Description
本提案係關於一種車輛控制系統，特別是一種車輛姿態及高度調整系統。 This proposal relates to a vehicle control system, and more particularly to a vehicle attitude and height adjustment system.
一般調整汽車高度之裝置，除了傳統機械彈簧之外，亦可利用氣壓裝置及油壓裝置調整高度。惟氣壓調壓不易，且調整高度無法精確控制。因此，為了精確控制汽車高度的調整量，一般會增加電子感測器及電子控制器來感測並控制各壓缸的作動。然而，電子感測器及電子控制器的使用壽命較短，亦較易受震動的影響而喪失感測或控制的功能，當電子感測器或電子控制器損壞時，汽車高度調整的精確度就會下降，甚至會使汽車喪失高度調整的功能。此外，以往調整汽車高度之裝置亦存在因壓缸數量過多而造成控制系統過於複雜的問題。因此，如何簡化汽車高度控制的複雜度並提升汽車高度控制的穩定性，實為研發人員應重視的問題之一。 Generally, the height adjustment device can be adjusted by using a pneumatic device and a hydraulic device in addition to the conventional mechanical spring. However, the pressure regulation is not easy, and the adjustment height cannot be precisely controlled. Therefore, in order to accurately control the adjustment amount of the vehicle height, an electronic sensor and an electronic controller are generally added to sense and control the actuation of each cylinder. However, electronic sensors and electronic controllers have a short life span and are more susceptible to vibration and loss of sensing or control. When the electronic sensor or electronic controller is damaged, the accuracy of the vehicle height adjustment is high. It will drop and even make the car lose its height-adjusting function. In addition, in the past, the device for adjusting the height of the vehicle also has a problem that the control system is too complicated due to the excessive number of cylinders. Therefore, how to simplify the complexity of vehicle height control and improve the stability of vehicle height control is one of the issues that R&D personnel should pay attention to.

At the same time, the shock absorber oil body flows into the suspension oil tank 593 of the fourth liquid pressure cylinder 540 and the suspension oil tank 593 of the eighth liquid pressure cylinder 580 to drive the fourth liquid pressure cylinder 540 and the eighth liquid pressure cylinder 580 to have the same elongation. At this time, the rear of the car is raised. As a result, the vehicle body 20 assumes a posture of a front low and a rear high with the ground 30 at a second angle θ 2 . Wherein, in the process of tilting the vehicle body 20, the second liquid pneumatic cylinder 520, the third liquid pneumatic cylinder 530, the sixth liquid pneumatic cylinder 560 and the seventh liquid pneumatic cylinder 570 are automatically adjusted to the extent of the inclination of the vehicle body 20 to The respective states of the first to fourth liquid-pneumatic cylinders 510 to 540 are adjusted to be in a linear relationship from small to large.

The fluids of the second liquid pressure cylinder 520 and the third liquid pressure cylinder 530 are returned to the second vehicle height adjustment hydraulic cylinder 340a, and the fluids of the sixth liquid pressure cylinder 560 and the seventh liquid pressure cylinder 570 are returned to the second vehicle height adjustment hydraulic cylinder. 340b, to simultaneously shorten the same first liquid pressure cylinder 510, second liquid pressure cylinder 520, third liquid pressure cylinder 530, fourth liquid pressure cylinder 540, fifth liquid pressure cylinder 550, sixth liquid pressure cylinder 560, The lengths of the seventh liquid pneumatic cylinder 570 and the eighth liquid pneumatic cylinder 580 are used to shorten the distance between the vehicle body 20 and the ground 30. The height of the vehicle body 20 is lowered, and the height of the vehicle body 20 is reduced at the same time, and the height of the vehicle body 20 can be prevented from being tilted or unbalanced when the vehicle body 20 is lowered.
值得注意的是，由於二第一車高調整液壓缸330a、330b與二第二車高調整液壓缸340a、340b的流量變化皆相等，故第一液氣壓缸510、第四液氣壓缸540、第五液氣壓缸550及第八液氣壓缸580的伸長量或縮短量皆相同而讓車體20前後保持相同高度及左右保持相同高度，進而維持車體20平衡。 It is to be noted that since the flow changes of the two first vehicle height adjusting hydraulic cylinders 330a, 330b and the two second vehicle height adjusting hydraulic cylinders 340a, 340b are equal, the first liquid pneumatic cylinder 510, the fourth liquid pneumatic cylinder 540, The elongation or the shortening amount of the fifth liquid pressure cylinder 550 and the eighth liquid pressure cylinder 580 are the same, and the vehicle body 20 is maintained at the same height in front and rear and at the same height, thereby maintaining the balance of the vehicle body 20.
本提案的好處在於僅需透過流體驅動裝置100的流量控制與姿態調整液壓缸320a、320b的流量分配至各液氣壓缸510~580即可達成車輛的姿態調整。並且，僅需透過流體驅動裝置100的流量控制與各車高調整液壓缸330a~340b的流量分配至各液氣壓缸510~580即可達成車輛的高度調整。如此一來，可有效地將液氣壓缸的數量減少至8個，及開關閥的數量減少至10個，進而簡化車輛控制的複雜度。 The advantage of this proposal is that the attitude adjustment of the vehicle can be achieved only by the flow control of the fluid drive device 100 and the flow rate of the attitude adjustment hydraulic cylinders 320a, 320b being distributed to the respective hydraulic cylinders 510-580. Further, the height adjustment of the vehicle can be achieved only by the flow rate control of the fluid driving device 100 and the flow rates of the respective vehicle height adjusting hydraulic cylinders 330a to 340b being distributed to the respective liquid pneumatic cylinders 510 to 580. In this way, the number of hydraulic cylinders can be effectively reduced to eight, and the number of switching valves can be reduced to ten, thereby simplifying the complexity of vehicle control.
此外，本提案係透過流體驅動裝置100的流量控制來調整車輛的姿態與高度，無需透過電子控制元件來控制，而流體驅動裝置100的流量控制的可靠度較電子控制元件的可靠度高，故能夠提高車輛姿態及高度調整系統的控制穩定性。 In addition, the present proposal adjusts the attitude and height of the vehicle through the flow control of the fluid drive device 100 without being controlled by the electronic control unit, and the reliability of the flow control of the fluid drive device 100 is higher than the reliability of the electronic control unit. It can improve the control stability of the vehicle attitude and height adjustment system.
根據上述本提案所揭露的車輛姿態及高度調整系統，車輛姿態及高度調整系統僅需透過流體驅動裝置的流量控制與姿態調整液壓缸的流量分配至各液氣壓缸即可達成車輛的姿態調整。並且，僅需透過流體驅動裝置的流量控制與各車高調整液壓缸的流量分配至各液氣壓缸即可達成車輛的高度調整。如此一來，可有效地將液氣壓缸的數量減少至8個， 及開關閥的數量減少至10個，進而簡化車輛控制的複雜度。 According to the vehicle attitude and height adjustment system disclosed in the above proposal, the vehicle attitude and height adjustment system can achieve the attitude adjustment of the vehicle only by distributing the flow rate of the fluid drive device and the flow rate of the attitude adjustment hydraulic cylinder to each liquid pressure cylinder. Moreover, the height adjustment of the vehicle can be achieved only by the flow control of the fluid drive device and the flow rate of each of the vehicle height adjustment hydraulic cylinders being distributed to the respective liquid pressure cylinders. In this way, the number of hydraulic cylinders can be effectively reduced to eight. The number of on-off valves is reduced to 10, which simplifies the complexity of vehicle control.
此外，車輛姿態及高度調整系統係透過流體驅動裝置的流量控制來調整車輛的姿態與高度，並不是靠電子控制元件來控制，而流體驅動裝置的流量控制的可靠度較電子控制元件的可靠度高，故能夠提高車輛姿態及高度調整系統的控制穩定性。 In addition, the vehicle attitude and height adjustment system adjusts the attitude and height of the vehicle through the flow control of the fluid drive device, which is not controlled by the electronic control component, and the reliability of the flow control of the fluid drive device is more reliable than that of the electronic control component. High, it can improve the control stability of the vehicle attitude and height adjustment system.
