4 can be employed allowing cost savings to be made, which are even more significant in a vehicle which already includes a steering angle sensor 10 as part of a vehicle dynamic control system Activation and deactivation of the turn indicators is determined on the basis of electronic information provided concerning steering wheel position instead of the standard mechanical and ratchet mechanism employed in existing turn indicator levers
