Problems solved by technology

[0002] In the prior art, the known technology is that the driver directly controls the brake device to brake or prompts the driver to brake to achieve the purpose of speed limit. If the driver fails to step on the brake in time due to lack of concentration or other objective reasons, it may cause accident happened

Embodiment Construction

[0025] Attached below figure 1 , attached figure 2 The present invention will be further described.

[0026] The meter control module 6 is connected to the vehicle body control module 3 through the CAN bus, and the vehicle speed limit value is stored therein; the vehicle speed sensor 1 is connected to the instrument control module 6, which processes the vehicle speed sensor signal and calculates the current vehicle speed; the engine speed sensor 2 , connected to the instrument control module 6, which processes the engine speed sensor signal and calculates the current engine speed and sends it to the body control module 3; The valve 7 is connected to the air source device 8; when the speed limit is required, the vehicle body control module 3 controls the action of the solenoid valve 7, so that the engine oil cut-off device (9) is connected to the air source device (8). The engine stops oil supply, and the maximum speed limit system hardware is realized through the engine oil...

Abstract

A vehicle speed limit control device and a control method thereof, comprising: an instrument control module connected to a vehicle body control module through a CAN bus, in which a vehicle speed limit value is stored; a vehicle speed sensor connected to the instrument control module, which processes the vehicle speed sensor signal and calculate the current vehicle speed; the engine speed sensor is connected to the instrument control module, which processes the signal of the engine speed sensor and calculates the current engine speed and sends it to the body control module; and the solenoid valve, whose control terminal is connected to the body control The oil device is connected to the air source device through a solenoid valve. The hardware of the maximum speed limit system is realized through the engine oil stop device, and the vehicle does not need to add any devices, and the advantage is that the vehicle has no cost pressure. If you continue to step on the accelerator pedal when the vehicle speed is limited, the engine will not continue to inject fuel, and the fuel economy is good.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a vehicle speed limit control device and a control method thereof. Background technique [0002] In the prior art, the known technology is that the driver directly controls the brake device to brake or prompts the driver to brake to achieve the purpose of speed limit. If the driver fails to step on the brake in time due to lack of concentration or other objective reasons, it may cause Accidents happen. At present, various countries have restrictions and requirements on the speed of vehicles according to the characteristics of different regions. For example, in most sections of highways such as provincial roads and national highways in my country, the speed limit for small passenger cars is 120km / h, and the speed limit for other motor vehicles is 100km / h. h. At present, the safety technical requirements for large passenger and freight vehicles in my country ...
