1. A vehicle comprising:
a tilting mechanism;
two front wheels that are on two lateral sides of said tilting mechanism and that are spaced apart from each other in a lateral direction of said vehicle, said tilting mechanism being configured to allow said two front wheels to tilt;
a control switch that is operable to generate an operation signal;
a warning unit; and
a controller that is electrically connected to said control switch to receive the operation signal therefrom, that is electrically connected to said tilting mechanism and said warning unit to control operations thereof, and that is configured to, in response to receipt of the operation signal, transmit a control signal to said tilting mechanism for making said tilting mechanism operate in one of an unlocked state and a locked state,
wherein, after said vehicle is powered on, said controller is further configured to, when said controller has continuously received the operation signal for a predetermined reception time period, determine that said control switch is abnormal, stop transmitting the control signal to said tilting mechanism and control said warning unit to output a warning signal,
wherein said tilting mechanism includes
two transverse bars that are spaced apart from each other in an up-down direction of said vehicle,
two lateral bars that are spaced apart from each other in a left-right direction of said vehicle and that are pivotally connected to said transverse bars,
two dampers that are respectively connected to said lateral bars, said front wheels being mounted respectively on said dampers,
a tilt-locking unit that is connected to said transverse bars and that is configured to be driven to allow or restrict movement of said lateral bars with respect to said transverse bars,
two damper-locking units that are mounted respectively on said dampers and that are configured to be driven to respectively lock or unlock said dampers, and
a driving mechanism that is electrically connected to said controller for receiving the control signal therefrom, and that is configured to, in response to receipt of the control signal from said controller, drive said tilt-locking unit and said damper-locking units,
wherein said driving mechanism includes a hydraulic pump that is configured to drive said tilt-locking unit and said damper-locking units, a cam that is configured to be driven to drive said hydraulic pump, and a motor that is connected to said cam and that is electrically connected to said controller for receiving the control signal from said controller to drive said cam.
