R134a Refrigerant Charge Determination Test Method

2018-09-11
CURRENT
J3023_201809
The purpose of this document is to establish guidelines for determining the critical R134a refrigerant charge for off-road, self-propelled work machines as defined in SAE J1116 and Agricultural Tractors as defined in ANSI/ASAE S390. It will develop a minimum to maximum refrigerant charge range in which the HVAC system can maintain proper operation. Operating conditions and characteristics of the equipment will influence the optimum charge. Since these conditions and characteristics vary greatly from one application to another, careful consideration should be taken to determine the optimum R134a refrigerant charge for the HVAC system.

Nonlinear and Hybrid Systems in Automotive Control

2003-05-01
A new generation of strategies for vehicle and engine control systems has become necessary because of increasing requirements for accuracy, ride, comfort, safety, complexity, and emission levels. In contrast with earlier systems, new control systems are based on dynamic physical models and the principles of advanced nonlinear control. With contributions from leading scientists in the field, this book presents an overview of research in this rapidly-expanding area. New approaches to solving theoretical problems, as well as numerous systems and control research issues, are covered.

Voltage Regulators for Automotive-Type Generators

2006-01-09
CURRENT
J2669_200601
This SAE Definition Document contains historic voltage regulation methods and test requirements that have not been previously published. The purpose of this document is to recommend a set of definitions and practices for use on current and future 12 V vehicle electric power regulation and control systems in internal combustion engine road vehicles. This document is not intended to include nor exclude regulators used in higher voltage vehicle electrical systems. The term “generator” rather than “alternator” will be used even though these terms may be used interchangeably in practice.

Brake Hydraulic Component Flow Rate Measurement for High Differential Pressure (>5 bar)

2017-05-18
CURRENT
J3052_201705
This recommended practice provides a method, test set-up, and test conditions for brake hydraulic component flow rate measurement for high differential pressure (>5 bar) flow conditions. It is intended for hydraulic brake components which affect the brake fluid flow characteristics in a hydraulic brake circuit, that are part of a circuit for which the flow characteristics are important to system operation, and that are exposed to high operating pressure differentials (in the 5 to 100 bar range). Typical applications may include measurement of flow through chassis controls valve bodies, orifices in the brake system such as in flow bolts, junction blocks, and master cylinders, and through brake pipe configurations.

MANUAL CONTROLS FOR MATURE DRIVERS

1997-10-01
CURRENT
J2119_199710
Since little data exists to provide appropriate values for control parameters that would be appropriate for mature drivers, the following recommendations are of a general nature. However, they are based upon the current understanding of the aging processes that characterize mature drivers. Notwithstanding the lack of an extensive amount of data in this field, the dissemination of this SAE Information Report is considered to be appropriate and timely in light of the large increase in the number of mature drivers on the public roads, and because of the need to at least initiate efforts toward developing an information report covering this issue. It is realized that there may be cases where specific recommendations may conflict with vehicle packaging and/or operational requirements. Deviation from the recommendations may be necessary and permissible to achieve the best overall system performance.

Secondary Control Modifications

2011-10-05
CURRENT
J2388_201110
This SAE Recommended Practice establishes a uniform procedure for assuring the manufactured quality, installed utility and performance of automotive products to the relocation, alteration, replacement and/or extension of secondary controls and systems other than those provided by the vehicle manufacturer (OEM). These products are intended to provide driving capability to persons with physical disabilities. These products function as adaptive modifications to compensate for lost or reduced function in the extremities of the driver. These include, but are not limited to the following: Cruise Control; Door Locks; Gear Selector; Hazard Flasher; Headlight Beam Selector; Heater/Vent/Air Conditioner (HVAC); Horn; Ignition/Starter; Light controls; Mirrors; Parking Brake; Power Seats; Turn Signals; Power Window Controls; and Windshield Wiper/Washer and defogger; Rear Accessories (Defogger, Wiper/Washer).

Electric Motors for Hybrid and Pure Electric Vehicles 2015-2025: Land, Water, Air

2014-11-01
The electric vehicle business will approach a massive $500 billion in 2025 with the traction motors segment capturing over $25 billion. Traction motors propelling land, water and air vehicles along can consist of one inboard motor or - an increasing trend - more than one near the wheels, in the wheels, in the transmission or ganged to get extra power. Complex trends in this industry are explained with this updated report, and future winning suppliers are identified alongside market forecasts. The information is especially important as hybrid vehicles may have the electric motor near the conventional engine or its exhaust, and this may mean they need to tolerate temperatures never before encountered in pure electric vehicles. Motors for highly price-sensitive markets such as electric bikes, scooters, e-rickshaws and micro EVs avoid the price hikes of neodymium and other rare earths in the magnets.

Remote Steering Control Systems

2004-08-12
CURRENT
J2588_200408
This SAE Information Report establishes a uniform procedure for assuring the manufactured quality, installed utility and performance of automotive remote steering controls other than those provided by the vehicle manufacturer (OEM). These products are intended to provide driving capability to persons with physical disabilities. The adaptive modifications seek to compensate for lost or reduced function in the extremities of the driver with a disability. Remote steering controls are designed to provide a steering input device alternative to the OEM steering wheel that either reduces the required input force, changes the required range of motion or changes the location of the steering control or any combination of the above. These controls supplement by power, other than by the driver’s own muscular efforts, the force output of the driver with a disability.
