ADAPTIVE CRUISE CONTROL


 


  •            Some cool technologies enhance the safety of vehicles and ease of driving. One among those named ADAPTIVE CRUISE CONTROL had fascinated the drivers in assisting for convenience in long highway driving. This Technology can be seen in every premium car and presently even in budget segments too. These coolest technologies find the trend of the next generation.
WHAT IS MEANT BY ADAPTIVE CRUISE CONTROL?

          Adaptive cruise control can take over the controls of acceleration and braking in highway driving with certain preset instructions from the driver (Distance maintained from the vehicle ahead, speed should be maintained) so, that the driver can take off his foot from the pedals and enjoy the cruising with convenience. ACC(Adaptive Cruise Control) is also called by 20 unique names.


HOW STANDARDS DESCRIBE ADAPTIVE CRUISE CONTROL?

            As per the standard scale adopted by the Society of Automotive Engineers this adaptive cruise control technology takes the LEVEL 1 automation. This level describes that this tech can assist the driver in a specific situation and will not take over at all times.


SIMPLE WORKING OF ADAPTIVE CRUISE CONTROL SYSTEM.

  •  The operation of this autonomous system completely depends upon the instructions from the control systems. The control system is integrated with certain components like sensors, input device, controller, actuator, etc..,
  • At first, the control system of ACC stores the preset information from the driver, then it takes the input from the sensors and compares it with the preset value, and performs the relevant actions.       
For example: If the speed is preset to 50kmph and the vehicle speed is 45 kmph, and if  The vehicle has a safer distance from the vehicle in front the control system opens the throttle body further more and lets the vehicle accelerate. If the distance is too close to the vehicle in front it maintains the same safer speed.

  • RADAR and camera along with collision avoidance systems are used to assist the adaptive cruise control system.
  • If the electromagnetic energy from the radar reflects back to it in a short period of time the sensor senses that the vehicle approaching is not at a safer distance and allows the control system to retard the vehicle and vice versa.
  • These simple actions are repeated again and again and assist the driver with advanced safety and convenience.

Retarder braking system

Image
RETARDER BRAKING SYSTEM Breaking the truck generates high amount of pressure,wear and heat on the brake disks and brake pads and in some cases,continuous braking during downhill or in traffic leads to the decrease of brake pressure,The truck needs to halted in safe place to recharge the compressor. The best solutions for these safty less conflicts is the RETARDER BRAKING SYSTEM. The reatarder brake system gives the smooth braking experience with no energy loss,wear,noise while slowing down the heavy loaded trucks.It saves the maintainance cost on replacing the brake disks,linings and brake pads. HOW RETARDER WORKS? Retarder is a hydraulic system that is integrated into the output end of a truck’s gearbox and uses high-pressure oil as a braking medium Via a gear transmission, the Retarder acts on the output shaft of the gearbox and thus directly on the propeller shaft. Once the Retarder is applied, it generates a braking force on the propeller shaft corresponding to up to

IVTEC system

IVTEC SYSTEM . .  IVTEC stands for intelligent- variable valve timing and electronic lift control is a system developed by honda to increase the volumetric efficiency of an internal combustion engine, resulting in higher performance at lower RPM. Here the cam phasing is implemented by computer controlled, oil-driven adjustable cam sprocket or the electrically actuated cam phaser (it replaces the oil pressure actuated cam phaser). Thus, this system provides continuous cam phasing and discrete variable valve lift controls using CPS concept. This system consists of a camshaft with a centre high lift cam and outer low lift cams and associated rocker arms. For light load operation, the valves are operated by the two outer, low lift cams and associated rocker arms. For high power operation, hydraulic pressure is used to insert a pin to lock the middle rocker arm to the outer rocker arms for operation on the high lift cam. Cam phasing is accomplished with a hydraulic cam phaser.

Gate exam 2022 subjects for mechanical Engineering.

Image
WHAT IS GATE?                                                  The GATE is abbreviated as Graduate Aptitude Test in Engineering which is a national-wide exam of India, conducted by 7 IIT'S and IISc Bangalore. This exam is completely a computer-based test that tests for the comprehensive understanding of various subjects in the undergraduate program. This score is mainly required for admission for master's program in various IIT's IISc's and several other government-funded top colleges in India with financial assistance.  GATE score is very much important for recruiting graduate engineers in public sector units.            Cracking this exam is very much easy for those who have a complete application and aptitude-based knowledge in engineering subjects. Proper planning and hard work can get you a better rank in this test.     SYLLABUS FOR MECHANICAL ENGINEERING(ME)  SUBJECTS FOR ME:  GENERAL APTITUDE: Verbal aptitude, Quantitative aptitude, Analytical aptitude, Spatial
