ABSTRACT:
Windshield wiper systems are commonly used on vehicles that must operate out-of-doors. In systems employing two or more wiper elements, each operating from an individual wiper motor, some mechanism must be employed to prevent out-of-sync operation from causing the wiper elements to collide if they operate in an overlap area. The instant wiper system includes first and second electric motors each drivingly connected to a respective windshield wiper element. Switching devices selectively controllably provide electrical power to the motors in response to receiving respective motor control signals. Synchronizing devices provide first and second synchronizing signals in response to the respective wiper elements being positioned at corresponding predetermined cycle start locations. A logic circuit controllably produces the motor control signals in response to receiving the respective synchronizing signals.
