摘要： A vehicle height adjustment apparatus includes a control device. The control device controls the opening degree of the solenoid valve to allow a movement amount of the support member to reach a movement amount target value that corresponds to the vehicle height set in advance, in accordance with the weight applied to the vehicle. The control device controls the opening degree of the solenoid valve to change the movement amount of the support member based on a difference between a value based on the information related to the vehicle height and a vehicle height-related target value, on condition that the movement amount of the support member reaches the movement amount target value and the value based on the information related to the vehicle height obtained by the information obtaining device does not reach the vehicle height-related target value that corresponds to the vehicle height set in advance.

摘要： A suspension controller includes a target current setting unit, a current limitation setting unit, a current outputting unit, a current detector, and an estimated temperature calculator. The target current setting unit sets a target current value. The current limitation setting unit sets a current limitation value. The current outputting unit supplies a solenoid with a current that is based on the target current value, the current limitation value, and a power supply voltage. The solenoid controls a damping force of a suspension. The current detector detects a current value of the current supplied to the solenoid. The estimated temperature calculator calculates an estimated temperature of the solenoid based on the current value detected by the current detector so that the current limitation setting unit changes the current limitation value based on the estimated temperature.

摘要： Systems and methods for determining a status of a vehicle suspension system are disclosed. A vertical acceleration of the vehicle relative to a road surface is determined based on a position of a vehicle body. Based on a predetermined period of time, a peak value that corresponds to the vertical acceleration is calculated. The peak value is compared to a target peak value and, when the peak value meets a preset criteria, a notification of potential suspension degradation is issued.

摘要： A method and a system generates signals for influencing the movement of the body of a vehicle, wherein the chain of movements of which can be controlled or adjusted. The movement of the vehicle body is determined by sensors in relation to at least three wheels of the motor vehicle and the vertical acceleration of the vehicle body, the sensor signals that correspond to the determined sensor values are fed to a shock absorber controller which delivers at least one control signal to control actuators, in particular semi-active or active shock absorbers which are used to influence the movement of the body. The control signal for controlling the actuators is determined by the shock absorber controller from the sensor signals, with the aid of condition-dependent adjustment algorithms, taking into consideration current and/or expected conditions in conjunction with selectable requirements for the movement of the vehicle body and driving safety requirements.

摘要： A control method and apparatus which detects a solenoid current as a voltage, and PWM-controls a transistor for a solenoid such that the detection voltage becomes a target voltage. A feedback gain, used for setting PWM signal output time, is set in accordance with the difference between the detection voltage and the target voltage such that the greater the difference becomes, the greater the feedback gain becomes. Further, a detection voltage after a predetermined period is estimated based on the change of detection voltage from the past. If the estimation value overshoots the target voltage, a difference B between the detection voltage and the target voltage and a difference C between the detection voltage and the estimation value are obtained, and the feedback gain is varied by multiplying the feedback gain by the ratio B/C between the these differences.

摘要： In a vehicle height adjustment device, an operation amount of an actuator increases in accordance with supplied current, a detector detects a vehicle height, and a changer changes the vehicle height in accordance with the operation amount of the actuator. The changer shifts to a vehicle height increasing state or to a vehicle height decreasing state based on whether the operation amount is not higher than a predetermined amount. A controller controls the current supplied to the actuator to make the relative position have a target value. The controller determines a target current supplied to the actuator based on a control map that correlates a deviation between the target value of the relative position and a detection value to the target current.

摘要： An air suspension control system for a vehicle such as an ambulance, a bus or a semi-truck. The control system includes an air supply, such as a compressor, which is configured to pneumatically communicate with a lift mechanism for moving the lift mechanism between a ride height position and a kneeling position and vice versa. The controller is configured to return or recover the lift mechanism to its ride height position during the time the lift mechanism is moving from its ride height position to its kneeling position by only deactivating the kneel input. The controller is configured to return or recover the lift mechanism to its ride height position after the lift mechanism has reached kneeling position by both deactivating the kneel input and activating the recover trigger input by pressing the brake pedal. The control system also has a transmission park feature and an ignition timer feature.
