Trailer type recreational vehicle rollover interaction early warning system and rollover interaction early warning method

Abstract

The invention discloses a trailer type recreational vehicle rollover interaction early warning system and a rollover interaction early warning method. The system comprises a steering angle sensor, a control unit module, a wireless transmission module, a sensor response module, a warning light response module and a fault detection module, wherein the control unit module comprises an ECU and a recreational vehicle microprocessor, the steering angle sensor is connected with the ECU, the ECU is connected with the tractor end of the wireless transmission module, the recreational vehicle end of thewireless transmission module is connected with the sensor response module, the recreational room sensor response module, the warning light response module and the fault detection module are all connected with the recreational room microprocessor, and the output end of the fault detection module is connected with the recreational room end of the wireless transmission module. The method and the system are more applicable to the two-part separated vehicle type of trailer type recreational vehicle types, the judgement is accurate and comprehensive, for the wireless transmission signal, potential safety hazards caused by too many wires are avoided, the service life is prolonged, the early warning signal is bi-directionally conducted, and the effects of being efficient and safe are achieved.

Description

technical field [0001] The invention relates to a trailer-type car body and an automotive electronic system, in particular to a trailer-type caravan interactive warning system for roll, and belongs to the field of vehicle engineering. Background technique [0002] Trailer-trailer RVs are prone to rollovers when they change lanes and turn at high speeds when driving in a straight line. From theoretical analysis, the reasons for their instability and rollovers are summarized into two aspects: First, when the tractor is driving normally, too many lane changes cause the RVs to roll over. The yaw rate is too large to make it roll; the second is that the vehicle speed is too fast or the steering angle is too large when turning, which causes the roll angle of the RV and the height of the chassis from the ground is too large. [0003] The existing technology mainly designs an integrated wired roll warning for the whole car, detects the vehicle condition through the load sensor, and ...
