The cruise control system uses a cruise control module
in order to obtain and hold any desired vehicle cruise speed above a minimum
speed of 40 km/h (25 mph).
The following 2 components within the module help achieve this
function:
• | An electronic controller that performs the following functions: |
- | Monitors the vehicle speed. |
- | Monitors the turn signal and the multifunction switch inputs. |
- | Monitors the cruise control release and the brake switch inputs. |
- | Operates the electric stepper motor. |
• | A stepper motor which moves an internal band (linked to the throttle
lever via the cruise control cable) in response to the controller in order
to maintain the desired cruise speed. |
Cruise Control Cable
The cruise control cable is adjustable and provides a physical connection
between the following components:
• | The cruise control module |
• | The engine throttle lever |
Vehicle Speed Sensor
The vehicle speed sensor (VSS) is mounted to the automatic transaxle.
The VSS provides a low voltage alternating current (AC) signal to the powertrain
control module (PCM). The PCM converts the AC signal to a pulse width
modulated direct current (DC) signal. The DC signal is sent to the cruise
control module at a rate of 4,000 pulses per mile.
Cruise Control Release Switch and Stop Lamp Switch
The cruise control release switch and the stop lamp switch disengage
the cruise control system. A cruise control release switch and a stop lamp
switch are mounted on the brake pedal bracket. The switches disengage
the system electrically when the brake pedal is pressed.
