ABS from Bosch not only makes braking safer, but also enhances performance. Value-added functions increase the level of safety, comfort and dynamics.
A helping hand for the operator — even when accelerating
Bosch ABS does more than just brake your motorcycle effectively. Combined with the traction control system, it also ensures that the rear wheel does not spin during vigorous acceleration and prevents the front wheel from leaving the ground.
The traction control can be integrated into all Bosch ABS generation 9 two-channel systems, and can be used both on and off road.
Thanks to the addition of a Bosch lean-angle sensor, the system is able to support the driver even when negotiating bends by measuring the dynamic status of the motorcycle 100 times a second and calculating the lean angle, pitch angle and vertical acceleration. The traction control then uses this data to provide maximum drive power on bends. This function can also be adapted for motocross vehicles.
The lean-angle dependent drag torque control is an additional function of motorcycle stability control (MSC). It counteracts critical situations that arise when drive torque suddenly increases or drops. In such cases, the driven wheel can lose traction and start to skid. This can happen when engine brake torque is too high – when changing to a lower gear too soon, for example – or when the rider suddenly lets go of the throttle on a slippery road surface. MSC detects the lean angle and the risk of traction loss, and instantly computes the best possible values for acceleration and braking.
Keep the fun of riding – even off the beaten track
Until now, the fun of riding with ABS ended when venturing off the beaten track — conventional antilock braking systems were not able to cope with the tougher conditions in the open countryside. Off-road maneuvers on sand or gravel surfaces were unachievable.
For this reason, Bosch developed a special off-road control, which can be integrated into the generation 9 ABS plus and ABS enhanced antilock braking systems to provide maximum safety on off-road terrain without affecting the offroad riding style.
In order to achieve optimum braking performance when riding off-road, the ABS control range starts a little later than it would on tarmac. This delay allows the rear wheel to dig into the ground and improve braking performance on off-road terrain. The front wheel control allows a higher level of deceleration without impacting stability.
Motorcycle manufacturers can adjust the off-road control to allow the rider to deactivate the system for controlled drifting maneuvers or for pulling the rear wheel around on hairpin bends.
Makes the fun of the ride reach new heights, not the rear wheel
When the brakes are strongly applied on two wheels, it is actually only one wheel that decelerates. This is because, on motorcycles, especially on a sporty one, the wheel load shifts in the direction of the front wheel, often causing the rear to lift up. To help in cases such as this, Bosch developed rear-wheel lift-up control.
This function evaluates the slip values of both wheels. If the rear wheel threatens to lift up while braking, the rear-wheel lift-up control adjusts the pressure in the braking circuit of the front wheel with precision to keep the rear wheel on the ground and avoid rollovers. This technology allows riders to remain more relaxed, whatever awaits them on their trip — be it wet leaves or bumps.
Making going uphill a breeze
Starting-up from standstill on a steep incline is no easy task, even for passenger vehicles. For a heavy-duty motorcycle, the task is even more challenging. The optional hill hold control function prevents motorcycles from rolling backwards unintentionally while riding uphill.
The sensors on the motorcycle, such as the longitudinal acceleration sensor, detect that it is on an incline and is stationary. Once the rider has released the brake lever and pedal, the function automatically holds the brakes for a second longer. This allows the rider to tackle any incline, without unintentionally rolling backwards, regardless of whether they are a beginner or an experienced operator.
