A control device includes a changing rate calculator, a first threshold calculator, and a separation determiner. The control device determines whether a current collector is separate from a power line, in a power conversion system in which a power converter converts power supplied from the current collector to the primary side of the power converter into alternating-current (AC) power and supplies the AC power to a motor connected to the secondary side of the power converter. The changing rate calculator calculates a changing rate of the voltage at the primary side of the power converter. The first threshold calculator calculates a first threshold having the absolute value positively correlated with an output power from the power converter. The separation determiner compares the changing rate with the first threshold and determines whether the current collector is separate from the power line.

The present disclosure relates generally to a vehicle safety system. The vehicle safety system may include operational sensors sensing operational characteristics of a vehicle, environmental sensors sensing environmental characteristics of an environment external to the vehicle, and one or more processors. The operational and environmental sensors may output operational and environmental data based on the operational and environmental characteristics that are sensed by the respective sensors. The processors may examine the operational and environmental data to determine whether the vehicle is in a safe state for an onboard operator of the vehicle to exit the vehicle while avoiding the vehicle rolling away from a stationary state. The processors may examine the operational and environmental data to determine whether the vehicle is not in the safe state and may generate one or more notifications to the operator in response to determining that the vehicle is not in the safe state.
