Description

Rollover prevention device due to the tilt of a large vehicle

The present invention relates to an overturn accident prevention device due to the tilt of a large vehicle, and in detail, to prevent the case of overturning due to a large inclination caused by the load during steep inclination and rapid cornering, the vehicle by the sensor The present invention relates to a rollover accident prevention device caused by the tilt of a large vehicle that calculates the pressure difference between the shock absorber and the shock absorber to automatically operate the impact machine to correct the vehicle tilt to prevent the rollover accident.

In general, a large truck or bus has a long body, a large load, and a large loading space, so that when the load is not constantly loaded, it is forced to run on an unstable inclined slope. In this case, it is installed to be able to run to a certain degree even if it is severely inclined by the load of the vehicle body and the load.

However, even in the case of the large vehicle in the above case, when the inclination is more than a certain angle and the traveling speed is excessive, the accident case that naturally overturns is a phenomenon that can be seen in the vicinity without difficulty.

That is, in the case of a conventional large vehicle, there is a problem that it is impossible to avoid the case of overturning according to the traveling speed when the steep slope and the rapid cornering and the load are unstable and inclined at a predetermined angle or more.

Accordingly, the present invention has been made in order to solve the problems described above, by detecting and calculating the degree of tilt of the body of a large vehicle to detect the angle of inclination of more than 40 ° to correct and automatically adjust the tilt of the body of the vehicle The aim is to provide a device that can prevent the overturning of people.

Accordingly, in the present invention, a tilt detection sensor for measuring the degree of tilt of the vehicle body and a shock absorber pressure sensor for detecting the pressure state of each shock absorber are inputted to the ECU to detect a state in which the vehicle body is inclined at 40 ° or more. When the sensing signal is applied to the solenoid valve to correct this, the impactor is automatically operated to correct the degree of tilt of the vehicle body to a certain degree so that the vehicle can be automatically controlled so as not to overturn.

Referring to the drawings illustrating the configuration of the present invention for achieving the above object is as follows.

An inclination sensor (90) is fixedly installed on the vehicle body to detect the inclination of the vehicle body, and each shock absorber includes a pull-up pressure sensor (92, 93, 94, 95) for detecting the pressure state of the shock absorber. And, the detection signal of each sensor (90, 92, 93, 94, 95) is input to the ECU 80, the ECU 80 calculates the tilt and inclination state of the vehicle by analyzing the input signal When the calculated result exceeds 40 °, it is possible to output a control signal for reducing the inclination, and the impactor 10 for adjusting the pressure state of the shock absorber is provided on the underside 50 of the vehicle body. It is installed on the left and right sides of the vehicle body, and the impactor 10 has a built-in impact load body 30 whose position is changed by the charged high pressure gas 32, and the impact load body 30 is the high pressure gas ( 32) is discharged to generate energy by falling down, the impactor 10 The solenoid valves S / V1 and S / V2 controlled to discharge the high pressure gas 32 are installed, and the solenoid valves S / V1 and S / V2 are connected to the control signal output from the ECU 80. The control signal output from the ECU 80 is amplified through the amplifying transistors TR, TR1, and TR2, and then a signal is applied to the relays RY, RY1, and RY2 so that the relays RY and RY1 are controlled. And RY2 allow the solenoid valves S / V1 and S / V2 to be directly controlled, and the controlled solenoid valves S / V1 and S / V2 are gas stored at high pressure in the paddle 10. It is configured to be discharged at a time so that the energy of the impact load body 30 can be delivered to the shock absorber.

Actions and effects on the configuration of the present invention described above are as follows.

The inclination sensor 90 installed in the vehicle body detects the inclination state of the vehicle and inputs a signal to the ECU 80, and the shock absorber pressure detection sensor 92,93, which detects the pressure state for each shock absorber of the vehicle, 94 and 95 detect the pressure state of the shock absorber and input a detection signal to the ECU 80. The ECU 80 calculates the tilt of the vehicle body and the pressure state of the shock absorber by analyzing the input signal. When the calculated result exceeds 40 ° of inclination, a control signal is output to control the shock pad 10, and the output control signal is amplified by the amplifying transistors TR, TR1, and TR2. After controlling the corresponding relays (RY, RY1, RY2) to control the impactor 10, the relay directly controls the solenoid valves (S / V1, S / V2) by the gas discharged by the impact load ( 30) The energy of the body due to the falling energy It acts to allow the degree to be corrected.

As described above, a large vehicle using the apparatus of the present invention has an advantage that the tilt of the vehicle body is automatically corrected by the impactor when the inclination of the vehicle body exceeds 40 ° during rapid ramping and cornering, thereby preventing overturning of the vehicle.
