A motion detection and interlock mechanism prevents unintended drive-off of a trailer still connected to a charging source, which could cause damage and/or injury if continued unimpeded. Trailer power for electrical components is a high voltage AC connection, typically between 277-480 VAC. Forced disconnection of an engaged plug could damage the plug and receptacle, leave electrical conductive members unprotected, and cause a short circuit. Electrical connections to trailers may be made for powering electric TRUs (Transport Refrigeration Units) for refrigerated loads, and for charging a storage battery for powering the TRU over the road or even the tractor itself in the case of a hybrid/electric tractor. In configurations herein, an e-axle is provided on the trailer suspension, such that a driveaway prevention circuit reverse biases the wheels to prevent movement of the trailer while engaged with a charging outlet.

A working machine management system includes a working machine having a prime mover and a control unit and a key device which is detachable from the working machine and is used for operating the working machine. The key device stores first authentication information for identifying a drivable working machine and second authentication information necessary for the prime mover to continuously operate. When the key device is attached to the working machine, the control unit confirms validity of the key device based on the first authentication information, compares input information from the outside with the second authentication information to determine whether the prime mover can be operated if the key device is valid, and controls operation of the prime mover according to the determination result.

A disclosed system includes a mobile application operative on a mobile device to receive user selected options for limiting drive access to a vehicle when the user is not physically present with the vehicle but wishes to allow service personnel access and limited drive functions. The disclosed system allows user selection of the options, then generates an instruction set for controlling one or more drive capabilities of the vehicle based at least in part on the user selected options. The system establishes an encrypted channel between the mobile device and a telematics control unit of the vehicle. The system controls drive capabilities of the vehicle via the encrypted channel such that the mobile application user can provide remote access for locking, unlocking, ignition, and further restrict drive functions based on time, date, distance, geo-fence options, and other criteria.
