Title: Antiskid control device for all wheel drive vehicle
Inventor: YASUNO YOSHIKI
IPC: B60T8/70
Filed: 1986-03-03
Abstract: PURPOSE:To make it possible to precisely perform antiskid control at each wheel to prevent the efficiency of braking from deteriorating, by controlling the rear wheels in such a way that the rate of boost-up of brake pressure at one of them is lower than that at the other during boost-up of brake pressure after antiskid control. CONSTITUTION:An antiskid control circuit 6 is fed with a signal A/S indicating that a right rear wheel antiskid control circuit 10 is on antiskid control, in addition to signals indicating a left rear wheel speed VWL, left rear wheel acceleration alphaWL, and a desired wheel speed Vm. Further, during boost-up of brake hydraulic pressure after antiskid control, the boost-up cycle period is made to be longer at the left rear wheel than at the right rear wheel so that the brake hydraulic pressure at the right rear wheel is increased before that at the left rear seat is increased, resulting in that pressure reduction is continued until the right rear wheel speed becomes such as VWR>Vm. Meanwhile the brake hydraulic pressure at the left rear wheel is always maintained to be lower than that at the right rear wheel due to synchronized pressure reduction and boost-up cycle period at both right and left rear wheels, so that the VWL becomes equal to the vehicle speed VWN, thereby a precisely estimated speed may be obtained.

Abstract: PURPOSE:To prevent the breakdown of a compressor, refrigerant hose and the like, by a method wherein the temperature of discharged refrigerant of the compressor is detected and a solenoid valve, provided in a bypass passage, bypassing a heat exchanger in a refrigerator, is controlled based on the detected temperature. CONSTITUTION:When the temperature of the discharging refrigerant of a refrigerant compressor 3 has exceeded a preset temperature due to the fluctuation of the rotating speed of an engine or the change of an atmospheric temperature, in a cooling cycle, a temperature sensor 21 is put ON and a solenoid valve 31 is opened.

According to this operation, the temperature of the discharging refrigerant of the refrigerant compressor 3 is risen. The temperature of the discharging refrigerant of the refrigerant compressor 3 may be kept at the set temperature in such a manner.
