Problems solved by technology

[0007] (2) Elimination function: When the CAN (release button) is pressed, the clutch pedal, brake pedal or the shift lever is placed in the "P", "R", "N" and "1" positions to temporarily shut down the system. Immediately cancel the cruise control, but the above-mentioned adjusted speed continues to be stored;
However, the system itself also has the following defects: due to road conditions, it must be used on expressways or fully enclosed roads, and the road conditions on non-enclosed roads are complicated, such as on national highways, the impact of insufficient power for some small motor vehicles, pedestrian crossing in urban streets And the intersection of traffic lights will cause obstacles to cruising cars, so the manufacturer sets the system to automatically release the function to limit the use when the speed is lower than 60 kilometers per hour, so the usage rate is not high, and the safety hazards of not being able to timely and effectively emergency brake or even stepping on the accelerator pedal by mistake are still there. always haunt us
Moreover, the operation of the operation switch is complex and requires the use of both hands and feet. At this time, even if the system does not have the automatic release function of 60 kilometers per hour to limit the use, it cannot control the speed of the vehicle as flexibly as the accelerator pedal, and the constant speed cruise has no practical significance. more troublesome
When using the recovery function, if the set cruising speed is too high compared with the current traffic conditions, or even the driver has forgotten the original set speed, there will be dangers
The reasons for these defects in the system are: the position design of the control switch SET / - (setting / deceleration key) is not humanized enough, and the operation is inconvenient; the design of the control switch RES / + (recovery / acceleration key) has potential safety hazards, etc.

Embodiment approach

[0027] First make a pedal switch pad (18) as the release / set key (16), please refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 7 , Figure 8 , its shape and area are equivalent to those of the gas pedal (4), and the structure of the pedal switch pad (18) is: between the surface layer (1) and the bottom layer (3) made of rubber or polyurethane materials, a plurality of plastic The switch layer (2) composed of membrane switches (5) connected in parallel, that is, integrated manufacturing becomes on the same film, the area of ​​the switch layer (2) is slightly smaller than that of the surface layer (1) and the bottom layer (3), and the surface layer (1) is front It is made into a non-slip surface with rough uneven surface and anti-slip function. The back of the surface layer (1) is provided with slightly raised dots (9) at the contact positions corresponding to the plastic film switches (5) on the switch layer (2). ), so that when the pedal switch pad (18) is s...

Abstract

The invention relates to the field of a vehicle constant speed cruise system and provides a control switch device for the vehicle constant speed cruise system, similar to the same type of the existing device. The control switch device is characterized in that a cancelling / setting key contained is a pedal switch cushion with shape and area being roughly equal to that of an accelerator pedal, the pedal switch cushion is adhered and overlapped on the accelerator pedal by adhesive, two flexible wires are led out from the pedal switch cushion for being connected with an electronic control unit (ECU) of the constant speed cruise system; when in use, a master switch of the constant speed cruise system is turned on for initialization and stand-by; when the accelerator pedal is pedaled by the foot, the pedal switch cushion is also pedaled simultaneously and the function of constant speed cruise disappears in time; when the accelerator pedal is released, the pedal switch cushion is also released simultaneously, the speed of vehicle is set, and the function of constant speed cruise is started; as the device has simple structure, low manufacturing cost, easy installation and convenient operation, as long as the master switch of the system is turned on and other operations are same as common driving operations, the device has no low-speed limit and is applicable for any rode, thereby efficiently improving the utilization rate of the constant speed cruise system.

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...
