[. . . ] Increasingly heavier traffic, the ever-decreasing availability of raw materials and our increasing sense of safety and environmental awareness mean that we are constantly facing new challenges. We seize on these tasks, seeing them as an opportunity to place trust in the knowledge of our many specialists in a lot of different fields of business, particularly in the commercial vehicles sector. As market and technology leader for tachographs, and with our control and monitoring systems for drive and on-board electronics, the on-board units for toll collection, the telematic units and display instruments, we are securing the economic and ecological progress of the commercial vehicle industry for today, tomorrow and the future. 2 General information Technical conditions Legal requirements Solutions Advantages 4 6 7 8 10 3 General information Excessive speed in driving heavy vehicles has been a social and governmental issue around the world for many years, primarily from the perspective of road safety. [. . . ] With increased engine power and long axle ratio, attainable speeds for trucks are currently much higher than the speed limits on highways and secondary roads in many countries. Excessive speed in trucks has numerous consequences, including: · igherratesofaccidentsinvolvingfatalities H and serious injuries ·ncreasedoperatingandmaintenance I costs for the transport industry ·Increasedcostsforinsurancecompanies ·Greaterenvironmentalpollution 4 One effective solution to prevent speeding in commercial vehicles is to equip them with a road speed limiter system, which restricts maximum road speed to the required speed limit without loss of engine power. This is realized by limiting the required fuel demand according to a set speed limit. The maximum speed limit is set using an electronic control unit. Information about the current speed of the vehicle is measured with a speed sensor that supplies an electronic speed signal to the control unit. The control unit limits the fuel output in different ways, depending on the fuel injection technology of the engine. In addition to its main function, limiting the maximum speed, the system offers a variable speed limiter as an option. This makes Pedal Interface II suitable for use on nearly all types of vehicles. It can be configured by authorized personnel to meet the needs of a wide range of applications.

Its construction corresponds to European regulations. In addition to the top speed limiter, which limits vehicle speed to a preprogrammed value, the unit includes a variable speed limiter for use at speeds between30KPHandthemaximumspeedlimit. By pressing the variable speed limiter switch, the driver can choose any speed within this range, and the controller limits the speed according to the driver's demand. Alternatively, the unit can be preprogrammed for a second speed limit below the maximum speed limit. The electronic control unit is self-diagnosable. [. . . ] The electronic control unit is self-diagnosable. The electrical actuator is a device that has been tested and proved over years of operation in everyday use. Various application sets are available.
