Brake System Performance Requirements--Truck, Bus, and Combination of Vehicles

1998-12-23
CURRENT
J992_199812
This SAE Recommended Practice presents performance requirements for the brake systems of motor vehicles intended for roadway use and falling into the following classifications: Light trucks and buses: 6001-10 000 lb (2700-4500 kg) gvw; Truck and bus: Over 10 000 lb (4500 kg) gvw; combination of vehicles towing vehicles over 10 000 lb (4500 kg) gvw. Acceptable performance requirements are based on data obtained from applicable sections of SAE J786a (March, 1978). The purpose of this recommended practice is to establish the minimum brake system performance requirements with regard to: 3.1 Stopping ability--of cold brakes, as affected by vehicle speed. 3.2 Stopping ability--of hot brakes, as affected by vehicle speed and duty cycle. 3.3 Pedal force (air pressure) requirements--maximum allowable. 3.4 Brake stability. 3.5 stopping ability and recovery of wet brakes. 3.6 Stopping ability of emergency brake system. 3.7 Brake effectiveness distribution for vehicles in combination.

This SAE Recommended Practice applies to floodlamp, headlamp, and general service lamp units intended for use on off-road self-propelled work machines classified as construction, general purpose industrial and forestry machines, as noted in SAE J1116. Construction and industrial machinery is normally operated off highways, therefore, this document is not intended to be used as a basis for regulations by those having authority over motor vehicles used on public highways. Other performance and dimensional information is contained in SAE J572 and J760.

A Tilt Table Procedure for Measuring the Static Rollover Threshold for Heavy Trucks

1998-12-01
HISTORICAL
J2180_199812
The test procedure applies to roll coupled units such as straight trucks, tractor semitrailers, full trailers, B-trains, etc. The test is aimed at evaluating the level of lateral acceleration required to rollover a vehicle or a roll-coupled unit of a vehicle in a steady turning situation. Transient, vibratory, or dynamic rollover situations are not simulated by this test. Furthermore, the accuracy of the test decreases as the tilt angle increases, although this is a small effect at the levels of tilt angle used in testing heavy trucks. The test accuracy is accepted for vehicles that will rollover at lateral acceleration levels below 0.5 g corresponding to a tilt table angle of less than approximately 27 degrees. Even so, the results for heavy trucks with rollover thresholds greater than 0.5 g could be used for comparing their relative static roll stability.

Steady-State Circular Test Procedure for Trucks and Buses

1998-12-01
HISTORICAL
J2181_199812
This test procedure is used to determine the steady-state directional control response of vehicles by measuring steady-state cornering behavior. Due to the wide range of operational conditions to which a vehicle can be subjected, the results of this testing do not provide a complete description of a vehicle's total dynamic behavior; in particular, the procedure does not test the vehicle's response during transient maneuvers. To fully assess a vehicle's total dynamic behavior, it would be necessary to conduct other test procedures in order to evaluate the vehicle's performance as a whole. The extent of instrumentation and the required accuracy of the measurement will be dependent on the goals of the personnel conducting the test. If it is desired simply to determine the general performance characteristics of a vehicle, then this test can be conducted with minimal instrumentation and test item preparation.

HISTORICAL
J1521_199812
This SAE Recommended Practice describes two-dimensional, 95th percentile truck driver, side view, seated shin-knee contours for both the accelerator operating leg and the clutch operating leg for horizontally adjustable seats (see Figure 1). There is one contour for the clutch shin-knee and one contour for the accelerator shin-knee. There are three locating equations for each curve to accommodate male-to-female ratios of 50:50, 75:25, and 90:10 to 95:5.

Accommodation Tool Reference Point

1998-12-01
HISTORICAL
J1516_199812
Reference lines have been developed to which driver workspace accomodation tools can be located in vehicle space. The lines describe horizontal reference point locations as a function of vehicle H-point height (H30). One reference line has been established for use in vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405 and 450 mm, respectively. (Class A Vehicles) This point can be used to reference appropriate workspace tools to accommodate a driver population with a male-to-female ratio of one-to-one. Separate reference lines have been established for use in vehicles with H-point heights (H30) between 405 and 530 mm and steering wheel diameters (W9) between 450 and 560 mm with treadle type pedals. (Class B Vehicles) See Figure 1. Three lines are available for use in Class B vehicles depending on the percentages of males and females in the population the designer wishes to accommodate.

Driver Selected Seat Position

HISTORICAL
J1517_199812
A driver selected seat position tool has been developed to describe where certain percentages of drivers position horizontally adjustable seats in various workspace arrangements. The tool consists of series of equations that describe horizontal H-point locations as a function of vehicle H-point height (H30). One series of equations have been established for use in vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405 mm and 450 mm, respectively (Class A Vehicles). This class of vehicles includes passenger cars, vans, and light trucks. The lines describe the 2.5th, 5th, 10th, 50th, 90th, 95th, and 97.5th percentile accommodation levels expressed as H-point location for a driver population with a male-to-female ratio of 1:1.

CURRENT
J690_199811
[In the report of the SAE Motor Truck Rating Committee on Ability Ratings published in the January 1940 issue of the SAE Journal, it was recommended that pounds per certified net brake horsepower delivered to the clutch or its equivalent be used as the index of the potential ability of a motor truck or combination. This report defined the term "certified net brake horsepower" in detail and recommended that certain data be provided to support the certification. The accompanying forms provide a method for the presentation of the data specified.]

Minimum Requirements for Wheel-Slip Brake-Control System Malfunction Signals

1998-11-02
CURRENT
J1230_199811
It is recognized that a malfunction in any one of the specified areas can degrade intended performance, but that levels of malfunction or combinations thereof must be considered by the vehicle designer in determining the point at which a failure indication is warranted. Consequently, the minimum reaction recommended by this document consists of making available a malfunction signal. This SAE Recommended Practice establishes a uniform minimum set of functional areas to be monitored in the process of detecting malfunctions in discrete wheel-slip brake-control systems for motor vehicles, and establishes a minimum reaction to those detected malfunctions.
