Vehicle and operating procedures

Abstract

The invention relates to an operating method for a vehicle (1) with a battery (2), at least two electric drives (3.1, 3.2) powered by the battery (2), at least one of which is connected to an axle (9.1, 9.2) of the vehicle (1) via an axle disconnect coupling (8.1, 8.2), a passenger compartment (4), and a cooling circuit (5) for temperature control of the electric drives (3.1, 3.2), the battery (2), and the passenger compartment (4). An online optimization method is used at runtime in the vehicle (1) to select one or more of the following methods for maximum power loss operation to heat the battery (2) and / or the passenger compartment (4) via the cooling circuit (5): - Opening one of the axle disconnect couplings (8.1, 8.2) and setting an operating mode in which at least one of the electric drives (3.1, 3.2) is operated in such a way that the power loss for heat generation is increased. will,- shifting a gearbox (10.1, 10.2), which is arranged between at least one of the electric drives (3.1, 3.2) and the associated axle (9.1, 9.2), into a gear with a higher power loss, and- distributing a requested torque over the electric drives (3.1, 3.2) such that the power loss is maximized.
