The invention provides a stroke control system for a supporting leg oil cylinder and an automobile crane with the stroke control system. The stroke control system for the supporting leg oil cylinder comprises the supporting leg oil cylinder and a first reversing valve, wherein a first working oil opening of the first reversing valve is communicated with a rod cavity of the supporting leg oil cylinder, and a second working oil opening of the first reversing valve is communicated with a rodless cavity of the supporting leg oil cylinder; and the stroke control system for the supporting leg oil cylinder further comprises a detection device, a processing unit and a control device. the detection device is used for detecting the stroke of the supporting leg oil cylinder and sending out a detection signal when the stroke reaches the preset valve; the processing unit is connected with the detection device and is used for receiving the detection signal and sending out a control signal according to the detection signal; and the control device is connected to a connecting pipeline between the supporting leg oil cylinder and the first reversing valve, and used for receiving the control signal and controlling the supporting leg oil cylinder to stop action according to the control signal. According to the technical scheme, the stroke of the supporting leg oil cylinder can be automatically controlled, and the automation control over the stroke of the supporting leg oil cylinder is achieved.
