Patent ID: 7501791

Claim:
A motor vehicle system for coordinating at least one vehicle function that is activatable and deactivatable, the motor vehicle system comprising: a drive unit; an electric energy accumulator unit; and at least one battery charge condition threshold value of the energy accumulator unit being assigned to the at least one vehicle function of the motor vehicle, such that on exceeding or falling below a given battery charge condition threshold value, the assigned vehicle function becomes activatable; and wherein different battery charge condition threshold values are assignable to the at least one vehicle function as a function of at least one of an operating condition of the drive unit, a temperature of the energy accumulator unit, a temperature outside of the vehicle, and an age condition of the energy accumulator unit, wherein the at least one vehicle function includes an automatic engine stop-start function, wherein at least three battery charge condition threshold values are assigned to the automatic engine stop-start function, such that: in an event of a start of the operation of the motor vehicle and in an event that, during an operating cycle a falling below of the lowest battery charge condition threshold value occurs, the vehicle function can be activated only when a battery charge condition above the top battery charge condition threshold value is present; and in an event that the top battery charge condition threshold value was exceeded once within an operating cycle and subsequently there was a falling below the top battery charge condition threshold value and there was no falling below the lowest battery charge condition threshold value, the vehicle function can already be activated when the battery charge condition is greater than or equal to the medium battery charge condition threshold value.
