The invention provides a gear limiting system, a vehicle and a gear limiting method. The system comprises a vehicle speed sensor, a rotating speed sensor, a processor, a transmission control unit TCU and an automatic transmission; and the output end of the rotating speed sensor is connected with the first input end of the processor, the output end of the vehicle speed sensor is connected with the second input end of the processor, the first output end of the processor is connected with the first input end of the TCU, the second output end of the processor is connected with the second input end of the TCU, and the output end of the TCU is connected with the input of the automatic transmission. By means of the gear limiting system, the vehicle and the gear limiting method, the gear of the automatic transmission can be limited when needed, and potential safety hazards of the automatic gear shifting vehicle are reduced.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a gear position limiting system, a vehicle and a gear position limiting method. Background technique [0002] For general vehicles, the gear position of the transmission (also known as gearbox) directly affects the speed of the vehicle, mainly reflected in the fact that each gear has a corresponding allowable speed range, the higher the gear, the higher the maximum allowable speed , the lower the gear, the lower the maximum allowable vehicle speed. In current vehicles such as automatic shift vehicles, the gear position is mainly automatically adjusted by the Transmission Control Unit (TCU) according to the engine speed and vehicle speed. For example, in a certain gear, the engine speed increases. , the vehicle speed value will also increase accordingly. When the rotational speed and vehicle speed both increase to a certain level, the TCU will increase the gear of the transmi...
