Motorcycles are becoming ever more powerful, with constant improvements to their engines, chassis, and brakes. Electronically controlled functions such as traction control and antilock braking help riders stay safely in control of these high-performance motorcycles when accelerating and braking hard, even in bends. The Bosch SU-MM5.10 lean-angle sensor supplies the vehicle dynamics data these functions need. It measures the motorcycle's longitudinal, lateral, and vertical acceleration, as well as yaw, pitch, and roll rate during the ride and uses this information to calculate its lean and tilt angle. Ducati is putting this powerful sensor equipment at the heart of its exclusive 1199 Superleggera. The data provided will be used for functions such as the new Ducati Wheelie Control. On top of these, Bosch is supplying its ABS 9M, a compact, high-performance ABS system.

The lean-angle sensor weighs just 40 grams, around 60 percent less than its predecessor, and is some two-thirds smaller. This very compact unit can be integrated flexibly into motorcycles. The use of micromechanical components built using MEMS (micro-electro-mechanical systems) technology reduces its power consumption to just 65 milliamperes. The SU-MM5.10 can be combined with any motorcycle ABS, not just a Bosch system. What is more, based on customer specifications, the lean and tilt angle can also be computed using an external control unit, with the lean-angle sensor providing what are known as 5D signals: the longitudinal, lateral, and vertical acceleration, as well as the motorcycle's yaw and roll rates. The lean-angle sensor communicates all the data it measures and calculates to the CAN bus.

Bosch supplies braking systems for all motorcycle classes
Bosch supplies brake control systems for all motorcycle classes based on the current Generation 9 ABS, ranging from a robust front ABS, which controls the front wheel exclusively, to base and plus versions, as well as ABS enhanced. This, the most advanced version, offers an electronic cross-domain function that creates the best possible distribution of brake force between the two wheels – even if the rider only applies one of the brakes. The end of 2013 will also see Bosch Motorcycle Stability Control going into series production, a safety system that adjusts engine and braking performance according to lean and tilt angle. Of course, the system cannot suspend the laws of physics – but it will keep the motorcycle extremely stable, even when braking hard in bends.

Mobility Solutions is the largest Bosch Group business sector. In 2015, its sales came to 41.7 billion euros, or 59 percent of total group sales. This makes the Bosch Group one of the leading automotive suppliers. The Mobility Solutions business sector combines the group’s expertise in three mobility domains – automation, electrification, and connectivity – and offers its customers integrated mobility solutions. Its main areas of activity are injection technology and powertrain peripherals for internal-combustion engines, diverse solutions for powertrain electrification, vehicle safety systems, driver-assistance and automated functions, technology for user-friendly infotainment as well as vehicle-to-vehicle and vehicle-to-infrastructure communication, repair-shop concepts, and technology and services for the automotive aftermarket. Bosch is synonymous with important automotive innovations, such as electronic engine management, the ESP anti-skid system, and common-rail diesel technology.

The Bosch Group is a leading global supplier of technology and services. It employs roughly 375,000 associates worldwide (as of December 31, 2015). The company generated sales of 70.6 billion euros in 2015.
