Sensors and software algorithms evaluate yaw, roll and acceleration rates
The sensor box developed by Continental, which measures five centimeters by ten, is breaking new technological ground in several respects. It contains all the inertial sensors needed to measure the dynamic driving data. The box also contains the algorithm for evaluating the signals, computing the motorcycle’s tilt, and supplying this information quickly and in high quality to the vehicle’s other systems – which means that no further control unit is needed. The basic data measured by the sensors comprises the yaw around the vehicle’s vertical axis, the roll around its longitudinal axis, and its lateral acceleration.
As with the electronic traction control system (TCS) used for automobiles, this data enables a system to be introduced for motorcycles that significantly improves directional stability and road holding for two-wheel vehicles. The control electronics of the motorcycle traction control system intervene if there is a danger of the vehicle getting out of control as a result of its excessive speed, extreme tilt or too much slip. The engine management system and/or the brakes are used to adjust power output so as to stabilize the vehicle.
The signals from the sensor box also activate additional functions such as active curve lighting and automatic engine cut-off. Furthermore, the recording of driving data will enable the vehicle’s handling to be analyzed. Connectivity with GPS data and Google Maps will be available in future. Using the sensor box can also enhance performance in motorcycle racing.
Electronic systems will enable the number of accidents to be reduced
Europe’s motorcycle manufacturers have given voluntary undertakings to increasingly advertise two-wheel vehicles with more comprehensive safety and braking systems and to offer these as optional features. In addition to anti-lock braking systems (ABS) and traction control system (TCS), these include chassis systems and passive safety systems such as airbags. This commitment was given as part of the European Road Safety Charter, which aims to significantly reduce the number of accidents. Continental’s sensor box is a key component of these safety systems.
