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 the wheel speed of the wheels of drivable axles of a dual-track vehicle having at least two drivable axles, and to a corresponding vehicle, wherein the vehicle has a second axle for driving a first axle. A drive motor, a second drive motor for driving the second shaft, a device for detecting driving state parameters and a control device. The method comprises the steps of: determining the actual rotational speed of the first shaft, determining the rated rotational speed of the second shaft according to the actual rotational speed of the first shaft, and controlling the second drive motor such that at the second The determined rated speed is formed on the shaft. In order to determine the setpoint speed, a synchronous setpoint speed is determined on the basis of the actual speed of the first shaft, in which at least one wheel of the second shaft develops the same wheel peripheral speed as at the wheels of the first shaft. Next, the rated rotational speed of the second shaft is determined based on the determined synchronous rated 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,...
