Abstract
A vehicular height control system, according to the invention employs mutually different first and second target vehicular heights, about which normal vehicular height range is determined. The first target height is used during normal vehicle driving conditions, in which the power is supplied. On the other hand, the second target height is used during vehicular parking. The vehicular height control system according to the invention is responsive to turning OFF of the power supply to perform height adjustment utilizing the second target height to sligthly raise the vehicular height and maintains the raised height during parking. In order to maintain the vehicular height at a slightly higher level, slightly greater suspension force than that required for maintianing the vehicular height at a height level in the normal driving condition is provided. This reduces height adjustment when power supply is resumed.
