Abstract
An improved sidelighting arrangement, device and method of controlling sidelight illumination of a motor vehicle during cornering employing two sets of side lamps, one for each side of the vehicle. The sidelighting arrangement apparatus includes a steering wheel angle sensor mounted on the column of the steering wheel for detecting a change in steering angle, a turn indicator sensor for detecting actuation of the turn indicator, a microprocessor for outputting an electrical signal to selectively illuminate a set of side lamps mounted on the side of the vehicle for controlling illumination of the sidelights during cornering of the motor vehicle responsive to the steering wheel in actuation of the turn signal for improved visibility for the operator of the vehicle and for improved safety of operation thereof by providing notice to other drivers of the cornering condition of the vehicle.

15. A method of laterally projecting illumination from the side of a vehicle and automatically turning on sidelights of the vehicle on the side corresponding to the direction in which the steering wheel of the vehicle is being turned and a neutral position comprising the steps of:
-
a) providing a sidelighting arrangement for laterally projecting a section of illumination toward a selected area adjacent the side of the body of the vehicle on the side corresponding to the direction in which the vehicle is turning comprising two sets of sidelights each, mounted on opposite sides of the motor vehicle and each set comprising; i) light emitting means for emitting rays of light in a wide arc in a direction orthogonal to the axis of the vehicle body comprising lamp elements contained in a housing including mounting means; ii) a first side-lamp driver circuit means for energizing one or more lamp elements mounted on a first side of the vehicle; iii) a second side-lamp driver circuit means for energizing one or more lamp elements mounted on a second side of the vehicle; b) powering on the sidelight control device; c) establishing initial conditions for the control device; d) setting steering wheel rotation counters LEFT and RIGHT; e) providing that the sidelight control device enters the scan sensor mode; f) positioning the steering wheel in the neutral or "straight ahead" position; and g) initiating a turn, in particular a left turn, rotating the steering wheel counter-clockwise causing the magnet to pass by sensors #3 then #4, when the control unit senses the magnet at switch #4, having been last detected by switch #3, the control device acknowledges the initiation of a left turn by incrementing the left turn counter and when the control unit recognizes a left hand turn by incrementing the left turn counter, it immediately resumes processing; h) the operation of right hand turns is exactly opposite from that of left hand turns;
the right turn counter is incremented when the magnet is detected at switches #3 or #1 with the previous detection switch being #4 or #1 respectively; and
when the control unit recognizes a right hand turn by incrementing the right turn counter, it immediately resumes processing;i) when the magnet is not detected at all, the control device continues scanning the sensors until the magnet is detected; and
when the control device does not detect the magnet at any of the switch positions, the negative decision holds true, so switch scanning resumes;j) implementing the decision as to turn on one of the side-lights;
the amount of left rotation by comparing to the amount of right rotation and if they balance processing resumes back whereby the counters are returned in zero and all lights are turned off;
when the resulting difference is negative, then the wheel has been turned more clockwise than counter-clockwise and a right hand turn is in progress so the right hand light is turned on;
however, if the difference is positive, indicating more counter-clockwise than clockwise turning of the steering wheel, then a lift hand turn is in or still in progress so the right side lights are turned on;
wherein after updating the lights, the control device resumes operation.
