Connected vehicles are increasingly seen as a target for cybersecurity attacks. A key differentiator for the automotive industry is the use of cyber-physical systems, where a successful cybersecurity attack can affect physical entities. Often involving embedded electronics and real time control, these systems require different solutions in addition to established IT security principles and reactive responses to threats. Cybersecurity needs to be designed and built into cyber-physical systems throughout the development lifecycle to provide defense in depth.

On two wheelers magneto generate either single or 3 phase AC power and regulator rectifier unit(RRU) do regulated rectification to charge the battery. In order to face the requirements of 2-wheeler engine with respect to upcoming stringent regulations like EFI, ABS, AHO in emerging markets like India; vehicles are demanding more electrical power from batteries. This demands higher power from magneto hence regulator rectifier unit(RRU). Higher output power forces challenges on regulator rectifier unit in terms of size, power dissipation management and reliability. In this paper how performance of RRU improved with MOSFET based regulator rectifier are discussed in comparison to silicon controller rectifier (SCR) design. The motivation of MOSFET design is described as well as the thermal behaviour and temperature coefficient performance of RRU with test result.

In order to fulfill future regulations regarding emissions and CO2 reduction, the small engine market inclines to migrate from carburetor systems to cleaner, more efficient electronic ignition controls and electronic fuel injection systems. When implementing such mechatronic systems in small engine applications, one has to consider specific boundary conditions like the lack of relevant sensors, limited possibilities in terms of space and of course the necessity to keep the costs as low as possible. Especially in the non-road mobile machinery (NRMM) segment, the absence of sensors makes it difficult to apply standard electronic control systems, which are based on engine related input signals provided by sensors. One engine related signal, which even the simplest engine setup provides, is some form of the crankshaft speed since it is essentially for the functionality of the engine.

Accurate measurement of air volume is one of the large problems in LPL-EGR system. Measurement of air is difficult, because the intake volume of LPL-EGR system from the EGR valve to combustion chamber is much larger than HPL-EGR. Equally, it is difficulties to measure the correct LPL-EGR rate. By a conventional method, the best ignition timing control is difficult. The measurement of the LPL-EGR rate by using intake O2 sensor has been developed. Around 0% of LPL-EGR rate, this technique is poor accuracy.There is not a use except the LPL-EGR rate measurement. We thought that it was preferable for application of the engine control to use a wide sensor. About the ignition timing control, MFB 50% feedback control is to enable optimum ignition timing control by using the cylinder pressure. We thought about engine control by using the cylinder pressure, and we examined the following application.

Engine management systems combined with fuel injectors allow a precise fuel metering for a robust combustion process. Stricter emission legislations increase the requirements for these port fuel injection systems (PFI), whereas the price is still the main driver in the emerging low cost 2-wheeler market. Therefore, a holistic mechatronic approach is developed by Bosch, which allows an improved fuel metering over life time and furthermore provides new possibilities for diagnosis without changing the injector itself. This example of an intelligent software solution provides the possibility to further improve the accuracy of the opening duration of an injector. By use of the information contained in the actuation voltage and current, the opening and closing times of the injector are derivable.

For the development of a very high efficiency engine, the continuous monitoring of the engine operating conditions is needed. Moreover, early detection of engine faults is fundamental in order to take appropriate corrective actions and avoid malfunctioning and failures. The in-cylinder pressure is the most direct parameter associated to the engine thermodynamic cycle. Unfortunately, the cost and the intrusiveness of the sensor and the harsh operating condition that limits its life-time, make it not suitable for mass production applications. Consequently, research is oriented on the measurement of physical phenomena linked to the thermodynamic cycle to obtain useful information for the ICE control. For turbocharger engine application, the direct connection between the thermo-dynamic and fluid-dynamic conditions at the engine cylinder exit and the turbocharger behavior suggests that its instantaneous speed could give useful information about the engine cycle.

Alternative engine speed sensing using the electric signals of the alternator In the low-cost segment for 2-Wheelers legislative, economic and ecological considerations necessitate a reduction of the emissions and further improvement in fuel consumption. To reach these targets the commonly used carburetors are being replaced by Engine Management Systems (EMS). One option to provide these systems for acceptable and attractive system costs is to save a sensor device and substitute its measure by an estimation value. In many motorcycles the rotor of the vehicle's alternator is rigidly attached to the crankshaft. Therefore, the voltage and current signals of the alternator contain information about the engine's speed, which can be retrieved by evaluating these electric signals. After further processing of this information inside the ECU the absolute crankshaft position can be obtained.

Blind Spot Detection system for two-wheelers Bosch’s side view assist is the world’s first rider assistance system for two-wheelers. This is a Blind Spot Detection system which uses four ultrasonic sensors to monitor the surrounding of the rider. Whenever there is a vehicle (car, truck or another motorbike) in the rider’s blind spot, the technology warns by an optical signal close to the mirror, so that the rider can for example avoid a collision when changing lanes. Side view assist is active at speeds ranging from 25 to 80 kilometers per hour and supports riders whenever the difference in relative speed to other road users is small. The system helps improve safety especially in cities, where heavy traffic makes it necessary to change lanes more often. Originally such systems have been developed for passenger cars. Different system solutions for passenger cars are already in serial production since several years.

Data-driven plant models are well established in engine base calibration to cope with the ever increasing complexity of today’s electronic control units (ECUs). The engine, drive train, or entire vehicle is replaced with a behavioral model learned from a provided training data set. The model is used for offline simulations and virtual calibration of ECU control parameters, but its application is often limited beyond this use case of offline calibration. Depending on the underlying regression algorithm, limiting factors could include expensive computational calculations and a high memory demand. However, development and testing of new control strategies would benefit from the ability to execute such high fidelity plant models directly in real-time environments. For instance, map-based ECU functions could be replaced or enhanced by more accurate behavioral models, with the implementation of virtual sensors or online monitoring functions.

Motorcycle usage area keeps expanding in the world. Motorcycle filling with various fuels in all countries and regions has to compliance with emissions and fuel consumption regulations as UN-GTR No.2 (WMTC). In general, motorcycle engine has large bore diameter and high compression ratio due to demands of high performance. Poor fuel quality may cause damage to engine mainly by knocking. Knock control systems performing high-frequency vibration detection strategy like knock sensor, which are equipped on several sport-touring motorcycles, can not come to wide use for reasons of complex construct and cost. This research aims to develop a new concept of combustion control for common motorcycle as an instead.
