The concept of a motorcycle-autopilot system is likely to be anathema to many, however the identical expertise that permits an rising variety of fashionable vehicles to steer, speed up, and brake routinely is clearly heading to 2 wheels sooner or later.
Most of us journey for pleasure, so a self-riding bike initially sounds as interesting as a steak that eats itself, to save lots of you the difficulty. Nevertheless it’s laborious to argue that hours of straight-line driving on a freeway can present as a lot pleasure as a couple of minutes on a twisting again highway. What’s extra, as fashionable automotive security methods show, tech that may present semi-autonomous driving may step in to stop or mitigate accidents. The truth that Honda—a pioneer of such methods on 4 wheels—is working to deliver them to motorcycling is a logical development.
Honda is likely to be lagging behind BMW, Ducati, KTM, and Kawasaki in the intervening time, in the case of becoming radar-assisted adaptive cruise management and warning methods to bikes, however that’s prone to be a results of the agency’s custom of growing expertise in-house slightly than adopting current, off-the-shelf expertise. Over the past couple of years, Honda has left a paper path of patent functions that illustrate simply how severely it’s taking semi-autonomous driving, and now one other such doc has been printed that reveals how a bunch of particular person methods could be built-in to work collectively in a seamless security system.
We’ve already seen patents displaying that Honda is growing radar methods, prone to seem on fashions just like the Gold Wing and Africa Twin initially. Whereas the corporate’s personal Driving Help and Driving Help-e ideas have revealed a working steering-control system, working in tandem with computerized braking and acceleration to permit bikes to steadiness themselves at low pace—even with out a rider on board.

Its newest patent reveals how these options could be mixed, together with different applied sciences together with: on-board cameras, a LiDAR (gentle detection and ranging) sensor, GPS, and short-range vehicle-to-vehicle communication methods to create a motorcycle that may intervene when required with an autopilot-like cruise management or support when the rider fails to identify or react to a hazard.
The patent, titled “Drive Help Gadget for a Saddle Driving Kind Automobile,” reveals a bike fitted with cameras, radar, and LiDAR that makes use of that array to construct a 3D picture of its speedy environment, monitoring different objects and automobiles and successfully conserving a watch out in each route to observe for risks. It describes a built-in steering servo, utilizing the identical “magnetostrictive” torque sensor expertise (that Yamaha is utilizing to check power-assisted steering on its 2022 works motocross bikes) that may distinguish between rider inputs and exterior forces—resisting actions of the wheel from bumps or potholes however serving to to show the wheel once you put stress on the bars. There are additionally stress sensors within the seat, handlebar grips and footpegs, permitting the bike’s laptop to inform when you’re holding on with each arms, mixed with a rider-facing digital camera fitted to the sprint, monitoring your posture and weight distribution to assist interpret your intentions.
It would sound excessive, however most of those methods are developments of concepts already utilized in high-end vehicles to allow semi-autonomous driving. Honda has loads of expertise right here, because it was among the many first to introduce radar-cruise management and lane-keeping methods on vehicles—going again to as early as 2004. Honda’s Japanese market Legend luxurious sedan is the primary out there on this planet with a Stage 3 Autonomous system, which might pilot itself in congested site visitors and in sure circumstances doesn’t even require the motive force to concentrate and be able to take management.
Honda’s motorbike model of the system, described within the new patent, contains adaptive cruise management and lane-keep help in addition to the power to keep away from obstacles within the highway, however in some methods it’s truly extra complicated than the tech used on vehicles. Particularly, it has to recognise the truth that bikes have way more flexibility in the case of how they use the lanes they’re driving in. The patent explains that, when cornering routinely, a motorcycle will use its sensors and GPS to straighten corners as a lot as doable, taking a large entry line, reducing towards the apex and drifting wider once more on the exit, all whereas staying in its lane. It additionally reveals that when following one other bike, the system will transfer to at least one facet of the lane to create a staggered sample and provides extra stopping distance.
Don’t anticipate to have the ability to purchase a motorcycle with this expertise anytime quickly. That is clearly a long-term mission, and we are able to anticipate it to evolve over generations of the expertise. A radar-assisted adaptive cruise management and lane-keep-assist system is prone to be step one—in all probability approaching a future-generation Gold Wing—however in a decade’s time it’s fairly doable that your bike will be capable of step in and prevent from an accident earlier than you’ve even realized the chance was there.
