This recommended practice is intended to provide industry technical personnel with an overview of vehicle speedometer system accuracy and offset requirements and odometer system accuracy requirements. Speedometer and odometer systems covered by this document are integrated into a vehicle's electrical and electronics system, assembled directly into the vehicle by the OEM, and use rotational data from at least one vehicle wheel that is appropriately converted into longitudinal vehicle speed and distance traveled information. This standard is limited to radial ply tires on new (as manufactured) cars, light trucks, and medium duty trucks. Other methods for measuring vehicle speed and distance traveled may be used provided they meet the performance recommendations herein. Any local market regulatory requirements must be met and shall supersede this document. Service parts are beyond the scope of this recommended practice.

Abstract Rapid advent of mobile air conditioning industry has witnessed a wide use of fixed displacement swash plate compressor due to its small size, compact structure and light weight. An accurate prediction of volumetric efficiency and power of compressor at early stages of design serves as a very useful information for designer. No work regarding the power and volumetric efficiency prediction for double headed fixed displacement swash plate compressor is reported in the existing literature. This paper presents a mathematical model for a double acting fixed displacement swash plate compressor with the objective of evaluating the shaft torque and volumetric efficiency of compressor. Shaft torque, in turn is a measure of compressor power. The geometrical description of swash plate yields a kinematic model to obtain the piston displacement as an explicit function of angle of rotation of shaft.

Abstract New generation automobiles are equipped with power windows which eases the passenger’s effort in moving the vehicle windows up and down. Many of them are stuffed with advanced features like automatic up/down option for ensuring functionality with a single press of the switch. Even though it adds comfort to driver & passenger, inadvertent use of power window can be fatal if a person’s body part gets trapped inside. An effective solution for this problem is anti-pinch mechanism, which releases the object safely just when it gets trapped. It detects the object trapped and immediately moves the window down so that trapped object will get released easily. The anti-pinch algorithm used in this project is based on the “Method of Monitoring Movable Element”, method monitor traveling distance of a power window pane. In order to achieve this different from conventional techniques we are using Ultrasonic sensor.

Abstract In automotive seating, there are multiple applications wherein parts have relative motions. During the relative motion of parts, noise is generated due to friction which can be irritant to the end user. This paper focuses on, one such application where conventional noise reduction solutions like grease application are not very effective. Typically, Seats can have two types of Head Restraint, a) Adjustable, b) Non Adjustable. In Adjustable type of Head restraint, during adjustment by the end user, head restraint rod rubs against the metal plate inside the locking guide. This creates friction and that in turn results in noise. The paper focuses on understand the phenomenon of noise, identifying the root cause and studying about potential solutions to reduce the noise to acceptable level. In this paper, parameters affecting the noise are studied and evaluated.

Abstract This paper presents development and verification of an analytical model for a standalone performance study of mini-channel evaporator controlled with thermostatic expansion valve (TXV) for R134a mobile air-conditioning system. The analytical model was developed and validated using MATLAB program. In the existing literatures, studies of analytical evaporator model integrated with TXV for standalone performance was very limited. Effort has been considered to integrate TXV and evaporator model i.e. when there is a change in air flow rate, TXV adjusts refrigerant mass flow rate based on heat load and operating superheat. The developed analytical model emphasize on prediction of refrigerant mass flow rate, heat transfer and refrigerant side pressure drop characteristics. In-tube refrigerant flow was divided into two-phase region and superheated region, considering both dry and wet condition of effectiveness - NTU method.

Abstract Demand of hybrid vehicle increases more and more due to raise in fossils fuel prices. Automotive OEM’s of worldwide invest their potential in developing automobiles with higher fuel efficiency, light weight, comfortable and low cost as possible without negotiation in quality and safety. Air conditioner systems in buses utilizes 30% of power from engines for functioning of its components which increases the fuel consumption and decreases effective performance. In this project, Organic phase change material (PCM) paraffin 14-carbon with blend of 1.0 %wt of copper oxide (CuO)/titanium oxide (TiO2) nanoparticles dispersed fluid is used to store cooling energy in form of latent thermal heat. This composite material is filled in Aluminium shell of thickness 3mm and fixed in direct contact with refrigerant cycle. The newly developed PCM sample is subjected to differential scanning calorimetry (DSC) in order to determine phase change temperature and latent heats.

Abstract The OEM's aim is to reduce development time and testing cost, hence the objective behind this work is to achieve a flexible stateflow model so that changes in the application during supply chain or development, on adding/deleting any switches, varying timer cycle, changing the logic for future advancements or else using the logic in different application, would end in minimal changes in the chart or in its states which would reflect least changes in the code. This research is about designing state machine architecture for chime/buzzer warning system and wiper/washer motor control system. The chime/buzzer stateflow chart includes various input switches like ignition, parking, seat belt buckle, driver door and speed accompanied with warning in the form of LED, lamp and buzzer. The logic is differentiated according to gentle and strong warning. Various conditions and scenarios of the vehicle and driver are considered for driver door and seat belt which is resolved in the chart.

Abstract For effective occupant protection, automotive vehicle structure needs to be developed for seat anchorage test to prevent the failure of seat anchorages during high speed impacts. Seat anchorages (SA) certification test is mandatory for M & N category vehicles in India. Conventional way of testing automotive vehicle structures for seat anchorage test is using deceleration sled with the help of bungee ropes. Deceleration pulse generated from the physical test is used as a loading input in the current CAE process. With the current CAE method, final deformation of the vehicle structure looks similar to physical test, however, the vehicle visual interactions differ significantly during the deformation event. In the current study, a modified loading methodology is proposed to match both the final deformation as well as vehicle visual interactions. Loading and boundary conditions of physical test were understood in detail with the help of simple free body diagrams.

Abstract The cabin or cab is an enclosed space where the driver and co-driver are seated. Structural parameters such as modal and stiffness characteristics are of key importance for its durability study and driver’s comfort. The desired strength and stiffness value of the cabin have to be met at the development phase itself. In developing new cabin models numerical simulations are used for estimating vehicle performance to reduce the development cycle. But, the conventional method of modeling the cabin using 2-d elements and performing subsequent iteration steps to arrive at the desired stiffness and strength value will be cumbersome and time consuming. Thus, a methodology of FE modeling of the truck cabin using 1-D elements has been proposed in this paper which will reduce the analysis time of successive iterations. For this purpose an existing proven driver’s cabin is modeled using 1-D elements.
