Cruise control simulation using matlab
Cruise control systems use feedback control to maintain a constant vehicle speed set by the driver. A cruise control system measures the current vehicle speed, compares it to the desired speed, and automatically adjusts the throttle according to a control law to account for external disturbances. Modeling the vehicle as a first order mass-damper system and applying Newton's second law derives the system transfer function. A proportional controller meets some performance criteria, but a lag controller is also needed to reduce the steady-state error to within acceptable limits.
Cruise control systems
Cruise control is a system that automatically controls the speed of a vehicle to maintain a steady speed set by the driver. It works using radar to determine the distance between vehicles and accelerate or decelerate accordingly to keep the desired speed. Adaptive cruise control can also adjust speed based on traffic conditions, detecting the vehicle ahead through radar or lidar sensors. While improving comfort and safety, cruise control still poses some dangers, especially on wet roads, but cooperative adaptive cruise control tested in California shows promise for the future.
Cruise control devices
This document provides an overview of cruise control devices and Adaptive Cruise Control (ACC) systems. It discusses how ACC uses lidar or radar sensors to detect the distance and speed of vehicles ahead to maintain a safe following distance. The document outlines the key components of an ACC system, including sensors, longitudinal controllers, and options like lidar and radar. It describes how ACC offers two control types - speed or headway control - and discusses future possibilities like Cooperative Adaptive Cruise Control that could coordinate vehicle speeds. In conclusion, the document suggests ACC may eventually make car accidents as rare as plane accidents through intelligent vehicle control and changes to road laws.

Cruise control & Adaptive Cruise Control
Cruise control systems maintain a set driving speed without driver intervention. Modern systems use electronic throttle control and sensors to monitor speed. When engaged, the cruise control actuator adjusts the throttle linkage to accelerate or decelerate the vehicle as needed to keep the set speed. Drivers can set the speed and engage/disengage cruise control using buttons on the steering wheel or controls on the turn signal stalk. Cruise control benefits long highway drives but has limitations in varying traffic or weather conditions where maintaining a constant speed is difficult.

Adaptive cruise control (ACC) uses radar and other sensors to detect vehicles ahead and maintain a safe following distance without requiring driver input. It works by detecting the distance and speed of other vehicles using radar and adjusting the vehicle's speed using the brake and throttle to keep a safe distance. Newer ACC systems fuse radar and camera sensors to better track vehicles. The controller processes sensor data and controls the engine or brakes. ACC allows more comfortable driving in traffic while increasing safety and fuel efficiency.
Advanced Safety Feature Adaptive Cruise Control
Among the recent advancements in car safety technologies, the adaptive cruise control feature is one of the most important and useful. It greatly minimizes the pressure of the driver as it helps to control the speed of the car and maintains a safe distance from other cars to avoid a crash. But still, this adaptive control should not be used in bad weather conditions and in tunnels as they might not work efficiently. So, if you want to know all about the adaptive cruise control system in your car, then give some time to watch the following slide show.
Cruise control devices
Adaptive cruise control devices use sensors like LIDAR or RADAR to detect vehicles ahead and allow a vehicle to maintain a set following distance. In cooperative adaptive cruise control (CACC), vehicles can communicate with each other to coordinate speed and braking rates more quickly and reliably than autonomous sensing alone. This allows for safer and closer vehicle spacing in traffic while increasing fuel efficiency through more systematic acceleration and braking. However, high market penetration is required for full benefits and there are concerns about driver complacency or accidents if the system malfunctions.

Uas-15008-a-slides for PDR
The document presents the preliminary design review for the MACH.E.T.E unmanned aerial system. It describes the system's aim of providing laser designation capability for precision strikes. It then summarizes the aircraft and ground segment designs, including dimensions, components, and performance parameters like range and endurance. Key systems like the electric propulsion and laser targeting equipment are also overviewed. Design requirements and risks are addressed.
Microprocessor based autonomous control system
The document describes a microprocessor-based autonomous control system developed for longwall coal mining shearers. The system aims to control the load on the cutter motor by regulating the haulage speed of the shearer. It does this by continuously monitoring sensors that measure current, voltage, power, and speed, and using a programmed algorithm to adjust the variable speed drive controlling the haulage motor as needed to prevent overloading. The system was tested through field investigations and laboratory experiments.

Air-Bag system
An air bag system deploys within 0.2 seconds of a crash being initiated. Crash sensors detect the impact within 0.015 seconds and send data to the integrated controller. The controller evaluates the data by 0.016 seconds and determines if airbag deployment is needed. If so, automatic belt tensioners activate at 0.017 seconds and the driver and passenger side airbags deploy by 0.018 seconds. Servicing the air bag system requires disconnecting the clock spring assembly and power module for safety, with diagnosis done through reading flash codes or pinpoint testing with a digital volt ohm meter.
Turbocharger and Supercharger
The document discusses turbochargers and superchargers. It begins by explaining how engine power depends on air intake and efficiency. It then describes three methods to increase air consumption: increasing displacement, running at higher speeds, and increasing charge density. Superchargers and turbochargers both increase charge density by compressing air intake. A supercharger is mechanically driven while a turbocharger uses exhaust gas energy. The document outlines the components, working principles, advantages, disadvantages, and selection process for turbochargers. It also presents experimental results showing increased torque, power, and reduced exhaust temperatures from a turbocharged tractor engine compared to naturally aspirated.
Suspension system
The document discusses various components and types of vehicle suspension systems. It describes solid axle, double wishbone, and MacPherson strut suspensions. For each type it provides the advantages and disadvantages. It explains key suspension terminology like camber, caster, roll center, and discusses how suspension serves to isolate passengers from road vibrations while improving vehicle control and mobility.
Steering system
The steering system controls the direction of front wheels to steer the vehicle. It transmits road feedback and absorbs shocks from the road surface. The main types are linkage steering using a worm gear and rack-and-pinion steering. Linkage steering uses a steering shaft, column, gearbox and linkage to connect the steering wheel to the wheels. Rack-and-pinion steering uses a pinion gear that engages a toothed rack to directly turn the wheels. Power steering systems use hydraulic pressure to assist the driver. Common problems include steering wheel play, hard steering, and noises from low fluid, worn belts or the power steering pump.
Disc brakes
This document discusses the main components of automotive disc brakes, including the mounting bracket, rotor, caliper, and pads. It describes the purpose and basic operation of each part. The rotor comes in vented and non-vented varieties and can require repair work like truing. Calipers are either fixed or floating and contain pistons and seals. Disc brakes are self-adjusting, and wear indicators help detect when pads need replacement. Common brake issues like noise, pulsation, and excessive pedal travel are also briefly mentioned.
Four-wheel drive
This document discusses four-wheel drive (4WD) vehicles. It describes the main advantages as improved traction and handling from being able to transmit torque to all four wheels. The disadvantages include higher initial costs and weight as well as requiring special service and maintenance. The document defines different 4WD systems such as part-time 4WD which operates in two-wheel drive normally but can engage 4WD, full-time 4WD which constantly powers all four wheels, and on-demand 4WD which automatically engages the front wheels when slip is detected. It provides details on 4WD components, transfer cases, differentials, and maintenance tips.
Electronic fuel injection
This document discusses electronic fuel injection systems used in vehicles. It describes how computers precisely control fuel injectors based on various engine parameters to meet emission standards. It outlines different EFI systems including throttle body injection, multi-port fuel injection, and centralized port injection. It details the components involved like fuel injectors, fuel rails, and pressure regulators that work together to deliver the optimal air-fuel ratio for all driving conditions.
Gears and Transmissions
Transmissions allow engines to operate at optimal RPM for efficiency using gear ratios to reduce RPM and multiply torque. They contain gears that change the speed and direction of rotation. Planetary gears, common in automatic transmissions, use three components - sun gear, planet gears, and ring gear. By holding one component and driving another, different gear ratios are achieved like underdrive, overdrive, and reverse. Ratios are calculated using the number of teeth on each component.
Anti-Lock braking system
Anti-lock braking systems (ABS) use sensors and computer control to prevent wheels from locking up during hard braking. ABS monitors wheel speed and selectively applies and releases brake pressure to allow steering control. It consists of a brake control module, solenoid valves, speed sensors, and wiring. When braking hard, ABS pulses the brakes faster than the driver can to prevent skidding and maintain steering ability.
The invention of automobile
The automobile was first produced in America in the 1890s, but it was not until Henry Ford introduced the assembly line method of production that cars became affordable for the masses. Ford was able to reduce the price of the Model T to just $600 in 1908 due to the assembly line, and by paying workers $5 per day, enough to purchase a car. By 1920, Ford had sold millions of affordable Model T cars, transforming transportation and enabling the development of highways, suburbs, and a mobile society across America.
