Abstract
A device is provided for operating an internal-combustion engine of a motor vehicle having a power actuator and a control unit. The control unit is configured for adjusting the power actuator as a function of a load demand on the basis of a displacement of the driving pedal by the driver, wherein, during an efficiency mode demanded and activated by the driver, independently of the displacement of the driving pedal, a rotational-speed-dependent consumption-optimal first load demand, and as a function of the displacement of the driving pedal, a second load demand, are determined. The control unit is configured for adjusting the power actuator while taking into account the determined first and second load demands.
Claims10
A device for operating an internal-combustion engine of a motor vehicle having a power actuator, the device comprising:
- a control unit that adjusts the power actuator as a function of a load demand based on a displacement of a driving pedal by a driver of the motor vehicle, wherein
- during an efficiency mode of operation demanded and activated by the driver, the control unit determines:
- (a) a rotational-speed-dependent consumption-optimal first load demand independently of a displacement of the driving pedal, and
- (b) a second load demand as a function of the displacement of the driving pedal;
- and
- Wherein the control unit adjusts the power actuator by factoring into account the determined first and second load demands.
A method of operating an internal-combustion engine of a motor vehicle having a power actuator, the method comprising the acts of:
- adjusting, via an engine control unit, the power actuator as a function of a load demand based on a displacement of a driving pedal by a driver of the motor vehicle, wherein
- during an efficiency mode demanded and activated by the driver, the control unit determines (i) a rotational-speed-dependent consumption-optimal first load demand independently of a displacement of the driving pedal, and (ii) a second load demand as a function of the displacement of the driving pedal;
- and
- adjusts the power actuator while factoring into account the determined first and second load demands.
