Embodiment Construction

[0029] The invention provides a vehicle speed limit control system and control method, which are used to solve the problem of troublesome operation when setting the vehicle speed limit value in the prior art.

[0030] To achieve the above object, the technical solution provided by the invention is:

[0031] A vehicle speed limit control method, comprising the steps of:

[0032] Judging whether the speed limit setting signal is received, if it is received, the current speed of the vehicle is used as the speed limit value and enters the speed limit mode;

[0033] In the speed limit mode, detect the current driving speed of the vehicle in real time, and judge whether the difference between the current driving speed of the vehicle and the speed limit value is within the set range; if the difference between the current driving speed of the vehicle and the speed limit value is If the difference is within the set range, the vehicle is processed to reduce the driving torque.

Abstract

The invention provides a vehicle speed-limiting control system and a control method. The control method comprises the following steps: judging whether a speed-limiting setting signal is received, if so, using a current speed of a vehicle as a speed-limiting value, and entering a speed-limiting mode; under the speed-limiting mode, detecting a current driving speed of the vehicle in real time, and judging whether a difference value between the current driving speed of the vehicle and the speed-limiting value is within a setting range; and if the difference value between the current driving speedof the vehicle and the speed-limiting value is within the setting range, performing driving torque reducing treatment on the vehicle. According to a technical scheme provided by the invention, only the speed-limiting setting signal needs to be sent to the vehicle, so that the current driving speed of the vehicle can be taken by the vehicle as the speed-limiting value for limiting the speed of thevehicle; and the vehicle speed-limiting control system and the control method are not only simple and convenient in operation, but also low in cost, and simple in control logic.

Description

technical field [0001] The invention belongs to the technical field of vehicle running control, and in particular relates to a vehicle speed limit control system and control method. Background technique [0002] With the development of science and technology, the performance of automobile power system has been developed rapidly, and the average speed of vehicles on the road has also been accelerated. However, when technology brings us high-speed convenience, accidents caused by cars are also increasing, among which traffic accidents caused by speeding account for a very high proportion of the total number of accidents. Therefore, in order to ensure the safe driving of automobiles, it is necessary to limit the driving speed of vehicles. [0003] Limiting the speed of the vehicle means first setting the speed limit value of the vehicle. When the speed of the vehicle is greater than the speed limit value, the vehicle controller will send out an alarm, and at the same time cont...
