1081 Words5 Pages

Literature Review: Driving is one of the most challenging activity. The driver has to focus and concentrate for a large period of time and he has to be prepared for a difficult situations that can occur within a seconds. The drivers have to continually evaluate or judge the distance and speed of the obstacle or vehicle in front of them and alter their speed as the situation requires.
Nowadays accidents are very common on our roadways. Thus to prevent these accidents different approaches has been made for safety of the driver. These approaches include Emergency Braking System (EBS), Stability Control and Traction Control [1]. Infrared (IR) sensors were also as a proximity sensors for detecting an obstacle in front of the vehicle, [2] however …show more content…

Different theories and design has been inducted for the purposes. Some of them are discussed below.

The Google Driverless Car:
[1] “The Google Driverless Car” is the project proposed by google which relates to the modern technology i.e. autonomous car. Google Chauffeur is the software which powers these cars. The project is in process and it is led by an engineer in google names as Sebastian Thrun, who is the director of the Stanford Artificial intelligence Laboratory and also a co-inventor of Google Street View.
[2] An associate professor of engineering Dennis W.Hong at Virginia tech is currently working on the project that is designed for blind people. This project aims to provide a normal life to blind people by making them drive a vehicle and providing them comfort to live a normal life.
[3] Mercedes Benz is currently working on the project i.e. Attention Assist and Distronic PLUS with Pre-Safe Brake for vehicles to prevent imminent …show more content…

The luxury brand of Honda in Canada and US, employs a radar-based system to observe the situation and offer an automatic braking, if the driver does not take any action on the warning. Hondo was the first automobile company to provide automatic braking. CMBS has three phases, in the first phase system warns the driver to apply brakes. If the driver ignores the warning, the system then tug on the shoulders as the last sign of warning. Then comes the last phase in which system applies brakes automatically and tighten up seat belts for protection and reduce the severity of the accident.
In late 2004, Intelligent Night Vision System was introduced by Honda, which monitors pedestrians in front of the vehicle and warn the driver by buzzing tune or by visualizing them via HUD. This system can only be employed in conditions where temperature is below 30 degree Celsius.

2.4 Nissan
Luxury Brand of Nissan in North America and Europe, provides a laser based system in the US market. Nissan has been working on the Magic Bumper system which applies brakes automatically when the driver lifts the pedal off.

Drawbacks in existing approaches:-
1. Inconsistent stop times: Direction of our vehicle is monitored by ABS which ultimately helps us to prevent the obstacle on the roadway. The ABS decreases braking distance on dry or wet roads however it increases when applying brakes on snowy roads
