Abstract

The invention provides a control switch device of an automobile constant-speed cruise system, belonging to the field of the automobile constant-speed cruise system. The control switch device is similar to the prior control switch device and is characterized in that a setting / decelerating key and a restoring / accelerating key are pressure sensors or displacement sensors and are connected with an electronic control unit (ECU) of the automobile constant-speed cruise system, wherein the (ECU) comprises an analogue-digital converter (A / D converter); the displacement strokes of the displacement sensors are additionally provided with springs which have automatic resetting functions; under the non-constant speed cruise state, the setting / decelerating key and the restoring / accelerating key have the functions of setting the speed of the automobile, starting the constant-speed cruise and restoring the automobile to the original speed after starting the constant-speed cruise, and under the constant-speed cruise state, the setting / decelerating key and the restoring / accelerating key have the functions of flexibly accelerating and decelerating the set speed of the automobile at random without being limited by the low speed and the road so as to effectively improve the utilization rate of the automobile constant-speed cruise system; if the setting / decelerating key and the restoring / accelerating key are pressed for a longer time, the set speed of the automobile can be accelerated and decelerated more, or the set speed of the automobile can be accelerated and decelerated less; and if the setting / decelerating key and the restoring / accelerating key are pressed under more force, the efficiency of accelerating and decelerating the set speed of the automobile can be higher, or the efficiency of accelerating and decelerating the set speed of the automobile can be lower.

Description

(1) Technical field:

[0001] The invention relates to the field of cruise control systems for automobiles. (two) background technology:

[0002] With the development of the automobile industry and the improvement of people's living standards, the number of automobiles has increased continuously, and the number of people who have obtained the qualifications for automobile driving has also increased. However, the number of major traffic casualties has also increased.

[0003] Although the car safety devices in the market are constantly emerging and improving, and the degree of automation is constantly improving, such as seat belts, safety air bags, ABS anti-lock braking systems, cruise control systems and intelligent car collision avoidance systems. But for a long time, traffic accidents cannot be completely eliminated. Among them, the traffic accidents caused by the driver's inability to effectively brake in time or even step on the accelerator by mistake account for a very h...
