Advanced rider assistance systems for two-wheeler

Riding in heavy traffic and maintaining the correct distance to the vehicle in front takes a great deal of concentration and is strenuous over longer periods. ACC adjusts the vehicle speed to the flow of traffic and maintains the necessary safe following distance. This can effectively prevent rear-end collisions caused by insufficient distance to the vehicle in front. And not only does ACC offer riders more convenience, it also allows them to concentrate more on the road, particularly in high-density traffic.

Not paying attention for a moment can have serious consequences in road traffic. To reduce the risk of a rear-end collision or mitigate its effects, Bosch has developed the forward collision warning system for motorcycles. It is active as soon as the vehicle is started and supports the driver in all relevant speed ranges. If the system detects a critical proximity to a vehicle in front and the driver fails to react to the dangerous situation, it warns the driver via an acoustic or visual signal.

This function keeps a lookout in all directions to help motorcyclists change lanes safely. A radar sensor serves as the blind spot detection’s eye, registering objects in hard-to-see areas. Whenever there is a vehicle in the rider’s blind spot, the technology warns them by way of an optical signal, for example in the rear-view mirror.

For two-wheelers, traffic jams can be strenuous as well as dangerous. Riders must constantly apply the clutch, use the brakes, and then start moving again. To make this task easier, Bosch launched adaptive cruise control back in 2020. Once the desired speed has been set, this system constantly matches the vehicle’s speed to the flow of traffic while maintaining the necessary safe distance from the vehicle in front. With adaptive cruise control stop and go function the technology has reached a new level. It can bring the motorcycle to a controlled standstill and can take of again when the rider pushes a button or engages slightly the throttle. In vehicles with an automatic transmission no operation of the clutch is required.

Group riding in a staggered formation is popular among motorcyclists, though it can be challenging with adaptive cruise control, because the function expects the motorcycles riding in front to be in the middle of the lane. This function is a useful addition to Adaptive cruise control – stop and go.

Using an algorithm, it detects when a group is riding in a staggered formation and regulates the speed to automatically maintain the same distance from the motorcycles in front. In this way, the function assists riders in achieving a natural group formation.

When traffic is flowing it helps maintain an appropriate distance from vehicles in front and thus prevent rear-end collisions. With Adaptive cruise control – stop and go., a desired speed must be set; but when riding distance assit is activated, the motorcycle can be controlled as normal via the throttle grip.

• While riding, the system automatically reduces the vehicle’s acceleration or applies the brakes as and when required.
• Riders can set the desired distance from the vehicle in front beforehand.
• Riders can use a switch to deactivate the function or apply the throttle to override the deceleration generated by the Riding distance assist system, which enables the function to blend naturally and comfortably into the dynamic flow.

Hazardous situations on the road require not only a rapid response but, in many cases, emergency braking. Every second counts when it comes to preventing collisions and avoiding potentially serious consequences. Emergency brake assist is triggered when the system detects a risk of collision, and the rider doesn’t brake hard enough. In this case, the function actively increases the wheel brake pressure further to reduce the bike’s speed as quickly as possible.

Even in a car, it can be hard to keep a constant eye on traffic approaching from behind; but on a motorcycle, it requires an extra level of concentration.

Rear distance warning monitors the situation behind the rider and flashes a warning on the display if another vehicle gets too close. Based on this warning, the rider can take mitigating action to prevent a rear-end collision.

Rear collision warning warns vehicles behind the motorcycle when a rear-end collision is imminent, for example by activating the hazard warning lights. In this way, the function protects motorcyclists from accidents caused by having to brake unexpectedly or by a vehicle failing to see them – whether waiting at traffic lights, sitting in a traffic jam, or riding in free-flowing traffic.
