A reverse current protection system for a vehicle electrical system that communicates with a trailer electrical system generally includes a mode determination module that receives a reverse current flow detection signal and that selectively determines a field effect transistor (FET) operating mode to be a reverse on mode based on the reverse current flow detection signal. A current flow control module generates a current flow control signal to a field effect transistor to control the field effect transistor based on the determined FET operating mode.

Reverse current protection methods and systems for trailer tow

A method of controlling a surge brake mechanism and all lights on a trailer connected to a vehicle that can submerse the trailer to deploy a boat into water. The method generally includes monitoring the vehicle for vehicle conditions that include at least a speed of the vehicle and a direction in which the vehicle is moving. The method waits for user input from within a passenger compartment of the vehicle that is indicative of a desire to disable all of the lights and the surge brake mechanism on the trailer. The method determines a boat launch condition exists when at least one enabling input is detected and determines the boat launch condition does not exist when any disabling input is detected. The method disables the surge brake mechanism and all of the lights on the trailer, when the boat launch condition exists and enables the surge brake mechanism and all of the lights on the trailer, when the boat launch condition does not exist.

Boat trailer submersion

The invention is the use of a software object as an interface between a device and a network. Both the network and device are located in a vehicle. The system uses a connectivity subsystem that includes a device management object for interfacing between a device and a network in the vehicle. A discovery subsystem identifies which devices are connected to the network by the connectivity subsystem. The control subsystem can then use the device management object to manage the use of the device. In the application layer of the system resides the software applications to be used by the devices and occupants in the vehicle. In the object interface layer of the system resides the software object that connects the network with the various software applications. The network resides in the network layer.
