Methods and systems are provided for processing information associated with vehicles via one or more servers of a cloud system. One example method includes establishing a communication link between a computing device associated with a vehicle and a server. The communication link is over a wireless network and the communication link is established in association with a user account. The communication link is established for one or more sessions The method further includes receiving, at the server, a plurality of actions associated with inputs to the vehicle. The plurality of actions are received during the one or more sessions, and generating, by the server, a recommendation to program a setting at the vehicle. One or more of the plurality of actions at the vehicle during the one or more sessions are processed to determine a confidence score associated with generating the recommendation to program the setting. Generation of the recommendation occurs upon reaching or exceeding a predefined threshold. The server then sends to the user account the recommendation to enable programming of the setting for the vehicle.

A method for operating a recuperation brake of a motor vehicle is disclosed. First, a future operating intensity of the recuperation brake is estimated for a section of route to be travelled on by the motor vehicle based on an input which characterizes the driving style of the section of route to be travelled on. In addition, a maximum slip-free vehicle braking power for the section of route is estimated as a function of the input. In addition, the braking power of the recuperation brake is set to a setpoint braking power which is not greater than the maximum vehicle braking power for the section of route, and finally the recuperation brake is activated on the section of route to be travelled on with the setpoint braking power. In addition, a recuperation brake for carrying out the method is described.

The departure time scheduling control system includes an electric vehicle having an electric power storage device and an interior climate control device operable to vary an interior temperature. A user interface includes a display and an input portion which allows a user to schedule a departure time having a temperature setting and a charge mode setting having an immediate mode and a delayed mode. A charger unit controls the charging of the electric power storage device to the preset charge level accordingly to the charge mode setting by the departure time. A controller activates the interior climate control device to bring the interior temperature to the temperature setting by the departure time. The controller also activates the charger unit to charge the electric power storage device according to the charge mode setting to the preset charge level by said departure time.

A vehicle includes an electric machine configured to propel the vehicle using battery power. The vehicle also includes a controller programmed to operate the electric machine along a predetermined route based on a superposition of a plurality of partitionings of the route. Each of the partitionings is based on a different force characteristic associated with the route and defines at least one segment transition, where each segment transitions defines an end of a previous segment and a beginning of a subsequent segment. The predetermined route segments are such that no two adjacent segments of the superposition are defined by a same force characteristic.
