The invention provides a hydraulic follow-up control system and a vehicle. The hydraulic follow-up control system comprises a first hydraulic pump, a first reversing valve, a second reversing valve, a cartridge valve, a hydraulic motor and an oil tank. An oil suction port of the first hydraulic pump is communicated with the oil tank, an oil outlet of the first hydraulic pump is communicated with an oil inlet of the first reversing valve, two working oil ports of the first reversing valve are respectively communicated with two working oil ports of the hydraulic motor, and an oil return port of the first reversing valve is communicated with the oil tank; an oil inlet of the second reversing valve is communicated with an oil outlet of the first hydraulic pump, a working oil port of the second reversing valve is communicated with a control oil port of the hydraulic motor and a control oil port of the cartridge valve, and two main oil ports of the cartridge valve are respectively connected between two working oil ports of the hydraulic motor. The invention provides a hydraulic follow-up control system and a vehicle. The hydraulic follow-up control system can prevent a hydraulic motor from sucking air.
