    摘要: A longitudinal driver assistance system, in a hybrid vehicle equipped with at least one electric drive motor, one internal combustion engine and one electronic drive control unit which actuates said motor and engine, includes: a detection system for the predictive detection of an event which, starting from an actual speed, leads to the specification of an increased setpoint speed at a specified location-dependent time, and a function unit which is configured to specify a setpoint acceleration profile to the increased setpoint speed and to output it to the drive control unit for generating a motor/engine torque which is necessary to reach the setpoint acceleration profile. The function unit is also configured to receive, when a defined condition applies, a limiting maximum possible motor/engine torque from the drive control unit, which motor/engine torque is not sufficient to reach the setpoint acceleration profile, and to specify a changed setpoint acceleration profile on the basis thereof.

    摘要: A method for supporting energy-efficient deceleration of a vehicle includes determining a reference deceleration depending on a current speed or a speed profile of the vehicle, determining a starting time point and a starting speed of a deceleration of the vehicle, and determining a real energy consumption and a real distance between the starting time point and a current time point and/or ending time point of the deceleration. The method also includes calculating a reference time and a reference distance for a deceleration with the determined reference deceleration between the determined starting speed and the current speed and/or the speed at the ending time point of the vehicle, calculating an energy consumption for a differential distance from the determined real distance and the calculated reference distance, and calculating a real total energy consumption as the sum of the determined real energy consumption of the deceleration and the calculated energy consumption for the differential distance. Further, the method includes calculating a reference energy consumption for the reference deceleration from the starting speed to the current and/or ending speed depending on a predefined deceleration type of the reference deceleration and/or depending on the determined real energy consumption of the deceleration, and then providing an energy-saving potential on the basis of a difference between the real total energy consumption and the calculated reference energy consumption.
