Abstract: Disclosed is a road condition prediction system for vehicles. First, a computing device receives ambient temperature and relative humidity data from a vehicle, the ambient temperature and relative humidity data having been collected by a tire sensor mounted to an exterior of a tire of the vehicle or an exterior of a wheel of the vehicle. Then, the computing device applies a machine-learning model to the temperature and humidity data from the vehicle to predict a road condition for the vehicle. Subsequently, the computing device sends the road condition for the vehicle to a control system of the vehicle.

Abstract: A road condition monitoring system for a vehicle is provided. The vehicle is supported by at least one tire and includes a central communication system. The system includes a processor in electronic communication with the central communication system. An identifier is in electronic communication with the processor, receives vehicle condition data from the central communication system, and identifies a free rolling instance of the at least one tire. A slip estimator is in electronic communication with the processor, receives speed data from the central communication system, and determines slip characteristics of the at least one tire during the free rolling instance. A classifier is in electronic communication with the processor, receives the slip characteristics of the at least one tire, and identifies a road surface condition from the slip characteristics.

Abstract: A charging station for charging an electric energy storage means of an electric vehicle using alternating charging current, having a fault-current protective device and having a charging controller. The fault-current protective device is divided into its functional units, a differential-current monitoring unit forming an integral structural unit in the form of a charging-current controller and monitoring device in conjunction with the charging controller according to the invention. Alternatively, the fault-current protective device forms an integral structural unit in the form of a charging-current controller and protective device in conjunction with charging controller.

Abstract: The invention relates to a charging station for charging an electric energy storage means of an electric vehicle using alternating charging current, having a fault-current protective device and having a charging controller. In a first embodiment, the fundamental idea is based on carrying out the fault-current protective device modularly. For this purpose, the modular fault-current protective device is divided into its functional units, a differential-current monitoring unit forming an integral structural unit in the form of a charging-current controller and monitoring device in conjunction with the charging controller according to the invention. In an alternative embodiment, the fault-current protective device forms an integral structural unit in the form of a charging-current controller and protective device in conjunction with charging controller.
