The invention discloses a steering wheel turning angle display circuit and device, a steering wheel and a vehicle. The steering wheel turning angle display circuit specifically comprises a Hall switch group module, a lamp group module and a steering wheel turning angle signal processing module. The Hall switch group module is used for detecting the turning angle of the steering wheel through a plurality of paths of magnetic induction signals generated by position changes of a plurality of Hall switches and a magnet; the magnetic induction signal is sent to a steering wheel corner signal processing module; the lamp group module displays the turning angle of the steering wheel by turning on or off one or more indicator lamps; the lamp group module receives one or more paths of level signals sent by the steering wheel corner signal processing module to drive an indicator lamp to be lightened; a logic circuit is arranged in the steering wheel corner signal processing module; a magnetic induction signal from the Hall switch group module is converted into a level signal for driving an indicator light to be lightened through a logic circuit in the steering wheel corner signal processing module. The problem that a novice driver does not know the current steering wheel turning angle is solved.
