CRUISE CONTROL SYSTEM

DESCRIPTION

FUNCTIONS OF INDIVIDUAL SWITCHES

1. SET (Vehicle Speed Set)
When SET switch is turned "ON" and "OFF" while the vehicle is running at a speed within the range of the lowest running speed to the highest memory speed, specified in the Performance Standards, the speed is instantaneously registered in memory(memory speed) and actuator is there after regulated to maintain vehicle speed at the memory speed.

2. COAST (Self-Retardation)
When SET switch is turned "ON" while the vehicle is running at regulated speed, vehicle speed is retarded while the switch is "ON". When it is turned "OFF", the then prevailing speed is instantaneously registered in memory and actuator is regulated to maintain vehicle speed at the newly registered value.

3. RESUME (Auto Recovery)
After regulated speed run is released according to according to the conditions specified in 5.2, 5.3 and 5.4, when RESUME switch is turned "ON" during motion at a speed faster than the lowest running speed shown in 4.5, actuator is recover and maintain the memory speed set prior to release.
a. CIG. KEY. SW. OFF
b. ACC MAIN SW. OFF

4. ACCEL (Belt-Acceleration)
When RESUME switch is turned "ON" during regulated speed run, vehicle speed is increased as long as it is "ON". When the switch is turned "OFF", the then prevailing speed is registered in memory to regulate actuator to maintain that speed thereafter.

CANCELLATION
Regulated speed run shall be released when external switches are switched as following.
1. Stop lamp switch is turned "ON". (Brake pedal is depressed)
This also applies to the disconnection of the input wire.
2. Brake switch or CANCEL switch is turned "ON". (Brake pedal is depressed)
3. Inhibitor switch is turned "ON".
(Gear shift lever is in either P or N position.)
4. Ignition key switch is turned "OFF".
5. MAIN switch is turned "OFF".

AUTO CANCELLATION
Regulated speed run shall be automatically released in any of the following conditions:
1. When vehicle speed falls down below the lowest running speed. (40 Km/h)
2. When regulated speed falls below memory speed by the width of the redundant brake speed range of more.
3. When vehicle speed during resume operation falls below memory speed by width of the redundant brake speed range of more after once rising above the speed of "memory speed- 10 Km/h"
