Won't allow driverless cars in India: Gadkari

Image
NEW DELHI: Union minister Nitin Gadkari   on Tuesday said he will not allow driverless car  in India as these could take away jobs  of several lakh people in the country .  "Several big personalities from the country met me and said they want to bring driverless vehicles to India . I clearly told them that till I am there, I shall not allow driverless cars in India. I was asked whether I oppose new technology. I said not at all. "There are 40 lakh drivers in the country and a shortage of 25 lakh drivers. I will not let the jobs of 1 crore people be snatched away," Gadkari said. The Union Minister for Road Transport & Highways and MSME  was addressing an event to distribute leather tool kits at a function organised by Khadi and Village Industries Commission (KVIC). Gadkari said that social and economic equality will not come from speeches but with real action. Distribution of tool kits to leather artisans is such an action. It is a real dedica...

An ADAS and autonomous-driving case study

Image
Zenuity is a small company with a large mission. This startup — launched by Volvo Cars and Veoneer, a subsidiary of automotive safety leader Autoliv — is developing advanced driver-assist systems (ADAS) and autonomous-driving (AD) technologies that promise to take vehicle safety systems to a new level. Zenuity is focused on the software side of the ADAS/AD problem. It enables smarter vehicles with a complete software stack, including algorithms for computer vision, sensor fusion, decision making and vehicle control, along with applications that run in the cloud. AI is at the heart of the Zenuity’s solutions, according to Dennis Nobelius, the company’s CEO. In an interview with  Automotive World , he notes that AI is one of the major trends driving advances in ADAS and AD systems. “We realize that we must be effective with the data that we generate and handle, and AI is really transforming the way we use that data and, therefore, how we operate software,” he says.

PID Controller unit

Image
      PID controller is a way to regulate an application to smoothly follow a value or a path. I first learnt the idea here, which introduced how to drive a car to follow a specific path. Although a full application explanation can be extensively complex, it summarised the math behind it in a super elegant and concise way, and made the idea can easily extended to many real life problems. In this post, let’s follow the key structure and explore how PID controller works.

Anand Mahindra to step down as Executive Chairman as company announces board succession plan

Image
       Mahindra & Mahindra (M&M) on Friday announced a rejig of its top management with Anand Mahindra, 64, transiting to the role of non-executive chairman from executive chairman, effective 1 April, 2020.

Based on its recommendations, the Board of Directors approved several decisions including the transition of Mahindra into the role of Non-Executive Chairman with effect from April 1, 2020 and his re-designation as a Non-Executive Chairman from the beginning of April 2020. Mahindra also took to Twitter to announce the same. "Delighted to announce our leadership transition plan which reflects the Group’s commitment to good governance," he wrote.        There were other restructuring moves taken too. Dr. Pawan Kumar Goenka will, from April 1, 2020, become ...

Karl Benz

Image
      Karl Friedrich Benz was an automobile engineer, engine designer, and entrepreneur from Germany who is remembered for designing the first practical automobile in history, Benz Patent Motorcar. He obtained a patent for it in 1886. A Mühlburg native, Benz grew up in an impoverished family after losing his father when he was quite young. Despite this, his mother made sure that he received a proper education. In 1864, he obtained a mechanical engineering degree from the University of Karlsruhe. Benz subsequently spent seven years acquiring professional training in various companies. In 1871, he co-founded his first factory, the Iron Foundry and Mechanical Workshop in Mannheim, which was later rebranded as Factory for Machines for Sheet-metal Working. During this period, he began developing his early inventions. In 1883, he established the Benz & Cie. to create stationary internal-combustion engines. Following the success of the three-wheeled vehicle, the Motorwag...

Predictive Vehicle Technology

Image
      Artificial intelligence (AI) and machine learning (ML) have an important role  in the future of the automotive industry as predictive capabilities are becoming more prevalent in cars, personalizing the driving experience. More manufacturers are applying algorithms that use data to automate the process of setting up a vehicle, including a car’s infotainment system and its application preferences. Vehicles are becoming IoT devices that can connect to smartphones and take voice commands, changing the user interface.       Predictive vehicle technology can also be used in the form of sensors within a car that informs the owner whether or not the vehicle needs service from a mechanic. Depending on your car’s mileage and condition, the technology will be able to estimate its performance, set up appointments in real-time and inform users of any safety hazards linked with a malfunctioning car due to company recalls.

Odometer

Image
       Mechanical odometers have been counting the miles for centuries. Although they are a dying breed, they are incredibly cool because they are so simple! A mechanical odometer is nothing more than a  gear train  with an incredible gear  ratio.          The odometer we took apart for this article (pictured above) has a 1690:1 gear reduction ! That means the input shaft of this odometer has to spin 1,690 times before the odometer will register 1 mile. Odometers like this are being replaced by digital odometers that provide more features and cost less, but they aren't nearly as cool. In this article, we'll take a look inside a mechanical odometer, and then we'll talk about how digital odometers work.

How BS VI ( Bharat Stage VI ) is different from BS IV?

Image
       The Bharat Stage Emissions Standards   (BSES)  was introduced in the year 2000 are automotive emissions standards mandated by the government of India to keep a check on air pollutants from an internal combustion engine in a vehicle. These standards are set by the Central Pollution Control Board  under the Ministry of Environment and Climate change.        The BS (Bharat Stage) norms are based on  EURO (European)  emissions standards. The “India 2000” was rolled out in the year 2000, followed by BS2 and BS3 in 2001 and 2005 respectively. It wasn’t until BS4 (4th stage) (BSIV), that more stringent emissions mandates were enforced. In 2016, the government of India decided to skip BS5 altogether and implement Bharat Stage 6 (BS 6) by the year 2020.               The Bharat Stage 6 (BSVI) norm is the sixth mandate for vehicular emissions and a much welcome change amidst the ...

More Fuel-Efficient technology

Image
             Tesla is at the forefront of the fuel-efficiency movement, releasing a slew of electric and hybrid vehicles that can take you for hundreds of miles with a single charge. In 2016, more than 2 million electric vehicles were sold worldwide and this figure is expected to rise in the near future as more automotive manufacturers implement electric vehicle technology to their fold. Companies such as VW and General Motors have recently unveiled electric cars to their fleet, while Volvo said that all of the engines they produce will be equipped with an electric motor by 2019.       Electric vehicles are also becoming more affordable, with companies such as Hyundai, Kia and Toyota unveiling hybrid cars under the $30,000 mark, suggesting that investing in fuel efficiency may soon be widely adopted around the globe. In the U.S., 20% to 25% of all vehicle sales are expected to be electric by 2030, while this figure is e...

Adaptive Cruise Control

Image
       Adaptive cruise control   ( ACC ) is an available  cruise control   system for  the road vehicles   that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead. As of 2019, it is also called by 20 unique names that describe that basic functionality. This is also known as Dynamic cruise control.        Control is based on sensor  information   from   on-board  sensors . Such systems may use a radar or laser  sensor or a  camera   setup allowing the vehicle to brake when it detects the car is approaching another vehicle ahead, then accelerate when traffic allows it to.        ACC technology is widely regarded as a key component of future generations of intelligent cars . The impact of driver safety   and convenience as well as an increasing road capacity   by maintaining optimal separation between vehicles and red...
