Embodiment Construction

[0119] exist figure 1 The dual-track vehicle 100 according to the invention shown in the schematic diagram is a tractor vehicle designed as a hybrid vehicle for carrying out the method according to the invention, which has a first axle 110 forming the rear axle and a first axle 110 forming the front axle. The second axle 120, wherein the rear axle 110 and the front axle 120 have left wheels 111 respectively l or 121 l and the right wheel 111 r or 121 r .

[0120] To drive the tractor 100 , a first drive motor 130 and a second drive motor 140 are provided, wherein the first drive motor 130 is an internal combustion engine and the second drive motor 140 is a pole operable as an electric motor. Internal combustion engine 130 is provided here for driving rear axle 110 , while electric motor 140 is provided for driving front axle 120 . The rear axle 110 and the front axle 120 can be driven mechanically independently of each other, that is, the drive train of the rear axle 110 ...

Abstract

The invention relates to a method for controlling a wheel rotational speed of a wheel of a drivable axle of a two-track vehicle having two drivable axles and a corresponding vehicle, wherein the vehicle has a first drive motor for driving the first axle, a second drive motor for driving the second axle, a device for sensing driving state variables, and a control device. The method comprises the following steps: determining an actual rotational speed of the first axle, determining a target rotational speed for the second axle in dependence on the actual rotational speed of the first axle, and controlling the second drive motor in such a way that the determined target rotational speed is set at the second axle. In order to determine the target rotational speed, a synchronous target rotational speed at which the same wheel circumferential velocity is set at at least one wheel of the second axle as at the wheels of the first axle is determined in dependence on the actual rotational speed of the first axle. The target rotational speed for the second axle is then determined in dependence on the determined synchronous target rotational speed.

Description

technical field [0001] The invention relates to a method for controlling the wheel speed of at least one wheel of a drivable axle of a dual-track vehicle having at least two drivable axles, in particular to a method for controlling the speed of a wheel having at least two drivable axles Method of wheel speed of at least one wheel of a drivable axle of a vehicle configured as a tractor or a self-propelled work machine. Furthermore, the invention relates to a corresponding two-axle vehicle having two drivable axles. Background technique [0002] Methods for controlling the wheel speed of at least one wheel of a drivable axle of a dual-track vehicle having two drivable axles, such as passenger cars with all-wheel drive, are basically known in the prior art. [0003] In most of these methods, the wheel speed of at least one wheel is controlled in a traction-optimized manner, i.e. the aim is to achieve the greatest possible traction with the respective wheel or with the vehicle,...
