Australian technology startup, OzXCorp, has today announced the release of the world’s first hybrid drive technology for a recreational vehicle, allowing a caravan to push a car up a hill, regenerate over the course of a journey, and deliver a better driving experience across all types of terrain.

The burden of today’s recreation vehicles

The recreation market has seen significant adoption of technology endeavouring to add value, convenience, and simplify user experience.

One aspect of caravanning that remains a burden on every driver is the constant reminder that your caravan is affecting the performance of your vehicle, fuel consumption, manoeuvrability, traffic flow, and consequently the drivers mental and physical ability to remain alert.

Many adventurers opt to buy vehicles that are equipped with significant engine capacity and gross vehicle mass to mitigate the burden of towing and power loss, however, this improvement in driving experience comes at a significant cost in the purchase of vehicle, fuel and the environment.

Introducing DriveX: Hybrid drive technology for caravans

OzXCorp Co-Founder, Andrew Huett, has intimate knowledge of the above issues having logged some +70,000kms (+43,000 miles) around Australia’s diverse landscapes and has identified solutions that tangibly deliver a better driving experience across all genres of driving and terrain.

“Hybrid drive technology is not new but the adaption of these principles to caravans is a unique challenge by virtue of the caravan being an autonomous vehicle,” Huett said.

“We have been able to deliver a hybrid drive system that is affordable, practical, and transposes to your domestic requirements once you reach your destination.”

OzXcorp’s patented system delivers a holistic solution for all trailers, but specifically marine and caravanning sectors.

The power of hybrid drive

Day-to-day driving of your caravan is improved by offsetting the “dead-weight” of the caravan so that the presented load due to lateral acceleration is reduced, or in some cases, mitigated completely. “Start-stop traffic feels fluid and acceleration, or even overtaking, instills confidence and that reinstates enjoyment in the journey,” Huett said.

The regenerative aspect of the hybrid drive ensures energy that was normally lost in your mechanical brakes is recovered, resulting in notable fuel saving and consistency of speed.

Trailer parking

If there was ever a reason not to buy a caravan it is most likely due to the hardship of reverse parking your caravan into tight spots - common to holiday parks, residential addresses, or storage.

OzX address this with the use of torque control, putting you in control of the trailer from your mobile device at a maximum speed of 2kph (1.24mph) with the ability to crawl up and over gutters, up and down driveways, and back to your vehicle to re-hitch.

Overlanding and off-roading

Every keen adventurer will know that pulling a trailer through mud and sand is risky, and sometimes just embarrassing, once stuck. You typically have to apply significant speed to negotiate this type of terrain and in most respects that is due to the trailer acting as a “dead-weight” on your tow vehicle.

OzX uses bespoke settings like Sand and Mud Assist, driving the wheels in a combination of torque and speed control to actively drive the trailer through mud and help the trailer plane-up on sand, not dig in.

When enabled, Hill Assist will allow you to rock-crawl over extreme terrain typically experienced exiting a river crossing or traversing a rocky incline. Think of the trailer having either two or 4WD capabilities with traction control and electronic differential-lock. In combination with your 4WD vehicle, you have an unstoppable platform empowering the most adventurous of adventurers.

Impeccable Safety Capability

The hybrid drive system has added advantages of real-time stability control, torque vectoring, ABS and brake-blending. Systems that would normally be of significant cost, complexity and fragmented architecture are now harmonised and embedded in the DNA of hybrid drive.

Features such as torque vectoring would add a new level of controllability by braking one wheel but driving the other so that both the vehicle and the caravan have a responsibility to vector safely in a new direction

In some countries, break-away systems are compulsory and avert an uncontrolled trailer from spearing into oncoming traffic at speed. OzX’s hybrid system immediately recognises a breakaway situation and applies braking, indicating and undertaking a controlled deceleration process. In an advanced form under research development, and in alignment with SAE J3016 (level 3 / 4), autonomous control would allow a breakaway trailer to self-drive at speed, negotiate traffic conditions and make a plausible decision to exit a highway and park.

Advanced energy management

As Huett explains, “it is both impractical commercially and weight wise to make the trailer fully electric driven, that is, fitted with >80kW/hrs of battery. However, most of the benefits of an electric drive system can be realised by making a hybrid drive system that utilises a smarter energy management system.

“To that end, our customers plan their trip from point A to B and our systems maximise their return-on-investment by saving maximum fuel, maximising the driving experience or a blend of several attributes including re-charging from an EV charge point. Further, prior to arrival to destination, you will be fully recharged to ensure your camping experience is supported with a 5kW inverter married to a 16kW/hr battery pack.”

Huett goes further to advise “whilst set up at your destination, it is possible to recover 1500 to 2200kW of solar energy, as we have jointly coordinated rooftop design in light with maximum solar energy recovery. "Running your air conditioner, cooking on an induction cooktop, and even make use of the power to run a mobile coffee business, is all now possible on this gasless hybrid drive platform”.
