WIPER CONTROLLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18436595 titled 'WIPER CONTROLLER
Simplified Explanation
The patent application describes a wiper controller that uses vector control to limit the q-axis current of a motor to zero in response to an overvoltage condition in the power supply.
- The wiper controller includes a driver with a three-phase bridge circuit and a controller.
- The controller switches the switching elements of the bridge circuit to control the motor's electrical conduction through vector control.
- The controller limits the q-axis current to zero when the power supply's voltage exceeds a preset overvoltage determination value.

Original Abstract Submitted
A wiper controller includes a driver and a controller. The driver includes a three-phase bridge circuit having switching elements connecting a positive electrode and a negative electrode of a direct current power supply to terminals of a motor. The controller switches the switching elements between an on-state and an off-state. The controller controls electrical conduction of the motor through vector control by switching the switching elements between the on-state and the off-state to limit a value of a q-axis current to zero, in response to that a detection voltage value of the direct current power supply exceeds a preset overvoltage determination value.
