METHOD FOR DETERMINING THE REMAINING RANGE OF A MOTOR VEHICLE

摘要

Method for determining the remaining range (39) of a motor vehicle (1) which has an energy store (5) for a drive which acts on at least one wheel of the motor vehicle (1) and has an electric motor (2), as a function of residual energy (34) in the energy store (5), wherein consumption values (17, 18, 19) which describe the current consumption of the drive and of at least one secondary consumer are determined using at least one sensor, a drive prediction value (20a, 20b, 20c) which is assigned to the drive and describes the consumption over a predetermined distance is determined from the consumption values (17) of the drive, and at least one secondary consumption prediction value (21, 22) which is assigned to the secondary consumers and describes the consumption over a predetermined distance is determined separately from the consumption values (18, 19) of the secondary consumers, and the remaining range (39) is determined for at least one distance which is to be travelled by the motor vehicle (1) and is described by the route data, by taking into account the drive prediction value (20a, 20b, 20c) and the secondary consumption prediction value (21, 22).
