Abstract
A vehicle includes a transmission, hood, DC energy storage system, power inverter module, high-voltage AC device, sensors, and a controller. The sensors are operable for determining input signals and conditions, including a position sensor operable for detecting an open/closed position of the hood. The controller is programmed to execute a method for preventing access or exposure to the AC-side of the high-voltage system in an ignition-on state, to receive the input signals and conditions, and to selectively prevent access to the AC-side via a corresponding control action using the received input signals and conditions. The input signals and conditions include the open/closed position of the hood, a PRNDL position, and a powertrain mode of the vehicle.
