With this technique, arbitrary linearization functions can be selected simply. The proposed digital linearization method overcomes many of the pitfalls of traditional linearization methods, at the expense of some additional hardware and more stringent requirements on the internal voltage reference. The technique can be extended to meet necessary accuracy requirements, though the principal application is low-cost display instrumentation. As a result of this linearization method, a linear output voltage is available for recording or display. A survey of conventional techniques for signal linearization is presented, followed by a description of the proposed technique, including design considerations. A typical application example is included.<<ETX>>","PeriodicalId":125786,"journal":{"name":"1988., IEEE Workshop on Automotive Applications of Electronics","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129972880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal of the design is efficient computation of mathematically oriented algorithms with the ability to interface with sensors and actuators. The effectiveness of the system architecture was demonstrated by a real-time fast-Fourier-transform application to road characterization and by state estimation of a quarter car test rig. Also shown was the ability of such controllers to handle modern control theory requirements as applied to an optimal active suspension control.<<ETX>>","PeriodicalId":125786,"journal":{"name":"1988., IEEE Workshop on Automotive Applications of Electronics","volume":"64 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125567469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors determining the choice of a particular technology are examined, and attention is given to product design, output configurations, and output protection. It is concluded that those components which must interface directly with the vehicle's supply or system input/outputs need to utilize an appropriate power integrated circuit technology to meet supply and input/output requirements. The demands for increased protection, a safe operating area, and reliability must be addressed at the design level in order to respond to present and future challenges of higher quality and reliability demanded by competitive pressures, such as extended warranties, while meeting cost and performance objectives.<<ETX>>","PeriodicalId":125786,"journal":{"name":"1988., IEEE Workshop on Automotive Applications of Electronics","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114068023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process simultaneously produces CMOS (complementary metal-oxide-semiconductor) logic with a PNP vertical power device. The combination can withstand transients in excess of 85 V and jump start (24 V) and reverse polarity conditions while controlling several amperes of current, making it ideal for automotive applications. Two production devices and a new product that have been developed using the BiMOS (bipolar MOS) process are described: (1) a high-side switch that is used for controlling inductive loads; (2) a transient suppressor used to protect voltage-sensitive electronic components; and (3) a low-side, protected driver.<<ETX>>","PeriodicalId":125786,"journal":{"name":"1988., IEEE Workshop on Automotive Applications of Electronics","volume":"122 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131435874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A direct multiplexed full-color LCD having 320*200 trio dots was developed and applied to a graphic display unit. Through the use of the newly developed COG (chip-on-glass) technology, a small and thin display module was realized. A route guidance indicator was developed using a segment-type LDC and a monochromatic dot-matrix LCD, and it was applied to an actual automotive navigation system. This indicator displays such information as the form and name of crossings as a car approaches it. Not only can it show the extracted principle information, but it can also be mounted at a place near the driver's regular eye position. For these reasons, this indicator is useful for improving the information cognitivity of navigation systems.<<ETX>>","PeriodicalId":125786,"journal":{"name":"1988., IEEE Workshop on Automotive Applications of Electronics","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131846810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Control of static body parameters is implemented by using a single-bit serial bus. Dynamic parameters such as the fuel/air mixture and spark timing are controlled by monitoring the sensor readings and executing control routines. The concept of diagnostics is emphasized both for static and dynamic parameters. The diagnostic status of various units is stored in memory.
