Speed Control Systems

CHRYSTAL SPEED CONTROL SYSTEM

The speed control system used on Chrysler Corporation cars is electrically actuated and vacuum operated. A slide switch mounted on the turn signal lever has three positions: OFF, ON and RESUME SPEED. A SET SPEED button is located in the end of the lever.

To disengage the speed control system, the driver makes a light or normal brake application. This disengages the control unit without erasing the speed memory. If the driver moves the slide switch to OFF, or turns off the ignition switch, the system is disengaged and the speed memory is erased.

The RESUME position of the slide switch is used after the driver has applied the brake pedal. As mentioned, braking disengages the control unit without erasing the speed memory. Pressing the RESUME button, then, allows the vehicle to return to the previously memorized speed.

To increase the designated speed, the driver accelerates the vehicle to the higher rate of speed, then he momentarily depresses and releases the SPEED SET button. Or, if he wants to increase the rate of speed by small degrees, he can tap the SPEED SET button while the speed control unit is engaged and vehicle speed will rise slightly per tap.

To decrease the designated speed, the driver taps the brake pedal lightly to disengage the speed control system. When the vehicle decelerates to the new designated speed, he depresses and releases the SPEED SET button until the desired lower speed reached. Then, he releases the SPEED SET button, and the speed control system takes over at that speed.

As with other speed control systems, Chrysler’s system permits the driver to accelerate at any time. When the need for greater speed is no longer necessary, the driver releases the accelerator and the vehicle returns to the previous setting.
