Driven by the need for lower emissions, better fuel economy and higher efficiency, hybrid vehicles are appearing in many different configurations on today's roadways. While the powertrain components such as the drive motor, motor controller and cooling system are somewhat familiar to the automotive industry, the battery systems are a relatively unfamiliar aspect. This seminar will introduce participants to the concepts of hybrid vehicles, their missions and the role of batteries in fulfilling those requirements.
There is growing interest in the concept of a smart city and how these advanced technologies will improve the quality of living and make a city more attractive to visitors, commerce and industry. This course fills an unmet need for defining and explaining the relationship between connected and autonomous vehicles (CAVs) and smart city transportation. It is apparent that CAVs will achieve the best results when integrated with current and emerging urban infrastructure for transportation. This course addresses such integration from technology, organizational, policy and business model perspectives.
India witnessed 151 417 road deaths in the year 20181 and this alarming number is due to increased urbanization, motorization and per capita income. India is home to the 2nd largest road network in the world and accounts for the highest number of road deaths globally. Curbing the menace of road deaths requires tactical road safety policies and their effective implementation. The meagre availability of factual data regarding socio-economic loss due to road crashes is proving to be a hindrance to the ideation and implementation of the policies. The Planning Commission estimated the social costs of road accidents to be ₹ 55 000 crore in 1999-2000 which was roughly 3% of the country’s GDP and this value was revised to ₹ 100 000 crores in 2011. Absence of data regarding the loss in recent times due to road crashes have been a motivating factor to our study. Road deaths bring about a great deal of human suffering in terms of social, medical and economic costs.
Road traffic crashes kill 1.25 million people each year. Like all road traffic crashes, those involving powered two- and three-wheelers (PTWs) such as motorcycles, auto-rickshaw and e-bikes are often predictable and preventable, and should not be accepted as inevitable. Key risk factors for motorcycle and three-wheeler traffic injuries are non-use of helmets; vehicle speed; alcohol use; mixed traffic conditions; disobeying traffic rules; lack of traffic management; lack of protection from the vehicle itself during a crash; regular vehicle maintenance; and lack of safe riding or driving infrastructure for PTWs, such as poor road surfaces and roadside hazards. Reduction or elimination of the risks faced by PTW users is an important and achievable policy goal, and despite the existence of proven interventions to prevent PTW crashes, in many locations PTW safety does not attract the attention it merits.
In automotive systems that include one or more electrical and/or electronic (E/E) systems, it’s imperative that utmost care is given to the functional behavior at all times so as to reduce the probability of their malfunctioning. As there is a probability that the deviation can result in harm, adherence to ISO-26262 is mandatory. One such important safety requirement is Freedom From Interference(FFI). FFI for memory (mainly volatile memory- RAM) is under focus here. The intention is to prevent corruption/unintended modification of safety critical data (ASIL- A,B,C or D) by QM components. In automotive domain, the increasing complexity of modern vehicles and especially their E/E systems has made strides towards AUTOSAR projects, making them prevalent. This paper presents a method to partition RAM memory in such AUTOSAR projects, by activating the Memory Protection Unit(MPU) using the AUTOSAR configuration tool.
