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, method and vehicle, which are applied to the pressure control of PTU and / or RDU systems. The device includes a pressure detection module for measuring the pressure information of the PTU and / or RDU system in real time; the pressure detection module includes Vent plug and load cell, the vent plug is connected with PTU and / or RDU, the vent plug includes a vent slot, the load cell is set in the vent slot, and the load cell is used to measure the pressure information in the vent slot in real time; the first judgment A module for judging whether the pressure information exceeds the first threshold; a reminder module for sending the first warning message to the driver when the pressure information exceeds the first threshold; a second judging module for judging whether the pressure information exceeds the second Threshold; the vehicle control module is used to control the PTU and / or RDU to stop working when the pressure information exceeds the second threshold, and to send a second warning message to the driver, which improves the function of system pressure monitoring, thereby improving the PTU (or RDU) protection and security.

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...
