Embodiment 1

[0041] Since today's four-wheel-drive vehicles cannot detect the pressure information of the PTU (or RDU) system, and the system will fail when the pressure is too high, thereby increasing maintenance costs and other dangerous situations, an embodiment of this specification provides a The pressure control device is used to detect and control the pressure information of the vehicle PTU (or RDU) system in real time, so as to effectively avoid the occurrence of vehicle failures.

[0042] Specifically, such as Figures 1 to 3 As shown, the device may include: a pressure detection module (1), a first judgment module 2, a reminder module 3, a second judgment module 4 and a vehicle control module 5; wherein the pressure detection module 1 is used for real-time measurement of vehicle PTU and / or RDU system pressure information; the pressure detection module 1 includes a vent plug and a load cell 11, the vent plug is connected with the vehicle PTU and / or RDU, the vent plug includes a ve...

Abstract

The invention discloses a pressure control device and method and a vehicle, which are applied to PTU and / or RDU system pressure control, and the device comprises a pressure detection module which is used for measuring PTU and / or RDU system pressure information in real time; the pressure detection module comprises a ventilation plug and a pressure measurement element, the ventilation plug is connected with the PTU and / or the RDU, the ventilation plug comprises a ventilation groove, the pressure measurement element is arranged in the ventilation groove, and the pressure measurement element is used for measuring pressure information in the ventilation groove in real time; the first judgment module is used for judging whether the pressure information exceeds a first threshold value or not; thereminding module is used for sending first warning information to a driver when the pressure information exceeds a first threshold value; the second judgment module is used for judging whether the pressure information exceeds a second threshold value or not; and the vehicle control module is used for controlling the PTU and / or the RDU to stop working and sending second warning information to thedriver when the pressure information exceeds a second threshold value, so that the system pressure monitoring function is improved, and the protection and safety of the PTU (or the RDU) are improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a pressure control device, method and vehicle. Background technique [0002] All urban four-wheel-drive SUVs are equipped with a timely four-wheel drive system. The electronic control equipment of this type of four-wheel drive system is arranged on the torque manager, and the power take-off or transfer case at the front, that is, the Power Transfer Unit (PTU) and The rear main reducer, that is, the Rear Drive unit (RDU) has no electronic control device, but a purely mechanical structure, so there is no electronic control and detection, and it is impossible to identify the excessive pressure of the PTU (or RDU) . [0003] At present, after-sales failure modes of PTU (or RDU) include oil seal detachment, abnormal noise, etc. Correct the reason, because the internal pressure of the PTU (or RDU) exceeds the limit value, and then the oil seal falls off because the system pressure e...
