A lawn care vehicle, comprising: a rack; a seat disposed above the rack and configured to support an operator; a wheel set at least partially disposed below the rack and configured to drive the rack to move, wherein the wheel set comprises at least two driving wheels (141L, 141R); a running motor (143L, 143R) configured to drive at least one of the at least two driving wheels to rotate and comprising a stator and a rotor; a supply device at least configured to supply a power source to the running motor; an operating assembly at least partially disposed above the rack and configured to be operated by the operator to set a target state of the lawn care vehicle and one of a target rotational speed or a target torque of the running motor, wherein the target state comprises one of a forward state, a stop state, or a backward state; wherein the operating assembly has a target rotational speed detection module configured to detect said target rotational speed; a driver circuit (53L, 53R) electrically connected to the running motor and configured to distribute electric power of the supply device to multiphase windings on the stator in a preset logical relationship so that the running motor is capable of generating continuous torque; a first detection device configured to detect an actual measured rotational speed of the at least one of the at least two driving wheels or the running motor in real time; a current detection module configured to detect three-phase currents of the running motor; and a control module configured to: receive the actual measured rotational speed sent by the first detection device and the target rotational speed set by the operating assembly; and based on the actual measured rotational speed of the at least one of the at least two driving wheels sent by the first detection device at a first preset time interval, one of the target rotational speed or the target torque set by the operating assembly, and a rotor position of the running motor, perform dynamic adjustment on currents applied to the multiphase windings to make the driver motor reach or basically reach the target torque set by the operating assembly within a preset time; characterized in that said target rotational speed detection module and said control module are connected through a bus, wherein a communication frame rate of the bus has a value range of 100 Hz to 3000 Hz. a rack;
