In this respect and beside all technical and physical aspects, the human factor plays a major role for the development of this Advanced Driver Assistance Systems (ADAS) integral assistance concept. Basis for the assist the driver during the driving task to improve development of this assistance concept were subject the driving comfort and therefore indirectly traffic driver vehicle tests to study the typical driver safety, ACC (Adaptive Cruise Control) is a typical behavior in emergency situations. Objective example for a “Comfort ADAS” system. “Safety was on the one hand to analyze the relevant ADAS” directly target the improvement of safety, parameters influencing the driver decision for brake such as a forward collision warning or other and/or steer maneuvers. On the other hand the systems which assist the driver during an evaluation should result in a proposal for a emergency situation. A typical application for a preferable test setup, which can be used for use case “Safety ADAS” is EBA (Emergency Brake Assist), evasion and/or braking tests to clearly evaluate the which additionally integrates information of benefit of the system and the acceptance of normal surrounding sensors into the system function. drivers.

The Starting System Includes the Battery, Starter Motor, Solenoid, Ignition Switch and in Some Cases, a Starter Relay
UNIT II STARTING SYSTEM &CHARGING SYSTEM The starting system: The starting system includes the battery, starter motor, solenoid, ignition switch and in some cases, a starter relay. An inhibitor or a neutral safety switch is included in the starting system circuit to prevent the vehicle from being started while in gear. When the ignition key is turned to the start position, current flows and energizes the starter's solenoid coil. The energized coil becomes an electromagnet which pulls the plunger into the coil. The plunger closes a set of contacts which allow high current to reach the starter motor. The charging system: The charging system consists of an alternator (generator), drive belt, battery, voltage regulator and the associated wiring. The charging system, like the starting system is a series circuit with the battery wired in parallel. After the engine is started and running, the alternator takes over as the source of power and the battery then becomes part of the load on the charging system. The alternator, which is driven by the belt, consists of a rotating coil of laminated wire called the rotor. Surrounding the rotor are more coils of laminated wire that remain stationary (called stator) just inside the alternator case. When current is passed through the rotor via the slip rings and brushes, the rotor becomes a rotating magnet having a magnetic field. When a magnetic field passes through a conductor (the stator), alternating current (A/C) is generated. This A/C current is rectified, turned into direct current (D/C), by the diodes located within the alternator. -
Development of Two-Stage Electric Turbocharging System for Automobiles
Mitsubishi Heavy Industries Technical Review Vol. 52 No. 1 (March 2015) 71 Development of Two-stage Electric Turbocharging system for Automobiles BYEONGIL AN*1 NAOMICHI SHIBATA*2 HIROSHI SUZUKI*3 MOTOKI EBISU*1 Engine downsizing using supercharging is progressing to cope with tightening global environmental regulations. In addition, further improvement in fuel consumption is expected with such applications as ultra-high EGR, Miller cycle, and lean combustion. Mitsubishi Heavy Industries, Ltd. (MHI) has developed a two-stage electric turbocharging system to balance better drivability and improved fuel consumption by increasing the turbocharging pressure and improving the transient response. |1. Introduction Engine downsizing/downspeeding through supercharging is progressing to cope with annually enhanced improvement in fuel consumption and exhaust gas. Downsizing through direct injection and supercharging has been developed mainly in European countries where the CO2 regulations are the most stringent, and it has expedited the increase of the turbocharger installation rate in other areas. Diesel vehicles are supposed to satisfy the CO2 and exhaust gas regulation standards in 2021. However, gasoline vehicles are still not able to meet the standards even in the case of low-fuel consumption vehicles with supercharged downsizing, and further measures are required. The adoption of WLTC (Worldwide harmonized Light duty driving Test Cycle) is planned globally in and after 2017, and new regulations taking actual driving conditions into consideration are being discussed. Turbochargers are required to provide a further boost pressure and better response, as well as robust and easy to operate characteristics, for this purpose. Existing turbochargers have a time-lag and EGR response delay, and proper control is difficult. -

Subframe Design General
Subframe design General General The subframe can be used for the following purposes: • It provides clearance for wheels and other parts which protrude above the frame. • It provides rigidity and reduces the stress in the rear overhang. • It protects the chassis frame by distributing the load from the bodywork evenly over a larger area of the chassis frame. • It contributes to dampening frame oscillations that cause discomfort. To adapt the subframe to the torsionally flexible part of the chassis frame, the sub- frame should also be torsionally flexible, provided the bodywork allows it. There- fore, the side members and crossmembers of the subframe should consist mainly of open profiles, e.g. U-profiles. 376 530 More information on chassis frames is found in the document Chassis frames. More information on chassis frames and subframes is found in the document Select- ing the subframe and attachment. More information on the concepts of torsional rigidity and torsional flexibility is found in the document Forces and movements. Scania Truck Bodybuilder 22:10-649 Issue 2 2016-09-02 © Scania CV AB 2016, Sweden 1 (8) Subframe design General The subframe can appear differently depending on the characteristics required. The subframe length can vary. It can cover the whole chassis frame or be short and only cover part of the chassis frame. The height of the chassis frame can be adjusted to the current area of application. 376 541 Example of a subframe.

In 1902 a Renault Type K won its first victory in the Paris-to-Vienna road race, propelled by a four cylinder engine producing slightly more than 40 horsepower. It beat the more powerful Mercedes and Panhard racers because they broke down, proving very early on that to finish first, first you have to finish. In that same year Renault patented the turbocharger, something it had not forgotten in 1977 when it was the first manufacturer to race a turbocharged Formula One car. The RS01 was initially nicknamed the 'Yellow Teapot' by amused rival teams, but intensive development eventually saw it scoring fourth place in the 1978 US Grand Prix, and a pole position the following year. Within three years of the Yellow Teapot’s arrival most rival teams were also using turbochargers. Although today’s Renaultsport RS27-2013 engine is a normally aspirated V8, as required by the regulations, from 2014 it will be replaced by a highly advanced, downsized 1.6-litre turbocharged V6 featuring a pair of powerful energy recuperation systems that feed twin electric motors. These include an Energy Recovery System (ERS-K) that harvests Kinetic energy, and a second Energy Recovery System (ERS-H) that captures Heat. -

An Abstract of Design, Analysis and Optimization of Rear Sub-frame using Finite Element Modeling and Modal Analysis by Gaurav Kesireddy Submitted to the Graduate Faculty as partial fulfillment of the requirements for the Master of Science Degree in Mechanical Engineering The University of Toledo May 2017 A sub-frame is a structural component of an automobile that carries suspension, exhaust, engine room, etc. The sub-frame is generally bolted to Body in White(BIW). It is sometimes equipped with springs and bushes to dampen vibration. The principal purposes of using a sub-frame are, to spread high chassis loads over a wide area of relatively thin sheet metal of a monocoque body shell, and to isolate vibration and harshness from the rest of the body. As a natural development from a car with a full chassis, separate front and rear sub-frames are used in modern vehicles to reduce the overall weight and cost. In addition, a sub-frame yields benefits to production in that subassemblies can be made which can be introduced to the main body shell when required on an automated line. -
