Abstract

A control system is applied to a vehicle cruise device which is installed in a vehicle driven by an internal-combustion engine that has a speed control mechanism to control the vehicle speed. The control system includes a traveling signal input end, a command input end, a memory, a processor, and a control signal output end. The traveling signal input end is used for inputting the vehicle traveling signal into the control system. The command input end is connected to the command module for receiving the control command from the driver. The memory is used for storing the setting parameters of the control system. The processor is used for generating a control signal according to the control command, traveling signal, and setting parameters. The control signal output end is used for outputting the control signal generated by the processor, thereby controlling the drive mechanism so as to control the vehicle speed.

Claims

1. A control system of a vehicle cruise device, the vehicle cruise device being installed in a vehicle driven by an internal-combustion engine that has a speed control mechanism to control the vehicle speed, and the vehicle cruise device including a drive mechanism controllably connected to the speed control mechanism, a command module to operate the cruise control device by a driver, and the control system for receiving the command from the driver and thereby controlling the drive mechanism so as to control the vehicle speed, the control system comprising:

a traveling signal input end for inputting the vehicle traveling signal into the control system;

a command input end connected to the command module for receiving the control command from the driver;

a memory for storing the setting parameters of the control system;

a processor for generating a control signal according to the control command, traveling signal, and setting parameters; and

a control signal output end for outputting the control signal generated by the processor and thereby controlling the drive mechanism so as to control the vehicle speed.

2. The control system of the vehicle cruise device as claimed in claim 1, wherein the memory is a Non-Volatile Random Access Memory (NVRAM).

3. The control system of the vehicle cruise device as claimed in claim 2, wherein the memory is an Electrically Erasable Programmable Read-Only Memory (EEPROM).

4. The control system of the vehicle cruise device as claimed in claim 2, wherein the memory is a Flash Memory.

5. The control system of the vehicle cruise device as claimed in claim 1, wherein the parameters stored within the memory are those selected from the group consisting of the parameters of pulses per miles (PPM), acceleration pulses at initialization (INIT), over servo loop gain, and the ac/de-celeration pulses transmitted to a servo actuator after completing the acceleration or deceleration function.

6. The control system of the vehicle cruise device as claimed in claim 1, wherein the parameters stored within the memory can be set by the driver via the command module.

7. The control system of the vehicle cruise device as claimed in claim 1, wherein the control system can store at least three predetermined speeds.

8. The control system of the vehicle cruise device as claimed in claim 1, wherein the control system has a transfer program so that the control system can be applied to various command modules.

9. The control system of the vehicle cruise device as claimed in claim 1, wherein the control system further includes an indicator to indicate the operating conditions of the control system.

10. The control system of the vehicle cruise device as claimed in claim 9, wherein the indicator includes a Light Emitting Diode (LED).

11. The control system of the cruise control device as claimed in claim 9, wherein the indicator includes a buzzer.
