公報参照）。An air suspension that utilizes the bulk elasticity of air is used as a wheel suspension system for automobiles, and vehicle height sensors are installed in each of the front, left, and right air suspension sections, and air supply to each air suspension is controlled based on the signals from each vehicle height sensor. A vehicle height adjustment device that is equipped with a control device that controls exhaust gas independently and automatically normalizes the vehicle posture is already known (see, for example, Japanese Patent Laid-Open No. 58-112817).

である。As mentioned above, if any of the four wheel suspensions on the front, rear, left, and right wheels becomes lower or higher than the normal height (or set height) for some reason, an up signal or down signal from the vehicle height sensor of that suspension will be sent. In a vehicle height adjustment device that supplies air to the air-filled part of the suspension and discharges the air in the air-filled part to the outside to bring the vehicle height to the normal height, for example, only one wheel is placed in a side ditch, etc. The vehicle height adjustment device also operates if only one wheel runs onto a curb, etc., but in such cases, no matter how many times you try to adjust the air suspension, the vehicle It is impossible to balance the vehicle's posture, and the vehicle remains in an unstable posture. Therefore, the vehicle must continue to drive toward the vehicle height up signal or vehicle height down signal. When you return to the normal position and start running, it takes a certain amount of time (
Depending on the device, the time ranges from a few seconds to 2.6 minutes) 7
5) Because of the force, there is a large difference in height between the left and right sides, and the steering stability is extremely poor, making IF always dangerous from a safety perspective.

Air suspension solenoid pulp and exhaust pulp Lt' equipped with a vehicle height sensor that controls energization and issues a down signal, for example.
zt: Opens the air suspension solenoid pulp and solenoid pulp L for air supply and exhaust of the air suspension equipped with the vehicle height control system that is opened to discharge air from the air suspension and lower the vehicle height, or that has issued the up signal. As a result, air in the reserve tank 3 on the air suspension is supplied to raise the vehicle height, and energization of the solenoid L7 is controlled based on a signal from the pressure sensor 4.

の向上をはかり得るようになっている。Furthermore, the control device 5 is configured to receive a signal from a changeover switch 6 for changing the vehicle height from a normal vehicle height to a high vehicle height, and also to receive a vehicle speed signal from a vehicle speed sensor γ. For example, when driving on a rough road, by switching the changeover switch 6 from normal to no h, the control device 5 is activated by the signal.
The system emits air supply to each air suspension to raise the vehicle height, preventing accidents such as the vehicle body touching the ground when driving on rough roads, and also lowering the vehicle speed when driving at high speeds. Based on the signal from the sensor 7, the control device 5 issues a signal to discharge the air in the air-sealed portion of the valley air suspension to the outside, thereby lowering the height of the vehicle and improving stability at high speed.

ことも筐だ判明した。As a result of various experiments conducted by Fukuban et al. on a vehicle equipped with the vehicle height adjustment device as described above, we found that when only one of the four wheels on the front, rear, left, and right sides falls into a gutter, etc., or when only one wheel falls onto a curb. If you run over a vehicle, the vehicle height sensors of the two diagonally positioned suspensions of the four wheels, that is, A and D, or B and C, are the same type of signal (i.e., down signal or up signal). It was found that the vehicle height sensors of the other two wheels' suspensions either emitted signals of a different type from those described above or did not emit any signals at all. Then, as mentioned above, the vehicle height sensors of two wheels diagonally located emit the same type of signal, and the vehicle height sensors of the other two wheels emit a different type of signal, or they do not emit any signal at all. It was also discovered that the combination of signals from the vehicle height sensor is almost impossible under normal driving conditions, except when only one wheel falls into a ditch or runs onto a curb.
そこで本発明では、車高センサＡ、Ｂ、Ｃ。Therefore, in the present invention, vehicle height sensors A, B, and C are used.

る。Among D, if A and D both emit an up signal and B and C do not emit an up signal, if A and D both emit a down signal and B and C do not emit a down signal, then B and C If A and D both emit an up signal and A and D do not emit an up signal, and if B and C both emit a down signal and A and D do not emit an up signal, that is, they are in diagonal positions among the four wheels. If the vehicle height sensor of two wheels emits the same type of signal, and the vehicle height sensor of the other two wheels emits a different type of signal, or does not emit any signal, the vehicle height sensor of the other two wheels may have fallen into a ditch, etc., or a curb, etc. A logic circuit 51 is added to the control device 5, which determines that the air suspension is in an abnormal state and stops the air supply and exhaust operations to each air suspension.

のである。According to the present invention configured as described above, only one wheel falls into a gutter or rides on a curb, etc., and the vehicle height sensors of the two diagonally positioned wheels both emit the same type of signal, and the other two wheels If the vehicle height sensor emits a signal different from the above or does not emit a signal, these signals are transmitted to the control device 5.
When this is input, the logic circuit 51 issues a signal to the control device 5 to stop the air supply/exhaust operation to each air suspension, and no vehicle height adjustment is performed at all. Therefore, when the vehicle is returned to a flat road after that, the vehicle attitude will be maintained at the normal attitude 11 before falling into a ditch or riding on a curb, etc., without affecting the steering stability during subsequent driving. This allows you to start driving safely.
尚上記ロジック回路５１が通常時の車両姿勢制御に何ら
悪影響を及ぼさないことは言う迄もない。It goes without saying that the logic circuit 51 does not have any adverse effect on the vehicle attitude control during normal operation.

It can prevent the vehicle from becoming unbalanced when it starts running, and it is extremely effective in contributing to improving running stability.
