Embodiment 1

[0057] A remote speed limiting method for commercial vehicles, the speed limiting method comprising the following steps:

[0058] Step 1: The remote platform issues a speed limit command, the remote platform first selects the execution conditions of the speed limit command, a is executed at the next ON gear, b is executed when the speed limit condition is met, or c is executed immediately, and then the speed limit is set according to the selected execution condition parameter:

[0059] If you choose a next ON gear to execute, set the speed limit vehicle speed N km / h, and the value range of N is 20–80;

[0060] If you choose b to meet the speed limit condition, then select the speed limit condition: at least one of vehicle speed limit, engine speed limit or engine torque limit, and then fill in the parameters of the speed limit condition:

[0061] The speed limit is M km / h, and the value of M ranges from 20 to 80.

[0062] The speed limit engine speed J rev / min, the value ran...

Embodiment 2

[0075] Example 2 is basically the same as Example 1, except that:

[0076] The third step: when the speed limit is executed, the bodywork controller will monitor in real time whether other control units on the CAN bus are requesting engine speed / torque control, in order not to affect the automatic transmission, retarder, etc. The brake-related key controller effectively controls the engine. The bodywork controller will only issue the corresponding speed limit control command when no other control unit is detected to request engine speed / torque control.

Embodiment 3

[0078] Embodiment 3 is basically the same as Embodiment 1, except that:

[0079] The first step: the default value of the speed limit parameter N in the speed limit command issued by the remote platform is 20, the default value of the speed limit parameter M is 20, the default value of the speed limit parameter J is 1000, and the default value of the speed limit parameter K is 30, and the default value of the speed limit parameter G is 20.

Abstract

A remote speed limit method for a commercial vehicle, the speed limit method comprising: the first step is to send a speed limit command from a remote platform, set the execution conditions of the speed limit command, and set the speed limit parameter; the second step is to receive the command, perform safety check , the vehicle performs safety verification after receiving the remote command, and executes the next step after passing the safety verification; the third step is to implement speed limit, and the bodywork controller executes speed limit according to the speed limit command; this design is aimed at remote speed limit for commercial vehicles, not only The remote control of the vehicle is strengthened, and the speed limit scheme is safe and reliable.

Description

technical field [0001] The invention relates to a speed limiting method for commercial vehicles, in particular to a remote speed limiting method for commercial vehicles, which is particularly suitable for strengthening the remote management of vehicles and improving the safety of remote speed limiting of vehicles. Background technique [0002] In recent years, it has become quite common for people to take out a loan to buy a car. However, for the automobile enterprise finance company or financial institution that issues the vehicle loan, how to restrain the vehicle purchaser from paying the vehicle loan on time and the amount after the vehicle is sold is a relatively critical issue. The most common method at present is to install a GPS positioning device on the vehicle, and dispatch a special person to collect the expenses or seize the vehicle on the spot after determining the location of the vehicle that still fails to perform the repayment obligation. With the rapid promo...
