<<reversemytrailer for mobile devices is a modified version of the driving simulator program originally created for Windows desktop. All of the main features of the simulator are available in the mobile version, with user controls adapted for operation on the touch-sensitive screens of mobile devices.
Forward and reverse speed is controlled by swiping a finger up and down either of two panels located on the left and right-hand side of the screen. These panels are transparent when not in use but will become visible (coloured red) when your finger is correctly positioned on the screen.
Tap the PAUSE button on the left-hand panel button at any time to stop the vehicles. Tapping the RESET button will reset them to their starting positions.
Steering is controlled by either swiping a finger horizontally left and right anywhere on the screen, or by tilting your device left and right. Select the steering method you prefer by tapping the STEER button on the left-hand panel, or via the Simulator Settings option of the main menu.
Current settings for speed and steering are shown on coloured indicators located at the edges of the screen. The steering indicator runs along the top of the screen, with the speed indicator running down the right.
A small, inset image showing steering wheel rotation is also displayed as a further guide while the vehicles are moving.
The indicator markers are colour coded as follows:
| Direction | Colour |
| Left | Green |
| Right | Red |
| Forward | Blue |
| Reverse | Purple |
There are three driving modes to choose from - autopilot, guidance and normal - which can be selected by tapping the DRIVE button, or via the Simulator Settings option of the main menu.
In autopilot mode, steering is controlled by the simulator. Simply set the vehicles moving in reverse and the simulator will demonstrate how to complete the manoeuvre.
A second visual indicator located above the steering indicator shows how much right or left steering is being applied.
In guidance mode, the suggested steering position is shown on the upper indicator and it's up to you to try to match it using the steering control.
In normal mode you need to use your own judgement, although there are guide rails displayed on the ground which show the suggested approach route.
You can also make use of the Trailer Direction Indicators feature, which is selected via a button on the main screen.
These are coloured lines displayed on either side of the trailer that show the predicted direction of travel of the trailer for any given steering position.
Simply adjust your steering so that the indicators point in the direction you wish to go.
Six different simulator views are available. These are selected via the three buttons below the main menu, labelled VIEW, MIRROR and AUTO.
The VIEW button is used to switch between views external to the vehicles (observer, trailer and bird's-eye views).
The MIRROR button switches between right and left driving mirror views.
The AUTO button automatically selects right or left driving mirror views when reversing, and a front window view when driving forwards.
The bird's-eye view gives a simple view from above which clearly shows the wheel positions and angles of both vehicles.
The observer view is useful when looking at autopilot demonstrations.
The reversing mirror views give a more realistic driver's-eye view of the manoeuvre.
You can switch between left and right mirrors by tapping the MIRROR key at any time while you are manoeuvring.
Pressing the AUTO button enables the auto mirror view feature. The simulator will then automatically try to select the most useful mirror view at any given point in the manoeuvre. This is usually the one where the trailer is most clearly visible in the mirror. However, this can easily change from one mirror to the other during the manoeuvre - especially if it involves an S-shaped turn.
The simulator will also automatically switch briefly to the other mirror view every few seconds. This is intended to emulate the real-world actions of a driver who focuses attention on one mirror but occasionally glances at the other.
Of course, if you prefer you can still switch manually between left an right mirrors at any time.
When going forwards, a forward-looking front window view is automatically displayed. This is to allow 'shunting' forwards and backwards while manoeuvring.
The trailer view is selected using the VIEW button. It shows the scene from a view point fixed above and behind the trailer, looking forwards.
You may find this view helpful if you are used to playing computer driving games.
All vehicle and scene models are stored in an online library. Whenever a model is added or updated, the latest version is automatically downloaded to your device next time the app starts.
Different combinations of towing vehicles and trailers can be selected via the Simulator Settings option of the main menu. Scenes and manoeuvres are selected in the same way.
A list of the currently selected options is displayed when Simulator Settings is selected.
Here is a summary of which gestures are recognised and what they do:
| Gesture | Description |
| Swipe left / Tilt left | Steer left |
| Swipe right / Tilt right | Steer right |
| Swipe up | Forward speed |
| Swipe down | Reverse speed |
| Tap | Stop |
And here is a summary of what the buttons do:
| Button | Description |
| V | Switch between Observer, Trailer and Bird's-eye views |
| M | Switch between Left and Right Reversing Mirror views |
| A | Switch automatically between Left and Right Reversing Mirror views |
| D | Switch between Autopilot, Guidance and Normal driving modes |
| S | Switch between Screen Swipe and Tilt steering modes |
| R | Reset |
In this mode, left/right steering and forward speed controls are disabled - only reverse speed may be selected.
Returning the vehicles to the start of the manoeuvre can be done at any time using the PAUSE/RESET button However, if you want to drive the vehicles forward to a different starting position you must first select normal (or guidance) mode.
Suggested steering positions shown in the visual indicator may fluctuate slightly, due to the fact they are being calculated in real-time, so don't be tempted to try to match them too precisely!
Select a low reverse speed when manoeuvring. It's much easier to spot when steering changes are required and to make them before things begin to go wrong.
Although no steering instructions are given here, guide rails drawn on the ground can be followed to help achieve a suitable approach route. Try to keep the trailer wheels within these rails as you complete the manoeuvre.
If you want more of a challenge, try selecting difficulty level 2 which will hide the guide rails. This will also change the operation of the RESET button (see below).
These are probably the easiest (and most realistic) views to use.
You can quickly switch between left and right reversing mirrors while manoeuvring to check both sides of the trailer by tapping the MIRROR key.
Alternatively, select the auto mirror feature and the simulator will try to show you the most appropriate mirror view at any given point in the manoeuvre.
To maintain a stable turn, try to use small steering adjustments to ensure the trailer does not move left or right too much in the mirror views.
drivWhen the RESET button is tapped, the vehicles are moved to a pre-determined position in the scene. This position depends upon the difficulty level setting as follows:
Level 1: At the start of the currently selected approach route.
Reversing can begin immediately. If you have selected one of the mirror views, the most appropriate initial view will be selected for you when you tap the RESET button. To avoid confusion, a clear visual indication is given showing which mirror view has been selected.
Level 2: A location away from the start of the selected route.
From here you must first align the vehicles yourself before beginning the reversing manoeuvre. It may be easier to select the Bird's-eye view to see your location more clearly when driving to a particular starting position.
An amber warning bar will appear at the bottom of the screen if you reach a point in the manouevre where a jack-knife condition is approaching. At this point, the jack-knife will be impossible to avoid if you continue to reverse, regardless of steering adjustments.
To recover, you must must first drive forwards to straighten the coupling before resuming the reversing manoeuvre.
A red warning bar indicates that the jack-knife condition has been reached.
