Problems solved by technology
[0004] An object of the present invention is to provide a gear recognition device and a vehicle for a vehicle to solve the problem that the parking position sensor in the prior art has poor anti-interference ability due to electromagnetic induction and is easily affected by surrounding environmental factors. The difference in the signal collected by the position sensor causes the TCU to make a wrong judgment

Embodiment Construction
[0030] The position recognition of the gear shift fork of the vehicle is generally used in the field of automatic transmission control. The control system completes the control of the vehicle's driving direction and automatic transmission through the execution unit according to the sensing signal of the gear shift fork. Similarly, when the parking fork of the vehicle is in the parking state, the position sensor used to collect the parking fork will transmit the collected signal to the transmission control unit to determine whether the vehicle is in the parking state, thereby ensuring that the vehicle Parking safety. image 3 It is a schematic structural principle diagram of the first recognition state of a gear position recognition device for a vehicle according to an embodiment of the present invention, and is used to identify the actual position of the gear position of the parking mechanism of the vehicle, so as to solve the problem in the prior art Due to the poor anti-inte...

The invention provides a gear recognition device for a vehicle and the vehicle, and relates to the technical field of recognition. The gear recognition device is used for recognizing the actual position of the gear of a parking mechanism. The vehicle comprises a transmission with a shifting fork. The gear recognition device comprises a sensor arranged in the transmission of the vehicle, and a controller which is in communication connection with the sensor, wherein the sensor is provided with a trigger switch, the sensor is configured to determine the gear position where the shifting fork is located according to the state of the trigger switch, and a voltage signal matched with the gear position where the shifting fork is located is output; and the controller is configured to be used for receiving the voltage signal output by the sensor and used for outputting an indication signal according to the voltage signal, wherein the indication signal is used for representing the actual positionof the gear of the parking mechanism of the vehicle. The gear positions include the parking gear and the non-parking gear. By means of the gear recognition device for the vehicle and the vehicle, theproblem that due to the electromagnetic induction manner, a parking position sensor in the prior art is poor in anti-jamming capability and is prone to being influenced by the surrounding environmentfactor, consequently, signals collected by the position sensor are abnormal, and the judgment of a TCU is wrong is solved.
Description
technical field [0001] The invention relates to the technical field of recognition, in particular to a gear position recognition device for a vehicle and the vehicle. Background technique [0002] In AT (automatic transmission) or DCT (dual clutch transmission), the parking mechanism is controlled by the gear selection actuator or the shift cable of the AT or dual clutch automatic transmission, and drives the pawl with the pawl rotary shaft as the axis The center rotates and meshes with the parking ratchet to lock the output shaft or differential to achieve the purpose of parking. At this time, the position sensor of the parking mechanism will output the signal it collects to the TCU (transmission control unit ), so as to identify the actual position of the parking mechanism through the TCU. [0003] At present, the position sensor of the parking mechanism usually uses the principle of electromagnetic induction to identify the actual position of the parking mechanism. figu...
