CRSD-7000

Chassis Roll Stand-Alone Driver's Aid

Able to operate as a stand-alone system or in conjunction with VETS-7000NT for full emissions-testing capability, CRSD-7000 guides a driver through test cycles by graphically displaying:

Scheduled speed

Actual speed

Shift points

Tolerance for speed deviation

The system interfaces to any dynamometer by accepting analog or pulsed input signals for speed. Other analog and digital signals allow:

Initiation of user-defined events.

Charting of scheduled and actual speed on a recorder.

Data acquisition from an optional weather station and vehicle signal box.

Users can configure the driver's display by specifying display colors along with data for both alphanumeric and graphic-meter displays. Flexible screen layouts include:

Full-screen driver's trace - entire screen is filled with driver's trace.

Partial-screen trace - part of the screen is saved for user-selectable displays.

As a full-function stand-alone system, CRSD-7000:

Includes a test editor for creating and modifying driver's traces, shift schedules, and event files.

Saves 10 Hz data in test-result files on disk.

Replays test cycles using saved data.

Reports test results using Excel spreadsheet (provided by customer).

A LAN interface allows full control by a Host system such as VETS-7000NT.

Features

Basic test schedules - target speed patterns - meet worldwide statutory regulations for emission and fuel-consumption tests.
Easy-to-configure screen can display:
- Test data - error time, accumulated distance, actual speed, time into the test, time into the phase, remaining test time
- Weather station data - barometric pressure and both dew-point and dry-bulb temperatures
- Engine data - rpm and manifold vacuum
- Other user-defined signals
Meter windows provide graphic display of selected analog signals.
Configuration editor allows selection of drive-speed marker, display colors, and speed-axis orientation so that zero can appear either on the left or right.
Test editor makes it easy to edit and create vehicle tests using tables and graphics.
Coast-down timer measures time between user-defined fixed-speed intervals.
Replay function makes it easy to compare differences between scheduled and actual speed. Users can "fast-forward" to specific points in the test.
WindowsNT operating system (OS) provides a familiar operating environment.
Choice of language - Japanese, English, French or German -- can be selected during specification.
Color LCD (1,024 x 768) provides high-resolution display. Alternative monitors and displays can be supported by the PC (optional).
Wireless (infrared) driver's pendant allows easy test setup while sitting in the test vehicle.
More than 100 CRSD-7000 systems are installed and operational around the world.
