According to the automobile cruise control device disclosed by the utility model, the main control module outputs voltage signals to control the torque of a direct-current motor; and by balancing with a moment of a spring device, the variation of a throttle percentage is realized, the travelling speed of the automobile is automatically adjusted, and the cruise control of the automobile is realized.
Description
Technical field
The utility model relates to control setup, particularly a kind of cruise control device for automobile, and this installs by Single-chip Controlling, to realize the electronic throttle aperture control of automobile fixed speed cruise.
Background technology
Along with the mankind get into 21 century, auto trade has also got into the period of a develop rapidly, and this big guy of automobile has also unloaded its mysterious veil and come into huge numbers of families.Along with the progress of science and technology, people also progressively improve the requirement of vehicle drive traveling comfort, and the constant-speed cruising device that can break away from the Das Gaspedal constraint has vast market prospect.
Traditional air throttle of car device needs artificial the going of people to trample Das Gaspedal to realize the maintenance of car speed, and this has influenced automobile single-piece driver comfort greatly.For example Chinese patent (patent No.: ZL 200710060542.8) discloses a kind of electronic air throttle control device, can realize the adjustment to throttle opening automatically according to the intention of chaufeur, but can not realize the requirement of automobile fixed speed cruise operating mode.And for example (patent No.: ZL 00112742.x) said, it adopts the mechanical type throttle-valve control to Chinese patent, can not satisfy the requirement of modern automobile to throttle-valve control high precision, high stability.
Modern automobile should satisfy the requirement of driver comfort and safety simultaneously, but therefore is starved of a kind of device of done with high accuracy automobile fixed speed cruise control.
Summary of the invention
The purpose of the utility model is, a kind of cruise control device for automobile is provided, and this device can be according to the demand of chaufeur, automatically regulating Vehicle Speed, and the cruise of realization vehicle.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of cruise control device for automobile comprises it is characterized in that the gauge panel of automobile, and the micro controller system main control module is installed in gauge panel, is connected with velocity response module, display module, control panel and throttle valve drive module on the micro controller system main control module.
Other characteristics of the utility model are following:
Described micro controller system main control module adopts Freescale MC9S12XDP512.
Described velocity response module is made up of Hall car speed sensor and signal amplification circuit.
Described display module is made up of LED LCDs and auxiliary circuit thereof.

Described throttle valve drive module is made up of DC machine and spring installation.
The cruise control device for automobile of the utility model; Through the torque of micro controller system main control module output voltage signal control DC machine,, realize the variation of throttle opening through reaching balance with spring installation moment; Automatically regulating Vehicle Speed, and the cruise of realization vehicle.
Description of drawings
Fig. 1 is the hardware configuration scheme drawing of the utility model;
Fig. 2 is the control panel structure scheme drawing;
Fig. 3 is the workflow diagram of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The specific embodiment
With reference to Fig. 1; Present embodiment provides a kind of cruise control device for automobile, comprises the gauge panel of automobile, it is characterized in that; The micro controller system main control module is installed in gauge panel, is connected with velocity response module, display module, control panel and throttle valve drive module on the micro controller system main control module.
In the present embodiment, the micro controller system main control module adopts Freescale MC9S12XDP512.
The velocity response module is made up of Hall car speed sensor and signal amplification circuit.
Display module is made up of LED LCDs and auxiliary circuit thereof.
The throttle valve drive module is made up of DC machine and spring installation.
The MC9S12XDP512 micro controller system adopts the 5V power supply, and the bus speed of 25MHZ is mainly used in Industry Control, is particularly suitable for being used on the automobile.The characteristics of this MC9S12XDP512 micro controller system are I/O and the special-purpose communication modules of enriching of Industry Control.The Flash capacity is 512KB, and communication module has SCI, SPI, IIC, CAN, J1850 etc.Its 112 pin package 91 I/O pins are arranged, 16 tunnel 10 A/D switched pins, 8 tunnel 8 PWM pins and 8 tunnel 16 TIM pins can be simplified peripheral circuit greatly.
The MC9S12XDP512 micro controller system is issued in the detection of the real-time car speed of Hall car speed sensor, and output and speed of a motor vehicle corresponding voltage signal then.
The LED display module can show current cruise speed of a motor vehicle setting value according to driver's operation.
Control panel is as shown in Figure 2.Can carry out the operating and setting speed of a motor vehicle by chaufeur, and send through the I/O of MC9S12XDP512 micro controller system oral instructions.Button "+" "-" can be realized the increase and decrease of speed 1km/h among the figure, and button among the figure "+10 " " 10 " can be realized the increase and decrease of speed setting 10km/h.
The utility model cruise control device for automobile, concrete working process starts cruise control device for automobile with reference to shown in Figure 3; Program initialization; Set the speed of a motor vehicle of cruising by chaufeur, send by the oral instructions of MC9S12XDP512 single-chip processor i/o, and show the current setting speed of a motor vehicle through LED display.The Hall car speed sensor carries out the current vehicle speed collection, passes to the MC9S12XDP512 micro controller system to speed information through serial communication and carries out data handing, if current vehicle speed equals to set then program termination of the speed of a motor vehicle; If current vehicle speed is not equal to the setting speed of a motor vehicle, then MC9S12XDP512 micro controller system output voltage signal is given DC machine, with the torque of control DC machine; Through reaching balance with spring installation moment; Realize the variation of throttle opening, the automatically regulating Vehicle Speed finally reaches the constant of the speed of a motor vehicle.
