Embodiment 1

[0036] Such as figure 1 As shown, the present invention provides a vehicle speed limit safety guarantee system, including an automatic speed limit adjustment mechanism, an emergency release speed limit mechanism, and a coupling mechanism arranged between the automatic speed limit adjustment mechanism and the emergency speed limit release mechanism.

[0037] The automatic adjustment speed limiting mechanism includes a bracket 210 that is pivotally connected to the vehicle body 100 of the vehicle, a driving device 220 arranged on the bracket 210, and a driving device 220 that is arranged on the bracket 210 and can be driven by the driving device 220 to operate on the throttle of the vehicle. The speed limit executive device 230 that telescopically shifts under the pedal 4 . Wherein, reference numeral 300 is a compartment floor, and reference numeral 400 is an accelerator connecting rod.

[0038] The emergency release speed limiting mechanism includes an operation button 510, a ...

Embodiment 2

[0043] Such as figure 2 As shown, the present invention is a vehicle speed limit safety assurance system, the system includes a vehicle ECU 1 and a safety driving device 2, and a communication module 3 is respectively arranged on the safety driving device 2 and the vehicle ECU 1, and the safety driving device 2 will receive The received speed measurement information is sent wirelessly (wired communication can also be used in other embodiments) to the vehicle ECU 1, and the vehicle ECU 1 analyzes and compares the received speed measurement information with the engine speed information obtained by the test, if the engine speed is greater than the speed limit value , the vehicle ECU outputs a control command to drive the speed limit actuator to act. If the engine speed is lower than the speed limit value and the speed measurement information sent by the safety driving device disappears, the vehicle ECU outputs a control command to drive the speed limit actuator to reset.

[0044...

Embodiment 3

[0048] Such as image 3 As shown, according to this non-limiting embodiment 3, on the basis of embodiment 2, the speed limit execution device also includes a hydraulic cylinder or cylinder 9 fixed under the accelerator pedal 4 of the vehicle, and the hydraulic cylinder or cylinder 9 cooperates with the piston rod 10 The spherical rubber head 15 at the end of the piston rod 10 is arranged under the accelerator pedal 4, and the hydraulic cylinder or cylinder 9 is connected with the electromagnetic proportional valve 11 and the oil pump or air pump 12 through the pipeline, and the electromagnetic proportional valve 11 and the oil pump or air pump 12 are also connected. It is electrically connected with the output control terminal of the vehicle ECU 1 .

[0049] The speed limiting actuator is similar in principle to the above-mentioned screw nut driving mechanism, and also has the characteristics of simple structure, high working reliability, convenient fabrication, easy loading a...

Abstract

The invention discloses a vehicle speed limit safety guarantee system, which comprises an automatic speed limit adjustment mechanism, an emergency release speed limit mechanism, and a coupling mechanism arranged between the automatic speed limit adjustment mechanism and the emergency speed limit release mechanism. The automatic adjustment speed limiting mechanism includes a support pivotally connected to the vehicle body, a driving device arranged on the support, and a telescopic shifter arranged on the support and capable of being driven by the driving device to move telescopically under the accelerator pedal of the vehicle. Speed ​​limit actuator. The emergency release speed limiting mechanism includes an operation button, a transmission rack connected to the end of the operation button, and an elastic reset element arranged between the end of the transmission rack and the vehicle body. The coupling mechanism includes a transmission gear fixed to the bracket, capable of pivoting synchronously with the bracket and meshing with the transmission rack. When the operation button is pressed, the transmission rack drives the transmission gear to rotate, and then drives the bracket to pivot, so that the automatic adjustment speed-limiting mechanism is deflected from the speed-limiting position to the non-speed-limiting position.

Description

technical field [0001] The invention relates to the technical field of vehicle automatic control, in particular to a vehicle safety guarantee system. Background technique [0002] At present, the speed limit of the vehicle is mainly realized by setting a speed limit control device composed of a speed limit switch in the driver's area. The driver needs to set the maximum speed according to the speed limit switch, and the speed limit switch transmits this signal to the ECU of the engine. Or vehicle speed limiting device to control the top speed of the vehicle. However, this control method cannot automatically limit the maximum speed of the vehicle according to the speed limit requirements of the road. If the driver misoperates or does not perform the speed limit operation, it is easy for the vehicle to overspeed, and even cause damage to passengers and drivers. [0003] As disclosed in Chinese Patent Publication No. 202518102U, a speed limiter for automobile machinery include...
