A power generation system adopted for use on a vehicle comprises a first rotary member, a second rotary member, a transmission gear set and a brake module. The first rotary member includes a first gear, and a housing space for installation of the second rotary member. The second rotary member includes a second gear with a gear ratio smaller than that of the first gear, an excitation winding and an electric input portion. The transmission gear set includes at least one transmission gear which is driven by the first gear to drive the second gear to rotate in a direction opposite to the first gear. The brake module detects operation condition of a brake pedal and a drive pedal made by the driver, and outputs an excitation current to the electric output portion via a first brush to generate electric power.

The invention relates to a method for operating a motor vehicle comprising at least one electric machine as a driving device, said method involving the following steps: —verifying whether a current driving situation will allow the motor vehicle to reach a target position at a target speed by letting the motor vehicle coast; —displaying information to the driver of the motor vehicle if the target position can be reached by letting the motor vehicle coast; —measuring the time it takes the driver to react from the moment that the information is displayed to the moment that the driver initiates a coasting process; —actuating the electric machine as a generator in order to generate a deceleration moment if the reaction time exceeds a predefined maximum value.

The invention relates to a vehicle electrical system that includes a first energy accumulator which has a first maximum open circuit voltage when the first energy accumulator is fully charged, and a second energy accumulator which has a second maximum open-circuit voltage when the second energy accumulator is fully charged. The second maximum open circuit voltage is higher than the first maximum open circuit voltage. The vehicle electrical system also includes a generator configured to generate electrical energy for the vehicle electrical system and a control unit that is configured to detect a recuperation mode of the vehicle. The control unit is also configured to cause the generator, while the vehicle is in the recuperation mode, to generate electrical energy with a charge voltage which is in or above a buffer voltage range, wherein the buffer voltage range lies between the first maximum open circuit voltage and the second maximum open circuit voltage.
