Electronic intelligent turn signal control system
First Claim
1. An intelligent turn signal control system for turning off a turn-signal left on in a vehicle having turn-signal control and turn signal indicator, which includes:
- sensors for providing differential wheel movement signals on the vehicle;
a computer operably disposed on a vehicle and connected to the turn signal control to receive a signal indicating that a turn-signal has been activated and transmit a turn-off signal to the turn-signal indicator upon having determined a turn completion, said computer operably connected to said sensors and having software for determining when a turn-signal is activated, and for manipulating sensed differential wheel movement signals to determine when a predetermined differential wheel movement has occurred indicating a completed turn.

Abstract
An intelligent turn signal control system for turning on and off left and right turn signals in a vehicle includes a computer, such as an antilock braking system computer, with programmed software operably disposed on a vehicle, a driver interface switch assembly as input to the computer. Two or more wheel speed sensors transmit differential wheel movement data as input to the computer, a circuit drives turn signal indicator lamps from conditionally computed output data from the computer to turn on and off turn signals in a situation-appropriate manner. Upon turn signal indication intent data input from the driver, extensive travel and turn data is computed, including yaw rotation and steering system position to turn off or cancel the turn signal at the appropriate point.

19. An intelligent turn signal control system for turning on and off vehicle left and right turn signal and turn related indicator lamps, which includes:
-
a computer operably disposed on a vehicle and having software to control turn signal on/off status;
at least two sensors for providing differential wheel movement signals to said computer;
