。Currently, a vehicle such as a passenger car that is commonly used is equipped with two selective reference levels, and the vehicle height is adjusted based on each selected reference level (5) A vehicle height adjustment device has been proposed. Such vehicle height adjustment devices are generally configured to adjust the vehicle height at a low reference level when driving on normal roads, and at a high reference level when driving on rough terrain. In addition, with such a vehicle height adjustment device having two reference levels, the driver must manually decide whether to adjust the vehicle height at a higher reference level or a lower reference level based on his/her own judgment. Vehicle height adjustment at each of the above reference levels means that the vehicle height is lowered or higher than the reference level due to an increase or decrease in the load on the vehicle. It means to operate so as to bring it to the appropriate position which is the reference level.

る。However, the following problems arise in the vehicle height adjustment device having the above-mentioned configuration. In other words, if the driver starts driving at a high speed on a road where high speeds are possible after driving at a low speed with a high standard vehicle height on a rough road or uneven ground, the driver may adjust the vehicle height using the vehicle height adjustment device. If the position is not switched from the high reference level to the low reference level, the vehicle height will remain high, which raises the problem that the vehicle height will not be at the appropriate position when traveling at high speeds (which is inconvenient).

のである。The above-mentioned sensors 3.4 are arranged at approximately the same appropriate locations on the vehicle, and are each independently set to detect the vehicle height condition based on a reference level. It has functions such as detecting the relative positional relationship with the lower part of the spring and measuring the distance between the spring and the road surface.
A luer constant ()) signal is output by a comparison mechanism with a reference level related to each vehicle height set in advance. Specifically, when the vehicle height is at the reference level, a signal is output that makes the vehicle height adjustment device inactive, and when the vehicle height is not at the reference level, the signal is output to activate the vehicle height adjustment device to bring the vehicle height to the reference level. A signal is output to set the state. The changeover circuit 2 mainly consists of a changeover switch 2a, and is usually a manual switch 7 installed near the driver's seat and operated by the driver or the like.
Based on this, the switching designation circuit 8 operates to transmit one of the output signals of the sensor 3.4 to the signal processing circuit 1.

われる。According to the configuration described above, when the vehicle height is selected and is at either the high or low reference level, the vehicle height adjustment device is in the inactive state, while when the vehicle height is at a level other than the reference level, the vehicle height adjustment device is in the active state. The vehicle height is adjusted in a timely manner, and the vehicle height is adjusted to an appropriate position at the reference level. Furthermore, the relationship between the output signals of sensors 3 and 4 is such that when one sensor detects a state in which the vehicle height is at the reference level, the other sensor detects all states in which the vehicle height is outside the reference level. Therefore, when the vehicle height is adjusted to the appropriate position based on the output signal of either sensor 3 or 4, the manual switch 7 and the switching instruction circuit 8 When switching the connection relationship to another sensor, the vehicle height is adjusted so that the vehicle height is at an appropriate position with respect to the reference level of the other sensor.Therefore, in this case, when adjusting the vehicle height, the connection from sensor 4 to sensor 3 must be changed. When switched, the vehicle height increases and sensor 3
If you switch from 4 to 4, the vehicle height will be adjusted to lower the vehicle height.

数が車速に比例し１こパルス列信号が出力される。The vehicle speed sensor 9 includes a switch 9a that turns on and off in response to the rotation of the wheels of the vehicle, a resistor R, and an anode +V of a gold battery.
Since the switch 9a is configured so that the number of on/off times is proportional to the number of rotations of the wheel, the frequency of the switch 9a is proportional to the vehicle speed as a voltage generated at the zero point from the vehicle speed sensor 9. A single pulse train signal is output.

The circuit mA consisting of 3 is a circuit that has a delay effect only in the deceleration direction. Specifically, when the voltage at point p is higher than the voltage at point q, the voltage at point q is immediately changed to the voltage at point p via diode D1. However, when the voltage at point p becomes smaller than the voltage at point q, capacitor CI
The system is configured to operate so that the voltage at point q becomes relatively small due to the discharging action of resistors R2 and R3.With this configuration, when the vehicle speed increases during acceleration, this state is immediately detected. However, when the vehicle speed decreases from the previous state during deceleration, it is delayed and input to the negative input of the operational amplifier 12.
Circuit A has the characteristic of gradually changing the input voltage of the negative input of No. 2 to become smaller.

意味で回路Ｂはヒステリメス特性を有するものである。Circuit B, which is the next stage of circuit A and consists of an operational amplifier 12, etc., has the following hysteresis characteristic. A voltage obtained by appropriately setting this adjustment variable voltage dividing resistor R5 is input, and this positive input terminal and the output terminal of the operational amplifier 12 are connected to the resistor R6.
is configured to be connected via. Therefore, in circuit B, the set voltage obtained by the resistor R5 in the operational amplifier 12 is compared with the voltage at point q, which is the terminal voltage of the capacitor C0 related to the vehicle speed, and the voltage related to the vehicle speed is larger than the set voltage. The switching instruction circuit 8
A switching signal 81 for switching the switch 2a of the switching circuit 2 from the sensor 3 to the sensor 4 is output to the terminal r. As a result, when the vehicle speed becomes higher than the predetermined speed vI for switching set by the acceleration resistor, the reference level for vehicle height adjustment is switched from "high" to "1 low", and this first vehicle height adjustment device is activated by the sensor 4. Vehicle height adjustment is started based on the output signal, and the vehicle height is adjusted to an appropriate position relative to the reference level of "1 low". On the other hand 1, operational threat amplifier 1,
Since the positive input terminal of No. 2 is connected to its output side via the resistor R6, when the switching signal a is generated, the set voltage applied to the positive human power decreases, and the vehicle speed is accelerated in this one step. If the speed is slightly reduced after 1 minute, the speed will be slightly lower than the above speed vl.
The first switching vehicle speed when switching to V is not the above v1, but V
2 (vz<vt). Therefore, with this configuration, once the vehicle height is automatically switched to "High J or 1 Low" during acceleration, if it is 1, then after acceleration (the above mentioned vehicle height adjustment due to vehicle speed fluctuation due to slight acceleration/deceleration) It becomes possible to prevent excessive switching, and in this sense, circuit B has hysteresis characteristics.

再び「低」から「高」の適正位置に切り換えられる。The mechanism that can automatically switch the base level of vehicle height adjustment, which includes the vehicle speed sensor 9 and the switching vehicle speed setting circuit 10 and has the configuration and function as described above, operates based on the vehicle speed state of the vehicle. While the changeover switch 2a is connected to the sensor 3, the vehicle speeds up to the set speed v1.
When the level becomes higher, a switching signal s1 is output, which connects the switch 2a to the sensor 4 side through the action of the switching instruction circuit 80, thereby adjusting the vehicle height based on the "low" reference level and setting the vehicle height to "low". This will be the appropriate position. At this time,
Due to the above-mentioned hysteresis characteristic of circuit B, even if the vehicle speed fluctuates, the vehicle height adjustment is not switched, and even if the vehicle speed rapidly decreases below v2 due to sudden braking, etc., due to the above-mentioned delay effect of circuit A Reference level is “low” in switching circuit 2
It is not possible to switch from ``high'' to ``high''. When the vehicle is decelerated and a certain period of time longer than the delay time has elapsed, the switching signal 81 disappears, so the sensor connection changes from 4 to 3, and unless it is switched by operating the manual switch γ, the vehicle height will return to "low". ” to the appropriate position of “High”.

For example, the number of switching stages is not limited to two, the switch 9a can also be used as a switch sensor for a vehicle speed meter, circuit A has a delay effect only in one direction, and circuit B has another hysteresis characteristic. It is also possible to use one circuit instead.
