Abstract

PURPOSE:To prevent a vehicle from falling into an unstable running condition by a method wherein an alarm device is operated to alarm it when a condition in which an air pressure for an air suspension device is below a predetermined value and a car speed is exceeding a predetermined value is continued during a predetermined period of time or more. CONSTITUTION:In case the system is applied to an automatic two-wheeled vehicle, a plurality of damping air cylinders 2a, 2a' in an air suspension device 2 for a rear wheel are communicated with each other in an air pressure detecting device 4 through respective communicating tubes 3, 3'. This detecting device 4 generates an output signal when the air pressure of the suspension device 2 is lower than a predetermined value and input it into a signal processor 14. A signal from a car-speed discriminator 7, generating an output signal when the car-speed has exceeded a predetermined value, is inputted into the signal processor 14 also through a car- speed discriminating circuit 13. When a condition, in which the air pressure for the suspension device 2 is lower than the pedetermined value and the car-speed is exceeding the predetermined value, is continued during a predetermined period of time or more, an output signal to operate the alarming device 15 is generated.
