Overview of vehicle testing function
A wide variety of test functions are available to support various vehicle tests.
You can display and save the results calculated by the formula regulated by the law. In addition to time-series data, it can be saved in report format.
Basic Test Mode (Standard)
Measures the velocity, distance and elapsed time from the start to the end of measurement.
Periodic Measuring Test
Measures the following items from the start (GATE ON) to the end (GATE OFF) of measurement: maximum horizontal
velocity, minimum horizontal velocity, average horizontal velocity, horizontal distance traveled,
elapsed time, etc.
Acceleration Test
| Required options | Standalone Test Mode PC Test Mode |
LC-0827 LC-0831 |
Hardware Acceleration Test function Acceleration/Deceleration Test function |
Start Acceleration
Measures the velocity, the distance traveled, the elapsed time and the sectional acceleration at every specified step from starting measurement (zero km/h) until the vehicle reaches the speed of 100 km/h*1 or the distance of 400/1000 m*2.
*1 Velocity can be set arbitrarily.
*2 Distance can be set arbitrarily.
Passing Acceleration Test
While accelerating from a normal driving state, start testing at the point where the vehicle reaches the specified velocity or crosses the white line, and continue to accelerate.
Measures the time it takes for the vehicle to reach a specified velocity or distance.
Brake Test

LC-0828N LC-0831 |
Hardware Acceleration Test function Acceleration/Deceleration Test function |
MFDD
A brake test mode applicable to the brake efficiency evaluation standard, MFDD (mean fully developed deceleration).
Measure braking distance, braking time, MFDD, etc. from the start of application of the brake until the vehicle stops.
ABS/Wet grip
Measures the velocity/ travel distance (braking distance)/elapsed time (braking time)/sectional deceleration at each specified step from the start of application of the brake until the vehicle stops. ABS calculates the maximum deceleration (Z), wet grip calculates average deceleration (AD).
Fade Recovery Test (Made to order)
Evaluates the brake performance at high temperature by repeating Brake test. A MFDD (mean fully developed deceleration) is calculated for each deceleration from brake start speed v1 to brake end speed v2. The measurement is eventually terminated when the vehicle reaches the measurement end speed by decelerating from the measurement start speed. The braking distance and MFDD are calculated.
Coasting test
| Required options | Standalone Test Mode PC Test Mode |
LC-0829 LC-0831 |
Hardware Coastdown Test function Acceleration/Deceleration Test function |
Measures coasting ability of vehicles, such as coefficient (C/D factor), sectional average velocity and distance traveled and elapsed time from when the accelerator pedal is released (or neutral is selected) and the speed drops below the speed at the start of measurement (or the START button is pressed) to when the speed reaches the end of the measurement (or when the STOP button is pressed).
Fuel consumption test
| Required options | PC Test Mode | LC-0832 | Fuel Consumption Test function |
Constant-Speed Fuel Consumption Test
Measures the fuel economy of a vehicle traveling at a constant speed with constant accelerator application on a horizontal, straight-line road. The test can acquire data such as travel distance, elapsed time, mean speed, cumulative fuel consumption and cumulative fuel economy. Measurement result data is acquired for each distance step or time step after the start of measurement.
Pattern-Mode Fuel Consumption Test
Measures values for each of multiple intervals for a varied travel pattern: distance, time, interval mean velocity,
interval fuel flow rate, interval fuel economy, mean velocity, fuel flow rate and fuel economy.
For example, executing a pattern-mode fuel consumption test with one circuit of the test course set as one interval enables to acquire fuel economy and other measurement results for individual circuits or the totals for all the circuits.
Orbit analysis
| Required options | PC Test Mode | LC-0833 | Orbit Display function |
Traveling Trace Measurement
Measures the vehicle's traveling trace between the start and end of measurement, and graphs the measured results as a relative traveling trace.
*The LC-8220 GPS vector speedometer is required to display vehicle heading.
Drift measurement
Measures the drift amount between the start and end of measurement.
Minimum Rotation Radius Measurement
Measures the minimum rotation radius of a vehicle.
