A wireless communication device, a wireless communication method, and a program are provided in which even when communications in a plurality of kinds of wireless communication modes are performed via a single antenna, the communications in these wireless communication modes can coexist and the communications can be appropriately performed. In the case where communications in a BT wireless communication mode in which processing of searching for registered target devices 4 is repeatedly executed at predetermined execution intervals in order to connect to the registered target devices 4 and in a Wi-Fi wireless communication mode are performed via a single antenna 21, the execution intervals of searching for the registered target devices 4 via BT are changed to a value larger than a reference interval during at least a part of a period during which Wi-Fi communication is being performed or Wi-Fi communication is enabled.

A vehicle-height adjustment system controls a tank pressure based on a vehicle height and an inside temperature which is a temperature in the system. Increase in the inside temperature increases the tank pressure. When the tank pressure becomes higher than a discharge start threshold value, air discharge control is executed. In the case where the inside temperature thereafter lowers, the tank pressure also lowers, which may cause air intake control. To solve this problem, the discharge start threshold value is set to be larger when the inside temperature is high than when the inside temperature is low. This control reduces execution of the air discharge control, resulting in reduction in needless operations.

This oil pump includes an inner rotor in which a plurality of vanes is housed such that the plurality of vanes is slidable in a radial direction, an outer rotor connected with tip ends of the plurality of vanes, a first volume-changing part, which is provided between the inner rotor and the outer rotor, a volume of which is changed in response to eccentricity of the inner rotor with respect to the outer rotor, and a second volume-changing part, which is provided in the outer rotor, a volume of which is changed by a change in a distance between vane-connecting parts adjacent to each other in a circumferential direction in response to the eccentricity of the inner rotor with respect to the outer rotor. Each of a plurality of outer rotor pieces, which is annularly connected to each other, of the outer rotor includes a first engaging part provided in a first end surface in an axial direction and a second engaging part provided in a second end surface in the axial direction and being capable of engaging with the first engaging part of an adjacent one of the outer rotor pieces, and the plurality of outer rotor pieces is circumferentially arranged in a state where the first engaging part and the second engaging part of the outer rotor pieces being adjacent to each other engage with each other such that a distance therebetween in the circumferential direction is variable.

A vehicle-height control system executes down control for lowering a vehicle height. In the case where the vehicle height is lowered, when a tank pressure which is a pressure of a pressure medium stored in a tank (34) is lower than a set pressure, air is discharged from an air cylinder (2) and supplied to the tank (34), but when the tank pressure is higher than or equal to the set pressure, air is discharged from the air cylinder (2) to the outside. Thus, even when the tank pressure is greater than or equal to the set pressure at time t1, the down control is continued without being suspended. Accordingly, a time required for the down control can be reduced by time T when compared with the case where when the tank pressure becomes greater than or equal to the set pressure during the down control, the down control is suspended, and discharge control is executed to discharge the pressure medium from the tank (34) to the outside.

Patent

In a vehicle-height control system, an actuator-side passage is connected to a fluid supply and discharge device. A vehicle-height control actuator is connected to the actuator-side passage via a vehicle-height control valve. At a start of vehicle height control, the vehicle-height control valve is switched from a closed state to an open state after the actuator-side passage is fluidically coupled with the air supply and discharge device. For example, at a start of up control, a tank of the fluid supply and discharge device is fluidically coupled with the actuator-side passage to increase a pressure of fluid in the actuator-side passage. This operation makes it difficult for fluid to be discharged from the vehicle-height control actuator to the actuator-side passage when the vehicle-height control valve is thereafter switched from the closed state to the open state. Accordingly, unintentional lowering of vehicle height can be prevented.
