Abstract

A method for remotely controlling a motor vehicle, wherein the motor vehicle comprises a steering system and a drive train, which can both be electronically actuated by control means of the motor vehicle and by way of which the motor vehicle can be driven automatically. The control means of the motor vehicle have a wireless communication link to the touchscreen device so that automatic driving of the motor vehicle can be remotely controlled by way of the touchscreen device.

Claims

1. A method for controlling the driving of a motor vehicle, the motor vehicle comprising a tractor unit and at least one trailer, the tractor unit comprising a steering system, a drive train, and an electronically-actuated controller configured to allow automatically driving the motor vehicle by remote control from a touchscreen device wirelessly linked to the electronically-actuated controller, the method comprising:

displaying on the touchscreen device a first graphical representation of the tractor unit and a second graphical representation of the at least one trailer, wherein one of the first graphical representation and second graphical representation is an active part configured for responding to user touch inputs and another of the first graphical representation and second graphical representation is a passive part unresponsive to user touch inputs, wherein during remote control of driving in a forward direction the first graphical representation is said active part, and wherein during remote control of driving in a reverse direction the second graphical representation is said active part; and

responding to said user touch input to said active part of the touchscreen device which the active part is moved on the touchscreen display relative to the passive part by communicating commands from the touchscreen device to the electronically-actuated controller over a wireless link for remotely controlling driving of the motor vehicle.

2. The method according to claim 1, wherein said communicating commands comprises communicating commands to continuously regulate at least one articulation angle between a longitudinal axis of the tractor unit and a longitudinal axis of at least one of said at least one trailer.

3. A method according to claim 2, wherein a lateral position (y) of a displaced active part divided by a maximal lateral position y_max of the displaced active part equals a target articulation angle φ

_TARGET divided by a maximal articulation angle.
