Introduction to Development Procedure of Climate Control Algorithm for a Passenger Car

A novel semi-active control system for suspension systems of passenger car using Magnetorheological (MR) damper is introduced. The suspension system is considered as a massspring model with an eight-degrees-of-freedom, a passive damper and an active damper. The semi-active vibration control is designed to reduce the amplitude of automotive vibration caused by the alteration of road profile. The control mechanism is designed based on the optimal control algorithm, Linear Quadratic Regulator (LQR). In this system, the damping coefficient of the shock absorber changes actively trough inducing magnetic field. It is observed that utilizing the present control algorithm may significantly reduce the vibration response of the passenger car, thus, providing comfortable drive. The new developed suspension system may lead to design and manufacturing of passenger car in which the passenger may not feel the changes in road profile from highly bumpy to smooth profile.

Indirect Indicator

This article proposes a model biotechnical system and exposure control algorithm on the behavior of piglets using machine vision technology. The effective temperature of the indoor air is an indirect indicator of the favourable conditions for keeping animals. In this article, a hypothesis has been put forward: the management of the microclimate in the cattle-breeding premises should be based on direct indicators of the favourableness of the content. This indicator is appropriate to consider the behaviour of animals. Structurally functional schemes for the functioning of the biotechnical system of the cattle-breeding complex have been developed in the IDEF0 notation. An algorithm for controlling the irradiation of piglets and weaners based on the ethological character of the location of animals across the floor area is presented. This problem was not solved before. Algorithms for automatic control of electro technological processes in agriculture have not been encountered in the literature before. The developed principle of intelligent control allows optimal provision of comfortable conditions for keeping animals in real time. The results can be used to create and design of modern automatic climate control systems in livestock.

The Impact

Abstract This work investigates by simulations the impact of the use of Electrochromic (EC) windows in a modern wooden cabin with large window area in a colder climate. The climatic areas considered are 4 different locations in Norway. Three different automatic control systems were used and compared. The windows were alternatively equipped with a textile integrated external blind and an EC glass. The results show that the use of EC glass has a quantifiable impact in term of reduction of peak temperature by 2°C and reduction of number of hours with high indoor temperature. The control system that seems to perform better is based on external solar radiation. In the particular situation of a cabin, where the visual comfort and the surrounding view has the greatest importance, a more complex control algorithm needs to be developed.

Final Design

This paper describes in detail the original methods used in the design and development of a microprocessor-based climate control system for the XJ40 Jaguar car. It takes the concept of air conditioning and applies modern technology and materials to produce a unit for a new passenger car. It describes those areas of design where experience in automotive air conditioning has shown the need for improvement, and also explains the operational procedures. The theories presented can be used in any automotive application and lead through concept and development to a final design implementation.

Acceptable Range

Rumble strips (RS) are a countermeasure used to reduce roadway-departure crashes by providing audible and haptic alerts to the driver when a vehicle is departing the roadway. This study evaluated the feasibility of using sinusoidal RS as a substitute for more traditional rounded RS. A van, a passenger car, and a heavy vehicle were equipped with sound and vibration sensors to measure the interior noise and haptic feedback of each RS design. A set of typical conditions (with interior climate control fan and radio turned on) were also tested. Data from 75 RS strikes were analyzed. Experimental results demonstrated that the rounded RS doubled interior noise for the passenger car and van (11.3 dBA, 10.0 dBA) but the sinusoidal RS also generated a clearly noticeable interior alert for the passenger car and van (5.8 dBA, 4.6 dBA). The haptic alert provided an increase over the human perception threshold of vibration for all vehicles. The sinusoidal RS interior alert was detectable and within the acceptable range, but not clearly noticeable (5 dBA) when the climate control and radio were active. Alert levels for the rounded RS were >10 dBA, doubling the amount of interior noise for all ambient factor groups (11.2–14.4 dBA).
