A method is provided for operating a motor vehicle which has at least one electric machine as a driving device. The method includes examining a current driving situation to determine whether a target position can be reached with a target speed by coasting; displaying a message to a driver of the motor vehicle if the target position can be reached by coasting; detecting a reaction time of the driver from the message up to the initiation of a coasting process by the driver; and actuating the electric machine as a generator to generate a deceleration torque if the reaction time exceeds a predefinable limiting value.

A waste heat utilization device for a motor vehicle includes a waste heat utilization circuit in which a working medium circulates. The water heat utilization circuit includes a conveying device, an evaporator, an expansion machine, and a condenser. The waste heat utilization device also includes an electrical generator in direct or indirect drive connection with a power take-off shaft of an internal combustion engine. The expansion machine is in direct drive connection with the power take-off shaft of the internal combustion engine for purposes of energy recirculation.
