Embodiment Construction

[0037]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0038] Aiming at the social problem of accidents and disasters caused by overspeeding vehicles, one way is to adopt the cable accelerator car speed limiter controlled by the host program, with intelligent chip control, high speed limit accuracy, stable and reliable performance, and no major impact Accelerator start does not affect the power torque, but only limits the maximum speed, speed limit, ...

Abstract

The invention relates to a method and a device for limiting the speed of a car. The method comprises the following steps: acquiring the real-time running speed; judging whether the real-time running speed is higher than the preset maximum running speed of the car or not; when the real-time running speed is higher than the preset maximum running speed of the car, sending a speed limiting signal to a restrictor to instruct the restrictor to reduce the air inflow of an engine cylinder of the car. When the running speed of the car exceeds the preset maximum running speed, the speed of the car can be slowed down to the preset speed automatically, so that the car running safety is ensured, and the problem of overspeed running of the car is solved.

Description

technical field [0001] The present disclosure relates to the field of vehicle control, in particular to a method and device for limiting the speed of a vehicle. Background technique [0002] Accidents caused by vehicle speeding are very thought-provoking, especially school buses, coach cars, fuel tank trucks with speed limits, mixer trucks, and internal transport vehicles in factories and mines all require a certain speed limit. Especially the cable accelerator vehicle is very prone to overspeed due to excessive oil delivery, which leads to tragedy. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides a method and device for limiting the speed of vehicles. It is realized that when the vehicle exceeds the preset maximum driving speed, the vehicle can slow down by itself. [0004] According to the first aspect of an embodiment of the present disclosure, a method for limiting the speed of a ve...
