Abstract
An electronic throttle body control system (100) and method provides accurate control over a throttle plate (102) position via various functions. An ice breaking function detects whether there is ice blocking the path of the throttle plate (102) and vibrates the throttle plate (102) to break and remove the ice. A mechanical stop confirmation function that confirms a mechanical stop position each time the vehicle is turned on to ensure that adaptation values for the throttle plate (102) are calculated accurately. A miswiring detection function detects miswirings by detecting whether the actual movement of the throttle plate (102) is in a direction opposite to the setpoint target direction.
Claims11
An electronic throttle plate control system for a vehicle, comprising:
- a movable throttle plate;
- a drive unit that drives the throttle plate;
- and
- a controller that controls the drive unit and monitors the throttle plate position, wherein the controller checks whether the throttle plate is rotatable to a selected position when the vehicle is initially turned on and vibrates the throttle plate responsive to the throttle plate not being rotatable to the selected position.
A method of controlling a throttle plate in a vehicle, comprising:
- detecting an initial throttle plate position;
- moving the throttle plate in response to a request toward a setpoint;
- monitoring the direction of movement of the throttle plate with respect to the setpoint;
- and
- indicating a miswiring if the throttle plate moves away from the setpoint.
